 (Kead May L'7, 1886.) 
 
 As stated in his preliminary report, 1 Dr. Dawsou's geological explorations of certain 
 parts of the coast of British Columbia, in the summer of 1885, in which he was assisted 
 by Mr. D. B. Bowling, were prosecuted by means of a schooner. In the intervals of 
 the more purely geological work, this mode of locomotion afforded many opportunities, 
 which were utilized to their fullest extent, for collecting marine invertebrata, on the 
 shore, by the towing net or by the dredge. The title of the present paper sufficiently 
 indicates the area examined, at many points within which collections were made at low 
 tide. The material collected by the towing net, being to a large extent microscopical in 
 its character, has not yet been examined. The dredge was used successfully at depths of 
 of from seven to fifty fathoms, at the following localities :

 19. Quatsino Sound, off Entrance Island, in from thirty to fifty fathoms, mud and sand. 
 20. Forward Inlet, Quatsino Sound, in ten to twenty fathoms, mud. 
 
 Owing to the systematic way in which the collections were made, the series of 
 marine invertebrata now reported upon is by far the most extensive and important that 
 has yet been made by any of the exploring parties of the Survey. The Crustacea, with the 
 exception of the minute and for the most part larval forms collected in the towing net, 
 have been kindly examined by Prof. S. J. Smith, of Yale College, who will report on them 
 separately. The sponges, hydroids (with one exception), polyzoa, and worms, have not 
 yet been studied. Including the foraminifera, the number of species that have been iden- 
 tified so far is approximately as follows :

 At station No. T, the sand which came up in the dredge, when washed and examined 
 under the microscope, was found to be unusually rich in diatomaceae. Among these, 
 connected frustules of Himantidium, Tabellaria and Grammatophora marina are frequent, 
 associated with separate frustules of Arachnoidiscus Ehrenbergii (rare), Amphitetras antedilu- 
 viana, and of species belonging to the genera Amphora, Campylodiscus, Coscinodiscus, Fragilaria, 
 Gyrosigma, Licmophora, Navicida, Podosphainia, Surirella and Tric&ratium, 
 
 Samples of the sand, mud, etc., dredged from the bottom at ten of these stations were 
 saved to be examined for foraminifera. The species from the Vancouver district do not 
 appear to have previously been studied by any naturalist, and the present list of the 
 foramiuifera of that region, though making no pretence to completeness, is believed to be 
 the first that has yet been published. The largest and most conspicuous form is the 
 Rhabdammina abyssorum of M. Sars, which was taken abundantly at three of the stations. 
 
FEOM THE COAST OF BEITISH COLUMBIA. 113 
 
 It had been dredged by the writer before, in 1873, at a depth of 200 fathoms in the Gulf 
 of St. Lawrence. Other remarkable forms are double examples of Discorbina I ttriairnsif, 
 which are far from uncommon in Dr. Dawsou's dredgings ; large varieties of CrisleHnriii 
 rnltraln. and a Frondirularia which, although common a.s a fossil in the Chalk of Europe 
 and England, was previously unknown as a living species. 
 
 Among the echiuodermata, the most interesting species collected is the Astrogonium 
 grnnii/are, which is new to the fauna of the Pacific. 
 
 Of the lamellibranchiate bivalves, two, vix., Pecten Alaskensis and Yoldia thradceformis, 
 are arctic or subarctic shells which had not previously been taken so far to the south as 
 the Vancouver region, while, on the other hand, Limntiiln xitbauriculata and Ledu acutn are 
 species which have not hitherto been recorded as occurring so far to the north, on the 
 west coast of North America. 
 
 The number of species of gasteropoda collected is unusually large, and among these, 
 Leptochiton cnncellatus, Bela violacea, Cancellaria ciri'inni-imiii, Admete viridula, and Sipfio 
 VerkruzKnl are northern forms new to the Vancouver district ; while Solariella peramabilis 
 ami Bin-twin sulik'iitiis are Californian shells now for the first time placed upon record as 
 living within it. Astarte undata and Eulima incurva (=distorta auct.) if correctly identified, 
 seem to be new to the fauna of the west coast of North America ; Margarita cidaris, of which 
 a line series w r as obtained, was previously known only from a single specimen ; and 
 Cadulus aben-anx and Leptochiton pinictatus are here described for the first time. 
 
 It would appear that the outer and exposed western coast of Vancouver Island is 
 tenanted by a somewhat dilfercnt assemblage of marine invertebrata from that which lives 
 in its eastern, south-eastern and more land-locked waters. So far, Tellina Bodegensis, 
 Cadulus aberrant, Pachypoma gibberosum, Chlorostoma funebrale and Olive/la biplicata have been 
 found by the Survey collectors on the west and north coast of the Island only, while 
 Acmii'ii iitstiiliilif.. Cri/i>lobranchia concenlrirn, IJnliotis Kamtschatkana and Phorcus nulligo, though 
 not exclusively confined to the outer coast, appear to be rare in its eastern and south- 
 eastern waters. The exact geographical distribution of the different species around the 
 coast of Vancouver Island, however, has yet to be ascertained, and the preceding remarks 
 have only been written with the view of directing attention to the subject. 
 
 For critical and valuable suggestions in regard to some of the mollusca collected, and 
 for the identification of eight species of gasteropoda, the writer is indebted to Mr. W. H. 
 Call of the United States National Museum at Washington. 
 
 The following is a list of the species that have been identified so far. 
 
 FORAMINIFERA. 
 
 MILIOLTNA SEMINULTJM, L. Strait of Georgia at station No. 2, Discovery Passage at station 
 No. 7, and Queen Charlotte Sound at station No. It, one specimen at each. 
 
 MIL.IOLINA FERUSSACII, fOrbigny. "With the preceding at station No. 17, one specimen. 
 
 RIIABDAMMINA ABYSSORUM, M. Sars. Strait of Georgia at stations Nos. 4 and 5, Queen 
 Charlotte Sound at station No. 17, and Quatsino Sound at station No. 20, abundant 
 at each.

114 WHITE AVES ON MAEINE INVEKTEBRATA, ETC., 
 
 HAPLOPHRAGMIUM CANARIENSE, <Orbigny. Strait of Georgia at station No. 3, Discovery 
 Passage at station No. 7, Queen Charlotte Sound at station No. 17, and Quatsino 
 Sound at station No. 20, not rare. 
 
 TROOHAMMINA SOJTAMATA, Jones and Parker. Strait of Georgia at station No. 2, and 
 Quatsino Sound at station No. 19, not common. 
 
 BULIMINA PYRXJLA, (TOrbigny. Johnstone Strait at station No. 9, five specimens. 
 LAGENA STJLCATA, Walker and Jacob. Discovery Passage at station No. 7, a few specimens. 
 
 NODOSARIA (DENTALINA) PAUPERATA, d'Orbigny. Strait of Georgia at stations Nos. 2 and 4, 
 but in very small numbers. 
 
 FRONDICTJLARIA CANALICULATA, Reuss. 
 
 FIG. 1. Frondicularia canaliculata, Reuss. Drawn from a living specimen dredged in 
 the Strait of Georgia, and enlarged six diameters. 
 
 Verstein Bohm. Kreid, 1845, Pt. I. p. 31. PI. VIII. Figs. 20, 21. 
 
 Strait of Georgia, at station No. 3, one perfect living specimen and a fragment 
 of another, and at station No. 4, eight perfect and living specimens. This species, 
 for the identification of which the writer is indebted to Mr. H. B. Brady, has long 
 been known as a fossil of the Chalk Formation of Bohemia and England, but the 
 specimens dredged by Dr. Dawson are the first that have been discovered in a 
 living state. 
 
 CRISTELLARIA CULTRATA, Montfort. Strait of Georgia at station No. 4, four specimens of a 
 large variety in which the sutures are prominently overlaid by raised lines of 
 shelly deposit. 
 
 CRISTELLARIA CULTRATA, var. With the terminal end straightened and the shape like 
 that of C. reniformis and C. compressa, but the sutures are strongly arched. A single 
 specimen from the same station as the preceding. 
 
 POLYMORPHINA LACTEA, Walker and Jacob. Discovery Passage at station No. 7, one 
 specimen. 
 
