In addition, the writer has examined the bats in the Ignited States National Museum, the American Museum of Natural History, and several private collec- tions, making a total of about 2,700 specimens of North American Venim'tilioiiitla: It is to be regretted that so few S(mth American bats are contained in the museums of the United States that no definite con- clusions can be reached concerning the relationships of several Mexican species to the forms occurring farther south. For this reason certain questions of nomenclature must for the prei^ent remain in a condition of uncertainty. It is also to be regretted that comparatively few well- pre|>ared skins are available for corai)aiison. Without goossible to determine the limits of individual variation in color, as conclusions of the most general kin«l only can be based on specimens that have been subjected to the action of alcohol.

Hats which have been kept in ahtohol tor a period of more than a few months become so altered in color that they furnish reliable char- acters of si/.e and form only. The rate and amount of <'han};c appear to vary with dilferent species as well as with the strenyth of the pre- servative tluid and the amount of eximsurc to light. 1 have seen two h>tH of specimens of one species collected at the same place and liol those in one bottle still retained essentially their normal (;olor, as jiroved by ('omi)arison with skins col- lected at the same time, while those in another bottle were so bleached as to show scarcely a semblance of their original appearance. While the details of the changes produced by alcohol are not known, it amy be said that a gradual bleaching aud ultimate entiie loss of color is the general rule, though as a preliminary step browns are often very noticeably reddened. The subject is one that merits experimental study. SEXUAL VARIATION. The range of sexual vajiation ii» North American VespertHionUliV is always slight and in i:aiiy cases scircely api)reciable. For tlie most part it consists in the slightly greater average size of the fenmles. Even this is often trilling or absent, as in the case of Mi/otis luci/mim lotifficrtis from Nicasio, Cal., six males of which average: Total length, 1>5.1; tail vertebra', 4.5.S; forearm, .'?7..S; ear, 11.8; tragus, 7.3; while six females from the same locality average: Total length, 9().3; tail ver- tebra*, 44.1; forearm, .37.3; ear, 12.1; tragus, 7.2. In general, however, it is necessary to take this factor into (jonsideration when comparing specimens from wid<'ly separated localities. I know of no instances of constant sexual differences in color among North American Vesper- tilionidn', and oidy one of ditlerences in cutaneous structures, that of hhofjei'ssa ffmcUis, in which the only known male has in each ear a distinct glandular swelling, absent in the two females that I have examined (see PI. I, fig. 7). AGE VARIATION. Young bats when nearly full grown often present characters different enough from those of the adults to cause confusion in ideutiflcatiou. The fur of such immature specimens is usually shorter and more woolly OKOORAPHIC VARIATION. iddition to than that of tlieadultHHixl th iiiiiiiatiire Hkull dill'ers in si/.e and torni t'roni that of the adult, but as the sutures disappear at an early ajje. it is (d'ten somewhat ditllcult to recojjni; <,'. 1 have found that tlu- best j;«'f the linger Joints.

C, are uot distinguishable from a series taken on Kadiak Island, Alaska, and skius of Lafiiurux cinercus from Minnesota are exactly like others from southern California. While such constancy of characters in wide ranging species is unparalleled among American mammals, the only ones of which it is yet possible to Kui. 1.— Whirls of Vfspertiliv terotinut : a, ndult; f<, ininiatnrf (natural size).

