 1895 
 
 
Tlie first p;ut of tliia, the second, volume of Contributions to Canadian 
 Palu'ontolof,'y, consists of three illustrated papers by Dr. S. H. Scudder, 
 of Cambridge, IVFass,, to whom the Survey is greatly indebted for his 
 gratuitous labours in the interests of science. 
 
 Two of these papers are devoted to descriptions and illustrations of 
 Tertiary and Post-Tertiary insects from British Columbia, and the third 
 to descriptions, also illustrateti, of Myricipods and Arachnids from the 
 Carboniferous rocks of Nova Scotia. 
 
 Although begun under the title " Canadian Fossil Insects," it has 
 been found convenient to include the third paper on Myriapods and 
 Arachnids in this part of volume II. of the " Contributions." 
 
 The specimens upon which the decoriptions are based are for the 
 most part in the Museum of the Survey. 
 
 The drawings for the five plates which accompany this publication were 
 made by Mrs. Katherine P. Ramsay and Mr. J. H. Blake, under Dr. 
 
 Scudder's supervision. 
 
 A small separate edition of each of these papers has previously been 
 supplied to the author and distributed by him.

 Similkaiiu'cu Itivcr, and Nine- .Mile Creek tlowiiii,' into Wiiipsaw Creek, 
 ii trihntan of the Siinilkanieen : Imt in Dr. Dawson's view the two 
 latter (le|M)sits nniloiihteilly I'ortned ilitVerent poiMions ot' a single lake, 
 so that really only two basins are eonei'rned. Cnrionsly, these two 
 basins afford s|ieeiMiens of very different eharaeter, for two family 
 groups arc represented only at Quesnel, four in 'he Siinilkaineen basin 
 only*. 'I'he only other known locality for fossil insects, Nicola, has 
 yieldi'd no lleniiptera. 
 
 Nineteen species in all have lieen found, and notwith; tandins,' the 
 Hundl number, they prove very interesting. Oidy two of them, a water- 
 Htrider and a shield bug, belong to the heteropterous division, the re- 
 niaiinler being liomo|iterous, an extraordinary disproportion. So, too, 
 the families of Ilomoptera are very unevenly represi'nted, the Cerco- 
 l>idie with eleven spei'ies being out of all proportion to the otliers, — 
 the Jassidse with one, the Aphidida' with two, and the Fulgoridu' with 
 three spi'cies. The Cereopidie therefore give the characti'r to tlu' 
 fauna. 
 
 Oiu' of the first things that impi'esses the student is the great variety 
 among these insects. In every case, at least among the Ilomoptera, 
 every specimen must be referred to a distinct species, and in only one 
 ease can two species be referred to one genus. In the Fulgori<la' each 
 of the three species belongs to a different subfamily ; and though such 
 a diff'erenee is imi)o.s8ible in the here more numerous l)ut I'verywhere 
 less varied Cereo])ida', the range of genera is very considerable. Given 
 the number of species allotted to the different families as here, one 
 could hardly devise a more e.\tveme case than here presents itself.

 i''rnm the insect data one can make no stronif assertion reirardini-- the 
 relative aj;e of the deposits in which they o.'.Mir, hut there are one or 
 two points to wliicli it may he well to direct attention. One is the 
 fact that nearly all tlie Lreneric groups represented are so far as km. ,ii 
 exliucl ; even the few which arc hen' placed in existini; ■'eiierii,— 
 Knchophora. Iticaiiiii, C.i'lidia, C'ereopis. Aphropln>ra.— are in nearly 
 every case so |. laced only provisionally from the incompleteness of the 
 specinu'ns found ; this would surely seem to indicate a rclalively jrreat 
 at;e, at least as oh! as the oliLroceiie. .\uothcr is the reference of a 
 few, generally with cerlitmie, to u^'nera, -Gerancon, Shenaphis. Palec- 
 phora. I'alaphrodes, — known otherwise (udy from American heds re- 
 ferred to tlie oliiiocene ; and hesides these the only species elsewliere 
 recorded is found likewise in the oligocene. The last fad, however, 
 
 looks in a diffcrciii directi for the cercopi.l element of the fauna, 
 
 and as we liave seen its nnist important i'ompoiient, shows a distinct 
 rescmlilaiicc to that of liadoboj in Croatia, which is regarded as mid- 
 dle mioccne.

 two species of plant-lice, temporarily refcrrinj,'each to Lachnus. None

 these insects fnjm ihe American tertiaries shows a remarkahle variety 
 of fossil forms and compels the estahlishment of a lari^e numher of