 POLYMORPHINA COMPRESSA, d'Orbigny. Strait of Georgia at station No. 4, Queen Charlotte 
 Sound at stations Nos. 13 and 17, and Quatsino Sound at station No. 20, not 
 uncommon. Some of the specimens have as many as twelve segments, and the 
 sutures are not excavated. 
 
FI?OM THE COAST OP BRITISH COLUMBIA. 115 
 
 DISCORBINA PAIUSIENSIS, ttOrbigny. Discovery Passage at station No. 7, and Queen 
 Charlotte Sound at stations Nos. 14 and 17, not uncommon. Double specimens, in 
 which the bases of two shells have grown together, or specimens which have been 
 double, but which have been broken apart by some cause unknown, are more 
 frequent than normal and single examples. In the ninth volume of the Zoology 
 of the "Challenger" Expedition (p. 649) Mr. Brady says "it is probable that the 
 phenomenon is to be accounted for in the same way in all cases, that it is brought 
 about by the extension of a lobe of sarcode from the mouth of the parent test, the 
 subsequent division of the nucleus, and the continued growth of the new 
 individual withoiat separation from the parent, a very similar process to that 
 minutely watched by Gruber in a species of Euglypha. " 
 
 TRTNCATAL.INA LOBATULA, Walker and Jacob. Abundant, living and attached to shells, 
 stones, etc., at most of the stations at which the dredge was used. Dead and 
 detached specimens are frequent also in sand, etc., from stations Nos. 2, 7 and 17. 
 
 Pui/viNULitsA KARSTENI, Reuss. Discovery Passage at station No. 7, four specimens, and 
 Johnstone Strait at station No. 9, one specimen. 
 
 ROTALIA BECCARII, L. Discovery Passage at station No. 7, Queen Charlotte Sound at 
 station No. 14 and Quatsino Sound at station No. 20, a few examples at each. 
 
 NOMONINA SCAPHA, Fichtel and Moll. Johnstone Strait at station No. 9, and Queen 
 Charlotte Sound at station No. 17, apparently not very common. 
 
 POLYSTOMKLLA CRISPA, L. Queen Charlotte Sound at stations Nos. 14 and 17, and 
 Quatsino Sound at station No. 9, not uncommon. 
 
 POLYSTOMELIA STRIATOPUNCTATA, Fichtel and Moll. Johnstone Strait at station No. 9, nine 
 specimens. Two specimens were also noted in sand dredged at a depth of two 
 fathoms in Comox Harbour, Vancouver Island. 
 
 HYDBOZOA. 
 ALLOPORA VENUSTA, Verrill. Queen Charlotte Sound at station No. 15, several specimens. 
 
 ANTHOZOA. 
 
 PARACYATHUS CALTHA, Verrill. Strait of Georgia at station No. 5, one specimen, and 
 station No. 6, four specimens. 
 
 BALANOPHYLLIA ELEGANS, Verrill. Strait of Georgia at station No. 5, one specimen, and 
 station No. 6, two specimens. Discovery passage at station No. 7, four specimens. 
 
 OPHIUROIDEA. 
 
 OPHIOOLYPHA LUTKENI, Lyman. Discovery Passage at station No. 7, a few specimens, 
 and Queen Charlotte Sound at station No. 17, abundant. 
 
116 WHITEAVES ON MARINE INVERTEBRATA, ETC., 
 
 ASTEROIDEA. 
 
 ASTERIAS OCHRACEA, Brandt. Low water, Malaspina Inlet, one small specimen. 
 
 ASTERIAS CONFERTA, Stimpson. Low water, Malapina Inlet, five fine specimens. Discovery 
 Passage, at low water, one specimen. 
 
 ASTERIAS TROSCHELI, Stimpson. Several specimens of an Asterias with five long slender 
 rays and a very small disk, which are probably referable to this species, were 
 collected by Dr. Dawson at low water at the northern end of the Strait of Georgia, 
 at the entrance to Malaspina Inlet, at Kedonda Island (to the north-east of Cortez 
 Island) and in Discovery Passage. The smaller specimens from these localities 
 agree very well with Stimpson's description of A. Troscheli; but the larger ones, 
 which attain to a maximum diameter of rather more than a foot, and which are not 
 very well preserved, do not shew very clearly the peculiar pentagon formed by 
 clusters of spines in the centre of the upper surface of the disk, nor the marked 
 disparity in size between the larger and smaller dorsal spines, that are said to be 
 characteristic of the species. These larger specimens are precisely similar to a star- 
 fish collected by Mr. James Richardson in 18*74, at low water, near Victoria, 
 Vancouver Island, which was doubtfully and perhaps incorrectly referred to the 
 A. epichlora of Brandt in the " Canadian Naturalist " of December, 18*78, but both 
 they and it are quite different to the specimens from the Queen Charlotte Islands 
 which were called A. ejrichlora, but with a query, by the writer, on Prof. Verrill's 
 authority, in an appendix to Dr. Dawson's report on those islands. 1 Since that 
 appendix was written, however, two very typical and well preserved examples of 
 A. Troscheli have been detected among Dr. Dawson's collections from the Queen 
 Charlotte Islands. 
 
 ASTERIAS HEXACTIS, Stimpson. Taken rather sparingly, living, at low tide in Seymour 
 Narrows, Discovery Passage, Johnstone Strait and Queen Charlotte Sound. A few 
 badly preserved and small specimens of a six-rayed star-fish, which is also 
 probably A. hexactis, were dredged at station No. 14. 
 
 PYCNOPODIA HELIANTHOIDEA, Brandt. (Sp.) Hernando Island, Strait of Georgia, at low 
 water, one specimen. 
 
 SOLASTER STIMPSONI, Verrill. Low water at Port Neville, on the mainland of British 
 Columbia and on the north side of Johustone Strait, several. Twelve specimens of 
 a Solaster, which seems to be only a variety of this species, were dredged in Queen 
 Charlotte Sound at station No. 14. These differ from the type of S. Stimpsoni prin- 
 cipally in the unusually large size of the disc and in the shortness of the rays, 
 which latter are uniformly ten in number. The spines at the angles near the 
 mouth, also, are apparently more numerous. 
 
 SOLASTER DAWSONI, Veirill. Beach at Powell Island, Strait of Georgia ; one adult example. 
 Entrance to Malaspiua Inlet, at low water ; one small specimen. Low water at 
 Johnstone Strait and in the Goletas Channel ; abundant.

FROM THE COAST OF BRITISH COLUMBIA. 117 
 
 CRIBRELLA L^EVIUSCULA, Stimpson. Low water at the entrance to Maluspina Inlet, in the 
 Goletas Channel, and on the coast between Nahwitti village and Quatsiuo Sound, 
 several from each of these localities. 
 
 DERMASTKR IMHRICATUS, Perrier. (=Asteropsis imbrimta, Grube.) Beach at Hernando Island, 
 two large specimens ; low water at the entrance to Malaspiua Inlet, one specimen ; 
 and Johustone Strait, one specimen. 
 
 MED AS TK i; .KIJTALIS, Slimjtson. Low water at the north end of Malcolm Island, Queen 
 Charlotte Sound, one fine specimen. 
 
 AM iiiuioMrM ORANULARE, O. F. Mutter. One beautiful living example of this rare spe- 
 cies, which is now for the first time recorded as occurring in the North Pacific, was 
 dredged in forty fathoms in the Strait of Georgia, off the mouth of the Qualicum 
 River. It is almost precisely similar to a specimen of the same species taken some 
 years ago off" Halifax, Nova Scotia, and now in the Redpath Museum in Montreal. 
 For the loan of the latter, for comparison, the writer is indebted to Sir William 
 Dawson. 
 
 l 
 
 ECHINOIDEA. 
 
 DENDRASTER EXCENTRICUS, Valenciennes. (Sp.) Beach at Mary Island, Strait of Georgia, 
 several dead and bleached specimens denuded of their spines. Low water at 
 Savary Island, in the same strait, alive and numerous. 
 
 LOXECHINUS PURPURATTJS, Stimpson. (Sp.) Common almost everywhere along the coast. 
 STKONGYLOCENTROTUS DROBACHIENSIS, Mull. With the preceding, and equally common. 
 