''See ta))lc of lueaaureiueuts on page 120. 10 NORTH AMERICAN FAUNA. ■ 4 I 5 speak with certainty, the ex])htnation f>f the fact is probably very sim- ple. Living throughout the warmer part of the day in cool, dark, and for the most part damp situations, bats, even in widely separated locali ties, are exposed to comparatively little variation in teni[>eratnre. Feeding Jit a distance above the surface of the grourid and during the hours between suusel and sunrise, when colcrs are scarcely distin- guishable, they art. practically freed from that necessity for protective coloration which binds the color of most manunals so closely to that of their surroundings. From this reduction in the force of two of the most powerful factors in the production i>f geographic variation — dif- ferences in temperature and need for proicctive coloration — the com- parative constancy in the characters of bats naturally results. III 1 1; GEOGRAPHIC IJISTKIIJUTION. From the peculiar habits of bats it results that the rjinges of these animals are less closely limited by life areas tiian in the case of most mammals. To be more accurate, the frequent dampness and usual low, even temperature of the retreats occupied by bats during the hot part of the day expose the animals to essentially similar conditions wherever they msiy be, so that a given region of like environment is much more extended geographically for a bat than for most other tnammals.' Therefore, although many species seemingly disregard the laws of geographic distribution, their indei»endence is more apparent than real. MIGRATION. A factor which introduces much uncertainty into the study i>i' the distribution of bats is the little understood migrations which son)e species are known to make. That many bats migrate is a well-estab- lished fact, but the extent to which migration alltects the apparent dis- tribution of species is not known. Although there are probably earlier references to the subject, the first mention of bat migration that I have seen is by Dobson, in his Catalogue of the Chiroptera in the British ^luseum, publislied in 1.S78. In his remarks on the geographic distribution of PijmtreUm abramunj Dobson says: "Found during the summer months in the Pahearctic region throughout middle Kurope; • * * evidently migrates north- ward, * * * as it has never oeen taken in Kurope in winter" (p. 227). In 1888 Dr. C. Hart Merriam published evidence in the Transactions of tfie Royal Society of Canada (V, Section V, p. 85), which showed con- clusively that two American bats, Lasionifrtcriii nnctivmjans and Laai- uniH cinereuif, perform regular periodical migrations.

In August and September, l.S!)0 and 18!H, I had an opportunity to watch tlieai)pearanceand disai)pearance of three species of bats, Lasi- OHjHtens noctiraganx, Lasiuriis borcalix, and LasiHruH cinenim^ixt High- land Light, Cape Cod, Massachusetts. The animals, which were not to be found during tlie early summer, suddenly became numerous shortly after the middli! of August and remained abundant for about a month, when they as suddenly disappeared. Tiie regularity w ith which this phenomenon occurred on the two successive years over which my obser- vations extended shows that the migration of bats is probably as defi- nite as to dates and paths as that of birds.' MEASUREMENTS. For general purposes of identification, ten measurements are useful. Tlicscare : Total length, tail vertebra-, tibia, foot, forearm, thumb, h>ngest linger, height of ear from meatus, width of ear, and height of tragus.

TT 12 NORTH AMERICAN FAUNA. ILHSTEATIONS. The illustrations in this paper are reproductions of ])en-and-ink drawings made under luy constant 8ui>ervision by Mr. Frank Miiller. Special difficulty has been encountered in obtaining satisf;n'tory repre- sentations of the external ear and of the crowns of the teeth. The ears of a1coholi<* sjieciniens are generally snfHciently altered in form, by pressure and by the action of the preservative fluid, to retain only approximately the appearance which they had in the living animal. Tliis is especially the case with such large-eared si)ecies as Anfrozou.s i}alUdiig, CorynorhinuH vmcrotia, Myotis erotis. and others. In the impossibility of reproducing their original appearance, it has been thought best to represent the ears in a uniform but somewhat unnatural jjosition, with the conch flattened and the external basal lobe turned outward. This will account for the apparently undue width of <-ertain drawings. Tlie crown views of the teeth were tirst sketched with the aid of a camera lucida and afterwards corrected and finished by the use of hand lenses. The great dilliculty in obtaining accurate and uniform results arose from the im))ossibility of keej»ing specimens in exactly com- parable positions and from the considerable changes in outline result- ing fron) every slight variatioji in the angle of vision. Therefore the drawings are not wholly satisfactory. They are published, however, in the belief that, such as they arc, they may helj) to an understanding of the characters of the species. NOMENTLATURE OF NORTH AMERICAN VESPERTILIONID-E. To arrive at final conclusions in regard to the nomenclature of the VeK}H'rtilitini(la' of North America, it will he necessary to consider in detail all names that iiave been based on those members of the group that inhabit the region in question, aiul also a few based on allied Old World species. The names may best be taken up alphabetically. 1. Oeneric and Subgeueric Names. Adeionyct«ri8 H. Allen. 1892 { Proc. Acad. Nat. Sci., Pliila..