 A fra^-inent of a wing is sufficiently preserved to siiow that it should 
 he referretl here. The wing is unusually slemler ; the postcostal vein 
 thickens ap'.-ally as it merges in the stigma; the tirsi ol)li<|Ue vein is 
 straight ; the secoml originates very close to the first, runs parallel to 
 it only at the very base, ami then bends pretty strongly outward, strik- 
 ing the margin of the wing nearly as far from the tip of the first 
 oblitiue vein as half its own length ; the origin of the cubital vein is 
 not clear, but it is apparently not far out, in w liicli case it rims parallel 
 with the second tdiliipie vein until it branches in the middle of the 
 wing ; the lower of these branches almost retains the course of the 
 basal part of the veins, but diverges slightly from the second obliijue 
 vein, terminating very far from it on the border of the wiiiir; the 
 main stem, iliverging from the first branch rather wiilely at first, 
 almost at once runs parallel to the lower brjincli, and when it has 
 continued a less distance than the main vein before its furcation, 
 divitles, the two forks diverging but slightly at base, and then very 
 gradually converging until they are no farther apart than tlie basenof 
 the first and second oblitpie veins, ami the upper fork almost touches 
 the sligmatic vein (probably by some ilisplacement ) : together they 
 diverge a little from the lower brandiof the cubital vein ; thestigmatic 
 vein is very conspicuous, passing by a broad swee]. into the heart of

 angle with the jiostcostal vein of less than forty-live degrees ; is no-

 first hraiich at slightly less than a millimeter from its hase ; forms 
 with it an angle of twenty-live degrees, and at an eipial distance farther 
 on emits its second branch at a similar or slightly smaller angle ; hoth 
 the branches are perfectly straight, and the iip]H'r branch of the last 
 fork lies midway between the lower br.aiich and the stigmatic vein ; 
 the latter is similar to that of </. ji •■kiii from the same beds, but is 
 not so strongly curved ; the first branch of the cubital vein also divides 
 e(|ually the space between the second obliipie and the lower branch of 
 the last fork of the cubital vein. The obli(]ue veins of the hind wing 
 (see above) originate at no greater distance apart than the first and

 This name is pr()|iosed for a gcnns of Fiilgorida' ajijiarently belong- 
 ing to tbe Dt'ljihacin.- but dilTering from all Ilonioiitera I have seen 
 in the rcniarkal.l.- 1 ■, i of the ])rinci]ial veins of the tegniina, nearly 
 all of which, .ind '•■ 'uinly all the bi'ancdies of the radial, as well as 
 most of the branches of the idnar vein, terminate njion the costal 
 margin, the costal areole being very brief, or less than one-third the 
 length of the tegmina. The radial vein branches very near the base 
 of the tegmina, and its lower branch again a very little way beyond, 
 all three of the branches running in a sti'aight course parallel to one 
 anotlu'r, and embracing at tip the middle third of the margin. The 
 ulnar vein forks near the outer branching of the radial vein, the upper 
 branch soon dividing again, the lower dividing beyond the middle of 
 the ti'gmina, all the branches running parallel to those of the radial 
 vein. 
 
 I know of no homopterou the veins oi' wliose tegniima trend as in this 
 genus ; indeed it ajipears to bi' (piite abnormal in this particular. Nor 
 can ^Ir. Uhler, to whom I submitted a drawing, tind any form whose 
 branched veins run toward the costal mai'gin ; but I have in vain at- 
 tem]ttc(I to belii've that I have inti'rchangcd the two margins of tlu' 
 tegmina. In jioint of neuration the tegmina approach most closely, 
 as Mr. Uhh'r has jiointed out to me, to those of ^lnip/ii/<fcp<( hh'ittatd 
 (Say), but even from this it differs widely.

 The s)iecimen is very fragmentary, consisting of an upper wing, of 
 which the whole of the costal border as far as the ti[i, and the basal 
 half of the inner margin can be made out ; but only three iiatches of 
 the surface with its aceom]ianying veins are pi'eserved — a piece next 
 the base, crossing the wing ; another near the juiddle, which crosses 
 rather more than three-(piarters of it from the costal margin backward ; 
 and a greatly broken patch at the upper half of the tip ; but from these 
 l)icc;'s nearly the whole of the neuration, as given in the generic de- 
 scription, can be determined. The costal vein appears to be forked