 ^ 
 
 HOLOTHUROIDEA. 
 
 PENTACTA FRONDOSA, Gunner. Two specimens of a very large Holothurian which appear 
 to belong to this species, though they have not been examined microscopically, 
 were dredged in Queen Charlotte Sound; one at station No. 11 and one at station 
 No. 12. 
 
 A number of small Holothurians, which have yet to be studied, were dredged in 
 Queen Charlotte Sound, at station No. 14. 
 
 TUNICATA. 
 
 CYNTHIA (HALOCYNTHIA) PYRIFORMIS, Rallike. Queen Charlotte Sound at station No. 18, 
 two living specimens. 
 
 BRACHIOPODA. 
 
 RHYNCHONELLA PSITTACEA, L. Discovery Passage at station No. 7, one fresh ventral valve. 
 Low tide, Johnstone Strait, a few small but living specimen- 
 
118 WHITE AVES ON MARINE INVEETEBRATA, ETC., 
 
 /TEREBRATULINA UNGUICULA, Carpenter. Strait of Georgia, near Comox, in forty fathoms ; 
 one small living specimen. Discovery Passage at station No. 7, a large ventral 
 valve. Low tide, Johnstoue Strait, one small living specimen; and Johnstone 
 Strait at station No. 10, two small living specimens. 
 
 The Terebratula unguicula of the late Dr. P. P. Carpenter was regarded as merely 
 a local variety of the European T. caput-serpentis by the late Dr. Thomas Davidson. 
 A series of adult and perfect examples of T. unguicula, dredged by Mr. James Rich- 
 ardson in 18*76 in the Strait of Georgia, was sent by the writer to Dr. Davidson, for 
 examination, in the fall of 1884. In a letter dated November 29, 1884, Dr. Davidson 
 writes : " The specimens named TerebratuHna unguicula are only a variety of T. caput- 
 swpentis. I will describe it in my monograph " (one on recent brachiopoda, then in 
 course of preparation) " as Terebratttlina caput-serpentis, var. unguicula, Carpenter. I 
 compared all your Vancouver examples very minutely with a number of European 
 specimens of Liune's species, and feel confident that T. unguicula is not a distinct 
 species." 
 
 . LAQUETJS CALIFORNICTJS. Koch. Discovery Passage at station No. 7, one dead but perfect 
 shell and a large dorsal valve. Johnstone Strait at station No. 10, five living 
 adult specimens and several young. Race Passage, Johnstone Strait, two small 
 but living specimens. 
 
 ^TEREBRATELLA TRANSVERSA, Sowerby. (=T. caurina, Gould.) Low tide, Strait of Georgia, 
 many small but living and strongly ribbed specimens. Entrance to Malaspina 
 Inlet, at low water, one living specimen. Discovery Passage at station No. 7, 
 three small living specimens and one dead shell. Johustone Strait at station 
 No. 10, two adult living shells and one small one. Queen Charlotte Sound 
 at station No. 12, one small living shell, and at station No. 18, five small, living 
 specimens. 
 
 At these localities, some of the specimens have strong, radiating ribs, while 
 others are almost entirely smooth, but there are intermediate gradations between 
 the ribbed and the smooth forms, which latter is the one represented by Sowerby 
 in the "Thesaurus Conchyliorum," as the type of T. transversa. 
 
 LAMELLIBRANCHIATA. 
 
 v PLAOUNANOMIA MACROSCHISMA, Deshayes. Entrance to Malaspiua Inlet, at low water ; 
 three small, living specimens attached to Ostrea lurida. Strait of Georgia at station 
 No. 2, two rather small, living specimens. Quatsino Sound, Vancouver Island, one 
 large and two small living shells. 
 
 / OSTREA LTJRIDA, Carpenter. Entrance to Malaspina Inlet, at low tide, two living speci- 
 mens. A number of good specimens of this species, which were said to have been 
 taken near Comox, were purchased in Victoria, Vancouver Island. Bradley Lagoon, 
 Blunden Harbour, Queen Charlotte Sound, on the mainland side, abundant. This 
 last is the most northerly locality yet recorded for oysters on the coast of British 
 Columbia. 
 
KHOiL TIII-: COAST OK BHITISH COLUMBIA. 119 
 
 HiNNlTES (HOANTEUS, Gnii/. Entrance to Maluspina Inlet, associated with the two pre- 
 ceding species, one rather small and dead specimen. Low water at Fort Rupert, 
 on the north-east .-oast of Vancouver Island, one adult living shell, and a similar 
 one from the entrance to Quatsiuo Sound, also at low water. 
 
 I'KCTEN AI-ASKKNSIS, Dnll. Quatsiuo Sound at station No. 20, one small but living 
 specimen. This species, which has hitherto been recorded as occurring only at 
 " North Harbor, Unga Island," and " Port Etches, Chugach Gulf," is new to the 
 Vancouver region. 
 
 I'r.cTKX ii VST ATI'S, Soiverby. (=P. Jwrimnt. Grid.) Strait of Georgia at station No. 6, one 
 living, adult shell, with the exterior of both valves nearly covered by an encrusting 
 sponge. Goletas Channel, one small but living shell. Quatsino Sound at station 
 No. 1!'. live adult, living and brightly coloured specimens of the typical form of 
 the species, in which the principal ribs are few, distant, and ornamented with erect 
 vaulted scales. 
 
 PECTEN ITASTATUS, var. HINDSII, Carpenter. Strait of Georgia at station No. 5, two rather 
 small, living shells and a few fragments. Discovery Passage at station No. 7, two 
 small, living shells and three single valves. Johnstone Strait at station No. 10, 
 four medium sized, living specimens (one passing distinctly into the var. rubidus) 
 and a few very small ones. Queen Charlotte Sound at station No. 14, one living 
 specimen ; at station No. 17, three small living shells ; and at station No. 18, one 
 small, living shell. Quatsino Sound at stations No. 19 and 20, a few living speci- 
 mens of various sizes. 
 
 LIMATULA SL'iui'RicuLATA,' Monlugu. Johnstone Strait at station No. 10, and Queen 
 Charlotte Sound at station No. 14, a single living specimen from each of these 
 localities. Not included in the Vancouver fauna in Dr. Carpenter's " Guide to the 
 Diagnosis of the Vancouver and Californian Shells," on pages 122-150 of his last 
 report on " The Mollusks of Western North America," published in 1872 by the 
 Smithsonian Institution. 
 
 YOLDIA LANCEOLATA, /. Smverby. Quatsino Sound at station No. 20, a few living specimens. 
 
 / YOLDIA (PORTLANDIA) THRACI^EFORMIS, Storer. From the same station as the last, two 
 small but living specimens. This species also is new to the Vancouver district. 
 
 / LEDA FOSSA ? Baird. Discovery Passage at station No. 7, one single and worn valve. 
 ^LEDA MINTJTA, O. Fabricius. Quatsino Sound at station No. 19, two living specimens. 
 
 LEDA ACUTA, Conrad. (=L. cuneata, Sowerby.) Same locality and station as the preceding ; 
 ten perfect specimens (most of which were living) and three single valves. 
 
 A single valve of a Leda from Houston Stewart Channel, Queen Charlotte 
 Islands, which was referred by the writer to the Leda ccclala of Hinds (on p. 200 B 
 of the Report of Progress of the Geological Survey for 1878-79) is almost certainly 
 referable to L. acuta, Conrad, of which, according to Dall, L. cuneata, Sowerby, is a 
 synonym. On the other hand, in the sixth volume of the " American Journal of 
 Conchology," (p. 55) Dr. J. G. Cooper suggests that Leda cuneata may be only a 
 variety of L. calata. 
 
12O WHITEAVES ON MARINE INVERTEBRATA, ETC.,

 tion No. 7, and Queen Charlotte Sound, at stations Nos. 14 and 16, a few immature 
 living specimens at each of these localities. 
 
 . MODIOLA MODIOLTJS, L. Johnstone Strait at station No. 10, six half-grown, living shells, 
 with a simply bearded epidermis. Queen Charlotte Sound at stations Nos. 11, 12, 
 14, 16 and 18, a few living, but for the most part, very young specimens at each. 
 The species usually lives in the crevices of rocks, or between or on stones. 
 
