THE collection of Tortoises and C rocodiles in the British Museum

was that part of the herpetological ser ies to which the late Dr . Graypaid special and unremitted attention . Besides numerous paperswhich appeared in variou s periodicals , he prepared the followingCatalogues for publ ication by the Trustees

The collections made during the Transit of Venu s Expedition

and the opportun e visits , in the year 1875 , of British vessels to theGalapagos I slands furn ished unequalled materials for the thoroughexamination of a group of Tortoises which previously had not been

well understood . This examination was undertaken by myself, and

the results were published by the Tru stees in6 . The Gigantic Land - Tortoises (Living and Extinct) . 1877.

iv PREFAC E .

In these works,however

,there i s great divergence as to the

c lassificat ion and nomenclature of the specimens,Dr . Gray , especi

ally after he had commenced to study the configu rati on of the

skulls , having i ntroduced at su ccessive periods numerou s changes

wh ich cannot be maintained in the present state of ou r knowledge .

Also the Hand - List of 1873 has become antiquated, not only onaccount of the addit ions of more recent years , but also in consequ enceof the elimination of numerous duplicates which were transferred toother public Museums .

Thu s it appeared desirable to prepare another issue of this

Catalogu e on the plan of the new series of descriptive Cataloguesof the Zoological Collections . Numerou s woodcuts have been

introduced , chiefly with the obj ect of illustrating the principle sadopted in the c lass ification ; all are taken from Specimens in the

Museum , but many have already appeared in Dr . Gray’s papers in

the ‘ P roceedings of th e Zoological Society ,’and are reproduced

here by the kind permission of the Council of that Society .

INTRODUC TI ON.

IN striking contrast w ith what has occurred in other groups of lowerVertebrates , the increase of known species of Chelonians has beenvery slight within the last twenty y ears . In fac t , the presentvolume records a considerably smaller number of specie s than did thelast- published treatise , vi z . Dr . Gray

’s Supplement to the Catalogu eof Shield R eptiles , in 1870. This decrease is o f cou rse due to thedifferent v iews held by the writers as to what deserve to constitu tespecific characters

,and also

,I tru st

,to a better understanding, at

the present day, of the amount of variation within given formBut the fact that hardly 20 val id spec ies have been discovered sin < ethe close of Dr . Gray

’s labours shows that our knowledge of theexisting Chelonians is far nearer completion than that of any OtlIt I'

group of R eptiles,Crocodiles excepted .

Though deficient in novelties ,— not a s ingle new species or genusi s established

,—I tru st that the present account will prove of interest

for the thorough revision which h igher and lower groups haveundergone

, and for the information it contains on the osteologicalcharacters , which have hitherto been much neglected . Figu res o fthe skulls and shells (stripped of the epidermal shields , and showing the arrangement of the latter as well as of the underlying bonyplate s at ) are given for the princ ipal genera . Although imperfectas regards the su tu res and other detai ls , the woodcu t s of the sku llsgiven by Dr . Gray in some of hi s papers are still u sefu l to showthe shape and general characters of the skulls

,and therefore have

been reproduced in the present volume . As to the original figu res ,which have been e xecuted with great care , I hope they will provewelcome to palmontologists as well as to zoologists .

C rosses have been inserted in these figures to indicate the po sution o f the

axillary and inguina l bu ttresses of th e plastron ,which anchy lose w ith the lower

su rface of the carapace .

The number of spec ies of Chelonians,regarded as well established ,

amounts to The Collect ion contains representatives ofthe number of spec imens be ing1 665 . Gray

’s Hand—li st,

’ issued in1873, records 107 species and 1371 specimens . During the preparation o i this Catalogue the series of skeletons has been greatlyenlarged .

23 species of Emydosaurians appear to be well established18 of whi ch are represented in the Collection by 236 specimens .