 a species allied, Imt rather distantly, to the gigantic species of Cer- 
 cojiime descrihed by Ileer from Kadol.oj. It (lifters from them all in 
 iieuratioii, in the form of the costal border and of the apex. Tiie 
 portion of the wing below the straight sntnra ciavi is broken away. 
 The basal half of the costal margin is strongly and rather nniformlv 
 arcuate, but more strongly close to the base; the apical half of the 
 same is nearly straight : the apical margin is a little (d)li.j,iely and 
 roundly excised, gently convex, the tip roundly angiilated. 'i'he costal 
 vein parts from the common trunk close to the biise and follows close 
 to the margin, terminating at about one-third way to the tip ; the 
 radial vein is directed toward the middle of the outer half of the costal 
 border, until it forks, a little before the middle of the wing, when 
 both straight branches run subparallel toward the tip : the ulnar vein 
 also forks once, half-way between the base and the fork of the radial 
 vein, and its straight branches, with those of the radial vein, subdi- 
 vide the outer half of the wing subecpially, all being evanescent toward 
 the apical margin ; the sutiira clavi reaclii's as far as these veins are

 Family IIYDR()]5ATII)/E. 
 
 A single species of this family has heen found in British Colundiia 
 which I formerly jilaced, with reserve, in Ilygrotrechus, but have 
 since studied more carefidly and concluded that it should form the 
 type of an extinct genus, to which also I referred a spt'cies from the 
 tertiaries of Wyoming. 
 
 
 T^:l.^rA■n!I■:(In s Scudder. 
 y'dmatrcckm Scion., Tert. Ins. N. A., :!:> I (I8!)()). 
 
 This genus is closely allied to Ilygrotrechus Stal, and eomhining 
 as it does many of the features of this genus and Limnotrcehus Stal, 
 nniy well have been tlie lineal predecessor of both. The antennae 
 have the first joint only a little longer than the second. The eyes 
 are not at all prominent. The thorax is relatively shorter than in 
 Ilygrotrechus. The legs are very long, the tibia? of each pair of legs 
 about as long as the femora of the same legs, an equality which I 
 have not found in any other genera of Ilydrobatida^ ; in the fore legs 
 the equality 's perfect ; in the middle legs the tibia> are slightly 
 longer, in the hind legs slightly shorter, than the femora ; the hind 
 femora are slightly longer than the middle pair ; so far as can l)e (old 
 from the imperfect remains the tarsi of the middle and hind legs are 
 much shorter than, not a half or probably a third the length of, their 
 respective tibia'. The posterior lateral edges of the sixth abdominal 
 segment are produced to a tooth precMsely as in Limnotrechus.

 'IMie thorax seems to be shorter than in llvgrotreehus, with the 
 
 limits ot tlie iirosteriiiim more visibly marked trom ahove ; the eyes 
 do not appear to be so prominent, and the tirst antennal ji>int wonhl 
 seem, from the position of the others, to be shorter than in llygro- 
 treehus. The insert is aliout the same size as our // reinft/is (Say). 
 The head, as seen on a side view, is small and rounded ; thorax 
 minutely sciabroiis like the head, narrowing rather rapidly and 
 iinilormly, the |iosterior limit of tiie prosteniiim marked by a slight 
 depression next the anterior coxa', the whole tliorax cojisiderably 
 longer than broad. Abdomen tapering, the aj)ieal angles of the 
 sixth segment jirodnced to a sharj) but short spine, reaching the 
 niid<lle of the siu'ceediiig segment. Antenna' nearly (perhaps (|uiti') 
 as long as the head and thorax together. Kore femora I'ipial, stout, 
 as long as the thorax ; fore tibiie of the same length ; middle and 
 hind legs very slender ; middle femora considerably more than twice 
 as long as the fore femora, the tibise nearly three times as long as the 
 fore tibia' and of the same length as the hind femora ; hind tibia' a 
 little more than twice as long as the fore femora ; tirst joint of hind 
 tarsi about one-fiftli the h'ligth of the hind tibia'. On one of the 
 specimens, preserved on a dorsal view, a line is seen proceeding from 
 either side of tlie thorax, directly in front of the iniddli' coxa', and 
 ])assiiig towiird and nearly to the middle of tlie hinder edge of the 
 second abdominal scgiiieiit with some distinctness, accomjianii'd on 
 the second and thii'<l segments by other lines which seem to indicate 
 the veins of the tegmina, the tirst-mentioned line being tlie sutiira 
 davi ; but all trace of lines is lost beyond the third segment, as if the 
 wings did not extend over more than half tlu' abdomen ; on the 
 specimen preserved on a side \ lew, they appear to extend to the hind 
 edge of the sixth abdominal segment. Attached to the posterior 
 extremity of the abdomen is a jiair of stout lajipi'ts, nearly straight, 
 but curving slightly outward, ecpial, about twice as h)ng as broad, 
 rounded and very slightly produced at the tip. 
 