 / MYTILUS EDULIS, L. A few specimens of the fry of this very common and ubiquitous 
 species occur in dredgings in the Strait of Georgia, at station No. 5.

 CRYPTODON SERIOATT-S, Carpenter : (Not " serricatus.") Quatsino Sound at station No. 20, 
 several small but living spe.-imens. In a letter to the writer, Mr. Ball says ' the 
 .specific name ol' this shell is misspelled in l>r. Carpenter's last report, but the 
 mistake was corrected by him in 
 
 / LuciN,v FILOSA, Stiiiipson. Quatsino Sound at station No. 19, one small but living shell; 
 and at station No. 20, a large and perfectly fresh single valve.

 men ; and Quatsino Sound at station No. 19, abundant, living. 
 
 Vi:\KKK'u;i>iA HOIJKALIS. Conrad. Living, but usually of small size, at the following 
 localities : Strait of Georgia at station No. 5, Johnstone Strait at station No. 10, 
 Queen Charlotte Sound at stations Nos. 12, 14, 15, 17 and 18; and Quatsino Sound 
 at station No. 19. A few dead valves of this shell were dredged at station No. 1, 
 in Discovery Passage. 
 
 ASTAKTK r.\ DATA? Gould, var. Strait of Georgia at station No. 5, two living and full- 
 grown specimens ; Discovery Passage at station No. 7, two living specimens and 
 several single valves, and Johustone Strait at station No. 10, one living and 
 unusually large specimen. 
 
 The shells from station No. 5 can scarcely be separated from examples of a 
 variety of A. undata dredged by the writer, in 1873, between Pictou Island and Cape 
 Bear, P.E.L ; while those from stations No. 7 and 10 are more transversely elon- 
 gated and more like A. elliptica in shape, but their ribs are fewer (some fourteen or 
 iil'ieen in number) and more prominent, and shew little if any tendency to become 
 obsolete near the ventral margin. A single dead and immature valve of an Astarte, 
 dredged by Dr. G. M. Dawsou off Metlakatla in 1878, and identified by the writer, 
 with doubt, as possibly the A. semixulmta of Leach, in the Report of Progress of the 
 Geological Survey of 1878-79 (p. 197 B) is certainly identical with the shells here 
 provisionally referred to A. unduta. 
 
 /ASTARTE ESQUIMALTI, Baird. Strait of Georgia at station No. 5, two living specimens ; 
 Discovery Passage at station No. 7, abundant, alive ; Johnstone Strait at station 
 No. 10, two living specimens ; and Queen Charlotte Sound at station No. 12, four

 and the two preceding species are eaten by the Indians, who call this the " small 
 round clam." 
 
 VVENUS KENNERLYI, Reeve. Discovery Passage at station No. Y, one full-grown living 
 specimen and a very small one ; also in Queen Charlotte Sound at station No. 12,

 shells from the Queen Charlotte Islands already referred to in this paper. 
 
 VARIEGATUS, Carpenter. Quatsino Sound at station No. 19, a fully grown living 
 specimen.

 one mm. in length and thirteen mm. in height, is from the locality last mentioned. 
 
 / SCHIZOTH^RUS NUTTALLI, Conrad. Common at low tide at many places along the coast 
 and used for food. The only localities from which specimens were brought are 
 Galiano Island in the Strait of Georgia, and Fort Kupert, Beaver Harbour, on the 
 north coast of Vancouver Island. 
 
 X MYA TRUNCATA, L. A few young specimens of this species were dredged in Discovery 
 Passage at station No. 8, in Johnstone Strait at station No. 10, in Queen Charlotte 
 Sound at station No. 12, and in Quatsino Sound at station No. 20. 
 
 SAXICAVA PHOLADIS, L. (=S. rugosa, Lamarck.) A few specimens of this common littoral 
 species were collected at low water at the entrance to Malaspiua Inlet, at Port 
 Neville, B. C., and Quatsiuo Sound. A living but immature specimen, also, was 
 dredged at station No. 20 in Quatsino Sound.

 Johnstone Strait, on the east side of Queen Charlotte Sound ; on the north and 
 north-west coast of Vancouver Island, from Nahwitti Bar to Quatsino Sound, and 
 in Quatsino Sound. 
 
 CADTJLUS ABERRANS. N. Sp. 
 
 FIG. 2. Cadvlus aberrans. Side view of an average specimen, enlarged three diameters. 
 
 Shell slender, moderately but distinctly curved, large and much elongated for 
 the genus, increasing very slowly but regularly in diameter, not distinctly (if at all) 
 swollen in advance of the middle, and very slightly and scarcely perceptibly con- 
 stricted immediately behind the aperture. Test extremely thin, surface polished, 
 very glossy and shining, smooth to the naked eye, but under a lens it is seen to be 
 marked with minute and transverse but somewhat oblique lines of growth. 
 
 Length of an average, full-sized example, 13.5 mm. ; greatest breadth of the 
 same near the anterior end, 1.3 mm. 
 
 Very abundant in Quatsino Sound at station No. 20. 
 
 This little shell, which is nevertheless of large size for the genus, looks not 
 unlike an immature Dentalium, and, at first sight, specimens of it might be easily 
 mistaken for half-grown examples of D. pretiosum, Nuttall, which the Indians say 
 occurs at the same locality. It may, however, be distinguished from any Denta- 
 lium by its thin test and highly polished outer surface, though the swelling of the 
 shell in advance of the middle and the constriction behind the aperture, which are 
 usually marked characters in the genus Cadulus, are reduced to a minimum in this 
 species, and in most specimens are quite imperceptible. 
 
 The writer has been informed by Mr. Ball that there are specimens of this shell 
 in the museum of the Smithsonian Institution at "Washington, which were collected 
 by Dr. J. G. Cooper at Catalina Island, California. 
 
 - MOPALIA CILIATA, Sowerby. (Sp.) More or less abundant, living, at low tide, in Discovery 
 Passage, Johnstone Strait, the Goletas Channel, and Quatsiuo Sound. One living 
 specimen was dredged in Queen Charlotte Sound at station No. 18. 
 
 , MOP ALIA LIGNOSA, Gould. Living, at low tide, on the north side of the Strait of Georgia, 
 in the Goletas Channel; and in Queen Charlotte and Quatsino Sounds. 
 
PROM THK COAST OP BRITISH COLUMBIA. 12S 
 
 / MOPALIA WOSSNESSENSKYI, Middendorf. Associated with the two preceding species, but 
 apparently very much ruivr than either. 
 
 IMPORCATA, Carpenter. (Sp.) Johustone Strait at station No. 10, one 
 small, living specimen, with the girdle partly overgrown by a hydroid. 
 
 CKYITOCIUTON STELLERI, Miildonhrf. Discovery Passage, between Vancouver and Cortez 
 Islands, in about one fathom of water, one living specimen. Low tide, Johustone 
 Si rait, two living specimens; and on Thurlow Island, east end of Johnstone Strait, 
 four living shells. Low iide, Beaver Harbour, Vancouver Island, one living 
 specimen. One living specimen, also, was dredged in Queen Charlotte Sound at 
 station No. 15. 
 
 Dr. Dawson states that this species is generally distributed on rocky ground 
 at and below low tide mark, but that it is nowhere very abundant. This and the 
 next-named species are cooked and eaten by Indians. 
 
 KATHERINA TUNICATA, Soiverby. On rocks at low water all over the coast, and in some 
 places very abundant. 
 
 LEI>TOCIIITON CANCELLATUS, Sowerby. Queen Charlotte Sound at station No. 12, eleven 
 small but living .specimens, four of which have been identified with this species 
 by Mr. "NV. H. Dall. Three specimens of a small, white Chiton, from station No. 14, 
 appear also to belong to this species. 
 
 LEPTOCHITON PUNCTATUS. N. Sp. 
 
 FIGS. 3 and 4.Lcptochiton j,iiiict<itu*. The figure on the left hand side represents the type 
 
 specimen enlarged three diameters, and that on the right one of the central 
 
 valves, enlarged eight diameters to shew the sculpture. 
 