Since the publication of the ‘Hand - l ist,

’in which 23 spec ies and

304 specimens are enumerated , a number of defective or duplicatespec imens have been el iminated ; this accounts for the de creasein the number of spec imens

,as well as the fact that

,through over

s ight,the same spec imens were occasionally put down in the

Hand—lis t ’ under differen t spec ific h eadings,and e xtracted skull s

,of all known R eptilia

in many points they approach the Stegocephal ian Batrach ians ;i t i s poss ible that the common ancestors of the Chelon ia, theP les iosauria

The cervicals are short and similar to those of the Chelonidae . All

th e dorsal r ibs e xcept the last articulate with the neural arch and

two centra the first and tenth ribs are short . The caudal vertebrmare procoelous . Chevron bones are absent .The dorsal shield cons ists of a mosaic of extremely numerou s

polygonal bony plates of u nequal s iz e , the largest forming sevenlongi tudinal kcels or ridges ; i t i s produced in to a pointed supracaudal portion , which covers the tail . In the y oung the dorsalsh ield i s soft and leathery . Between the sh ield and the last cerv icalvertebra a bone is present wh i ch i s the homologue of the nuchal ofother Chelonians .The ventral sh ield is similar to and continuou s with the dorsal ,

and l ikewise bears r idges o f enlarged tuber cles ; in the young bothsh ields are ex tremely sim i lar , but , w ith age , th ey d iffer in the ventralremain ing soft

,only the tubercles of the longi tudinal ridges and

a few others being bony . There i s an underly ing annulus of slenderbones , eigh t in number— the plastral elements— viz . the ep iplastra,the hyoplastra, the hypop lastra, and the xiphiplastra ; an entoplastron or interclavi cle i s absent .The skull bears a certain resemblance to that of C'helone, wh i ch

is,however

,l im ited to the shape and the general constitu t ion of the

temporal roof ; in the absence of the column - like processes of theparietal s descend ing to the pterygoids in front of the supraoccipitaland the prootics, and in the opisthoti c not com ing in contact w iththe squamosal , it differs from that of all other Chelonians .The external bony nostr i l is very large and situated entirely upon

the upper su rface of the skull,in front of the orbits ; the choanze

are qu ite anterior , the nasal duct being nearly vertical , and are

separated by the vomer , wh ich also separates the palatines . The

praemaxillaries are d is tinct ; the praefrontals , wh ich j oin the postfrontal s

,form a very shor t sutu re in front of the frontals . In one

of the adu lt sku l ls in the Briti sh Mu seum,the lachrymals are nearly

completely separated from the maxillaries but this i s merely an

ind ividual pecu liarity . The parietals entirely or nearly ent irelycover the supraoccipital ; they form a long su ture w ith the postfrontals , and a short one with the squamosals . The lower borderof the pos tfrontal j oin s the jugal and the squamosal

,and

,contrary

to what exists in the Chelon idae,is separated from the quadratojugal

by th e two latter bones . The quadrate bone is a good deal w i thi nthe ou ter border of the sku ll , and separates the op isthoti c fromthe squamosal ; the ear - chambers are open behind . The foramenmagnum , which is deepe r than broad, i s bordered by the basi as

well as by the supra and ex occipitals . The pterygoids are smallerthan in any other Chelon ian ; they are nearly entirely separatedfrom each other by the large basi sphenoid , which ex tends forwardsas far as the posterior borders of the orbits , and widely separatedfrom the max i llarie s by the palatines ; their lateral borders are

n early straight , and withou t “ ectopterygoid”processes : in front

,

they are in contact with the large palatines,beh ind with the

quadrate and the basioccipital . The mandible has the same strue

The hyo id (accord ing to Gervais) lacks the anter io rornua and the posterior are oss ified prox imally the body i s oss ifi edn its posterior half, and a small os s ification i s present on each side11 front of the cerato - hyals , which are large and bo ny .

The following is a bri ef sketch of the O steology of the Group .