Since this si)ecies is conj^eueric with Vesperfilio miirinuH Linua*us ( = Vexperuyo (Uwolor Natterer), the type of the genus Vefipertilio, the name Eptrxicvx is a synonym of Vcspertilio. Euderma II.

Eistiotus Gervais, 1855 ( E.\pe. was basetl on the South American Plevotus velatuH of Geoffroy. Euderma maculattnn was originally described as a member of this genus, the name of which has not otherwise api)eared in the literature of North American Vespertilionidu'. Hypexodon Eafines<|ue, 1819 (Journal de Physique, de Chimie, d'His- toire naturelle et des Arts. LXXXVIII, p. -417), can not be identified with any known group of bats.

The name has been amended to Rhoyiiesm by Marschall (Nomenclator [Zoologicus, Mamm., p. 11, 1873). Scotophilus Leach, 1821 (Trans. Linn. Soc. London, XIII, pt. l,p. (J9), Itype S. huhlii Leach, is a genus peculiar to the Old World, where it jupparently replaces the Lasinrus of America.

Vesperides Coues, 1876 (in Coues and Yarrow, Zool. of Wlieeler's Exped., p. 83), was proposed as a subgenus of Vespertilio based on Vex- pertiliv nocUvagans Le Conte. The name is antedated by Lasionycteris Peters, 1865. Vespertilio Linna»u8, 1768 (8yst. Nat., 10th ed., I, p. 31), contained seven species: rampi/rus, spectrum, perspiciUatns, Hpamna, kporimis, auritus, and murinus. These have all been removed to other genera, as follows: vampyrus to Ptcropm in 1702 (Brisson, Hegn. Anini., ed. II, pp. 13, 153), leporintia to Noctilio in 1700 (Linna>us, Syst. Nat., 12th ed., p. 88), spasmn to Mcgaderma in 1810 ((ieoflroy, Ann. Mus. d'Hist. Nat., XV, p. 197), auritui to Pleeotna in 1818 (deoffroy, Descript. de Pr5gyi)te, Mammiferes, p. 112), murinus'^ to Eptem-ux in 1820 (Kafinestpie, Annals of Nature, 1820, p. 2), pempiciUaUiH to Artibeus in 1821 (Leach, Trans. Linn. Soc. London, XIII, p. 75), and spectrum to Vampyrus in 1821 (Leaeh, Trans. Linn. Soc. London, XIll, p. 79). The only European species are auritus and murinus, one of which irnist therefore become the type of the genus. The species auritus was removed to the genus Plecotus by Geott'roy in 18 8, leaving murinus as type of the genus Vespertilio. The Vespertilio murinus of Linnu'US is, however, a totally different animal from tlie bat afterwards described under the same name by Schreber. To understand tlio case fully it is necessary to go back to the first and second editions of Linnieus's Fauna Suecica. In the first he records only one bat, the 'Liiderlapp,' 'Fhidermns' or 'Nattblacka,' Vespertilio caudatus, naso oreque simplici (No. 18, p, 7, 1740). In the second edition he mentions two, V. caudatus, naso oreque simplici, auricidi duplicatis, cajnte majoribus, and V. cau- datus, naso oreque simplici, auriculis capite minoribus (No. 2, pp. 1, 2, 1701). In the tenth edition of the Systema Natura; these had been given binomial names, Vespertilio auritus and r.wtjomw*, respectively. The account of the teeth of the latter in the second edition of Fauna Suecica is as follows : •' Deiites i)riniores supcriores 6, acuti distantes. inferiores 4, acnti contigui. Laninrii superiores 2, anterioio inajore. inferiores 3, antico niaxiiuo. Molares utrini|ue 3, tricuspidati. ' Sitziingsber. K. Akad. Wiss. Wien, LXII, Iste Abth., p. 402, 1870. i^Althongli Rafiiiesqno did not actnally place the species murinus in the genus Eptesicus he based the hitter on a strictly congeneric form. »In the first edition the dental formula is the same, except that the lower incisoiH are said to be five in number, an error corrected in the second edition.