 Shell small, elongated, rather strongly elevated, back distinctly augulated ; 
 colour, pale cream or nearly white, but with a few small patches of reddish-brown 
 on the girdle, and a narrow and non-continuous series of variously interrupted 
 and broken up yellowish-brown spots upon the median line of all the valves but 
 the anterior one. Girdle squamose, the scales closely imbricating, much broader 
 than high, and distinctly striated when viewed under an achromatic microscope 
 with a half-inch objective. Mucro central and tolerably distinct where not worn 
 oil'; anterior valve marked with faint but rather numerous radiating striae and 
 
126 WIIITEAVES ON MARINE 1NVERTEBBATA, ETC., 
 
 concentric lines of growth. Central areas of all the valves but the anterior one 
 regularly pitted, as viewed by an ordinary simple lens of moderate power, the 
 pitting being most distinct near the suture. These pits are the interstices between 
 longitudinal, lightly curved and convergent raised lines, and the curved raised 
 lines of growth. Lateral areas of the valves (exclusive of the anterior one) not so 
 distinctly pitted, but more or less marked with faint radiating striae, especially 
 those of the anterior portion of the shell ; those of the third to the seventh, both 
 inclusive, each bearing from four to six distant, isolated, prominent and rounded 
 tubercles on each side, three being usually placed on each of the lines which 
 separate the lateral from the central areas. 
 
 Length of the only specimen collected, about fourteen millimetres ; maximum 
 breadth of the same, six and a half. 
 
 Discovery Passage at station No. 7, one living specimen. 
 
 An interesting and beautiful little species, apparently well characterized by 
 the peculiarly punctate surface of the central area of the valves. 
 
 TONICELLA LINEATA, Wood. (Sp.) Frequent, living, at low water, on the north shore of 
 the Strait of Georgia, in Malaspina Inlet, Discovery Passage, Race Passage in 
 Johnstone Strait, Queen Charlotte Sound, and on the north and north-west coast 
 of Vancouver Island, from Nahwitti Bar to Quatsino Sound. Taken abundantly 
 from the stomach of a harlequin duck (Histrionicus torquatus) shot at Mittlenatch 
 Island, in the Strait of Georgia. Dredged also in Queen Charlotte Sound at station 
 No. 12. 
 
 / ISCHNOCHITON INTERSTINCTTJS, Gould. (Sp.) Low tide in Eace Passage Johnstone Strait, 
 and in Queen Charlotte Sound, but apparently not common. More abundant in 
 Discovery Passage at station No. 1, in Johnstone Strait at station No. 10, in Queen 
 Charlotte Sound at stations Nos. 12, 14, 15 and 16, and in Quatsino Sound at 
 station No. 20. 
 
 ISCHNOBADSIA TBIFIDA, Carpenter. (Sp.) Queen Charlotte Sound, one large, living 
 specimen. 
 
 LEPIDOPLEURTJS MERTENSII, Middendorf. (Sp.) Discovery Passage at station No. 7, two 
 living specimens; and Queen Charlotte Sound at station No. 15, one living 
 example.

 Strait. 
 
 (COLLISELLA) PELTA, Eschscholtz. Common and alive at low tide at the north end 
 of Texada Island, Strait of Georgia ; in Discovery Passage, between Seymour Nar- 
 rows and Elk Harbour ; in Johiistone Strait ; on the east side of Queen Charlotte 
 Sound ; and along the north and north-west coast of Vancouver Island, from Nah- 
 witti Bar to Quatsino Sound. Numerous but dead specimens were dredged in 
 Discovery Passage at station No. 7. 
 
 (COLLISELLA) PERSONA, EschscMtz. Low tide in Discovery Passage, between 
 Seymour Narrows and Elk Harbour, four adult, living specimens. 
 
FROM THE COAST OF BRITISH COLUMBIA. 127 
 
 MITRA, Eschsrholt'. Low tide at Malaspina Inlet in the Strait of Georgia, and 
 Queen Charlotte and Quatsino Sounds. Dredged also in Queen Charlotte Sound at 
 stations Nos. 12, 15 and 18, and at the entrance to Quatsino Inlet at station No. in 
 Moderately abundant near low water mark almost everywhere. 
 
 INSTABJUS, d'oi/lr/. Low tide on the north and north-west coast of Vancouver 
 Island, between Nahwitti Bar and Quatsino Sound ; three adult, but dead shells. 
 
 CRYPTOBKANCHIA CONCENTRICA, Miildendorf. (Lepeta cacoides, Carpenter.) Queen 
 ( 'harlotte Sound at station No. 17, one living specimen ; and Quatsino Sound at 
 station No. 20, several. 
 
 (iLYi'ins ASPERA, Eschscholtz. Common, living at low tide in Malaspina Inlet, Strait of 
 Georgia ; in .Tohnstoue and Broughtou Straits ; in the Goletas Channel, and on the 
 west coast of Vancouver Island, north of Quatsino Sound. 
 
 cucuLLATA, Gould. Low water at Race Passage, Johnstone Strait, one 
 largo, living specimen. Dredged also alive, but sparingly, in Discovery Passage 
 at station No. 7, in Queen Charlotte Sound at stations Nos. 12 and 17, and in 
 Quatsino Sound at station No. 20. 
 
 PUXCTURELLA OALEATA, Gould. Dredged living, but in very small numbers, in Discovery 
 Passage at station No. 7, in Johnstone Strait at station No. 10, in Queen Charlotte 
 Sound at stations Nos. 12, 15 and 18, and in Quatsino Sound at station No. 20. 
 Specimens sometimes occur which seem to be intermediate in their sculpture 
 between this and the preceding-species. 
 
 / HALIOTIS KAMTSCHATKANA, Jonas. Living at a little below low tide at Port Neville, on 
 the mainland of British Columbia, north of Johnstoue Strait ; at Beaver Harbour, 
 on the north-east coast of Vancouver Island ; in the Goletas Channel ; and at the 
 entrance to Quatsino Inlet. Dr. Dawson says that this species is most abundant in 
 exposed situations on the northern and outer coast of Vancouver Island, but that 
 it is rarely met with in the Strait of Georgia or other land-sheltered waters. 
 
 The animal, or foot of the animal, is eaten by the Indians, and dried for sale 
 to the Chinese, while the nacreous interior of its shell is" largely used by the 
 Indians for inlaying and other ornamental or decorative purposes. 
 
 ^ PACHYPOMA GIBBEEOSUM, Chemnitz. On rocks and kelp at a little below low-water mark 
 in Quatsino Sound ; abundant at some localities. 
 
 The thick, calcareous operculum of this shell is used for ornamental inlaying, 
 in wooden ware, by the Indians of the coast. 
 
 ^ LEPTOTHYRA SANGUINEA, L. (Sp.) Living, at low tide, in Johnstone and Broughton 
 Straits, in the Goletas Channel, and on the ea'st side of Queen Charlotte Sound. 
 Dredged, also, in Queen Charlotte Sound at station No 15, and in Quatsino Sound 
 at station No. 20. 
 
 Mr. Tryoii appears to be mistaken in supposing that the Califomian shells 
 which Dr. Carpenter referred to this species, have a " corneous " operculum and 
 
128 WHITEAVES ON MARINE INVERTEBRATA, ETC.. 
 
 arc different from the Turbo sanguineus of Linnaeus. 1 In a letter to the writer, 
 Mr. Ball says : " The west coast shell is the sanguineu, L. ; is not the type of 
 Collonia, Gray, which is African and umbilicated, and has a calcareous operculum. 
 It inhabits Japan, California, and the, .ZEgean Sea." The specimens collected by 
 Dr. Dawson certainly have a calcareous operculum. 
 
 /- CHLOROSTOMA FUNEBRALE, A. Adams. Collected abundantly, living, at or a little below 
 low tide level on the north and north-west coast of Vancouver Island, between 
 Nahwitti Bar and Quatsino Sound. Apparently confined to the north and west 
 coast ot the island. 
 