DORSAL VERTEBRAL C erium: AND Gu nm en — There are ten dorsalvertebrae , the first and last of which have no share in the formation ofthe dorsal shield . The first has a short depressed centrum

,concave

anteriorly , with strong praez ygapophyses articulating with the postzygapophyses of the last cervical ; it bears a short rib anteriorly ,which. i s connected with the second rib

,and, in a few genera

(Kachuga , B atayur , Gallagu r, B a rdella) , also with the as cending

12 CRYP TODIRA.

ax illary buttress of th e plastron th is first rib is considerably moreelongate in the Chelydridae . From the second to the eighth vertebra inclus ive the centra, wh ich have flattened art iculary faces ,are connected by suture w i th the neural arches , wh ich expand intobony (neural) plates alternating w ith the centra, and w i th strongr ibs which

,at a short d istance from the i r attachment (between

centrum and arch), expand into large bony (costal) plates sutu rallyuni ted with the neu ral plates . The neural spine may be low orobsolete

,or more elevated , in wh ich case i t is reduced to a narrow

septum pierced with fontanelle s ; the latter being special to adu ltspecimens of the genus Testa clo. The capitular ex tremity of thesecond rib articulates between the first and second centra, and s o do,as a rule , the th i rd and fourth ; but the follow ing generally sh iftback so as to art i cu late with the m iddl e of the posterior centre . In

very old specimens it not unfrequ ently happens that the cos tal“eapitula

”become atroph ied or d isappear altogether . The tenthvertebra forms the counterpart of the firs t : the centrum i s veryshort

,with a posterior condyle , and a shor t r ib wh i ch may (in

C'helyelra and P la tysternam) abut on the eighth r ib in the samemanner as the firs t does on the second ; but , as a rule , it d ifferslittle in appearance from the penu ltimate do rsal and the foll ow ingsacral . W ith the ex ception of the first and hindermost, the centraare l onger than broad : they may be flattened inferiorly (secondvertebra of most Emydines , second to fourth or fifth of Chelydridae) ,feebly compressed , or strongly compressed and forming a keel (Derma temys, B a tagu r , Chrysemys , Testudo).In front o f the series of neu ral plates is a large plate

,the nu chal

,

situated above the first dorsal vertebra : th is plate , wh ich is presentin all Chelon ians

,is a carti lage bone , developed simultaneou sly w ith

the neural plates ; the fact that i t i s connected , by l igament , w iththe last cervical vertebra, and that it assumes on each side

,in the

C helydridze , the form of a rib,suggests the poss ibil i ty of its repre

senting,in part at least , the mod ified r ibs of the last cervical . Su ch

rib—like processes are als o present,well developed in the young and

shorter in the adult , in the Dermatemydida} and C inosternidae,

underlying the firs t or first two marginals ; in Uhelyelra and lila

creclemmys the r ib—l ike process extends to below the third marg inaland abu ts on the d istal end of the first costal . A mere indi cationof th i s process i s found in some young specimens of Emys orbicu lar isand other Emydines . The nu chal i s si x—sided and broader thanlong ”F.

There are normally eight neural plates . In a few genera,how

ever (Dcrmatemys , S tanrotyp us, Ginosternnm , Gis tndo), the series isreduced by one to three of the h indermost , and the correspondinglast or last two or three pairs of costal plates meet in a su ture on

the median line . In a specimen of C inos ternum a lboy ula rc, the firs tneural plate is also absent . The shape o f the neu ral plates affordsgood gener ic characters . They may be tetra hexa or octagonalthey may be all s imi lar in shape (hexagonal), or hexagonal plate smay al ternate w ith octagonal

,or tetragonal w i th octagonal (e . g .

Testado) . W hen hexagonal , thei r lateral sides may be of equal o rsubequal leng th (c . y . some Chelon idae) , or the ant ero - lateral (e . g .