 In a spccinu'ii (No. 70) which I have considered an immature indi- 
 vidual of this species, but which may possibly be a Metrobates, the 
 middh' and hind femora are of e(pial length.

 The principal spcciiiicn is nniisnally jicrfect, and appears to be a 
 male. 'I'lie head is slightly longer than broad, eipial bcyoiiil the cx- 
 )>anding base, l)r((adly rounded and somewhat flattened in front ; the 
 sliu'lit cariiiic marking the borders of the middle lobe are jtarallcl 
 throtiglioiit and extend to the front of thi' head. The thorax is so 
 iinperfectlv i»rescrved as to throw doubt upon the generic atHnities of 
 the insect, but it ajipears to have been more than twice as broad as 
 long, with a nieilian furrow, and its front margin very slightly con- 
 cave behind the head ; jirobably, also, it was considerably produced 
 at the hinder lateral angles, and had its lateral margin slightly denti- 
 culate anteriorly. The sciitellnui is large, a little narrower than the 
 breadth of the base of the abdomen, of nearly e(pial length and 
 breadth, ]U'etty regularly triangular, but with a slight emargination of 
 the sides on Their basal lialf ; the tip bluntly pointed and rounded olf, 
 extending a little way upon the michlle of the strongly advanced 
 fourth abdominal segment. The surface of the head, protlun-ax, ami 
 scutelliiin is covered pretty uniformly and abundantly with distinct 
 round punctures, which are, howevi r, deepest, most sliarply defined, 
 and so abundant as nearly to occuiiy the entire surface, on the fnnit 
 half of the head and next the margiiis of the prothorax. The corinm 
 of the tegmina includes more than half the wing, and is covered with 
 punctures, deeply imiiressed, and much minuter and more frcfpient 
 than on the sciitellnm ; there is also a distinct vein passing down the 
 mi(blle, a little to cuu' side, and another separating the clavns from 
 the coriuni, but distinct on the specimen only ajiically, where it is 
 continuous with the inner margin of the membrane. The membrane 
 is well rounded, but slightly prodiu'cd at the outer angle, ami the space 
 is occujiied bv nine nearly longitudinal veins, distributed in thre<' sets 
 of three each : the first set is comjiosed of three obscure veins, pretty 
 close together next the inner edge, originating from the same ))oint, 
 (•(piidistant from one another, the innermost hugging the inner mar- 
 gin ; fnuii apparently the same point originates the next cluster, 
 starting in .a single vein, which almost immediately forks, and sends 
 its innermost branch parallel to those mentioned ; the other branch 
 diverges strongly from it and again forks, the two branches running 
 
 'I' 
 
rONIIillsr I IONS lO r'A\AliIA\ I'AI..i:()NTOI.(k;v, 
 
 parallol to tlic tirst ; while from opposite the point of origin ol' tlu; 
 hisl I'oi-k the tliini cluster takes its rise, starting as a sliouldered vein, 
 whicji forks at its shoulder into two slightly <iivergent veins whi<>li' 
 run^ snhparallel to the previous veins ; hut the innermost of these 
 again forks beyond its inicMle, crowding the veins together at tliis 
 J.oint ; there is also a short, tenth, independent vein" close to the 
 outer extremity of tlie produced coriaceous Held. The outer margin 
 of the wiiig is deiicately wrinkled with a simulation of veinlels. The 
 abdomen is ovate, somewliat regularly tapering at its outer half ; the 
 apex obscure but apparently regularly rounded ; tiie pleut-ie are punc- 
 tured like the scutellum, while the dorsal surface is minutely and pro- 
 fusely but obscurely punctulate. Such portions of the chitine as 
 remain are of an intense black. The specimen is a|)parently a male, 
 but whether two snnill triangidar pieces, nearly e(piiangular, following 
 tlie j.osterior edge of the sixth abdominal segment laterally, are to be 
 considered the anal cerci is doubtful. 
 