The current nusidentification of Linna'us's Vcspertilio mnrinus has |l)een recognize*! by at least three writers on Kuroiiean bats, Nilsson, Jlasins, and Lill.jeborg. Nilsson^ discusses the matter at considerable ^ength and arrives at the conclusion that the name miirinuH must be substituted for (UncoIo); while the bat commonly known as murinuH nuist take the specitic name myotia Bechstcin. As this author unites the genera ' Vespfruffo ' and ' Vexpertilio,^ he has nothing to say in regard to the validity of the generic names used by Keyserlingaud lilasius. lUasius' regarded Nilssou's identitication of VcHpcrtllio ini(riHu.s -as jdoubtful, though he admitted that the aninnil described by Linna^is under that name c(mld not have been the one generally called Vcupcr- alio murinun by Kuiopean authors at large, lie therefore reasoned that iiinna'us's-namc might be disregarded as undeterminable and iu ^lo way invalidating Schreber's later application.

The peculiar cok)ring of this si)ecies, unique among the bats of the eastern I'nited States, is very accurately described.^ This is the iirst account of an American bat in which this color pattern is referred to. The mixture of dark and light hues in Ouvier's V. (jeonji (uins is due to the shortness of the fnr in his spe(!imen, which allows the dark bases of the hairs to appear irregularly on the surface. This is not at all the case with the small ripistrellus of the eastern United States.

Its ]>ecul- iiir color at first suggests albinism, but since the fur is everywhere dark iit base, even in the white areas, the pattern is probably normal. It is iiseles.s to hazard any conjecture as to its probable geographic range or exact fauiial position. Tiie following note- on this bat is kindly furnished by Dr. C Hart Merriam: Tlie type of this remarkable genus and specii^s, recently described by Dr. J. A. Allen, is believed to have been obtained at the month of Castac Creek in the Santa Clara Valley, near San Fernando, Cal. The type specimen remains the only one thus lar collected, bnt the H]>ecies probably ranges over much of the Lower Sonoran Di'surt region in summer. While in Vegas Valley, N«>v., I was told by the Stuarts, tliu owners of Vegas Ranch, that a very large bat " with cars like a jackass and a white iitripe on each shoulder" is abundant at that place in the summer, but does not occur in spring or fall. They stated that it had not yet arrived at the date of our visit, May 1, 1891. Genus CORYNORHINUS H. Allen. I8;{1.

MYOTIS VELIFER. 57 Genera] charnrierH, — Largest species of Myotin known to occur in Mexico or the United States. Length DO to lor>, forearm 40 to 47. < jilcar slender, without well developed lobe. Free border of uropata- gium naked. Ears short, reaching tip of nose. Wings from metatarsus. Earg. — The ears are short and pointed; laid forward they i-each to or just l>eyond nostril. Auricle concave on both sides inimcdiately below the narrowly rounromincnt basal lobe, which is slightly uotrheil on the lower side and joins the side of the face in a line which if continued would coincide with the margin of the upi)er lip. Tnigns niodeiately long and broad, the anterior «»steri«n" border bends rapidly forward to the ti|>, below which it may be either straight or very slightly concave. Mrmhrams. — The membranes are, for an American Myotis, rather thi«k ami opaque. The uropatagium is sparsely haired both dor sally and ventrally on its proximal fourth; the free border, which is distimtly shorter than the calcar, wholly naked. Wing from i>oint U'tween ankle and base of toes, but nearer t)ie«latter. When drawn :iway iM*rpendicnlarly from the leg, the wing appears to be atta(;hed to tli«' ankh'. Fni. — Feet ( IM. IT, tig. 0) large and strong, half as long as tibia-. Toes iwit'iout claws) slightly longer than sole, scarcely united by membrane ;it ••\frcme base, all sprinkled with long, stitf hairs. Calcar long, slen fl« r. usually terminating indistinctly, but sometimes with a more or leas \v«"ll defined lobule at tip. Fur and color. — There is nothing jtecniliar ut bigh and com pressed, with well develoi)ed ridges. Distance from posterior border of last upi)er molar to tip of hamular equal to or less than distance between alveoli of posterior molars. Teeth. — Upper ineisiors diverging at tips, the inner tooth of each pair much the larger. First and second premolitrs in the tooth row or second displaced slightly inward and partly concealed by the anterior etige of the third, the relative size of the two teeth variable, but first always the larger. Tlie second premolar is always much shorter than the first, but the cross section of the crown is sometimes ne;u-ly espial in the two teeth. On the other hand, in rai-e Ciu«es the area of cross sec- tion in the first is nearly double that of the second. Third up|)er pre- molar triangular in outline, posterior margin Umgest. the outer margin abruptly convex anteriorly, the anterior and posterior Imrders slightly concave; inner apex of triangle bluntly rounded and not rejicliing to level of inner margins of molars. Crowns of first and second up|>er molars trapexiform in outline, the anteriin* edge longest, and the ]>oste- rior, outer, and inner edges successively shorter. Anterior edge slightly convex, posterior edge slightly con<'ave. Crown of first molar consiil- erably shorter in ])roportion to its width than second (fig. 14 J, p. Gl). Inner mandibular incisors smallest, their crowns compressed and trifid; middle incisors similar but larger; outer incisors aliout as large as the two others together, their crowns irregularly terete, and with f<»ur indis- tinctly developed tubwcles, one of which is much larger than the others. First and second premolars i)erfectly in line, the first considerably larger than the second, though not much wider in cross section.