Emys) or the postero - lateral (e . g . Uyclemys) the shorter ; the hindermost plates are as a general ru le short - sided in front ; the first i s

,

w i th few exceptions,tetragonal . I t not unfrequently happens for

one or more of the neural plates to Split up into two or three , or fortwo to amalgamate into one

,bu t such are u sually eas ily re cogni zed

as anomalies .The costal plates number eight on each side In the new ly

hatched young they are s carcely developed , and the ribs do not comeinto contact with one another ; ossificat ion starts a short d istancefrom the neural plate and seen works up towards the latter bu t i ttakes some considerable time until it reaches the d i stal extremity , astage which i s attained bu t late in life in C hely clra and lilacro

clemmys , and very late or perhaps never in the marine Turtles . In

B a tayur small fontan elles pers ist between the marginals and costalsin specimens which have nearly attained full size . As a rule

,the

carapace of land Tortoises os sifies more rapidly than that of freshw ater . The d istal extremity of the rib pers i sts as a free pointfitting into a corresponding socket in the marginal plate . The firstcostal plate is constantly the broadest (perpendi cularly to the axis),the last the smalles t ; in Oinosternnm the latt er i s unu sually smalland destitute of the distal point . In Testaclo

,Homop us , and Oin ixy s ,

and to a lesser degree in a few freshwater Tortoises,especially old

individual s,these plates are un equal in width

,alternately widen ing

proximally and narrowing dista lly .

Continu ing the series of the neu ral plates are two to fou r azygou smembrane bones termed the pygal plates , the last of which , in shapeand posit ion , forms part of the marginal ser ie s ; thi s distinction i smost obv iou s in immatu re Chelonidm,

the azygou s marginal beingseparated from the true pygals by an interspace .

In Tha lassochelys u sually and in Ohelone ex ceptionally , the lastpai r of costals meets on the middle l ine , between the last neu ral andthe anterior pygal , of which two or three are present beside s theazy gou s marginal .In add ition to the azygous posterior marginal , there are eleven

(exceptionally twelve) marginal plates on each side,ex cept in

S taurotyp us and Ginosternum ,which have only t en .

P LASTRON .~— The plastron is composed of nine bones “

N ine or ten in some fossi l marine form s .

side, between the hyo and the hypop lastron .

entoplastron, and , on each side, an epiplastron, a hyoplastron , a

hypoplas tron , and a xiphiplastron. The epiplastra may be regardedas the homologues of the clavicles , the entoplastron of the interclavicle

,and the other elements as a mod ification of the Stegoce

phal ian and lthynchocephalian abdominal ribs .” The entoplastroni s absent in the C inosternidae, even at b irth . In the early stage ofl i fe

,the shape of the ep iplastra and entoplastron are high ly sug

gestive of their homologues in other R ept iles and Stegocephalians,

and the paired abdominal bones are separated by wide fontanelles .This embryoni c condi tion is retained until late in life in the Chelydridac and throughout in the Chelonidae

,whilst in all other recent

Cryptodira the plastron forms in the adult a solid shield,which may

be divided into two or three portions by the presence of one or twotransverse ligamentous hinges, as in C istuclo, Emys , Cyclemys, andC inosternum . I t i s well to state

,for the fact has often been over

looked,or even denied , that th is h inge i s developed with age , the

more distin ct the o lder the specimen it is absent,or very ind istinct ,

in qu ite young specimens . In the adult of most genera the byeand hypoplastra are united with the marginal plates by suture ; ina few (C istuclo, Emys, Cyclemys, P la tystern

um) they are narrowlyseparated from the latter by l igament, the plastron being movableupon the carapace or the ou ter border of these bones form digitat edentations , wh i ch may either arti culate by gomphosis with themarginals (Chelydridae) or be entirely free (Chelonidee ) . The spacebetween the body of the plastron and the marginals is called thebridge ; it - is particularly short or absent in those Testudinidae inwh i ch the plastron is movable , and long and narrow in these forms(Chelydridae and S taurotyp us) in which the plastron is particularlysmall , the whole sh ield be ing cru ciform . In su ch Testudinidae as

have the plastron su turally un ited w ith the carapace,the hyo and

hypoplastron each send up a process , respectively termed the axillaryand ingu inal buttress , wh ich anchylose either with the inner surfaceof th e marginals or w ith the costals ; these buttresses are least developed in the land Tortoises and most in the Testudinidm frequ entingdeep water (B a tayur, Qa haya , C allayur , and Harclella), in whichgenera they form very large septa nearly reaching the vertebralregion and forming two lateral chambers occupied by the lungs ,which are particularly developed in correlation with the divingpowers .In the embryonic stage the entoplastron or interclavicle is con

stantly longer than broad, rhomboidal or T - shaped, terminatingposteriorly in a sharp point which persists , as a more or less elongatespine