 Directly beside this specimen, and, in fact, partly underlying it, 
 are the abdomen and part of the sternum of another insect, wldch, 
 although much smaller, should doubtless be regarded as the female of 
 the same speci.-s. This abdomen shows the under surface ; it is 
 very rounded and ovate, the extremity well rounded, the sixth seg- 
 ment rei.resenled by a circuli-r fissured plate, 'i'he sides of the abdo- 
 iiien are punctulate, as in the other specimen, but the punctulation 
 dies out before reacliing the middle of the abdomen. Little can be 
 said of the oilier parts ..f the body, excepting that the rostrum appears 
 to terminate at the front limit of the mid<lle coxa-, and the stermil 
 parts of the thorax are coarsely punctate as above and more particul- 
 :'rly at the margins of the separate pieces.

 hlaj^'i' of insects ever found in such a deposit anywhere. These clavs have 
 been studied and their fossils collected by Dr. (!.,). Hindet, wjio sets 
 forth the reasons why he regard., them as interiilacial, lyini; as they do 
 upon a morainal till of a sjiecial character and overlain by till of a distinct 
 kind. The elytra and other jiarts of beetles found by him rejiresent five 
 families and fifteen .yenera ; they are lar^'oly Carabii'he, there bein-^ half- 
 a-dozen species each of Platynus and Pterostichus, and sjiecii's also of 
 Patrobus, Bembidium, Lori<e. i and i-^laphrus. 
 
 The next family in importance is the Staphylinida>, of which there are

 I'lider this name I am compelled to ]ilace, until further material is ut 
 hand, an elytron of a lietlle which presents certain peculiar features 1 
 have not lieen alile to tind in any modern forni. and liy which it seems 
 to lie allied to the trilic C'l-yptocephalini anion.!;' Chrysomelida'. This 
 feature consists in tiie presence of an apjiareiitly flat, narrow and iiarrow- 
 iny area aloiii^ the sutural margin, correspondin,!,' to that u Inch would lie 
 within the first complete stria of the Crypt ocephalini, and cov<'rin,L,' the 
 longer or shorter humeral stria (where one exists) ; this is accompanied liy 
 an independent arcliinu' of the rest of the elytron with its striie. The 
 foi-m of the elytron, especially its consideralile apical iiarrowini; and the 
 sculiiiiire of its surface, does not a.uree well wiili this ifroup of Chrysome- 
 lida', and 1 am hy no means contident that its place has been properly 
 indicated hy this reference.

 The siiv!j;le elytron is nearly perfect, only a fra;:inent of the outer base

 before the middle of the basal half, narrowim:'. at first gradually, after- 
 wards more rapidly, by the ciir\atur<' of tl liter iiiari:iii. the ajte.K 
 
 rapidly narrowing; on both sides and bluntly subacuminate. There are 
 four blunt and dull-beaded rid.ijes, with ti\t' narrower, sliuhter. and more 
 tiiiely beaded luit sharper riilj,'cs between them and outside the outer ones, 
 while the interspaces are marked by irre.u'ular loimitudinal series of niiiiute 
 beads, all th(> so-called beads bein^- probably shallow puiicta seen in

 A single elvtron is pre.- .veil in a nodule, uhieli contains al 
 remains ot' a lish (MuZ/nfiis ri//ii.<ii.'<, acoo rd in j;' to Sii' William l>awson). A 
 portion of the hlaek ehitine still rciniiins at the hase and tip, and the form 
 of the wiiole and the sculpt uriiii,' of the surface are perfectly preserved. 
 It is most nearly allied to /'. i-alri'iiiKx (Say), Init difVers from it too much 
 to lie placed with it. 'I'lie iiarrowiii.i,' of the elytra is sciircely perot'iitible 
 hefore the distal fourth, wiieic it is distinct and r.ipid. the ajiical angle 
 sliji;litlv less than a riuht an;,'le. it is \-ery distinctly striate, considerahly 
 more so than in /•'. '■(ifcni/iix, the interspaces between the srriie more den- 
 sely punetured even than in that sjiecies, though not so dee|ily, producinj^ 
 a xcrv rut^ulose appearance : the punctuation ap])ears to he disjiosed to a 
 noticealile e.xtent in sliglitly olilii|ue transverse rows, as is also the case in 
 /■'. c(t/rriif)is, and in which there are ahout four or five jninetures across an 
 interspace ; in eticli ])uncture is a circular pit, the ]ioint of insertion of a 
 hair (not preserved), which is only O'Ol""" in diameter, while the punc- 
 tures are nearly 0-04""" in diameter ; the striie in the hroadest part of 
 the elytron are 0-2'""' apart, the width of the elytron 1-7""", and it.s 
 length S-S"""'. 
 