The hiiirs are iiverywiiere dusky shUu at bane, (ieneral cohir dull brown with a di8tin<;t gloss in certain lights, the ventral 8urfiu;e paler and more yellowisli. The exiust shtules are vari- able. Thus in three s|>eciniens taken at Washingtiui, 1). C, in flune, the color of the back is respectively wood brown, raw umber, and sepia, the belly in each pale wood brown tinged to a varying degree with gray. In the majority of individuals the color tends towsird sei>ia. Seven skins from Elk liiver, Minn., and three from Kadiak Island, Alaska, are indistinguishable in color from those taken at VViishington. Ears and membranes light itrown.

Ithoatls I have examined the tyi>e :iiid six topotypes of Vtspcrtilin lnci/iiffnn aiintrorip(friuM from Tar]N)n Springs, Fla. 1 can tind no chaiacters by which these specimeus may be distinguished from those taken at othtM- parts of the range of Myotis liiri/iitfUH. The two skins, one of whiiUi is the type, are those of partly grown individuals whose immaturity is clearly indicated by the soft, papery skulls in which the nasal sutures are still clearly visible, and by the imperfectly formed Joints of the lingers (see tig. l,p. 9). These specimens ditfer from northern adults in suuvller size, shorter fur, and duller, browner color. Three adult topotypes in al(;ohoI show only «me of these peculiarities — the shortness of fur — antl iu the fourth this also IS absent. The fifth alcoholic spccinu'ii is imtniiture. That the adult .specimens of Myotic from Tarpon Springs are uot smaller than .1/. liici- ftiffiix from oth'ir localities is clearly shown by the table of measurements on page do. The short fur of three of the adults is evidently a sesisonal character, since all showing this peculiarity are in worn, ragged «*oat, while the only one in fresh pelage (killed Septi^mber 1!J) has fur of tlie ordinary length. The fur of all these specimens, after nearly five .years immersion in alcohol, has lost the warm, glossy appearance char- acteristic of freshly killed iiidividiuils, It can be perfectly matched, however, among the series of alcoholit; specimens collected in Center County, l*a., during the winter of 189;j.

Anterior bonier of auricle regularly convex from base to a point slightly beyond mid- dle, thence straight or nearly so to the tip. Posterior lH>rder slightly ctmcuve immiMliately below tip «»f ear, then gradually and nuNlerately convex to base. Masai lobe strongly develofied, and notched on the lower border. The auricle is usually niarke\ver end of the concavity which extends downward from the tip of the tragus, in other cases separated from the latter by a region of varying extent in which the posterior and anterior borders are parallel. These variations bring about striking contrasts in the form of the lower part of the tragus in ditferent indi- viduals, and suggest the existence of more than one species or race. Specimens from approximately the same region, however, show both extremes and intermediate conditions. Membraneit. — The membranes are thin and light.