,on the inner surface of the plastron

,in the adult of all Tes

tudinidae except Cyclemys, Geoemyda , and N icoria , in wh ich it i susually total ly absent . The entoplastron is dagger - shaped in C'lwlonemydas . The shape and connections of the plastral bones in newlyhatched Cryptodira vary considerably according to the genera .

The hyoplastra are widely separated from the hyp oplastra in theland Tortoises , and in contact in the aqua ti c

are proceelous ,ex cept in the C helydridze and l’latysternidze ; in C kc]ydm and

illucroclemmg/s the two or three anterior are procoelous,the next

biconvex,the rest opisthocoelou s in P lu g/sternum the last ten are

again procoelou s . Transverse processes or cestoids are present on

most of the v ertebrae and connected with the centrum and the

arch . Neural sp ines are not developed . Chevron bones are absent,

SKULL — The skul l of all Cryptodira i s comparatively very convex .

mostly so in the Chelonidae and terrestr ial Testudinidze , least in theC helydrida) . The deeper the skull the larger the orbits how ever ,in the C helonidm the orb it s , wh i ch are enormou s in the y oung and

half- grown , are comparati vely small in old age . The orb it is comple tely encircled by fou r o r five bones , viz . the max i llary , the przefrontal (the frontal), the postfrontal , and the jugal ; in P la tysternumalone the jugal is excluded , and, the praefrontal forming a suturew ith the postfrontal , only three bones enter the orb i t . The bonyexternal nostril is s ingle , bounded by the preemax illaries , which are

constantly di stinct , the max i llaries , and the pracfrontals th e fron tal sand the parietals are also d i stinct . The latter bones send down a

prolongat ion to th e pterygoid , from which it is u sually separated bya small scale - l ike bone , the homologu e of the columella or epipterygoid . The postfrontals are large in most genera , small and forminga narrow postorbital arch in most land Tortoi ses

,especially in P yx is ,

in which i t i s extremely slender ; this postorbi tal arch i s comparatively broad in o ther Testudinidae , and in the Dermatemy didae and

C inostcrnidae ; and in the Chelydr idae, P latysternidze , and Chelonidmthe postfrontal unite s in a long suture w i th the parietal

or greater part of the temple being covered by a bony roof.The cranial arches of other Monimostylicate R eptiles

,viz .

the postfronto—squamosal, the quadrate—jugs ] , and the parieto—squamosal

,are all three represented only in the C helonidze , in wh i ch the

temporal roof reaches its greatest development . In all other C ryptodira the parietal i s widely separated from the squamosal . In

some genera (Chelydra ,Illac'

roclemmg/s , P la tysternum , Erin/3, Chrysemys , B ellia

,Ma lacoclemmys , Ocadia ) the two lateral arches are

developed,though never to su ch a degree as in the Cryptodiran

Batagurs ; they are very short in P elomedu sa and S ternothcerus ,

and in the adult of the latter genu s , in wh ich the front plastrallobe i s movable , in qu ite a vestigial cond ition, as in the Cryptod iran genera Emys and C istudo . A more or less developed not ch

,

or canal,i s present in the axillary and ingu inal buttresses of the

plastron ,at their junction w ith the marginals .

C snvreAL V s nrs snm.— The presence of well - developed trans

verse processes , s i tuated behind the vertical of the p raez ygapophyses ,and the absence of any ginglymoid articu lations, distinguish the

cervi cal vertebra) of the P leurod ira . I t is also very frequentlythe case that the elements of the first vertebra unite into a s inglebone the hypapophysi s and the centrum (odonto id process) remain,however

,dist inct in P odoenemis, Emydu ra , and E lseya ,

and I havealso found them so in Hyd ra sp is h ilarii . The mode of art iculationof the cerv i cal vertebrm is diagnostic of the fam i lies thus

,in the

P elomedusidae, the second only i s biconvex , the follow ing being

concave - convex ; in the C helydidze , the second , th i rd , and fou rthare convexo—concave

,the fifth biconvex , the sixth concave - convex

,

the seventh biconcave,and the eighth biconvex .