 CALLIOSTOMA COSTATUM, Martyn. Low tide in Johnstone aud Broughton Straits, in the 
 G-oletas Channel, and on the east side of Queen Charlotte Sound, common and 
 living. Dredged also, abundantly and alive, in Queen Charlotte Sound at station 
 No. 15. 
 
 yCALLTOSTOMA ANNULATUM, Martyn. Johnstone Strait at station No. 10, one small, living 
 specimen. A much scarcer species than the preceding one on the coasts of 
 Vancouver and the Queen Charlotte Islands. 
 
 xGriBBULA (PHORCus) PTJLLIGO, Marlyn. Abundant at and a little below low water mark, 
 in Johnstone and Broughton Straits, in the Goletas Channel, on the east side of 
 Queen Charlotte Sound, and on the northern and western coasts of Vancouver 
 Island ; often on fronds and stems of Macrocystis. 
 
 The specimens from Carpenter Bay, which were referred by the writer to the 
 Chlorostoma brunneum of Philippi, in a list of shells from the Queen Charlotte Islands, 
 published in the Eeport of Progress of the G-eological Survey of Canada for 1878-79 
 (p. 201 B), are forms of this species. The true Clilorostoma brunneum has not yet been 
 found north of California. 
 
 
 
 SOLARIELLA PERAMABILIS, Carpenter. Six fine living specimens of this rare shell were 
 dredged in Queen Charlotte Sound at station No. 17. The species had not pre- 
 viously been recorded as occurring north of California. Mr. W. H. Ball, who has 
 examined three of the specimens collected by Dr. Dawson, says that they are " ruder 
 and larger than those from the Santa Barbara Channel," and that the former " might 
 perhaps be regarded as a local variety of the species." Dr. Paul Fischer (" Manuel de 
 Conchyliologie," Paris, p. 826) says that Machccroplax of Friele (IS 1 ? 1 ?) is synonymous 
 with Solariella of Searles Wood (1842). 
 
 .MARGARITA CIDARIS, A. Adams. Johnstone Strait at station No. 10, two very young but 
 living shells. Queen Charlotte Sound at station No. 17, a fine series of eighteen 
 living specimens of all ages, several being adult, and the largest measuring fbrty 
 six millimetres in height (or length) by about thirty-two in maximum breadth- 
 Entrance to Quatsino Inlet at station No. 19, two half-grown and dead shells. 
 
 The only previou sly known specimen of "this very remarkable and unique 
 shell," as Dr. P. P. Carpenter calls it, was found at Neeah Bay, Washington Territory, 
 by Mr. J. Gr. Swan.

FfiQM THE COAST OF BRITISH COLUMBIA. 129 
 
 In one of the specimens collected by Dr. Dawson the columella has a greenish 
 iridescence not unlike that of some varieties of labradorite. 
 
 MARGARITA ITPILLA, Gould. Collected sparingly, alive, at low water mark in Beaver 
 Harbour (on the north-east coast of Vancouver Island), in the Goletas Channel, on 
 the east side of Queen Charlotte Sound, and at the entrance to Quatsino Sound. 
 Dredged also, in small numbers but living, in the Strait of Georgia at stations 
 Nos. 2, 5 and 6, in Discovery Bay at station No. 7, in Johnstone Strait at station 
 No. 10, in Queen Charlotte Sound at stations Nos. 12, 14, 16, 17 and 18, and in 
 Quatsino Sound, at station No. 20. 
 
 MARGARITA LIRULATA, Carpenter Discovery Passage at station No. 17, one very small 
 living specimen ; Queen Charlotte Sound, at station No. 12, about twenty adult 
 living specimens ; and Quatsino Sound at station No. 20, one living and full- 
 grown shell. 
 
 In the seventh volume of the " American Journal of Conchology," (pp. 128, 
 129) Mr. Dall expresses the opinion that Gibbula oplabilis, Cpr., G. parcipicta, Cpr., 
 G. funiadata, Cpr., G. sucrincla, Cpr., and perhaps G. lacunata, Cpr., as well as 
 Margarita tenuisculpla, Cpr., are all forms of the present " protean species." 
 
 MARGARITA HELICINA, Fabricius. Low tide in Johnstone Strait, three immature, living 
 specimens. Dredged also in Queen Charlotte Sound at stations Nos. 12 and 16, 
 one living, adult shell at each. 
 
 CREPIDTJLA DORSATA (Broderip), var. LINOTJLATA, Gould. (=C. bilobata, Reeve.) Low tide 
 at the entrance to Malaspina Inlet, in the Strait of Georgia, and in Quatsino 
 Sound ; three or four living specimens at each locality. Dredged also very 
 sparingly, but alive, in the Strait of Georgia at station No. 2, and in Johnstone 
 Strait at station No. 10. 
 
 CREPIDULA AUUNCA, Sowerby. Entrance to Quatsino Sound at low water, and on the west 
 coast of Vancouver Island, north of Quatsino Sound, also at low water, a single 
 specimen at each of these localities. 
 
 CHEPIDUIA NAVICELLOIDES, Nuttall. Dredged in very small numbers, but alive, in Queen 
 Charlotte Sound at stations Nos. 12, 14 and 16. Mr. Tryon thinks that this shell is 
 only a local variety of C. Lessoni, Broderip. 
 
 GALERUS FASTIGIATUS, Gould. Not uncommon and living, in Discovery Passage at station 
 No. 7, in Johnstone Strait at station No. 10, and in Queen Charlotte Sound at 
 stations Nos. 12, 14 and 16. The Galerus from the Queen Charlotte Islands, which 
 was named G. contortus, Gould, b / the writer, in the paper already referred to, is 
 almost certainly G. fastigiatus, but this latter name, Mr. Tryon says, is a synonym 
 of G. mamiUaris, Broderip. 
 
 BIVONIA COMPACTA, Carpenter. Discovery Passage at station No. 7, a living specimen on 
 Trophon tenuisculptus, Carpenter ; and in Quatsino Sound at station No. 19, one 
 specimen, also living, attached to the under valve of a typical example of Pecten 
 hastatits.

13O WHITEAVES ON MARINE INVEETEBEATA, ETC., 
 
 MESALIA RETICULATA, Mighcls. (=Turritella lactea, Moller, and Mesalia ladeola, Carpenter.) 
 Dredged rather abundantly, living, in the Strait of Georgia at station No. 5, in 
 Discovery Passage at station No. 8, in Johnstone Strait at station No. 10, in 
 Queen Charlotte Sound at stations Nos. 12, 13, 14 and 1*7, and in Quatsino Sound 
 at station No. 20. 
 
 >BiTTlUM FILOSUM, Gould. Common, living, at low tide, in Malaspina Inlet, Strait of 
 Georgia ; in Discovery Passage, between Seymour Narrows and Elk Harbour ; in 
 Johnstone Strait, the Goletas Channel, and Queen Charlotte and Quatsino Sounds. 
 
 BITTIUM MUNITUM. (= Cerithiopsis munita, Carpenter.) Queen Charlotte Sound at station 
 No. 12, ten fine and mostly living specimens. The writer is indebted to Mr. "W. 
 H. Dall for the suggestion that this shell is probably a Bittium rather than a 
 Cerithiopsis, and that the Cerithiopsis columna of Dr. Carpenter is only an abnormal 
 form of it. 
 
 / LITTORINA SITCHANA, Philippi. A common littoral species throughout the district. A few 
 specimens of it were dredged in Discovery Passage, at station No. 7. The late Dr. 
 Jeffreys regarded this shell as only a local variety of the European L. rudis. 
 
 / LITTORINA SCUTULATA, Gould. With the preceding species, but apparently not quite so 
 common. 
 
 LACUNA SOLIDULA, Loven. (=L. carinata, Gould.) A few living specimens were taken at 
 or near low water in Alert Bay, B. C., and it was dredged living, but in very small 
 numbers, in Discovery Passage at station No. 8, and in Queen Charlotte Sound at 
 stations Nos. 12 and 15. Dr. Jeffreys was of the opinion that this shell is a variety 
 of L. divaricata, Fabricius (=L. vincta, Montagu), of northern Europe. 
 
 JBARLEEIA SUBTENUIS, Carpenter. Queen Charlotte Sound at station No. 12, one living 
 specimen. 
 
 J3UROULA PERVERSA, Gabb. Queen Charlotte Sound at station No. 16, one large, living 
 specimen, an inch and three-quarters in length, and another small but living shell ; 
 and station No. 17, an immature but living specimen. 
 