Whole dor- sal surface of foot sprinkled with stitl' hairs. Calcar distinct, equal to or longer than free Irarder of uropatagium, terminating in a lobule of varying distinctness. Posterior border never distinctly keeled. Fur and color. — The fur is full, soft, and not peculiar in distribution. It is light yellowish brown, paler ventrally, the hairs everywhere dusky slate at base. The absence of a series of skins of this bat makes it impossible to describe the color accurately or compare it in detail with that of its allies, M. thyHanoile» and M. Mubulatux.

General remarls. — Pipistrcllus subHavus obscurus is readily distin- guishable from true subjlavus by its darker, duller, less yellow color. The //««•»<«, dull isabella color in obscurus. The darker hue of the back in obscurus is due partly to dirt'erences in the color of the long hairs, and of the middle bands of the short hairs, and partly to the more extended dark tips of the short hairs. Like the typical form, Fipistrellus subflarus obscurus varies considerably in color, so that individual specimens of either sub- species, especially those that .are not fully adult, are sometimes difficult to identify. When series are compared, however, the difterential char- acters at once become apparent. PIPISTRELLUS VEKi^li^CRUCIS (Ward). 1S91. lesperiigo rcrovt> which the greatest width is (|uickly reached.

General eharaeters. — Size, large (forearm, over .')Omm.); prevailing color, gray; ears with black rims; forearm with distinct patch of fur uear base. Earn. — The ears of Lasiurus einereus are in general similar to those of fj. borealis, but are broader in proportion to their length (see table of measuremeuts, p. 115). The external basal lobe is less developed thau LASIiriiUH CINEKKl'S. 113 ill horealiH and without trace of iiotcb on anterior border. Margin of ear ineuibrane dark brown or bhickisb. Outer side of ear densely furred to a little beyond middle. Inner side witli eonspieuous patch of yellow- ish hairs above and in front of middle and a border of similar hairs along lower part of anterior edge. Tragus shaped as in L. boreatis, covered with sparse coating of hairs on outer side. Membranes. — In form and attachment the membranes are as in L, borealis. Feet. — Foot about half as long as tibia; dorsal side thickly furred. Calcar twice as long as foot and slightly shorter than free border of interfemoral membrane, it is distinctly though narrowly keeled on posterior edge, and usually lobed at tip. The terminal lobe is very variable, and may be well developed ou one side and absent ou the other. Fur and color. — The fur is distributed much as in L. borealiH. As in that species, it is distinctly longer on neck than on back, thus forming a ruff. On the neck it aver- ages about 15 mm. in length, on the back 11 mm. General color, a mixture of light yellowish brown, deep umber brown, and white, the yellowish brown clear and un- mixed on throat, head, and under side of membranes, the umber brown predominat- ing on back and dorsal surface of interfem- oral membrane, where, however, the hairs are mostly tipped with silvery white, some- times to so great an extent as nearly to conceal the dark tints beneath. Lips, chin, and cheeks sprinkled with short blackish hairs. Ventral surface with white predominating on belly, between whi<;h and yellow of throat is a band iu which the umber brown is more conspicuous than else- where on the under parts. Tufts of fur at bases of thumb, fifth finger, and forearm, light yellowish brown, like fur ou under side of wing membranes. On middle of back the individual hairs are colored lis follows: Deep plumbeous at base; light yellowish brown (shiuling toward amber distally) through middle half; umber brown subapically; silvery white at tip. Color variation is considerable, but never enough to obscure the char- acters of the species. It appears to be wholly indei)eudeut of locality, as skins from such widely separated localities as Minnesota and south- ern California are practically indistinguishable. One skin from the Sautee Kiver, South Carolina, has the dusky tiuts throughout the pelage so intensified and extended as Xm suggest melan- 2772— No. 13 8 Fio. 31.— Sknll of Ltuiuru* einereui (X2).

It is distinguisbed from tbe latter by smaller size and ai>parently also by paler color. A translation of Gundlach's second and more perfect account of tbe animal is as follows: "Pelage above ligbt tawny (tlie fur blackish at base), beneath pale reddish tawny (the base of the fur likewise black- ish). Face and flight membranes blackish brown. The nose ajtpears somewhat divided by the projecting nostrils; between the nose and the eyes there is on each side a protuberance with bristly hairs. Kars oval, lengthened (8 mm. high in front). The anterior base rounded and spreading outward; the posterior at the angle of the mouth forms a semicircle. This semicircle, which bends inward to the tragus, forms another rounded enlargement. Tragus oblong, scarcely narrowed tbroughout, somewhat bent in the form of a sickle forward and pro- vided with a tooth shaped lobule at the base of the exterior border. Nails tcawny.