 The species differs from /•'. cdlci'dtits in the slight ly more rapid and 
 a]ncal attenuation of the elytra, the sironifer striation, shallower liut more 
 dense punctuation, and the smaller hair pits ; from /•'. huruii in its darker 
 colour, the stronger striation. shallower, denser and more rugulose [iiino- 
 tuation : and from /•'. /i(i(lii)>: in the broader and more suddenly narrowed 
 elytra, more distinct striation. and much luoie distinct punctuation.

 This species of I'latvnus is very diflerent from those described above 
 from the same deposits, and does not fall into the peculiar group which 
 they form. It belongs rather in the near vicinity of /'. e»^.v//;,v,'/,.v DeJ. 
 The sin.de elytron, which is a fragment oidy, but which representsa specie.s 
 apparenUv fully as large as this, has a very Hat st.rfacN with cars,, and 
 rather deeply impressed stria- very different from /'. ,..>,;,h,;,ll ,s, without 
 punctures, so far as can easily he seen on the upper surface, though they

 sigillarian stumps in Nova Scotia, and wliich \mi'i\\\vx\ XyhiliiitH: HhiUlnruc 
 Nearly twenty years ai,'o he kindly submitted to my examination all the

 United States ■[■ descri I )t ions were yiveii <)f live species and two j;enera 
 Xylol)iu.s and Aichiidu.s, of myriapods founfl therein. Since then Archiulus 
 has been found in other American Carboniferous deposits and X\ lobius in 
 the coal measures of luiropo. 
 
 By the aid of a 1,'rant from the Itoyal Society of London, Sir William 
 afterwards made a further .search anionLC the sii,'illai'ian trees in Nova 
 Scotia and placed in my hands the remains oi the articulates then found, 
 upon which I made a brief report some ten year.s a;;o in connection with 
 his own. X but until now have been unable to complete mv studv of them. 
 
 The fragments, for such they all are, which were .sent to me for exami- 
 nation, consist almost exclusively of myiiapodal I'emains. ■jften of sinirle 
 segments only, ami -ciKM-ally in a more or less cr'ushed, llattened, and dis- 
 torted condition. All the sjiecies formerly .separated in mv first studv <jf 
 remains from these stumps <iccur in the ])reseiit collection, but vcrv little 
 additional iniorniation can lie j;ained from them. Such as it is it will be 
 found below. A few specimens of diflerent species exhibit the marks 
 which were formerly interpr(!ted as the openini; of the stink-glands, fora- 
 miiui repugnatoria, connnon in recent myriapods, but th(;se arc now pre- 
 sumed to be the casts of the bases of spines ; in no i-ase ha\t' the spines

 Much cri'(lit is due to .Mr. Scudder for the caic and skill with which he 
 has worked up the fraL;inentary remains from the contents of t he erect 
 si^'illariic of the .loLti^ins coal measures. Willi reference to the condition 
 of the s|iecimeiis it is to he oliserved that these remains are found in the 
 matter lillinu the liases nf hollow trees originally open to t he air, into 
 which small ani]ihiliians have fallen and iiavc possilily lived in these siii- 
 <,'ular ]irisons for some time. Hence no douht in jiart the frau;iiieiitary 
 condition of the iinriapodal and arachnidan remains. Indeed seniiu'iits 
 of millipedes and remains of insects have lieen fouixi in ( he coprolit ic 
 matter associated with the reptilian hones, .so that it is i|uite likely that 
 the arthropods have heen pulled to pieci'sand paitially devoured hy their 
 iimjiliihian comjianions in misforlune. In addition to this the loose and 
 une(|ual character of the material lillinu- the lower jiarl of t he hollow trees 
 has caused iiiui'h crushin;,' and distortion of the (lexilile crusts of these 
 creatures, and has reiidi'ied it ditliciilt t<i olitain from the mass even such 
 fragments as those I was alile tosuhmit to Mr. iSeudder's inspection. < )n 
 the othi'i' hand it is a rare chance to lind even such frai,'iiients preserved 
 lit all, and hut for the accident of the mode of decay and entonihmeiit of 
 these trees, we ini!;hl have known nothinj;' of these curious and ancient, 
 aii'direathers of the coal formation of Nova Scotia. 
 
 Tlie identiliiation of remains of scorpions is fuitlier of interest from tho 
 light which it easts on one at least of the uses of tiie scaly armour of the 
 smaller ampliihians of the coal measures. They may, as Mr. Scudder has 
 alreadv sii^'uested, have re(|uired |ir()tection from tlie act ive and venomous 
 arachniilaiis with which they had to compete, or on which they may in 
 some cases have fed.