 This large and remarkable species, which is invariably sinistral, was previously 
 dredged alive by Mr. James Richardson in from thirty to seventy fathoms in the 
 Strait of Georgia. In the young state the test is nearly smooth and covered by a 
 very pale, greenish-grey epidermis, and the body whorl is encircled by two spiral 
 bands of a faint reddish-brown tint, one next to the suture and the other a little 
 below the middle. 
 
 x BELA FIDICULA, Gould. Johnstone Strait at station No. 10, four specimens ; Queen 
 Charlotte Sound at stations Nos. 14 and 16, one living specimen at the first, and 
 two full-grown, living shells at the second. 
 
 ' BELA TABULATA. (=Mangelia tabulata, Carpenter.) Queen Charlotte Sound at station 
 No. 16, two specimens. Perhaps only a variety of the last named species. 
 
 VIOLACEA, Mighels, var. (Teste Dall.) Queen Charlotte Sound at station No. 14, one 
 living specimen. 
 
FROM THE COAST OF BRITISH COLUMBIA. 131 
 
 /TuRBONiLLA VANCOUVERENSis. ( Cliemnitzia Vancouverensis, Baird.) Discovery Passage 
 at station No. 7, one living shell ; Johnstone Strait at station No. 10, one living 
 shell ; Queen Charlotte Sound at station No. 13, eight living examples of a white- 
 shelled variety of this species. 
 
 ODOSTOMIA SITKENSIS, Dall. Strait of Georgia at station No. 2, one living and full-grown 
 specimen. 
 
 .EULIMA POLITA, L. Living and frequent in the Strait of Georgia at stations Nos. 5 and 
 'I, in Discovery Passage at stations No. 7 and 8, in Johustoue Strait at station No. 
 10, in Quern Charlotte Sound at stations Nos. 14, 15 and 1*7, and in Quatsino 
 Sound at station No. 20. 
 
 About fifty living specimens of this shell were dredged by Dr. Dawson, and 
 the only observable difference between them and authentic English examples of 
 E. polita is one of size, the former attaining frequently to a length of thirteen milli- 
 metres, while the latter are sometimes as much as sixteen mm. long. Smaller 
 specimens of the same shell were dredged by Mr. Richardson in the Strait of 
 Georgia in 1875, and these were referred by the writer to the E. micans of Car- 
 penter, in " Canadian Naturalist," Vol. VIII, N. S. ; but Dr. Carpenter himself 
 regarded E. micans as " perhaps a smaller variety of the European E. polita." 
 
 ,- EULIMA INCURVA, Renieri (=.. distorta, auct.) With the above, but not nearly so common, 
 at stations Nos. 6, 10 and 14. Two living specimens were also taken at low tide in 
 Discovery Passage, between Seymour Narrows and Elk Harbour, and one at low 
 tide in the Goletas Channel. 
 
 y SCALARIA INDIANORUM, Carpenter. One fine, living adult specimen of this species, measur- 
 ing nearly an inch and a half in length, was dredged in Discovery Passage at 
 station No. 7. 
 
 , CANCELLARIA CIRCUMCINCTA, Dall. Johnstone Strait at station No, 10, one living and 
 adult specimen; Queen Charlotte Sound at station No. 12, a series of about twenty 
 living specimens, and at station No. 13, one full-grown living shell. 
 
 ADMETE VIRIDULA, Fabridus. Queen Charlotte Sound at stations Nos. 12 (three living 
 specimens), 1*7 (two living specimens), and 18 (one living specimen). Most of 
 these belong to the short-spired variety of the species, to which Verkruzen has 
 given the name undatocostata. 
 
 TRICHOTROPIS CANCELLATA, Hinds. Dredged more or less abundantly, alive, in the Strait 
 of Georgia at station No. 5, in Discovery Passage at station No. 7, in Johnstone 
 Strait at station No. 10, and in Queen Charlotte Sound at stations Nos. 12, 13, 
 15, 16, 17 and 18. Taken living also, in some numbers, at low water in Johnstone 
 Strait and the Goletas Channel. 
 
 / VELUTINA I^EVIQATA, L. Discovery Passage at station No. 8, one living specimen. 
 
 /NATICA CLAUSA, Broderip and Sowerby. Taken sparingly, but alive and in some cases of 
 considerable size, at low water, on the north shore of the Strait of Georgia ; in 
 
132 WHITEAVES ON MARINE 1NVERTEBRATA, ETC., 
 
 Johustone Strait ; at Beaver Harbour, Vancouver Island ; on the east side of Queen 
 Charlotte Sound, and on the north and north-west coast of Vancouver Island 
 between Nahwitti Bar and Quatsino Sound. Dredged also, alive, but in small 
 numbers, in the Strait of Georgia at station No. 5, in Discovery Bay at station No. 
 7, and in Queen Charlotte Sound at stations Nos. 12 and 17. 
 
 LUNATIA LEWISII, Old. Low tide, entrance to Malaspina Inlet, one specimen. 
 
 , LUNATIA PALLIDA ? Broderip and Sowerby. Queen Charlotte Sound at station No. 17, two 
 dead and imperfect shells. 
 
 ^TRITON (PRIENE) OREGONENSIS, Redfield. Low tide in Johnstone and Broughton Straits, 
 in the G-oletas Channel, and on the east side of Queen Charlotte Sound, but appar- 
 ently not very common. Dredged, living and adult, but in very small numbers, 
 in Johnstone Strait at station No. 10, and in Queen Charlotte Sound at stations 
 Nos. 11 and 12. This shell is possibly only a local variety of the Triton cancellatus 
 of Lamarck, from South America. 
 
 /MARGINELLA (VOLUTELLA) PYRIFORMIS, Carpenter. Low tide in the Goletas Channel ; 
 dredged also in Queen Charlotte Sound at station No. 12, and in Quatsino Sound 
 at station No. 20. One adult, living shell of this diminutive species at each of 
 these stations. 
 
 yOLiVELLA BIPLIOATA, Sowerby. Abundant, living, on the west or outer coast of Vancouver 
 Island. 
 
 OLIVELLA B^mcA, Carpenter. Strait of Georgia at stations Nos. 2 (frequent) and 5 (very 
 abundant), also in Discovery Passage at station No. 7, and in Queen Charlotte 
 Sound at station No. 16. Living, and apparently not uncommon, at each. 
 
 / CHRYSODOMUS LIRATUS, Martyn. Queen Charlotte Sound, at station No. 12, two living 
 but very young specimens, with the mammillated apex beautifully preserved ; at 
 station No. 16, one half-grown and dead specimen ; and at station No. 17, two fine 
 adult specimens (one living), with a short spire to the shell and an unusually 
 inflated or globose body whorl. 
 
 / CHRYSODOMUS DIRUS, Reeve. (Sp.) Abundant, living, at low water at the entrance to 
 Malaspina Inlet and on the north shore of the Strait of Georgia ; in Discovery Pas- 
 sage, between Seymour Narrows and Elk Harbour ; in Johnstone and Broughton 
 Straits ; in the Goletas Channel, and on the east side of Queen Charlotte Sound. 
 Dredged, but in small numbers, in Discovery Passage, at station No. 7. The generic 
 position of this species is uncertain, as the animal has not yet been described. 
 The shell does not look like that of a Chrysodomus or Sipho. Tryon places it in 
 the genus Euthria, but that course is not free from objections. 
 
 SIPHON VERKRITZENI, Kobelt. Queen Charlotte Sound at station No. 17, associated with 
 Neptunea lirata and other rare species ; one large, dead shell, but in excellent condi- 
 tion. Mr. Dall, to whom the writer is indebted for the identification of this 
 specimen, writes that it had previously been found in Norway and in Behring 
 Sea and Strait, but that the present is the most southerly locality yet reported for it. 
 
FROM THE COAST OP BRITISH COLUMBIA. 133 
 
 BUCCINUM POLARE (Gray), var. COMPACTUM, Da//. At the same station as the species last 
 mentioned ; one adul^but dead shell, in good condition. This species was collected 
 by Mr. James Ui< hardsou, at low water, near Victoria, Vancouver Island, in 18*75. 
 