Remarks. — The genus Rhofiei'usa has received varying trcJitment. It was originally described as a full genus whose relationships were sup- posed to be with NyctiveiuH and NyvtinomuH. In 1S7S Bobson referred it to ^Vrsperuyo^ ns a subgenus. This view has been adopted by most subsequent writers ex<'ept Mr. Oldlield Thonuis and l>r. Harrison Allen, both of whom have recognized Rhoyd'Hrn as a full genus related more closely to NycticeiuH than to any of the genera usually included under the name ' VespcrufioJ' Mr. Thomas has pointed out characters in which h'hogecssa resembles Antro- zoHn. These chaiacters, the reduced size of the outei- lower incisor and slightly creiuilate posterior border of tragus, seem to be instances of parallel de\elop ment rather tin. indications of genetic relation.ship. The genus Rhoflei'Ksa is closely related to Nyetictiits, but the peculiarities of the lower incisors nnd the general form of the skull are enough to warrant its recognition.

Fur and aAor. — There is nothing peculiar in the distribution of the fur. It extends in a very narrow line on the wingH along the side of the body both dorsally and ventrally, and on the uropntagium rovers the basal fourth dorsally but scar-ely reaches the membrane on the ventral side. In color the fur is dull yellowish brown throughout, scarcely paler ventrally, the hairs dusky at tip. Ears and membranes dark brown. Skull. — In general appi'arance the skull of Rhotfeessa tumUla (fig. 39) stands between that of Xydiceiux humeralis and Pipistrellus suhHavutt. The skull of an adult female from Santo Domingo, Oaxaca (No. 73267, United States National 3Iuseum, Biological Survey collection), meas- ures: Greatest length, 13; zygomatic breadth, 8.4; breadth of rostrum at anterior edge of first molar, o; mandible, 9;' upi^er tooth row, .5.6; lower tooth row, 6. That of an adult female from Patuca, Honduras (No. 21017,1'nited States National Museum), meas- ures : Greatest length, 12.4; zygomatic breadth, 8; breadth of rostrum at anterior edge of first molar, 4: mandible, 9.4 ; upper tooth row, 5; lower tooth row, 6, The rostrum is relatively narrower than in Xycticeiug and the occiput is more elevated. The muzzle is distinctly concave in front of orbits instead of flat or almost convex as in Xycticeimt. Teeth. — Upper incisor usually in contact with canine, though occasionally separated by a narrow space (fig. 40fl). Maxillary teeth essentially as in Nyctieeius, but premolar relatively larger and posterior molar narrower in proportion to its length. Lower incisors greatly crowdetl, the outer cnsp of * 1 and i 2 much smaller than middle and inner cusp. Outer lower incisor uni uspi date, about one-half the size of i 1 or » 2.

The color appears to differ sliglitly from that of ^. tumida, but I have too few skins to make an adequate comparison. Skull. — The skull of the type and only known specimen Is so much injured that its characters can not be determined with certainty, but it appears to be smaller and relatively narrower than that of R. tumida.

General remarks. — Rhogei-xsa minutilla is a small insular form most closely related to R. tumida, but apparently perfe<*tly distinct. So far as I know the genus Rhoyei'sxa has not yet been recorded from the mainland of South America, where, however, it doubtless occurs. ,. RHOGEES.SA I'AKVULA II. Allen. 1866. Rhogti'-$Ka parvula H.