CAUDAL VERTEBRE .— They are proceelou s and provided w i th well

developed transverse processes ; the number i s u sual ly 1 6 to 18 ;21 in P odoonemis exp ansa , 25 in Emydura ma equar ice . Chevronbones are absent .SKULL — The skull is mu ch depressed

,most so in C helys, the extra

ordinary fiatness of wh ich gives it the appearance of having beencru shed

,leas t in P odoonem is . The orb i t i s bou nded by the max

illary , the praefrontal, the jugal, and (except Chelys) the frontal .The praemaxillaries , wh ich are fu sed to a s ingle bone in C helys

alone,are well developed and bound the nasal open ing . Nasal

bones are distinct from the prmfrontals in all Chelydidae ex ceptC helys The frontal s and the parietals are distinct, the latte rbones being connected with the palate by descend ing processes . In

the Chelydidae the frontals are produced forwards,between the

praefrentals , to the nasal s , or to the nasal opening . A completebony temporal roof i s present only in P odoonemis

,and its constitu

tion differs greatly from that obtained in the Cryptodira ; the postfrontal is comparatively small

, and the pari etal forms a long su tu rewith the j ugal and the quadratojugal . In the other P elomedu sidaethere is a well—developed zygomat ic arch

,formed by the postfrontal,

the j ugal , and the quadrate - jugal,the latter element separat ing the

two former from the squamosal and the quadrate . In the Chelydidte

the z ygomatic arch is absent , but a parieto - squamosal arch ispresent in all genera save C helod ina . In P la temys , Emyd ura ,

E lseya , and , to a lesser extent, in Hydra sp is , the par ietals expandinto a supratemporal roof

,the side s of the temples remaining

,how

ever , unprotected .

The supraoccipital i s produced posteriorly beyond the parietal s,and

, together wi th the exoccipitals , bounds the foramen magnum ,

Bruhl and Hoffmann , however , represent them in that genus .

PLEURODIRA. 189

which , as in the other Chelonians , i s deeper than broad . In Sterne

tha rus and P elomedusa the bas ioccip ital is completely e xcludedfrom the occ ipital condyle .

The quadrate forms a complete frame to the tympanum ,rarely

with a very smal l interruption posteriorly , but a part of the outerand the whole o f the middle ear- chamber remain open

,the stapes

be ing entirely visib le from behind . The quadrate presents a largeconcav ity for the reception of the single condyle of the mandible ,and the pterygoids e x tend to the very edge of that concavity . Thequadrate forms a su ture with the basisphenoid , except in C helys, inwh i ch it is separated from the latte r by the prootie in P odoenenn

'

s

it j oins both the basisphenoid and the bas iocc ipital .The single vomer is well developed and separates the palatines

in the Chelydidae, rudimentary or absent in the P elomedusidae,in which the palatines form a median su ture . In C helys and

C helod ina , but not in the other P leu rodira,the praefrontals j oin

the palatines ; these genera thu s d iffer by the presence of a bonyseptum between the orbital and nasal cav i ties . The pterygoidsare ex tremely broad , j oin on the median line , and their outer bordersexpand into thin lateral wings , which in P odocnemis extend posteri orly as palatal lam inae d i stinct from the processes which j ointhe qu adrates . A more or less developed

,rolled up late ral proces s

i s present,which borders a deep canal leading into the orbital

cavity . As po inted out by R utimeyer, the pre sence of this canali s in correlation with the e x tent t o wh ich a postorbi tal bony septum ,

formed by the postfrontal , the jugal , and the palatine, i s developed ;the more complete the separation of the orbital cavity from the

temple,the larger the canal ; C helys stands , in th i s respect , at the

lower end of the serie s , the arrangement not being carried out mu chfurther than in the most thoroughly aqu ati c Tes tud inidae . In noneof the P leurodira do the pterygoids extend po steriorly beyond thequadrates in Chelys , Emydura , and Elseya they j o in the maxillaryanteriorly , whilst in the other genera they are separated from thelatter by the palat ine and jugal .The mandible arti culates w ith the sku l l by a large s ingle condyle ,

in which the posterior elements are u sually completely fused . A

symphy sial suture is present in the Chelydidae, at least in youngind ividuals .HYOI D ARCH .