 /NASSA (TiMTiA) MKNDICA, Gould. Strait of Georgia at station No. 5, alive and plentiful; 
 Johnstone Strait at station No. 10, one living specimen ; Queen Charlotte Sound 
 at station No. 12, several living shells ; and Quatsiuo Sound at station No. 20, ten 
 living specimens. 
 
 / ASTYRIS CABINATA (Hinds), var. HINDSII. (=Columbella Hindsii, Reeve.) Low tide in the 
 Goletas Channel, one living specimen. In this species the nucleus of the oper- 
 culum is said to be subcentral, or " somewhat more within the margin " than it is 
 in that of Nitidella Govldii. 
 
 x NITIDELLA GOULDII, Carpenter. Strait of Georgia at station No. 2, two living specimens, 
 and at station No. 5, abundant and living ; Quatsino Sound at station No. 19, three 
 living specimens. 
 
 This shell has been separated from the preceding species, both generically 
 and specifically, mainly upon minute differences in the opercula, the nucleus of the 
 operculum of N. Gouldii being stated to be nearly marginal. Morch, Ball and 
 Fischer, however, assert that in the Columbellidse the operculum is so variable 
 that it does not afford a good character for the discrimination of genera or species, 
 and Tryou, in his "Manual of Couchology," places N. Gouldii among the synonyms 
 of Columbella carinata. 
 
 /AMPHISSA COKKUGATA, Reeve. Common, living, at low tide, at the entrance to Malaspina 
 Inlet ; in llace Passage and other localities in Johnstone Strait ; in the Goletas 
 Channel, and in Queen Charlotte and Quatsiuo Sounds. Dredged also, alive and in 
 some numbers, in the Strait of Georgia at station No. 5, and in Queen Charlotte 
 Sound at stations Nos. 15, 16, 17 and 18. 
 
 , PUEPTJBA CEISPATA, Chemnitz. (=P. lactuca, Eschscholtz.) Extremely abundant and very 
 variable in size, shape, sculpture and colour, living at or near low water mark, on 
 the north shore of the Strait of Georgia, in Discovery Passage, in Johnstone and 
 Broughton Straits, in the Goletas Channel, on the east side of Queen Charlotte 
 Sound, and at the entrance to Quatsiuo Sound. Dredged also abundantly, alive, 
 in Discovery Passage at station No. 7, and in very small numbers in Johnstone 
 Strait at station No. 10, and in Queen Charlotte Sound at station No. 16. 
 
 PURPURA LIMA, Maityn. (=P. canalicutata, Duclos.) At low water throughout the district, 
 associated with the preceding, of which Von Martens and others regard it as only 
 a local variety. It did not, however, occur at any of the stations where the dredge 
 was used. 
 
 /PURPURA SAXICOLA, Valenciennes. Queen Charlotte Sound, at low tide, five adult, living 
 shells of a variety in which the interior of the aperture and part of the columella 
 is stained dark brown, while the former is margined exteriorly by a baud of pale 
 straw colour. Von Martens and other writers regard this shell as a mere variety 
 of P. lima, Martyu. 
 
134 WHITEAVES ON MAEINB INVERTEBRATA, ETC., 
 
 ,OciNEBRA LURIDA, Middendorf. Low tide in Johnstons Strait, one living, adult specimen ; 
 Queen Charlotte Sound at station No. 13, an immature^and dead shell. 
 
 OCINEBRA INTERFOSSA, Carpenter. Living, at low tide, but by no means common, in 
 .Tohnstone Strait and the Goletas Channel ; on the east and north west coast of 
 Vancouver Island, from Nahwitti Bar to Quatsino Sound, and at the entrance to 
 Quatsiuo Sound. One adult, living specimen was dredged at station No. 20. 
 
 ,CEROSTOMA FOLIATUM, Gmelin. Fine and frequent, living, at low tide, at Twin Island and 
 the entrance to Malaspina Inlet, in the Strait of G-eorgia ; in Johnstone and Brough- 
 ton, Straits ; in the Goletas Channel, and on the east side of Queen Charlotte Sound. 
 Dredged also, living and adult, in Discovery Passage at station No. *7. 
 
 TROPHON ORPHEUS, Gould. (=T. Stuarti, E. A. Smith.) Queen Charlotte Sound, at station 
 No. 14, an immature, living shell, nearly an inch and a half long, with the varices 
 prolonged behind into semitubular or deeply grooved, long, spiny frills, which 
 curve lightly backward ; at station No. 16, a living, adult shell, fully two inches 
 long ; and at station No. 18, a beautifully preserved living specimen, an inch and 
 a quarter in length, with the spinose frills prolonged to an unusual length behind. 
 
 /TROPHON CLATHRATUS, L. (=T. multicostatus, Eschscholtz.) Low water in Johnstone 
 Strait, one adult, living specimen. A similar, but slightly larger one was dredged 
 in Queen Charlotte Sound at station No. 12, and another at station No. 16. 
 
 /TROPHON TENTJISCTJLPTTTS, Carpenter. (=T. subserratus, Sowerby.) Not uncommon, alive, 
 at low tide, on the north side of the Strait of G-eorgia, in Seymour Narrows, and in 
 the Goletas Channel. A few living specimens, also, were dredged in Discovery 
 Passage at station No. I 7, in Johustoue Strait at station No. 10, in Queen Charlotte 
 Sound at stations Nos. 12, 16, 17 and 18, and in Quatsiuo Sound at station No. 19. 
 The largest specimens collected are a little more than an inch and a half in 
 length. "When examined with an ordinary simple lens, the whole surface of the 
 shell of this species is seen to be almost covered by densely-crowded, minute, 
 crenate and squamose raised lines of growth, which cross the spiral grooves and 
 ridges and are superimposed upon the varices. The types of T. tenuisculptus are 
 from the Pleistocene deposits at San Diego, but the shell is by no means uncommon 
 in a living state on the coasts of Vancouver and the Queen Charlotte Islands. 
 
 CEPHALOPODA.

 OMMASTREPHES SAGITTATUS, Lamarck. (Sp.) Three specimens of a squid, which corre- 
 spond very well with Tryon's description and figures of this species in the first 
 volume of his "Manual of Conchology," were collected at low water in Victoria 
 Harbour, Vancouver Island. 
 
 The following is a supplementary list of fresh-water and land shells, fishes (marine), 
 batrachians, ophidia, birds and mammals collected by Dr. Dawson and Mr. Dowling in the 
 same district and season : 
 
FEOM THE COAST OF BEITISH COLUMBIA. 135 
 
 FRESH-WATER SHELLS.

 mainland side, four small specimens. 
 
 LAND SHELLS. 
 
 'SELENITES VANCOUVERENSIS. (=Hdix Vancouverensis, Lea.) Harbledown and Fender 
 Islands, in Johustoue Strait ; and Malcolm Island, in Broughton Strait ; a few 
 living examples at each of these localities. Quatsino Sound, one dead and bleached 
 shell. 
 
 /ARIOLIMAX COLUMBIANUS? Gould. Malcolm Island, Broughton Strait, three specimens 
 in alcohol. These have not been dissected, and therefore may possibly be 
 A. Californicus, Cooper.

 Cove, Broughton Strait, one alive and one dead. 
 
 FISHES. 
 
 MERLUCIUS PRODUCTUS, Ayres. Merluccio. Off Gabriola Island, in the Strait of Georgia. 
 In this fish the scales on the sides of the body, which have been described as very 
 small, are really comparatively large and measure six millimetres by four. They 
 are, however, very easily rubbed off. 
 
 GADUS PROXIMUS, Ayres. Pacific Tom Cod. Caught in Alert Bay, Cormorant Island, at 
 station No. 14. 
 
 LIPARIS PULCHELLA, Ayres. Taken by the dredge at a depth of thirty fathoms in Queen

 not so distinctly rufous on the back. 
 
 PHOCA VITULINA, L. Harbour, Hair, or Leopard Seal. One specimen of the North Pacific 
 variety of the Harbour Seal was shot in Broughton Strait. The species may be 
 readily distinguished from all the other earless seals of both coasts of North 
 America by the oblique implantation of its molars.