Geographic dintributivn. — Southern Mexico (I'uebla and ' Isthmus of Teh nan tepee'). General eharacfers. — Size, medium; length, 79 to 82; tail, 3H.0 to 41; forearm, 32 to 33. Calcar slender but distinct, a little shorter than free border of uropatagium, terminating in a small lobule, distinctly keeled on the posterior border. Free border of uropatagium naked Ears long ; when laid forward extending about (5 mm. beyond tip of nose. Wings from base of toes. Feet and legs long and slender, the outstretched feet reaehing to within about 10 mm. of tip of tail. Ears. — The ears (PI. I, Hg. 7) are long, and at the same time broad; laid forward they reach about mm. beyond tip of nose; the substance of the conch thin and translucent. Anterior border strongly convex from base to a little below middle, then straight or very slightly con- vex to the rather broadly rounded ott' tip. Posterior border concave below tip to about middle, where it bends abruptly outward, then grad- ually convex to base. A very faintly indicated basal notch and basal lobe. About 5 mm. above the crown and an ecpial distance from the tip of the ear conch in the male is developed a conspicuous, flattened- pyriform, glandular thickening with the large end toward the anterior margin of the ear and the main axis nearly perpendicular to that of the auricle. The thickened mass is 5 mm. in length, 4 mm. wide at the broiul end, 2 mm. at the narrow end, and 1 mm. thick. It is most con- spicuous on the dorsal side of the ear, where, although not dift'erent in color from the rest of the ear, it is noticeably raised above the surface, and the boundaries are sharply marked. On the inner side of the ears the thickenings are less definite in outline, but are noticeably paler than the surrounding integument. When these structures are examined with a lens it is seen that they are thickly covered on the Kn(>(JKi;s«A GRACILIS. 127 outer side witli pores lyiiij; mostly at tlie bases of the flue hairs with whieli the stirface is beset. The tliickeiied insjsses are of exactly the same si/e and shape \i\ the two ears and are placed symmetrically with respect to the outlines of the conclis. Trajjus slender and taper ])oiuted, slijjhtly bent backward at the tip, and broadest opposite anterior base. The anterior border is slightly concave at base, then evenly convex to tip. The posterior border is strongly concave from tip to a ])oint slightly above the middle, where the tragus attains a width nearly equal to that at level of ante- lior base. From this point to the basal lobe the i)osteri(»r border is nearly straight and about parallel with the lower part of the anterior border. Itasal lobe small but prominent. Posterior border of tragus crenulate, espe<'ially near the middle, where there are five or six minute sharply projecting points, from the bases of which thickened processes may be traced a short distance into the substance of the tragus when the latter is held to the liglit. Mfmhrajics. — The nu'inbranes are thin and semitrans]>arent, the uro- patagiuni not different in texture from the wings. Throughout they are entirely nakeer molar is couHlderably broiider. The front lower premolar is sli^^htly larger thau iu U. tumida, but otherwise the mandibular teeth show no distinct difierenees. Meamirements. — See table, page 129.

Oeneral remarks. — Rhoge- I'ssa gracilis is so readily distinguished fromtbeother species of the gejius by its slender form and very large ears that no detailed comparisons are necessary. This is the only species of North American VespertUionida' in which I have found any sexual diU'erences in cutuneous structures. RHOGEi-'SSA ALLKNI Thouias. 1892. Rhogeessa alleni Thomas, Ann. & Mag.

Oeoyraphic distribution. — Rhogei'ssa alleni is known from the type locality only. Characters. — As I have not seen the type and only knoMu specimen of this bat, I copy Mr. Thomas's original des»jription : "Decidedly larger than Rh.parvula; muzzle obliquely truncate as in that species. Ears large, laid forward they reach about 1 or 2 millim. beyond the nostrils; their inner margin very convex forwards below, straight or even slightly concave above; tip narrowly rounded off; outer margin concave below the tip, then straight, becoming slightly convex below, outer basal lobe but little marked. Tragus long, its broadest point opposite to base of its inner edge; inner edge straight or slightly concave, tip rounded, outer margin slightly convex, the edge indistinctly crenulate, somewhat as in Antrozons pallidus; a marked lobule at the base of the outer margin, above and below which there is a concavity. Thumb very short and th ick, no longer than in Rh. parvula. Posterior edges of wing-membrane bordered with whit«, bifid tip to fourth finger unusually distinct; wings from the base of the fifth toe; post-calcareal lobe small and narrow ; tip of calcar projecting slightly from the back of the membrane; tail included in membrane to the extreme tip."