— The hyoid is mu ch developed in the Chelydidae,especially in C helys , Hydromedusa , C helod ina , and Hydrasp is . Thebody is fu lly ossified, elongate , and hollowed out as a canal for thetrachea in the fou r above - named genera , there are fou r ossificationsan teriorly , with a membranou s space between them and the posterior, elongate, canal - like bone . Two pairs of ossified cornua are

present,the anterior the strongest . C helys has a pair of very large

bony entoglossals , forming together a T - shaped figure entoglossalbones are also present in Hydromedusa , but mu ch smaller and sub

cir cu lar in shape they are absent in Ckelodina and the other genera .

In the P elomedu sidae the hyoid is comparatively feebly developed ,more as in the Testudinidae . The body i s cartilaginou s and a singlepai r of ossified cornua are presen t, the posterior being cartilaginou s

1 90 PLEUROD IRA.

P EC TORAL Anon AND Fons L inn — The P elomedusidaa and

C helvd idae are in th i s respect very s im ilar to the Testudinidae ,ex cept that the humeru s i s less strongly curved , and the shape ofthe coraco id var ies w ithin w ider l imits ; thu s in C helys the latterbone w idens very cons iderably towards the ep i coraco id cartilage ,affe cting a sub tr iangular shape very s im i lar so that of the samebone in the Land - Torto ises ; in P oclocnemis, on the contrary , thebone i s very narrow and , apart from its be ing shorter in proportion ,

resemb les that of the C helonidm the other genera are intermediatebe tween the two extremes . The s tru cture of the hand does not

d iffer considerably from that of the freshwater Testudinidae ; thereare nine carpal elements , bu t the rad iale and centrale u sua lly fuse,and so do the two outer distal carpals in Emydura ; in the latte rgenus and in P oclocnemis there i s a pai r of add it ional small bones

,as

in many Emyds . The phalanges number 2 3 3 3 3,except in

P elomedu sa , in wh ich each finger has only two phalanges , the basaland the second being fused into one . The genu s C'arettochclys, asfar as can be judged from the figure published , appears to have a

manus very similar to that of the Marin e Turtles,the penu ltimate

phalanx of the second and third fingers be ing ex ceed ingly elongate ,and the th ird finger i s the longest only the two inner fingers are

prov ided with claws .

P ELV I S AND H IND LIMB .— All ex isting P leurodira agree in having

the pelvis sol idly uni ted with the carapace and the plastron . Theil ium is expanded at its dorsal extremity , u sually subtr iangu lar inhor i z ontal sect ion ,

and,in the adu lt

,bears no trace of sacral attach

ment in the P elomedu s idae it is an chylosed to the last and penultimate costal plates ; in Chelys , Hydromedusa , and t i 'nemys to thepygal in add ition to the two latte r ; and in Chelod ina , Hydrasp is ,P la temys , Emydu ra , and Elseya to the last costal and the pygal . The

pub i s i s anchylosed to the xiphiplastron on a comparat ively smal lsu rface , the extremity of the ou ter branch , the inner or symphysialbranch being perfectly free, slender , more or less d i lated toward sthe symphysi s and d irected forwards i t i s nearly parallel with bu twidely separated from the isch ium . The latter bone i s anchylosedto the x iphiplastron by its enti re lower surface , wh ich is di rectedobliquely forwards and forms a symphys i s w i th its fellow . W i ththe ex ception of C arettochelys , the hind limbs closely resemble thoseof the freshwater Cryptod ira . The tarsu s contains two bones inthe prox imal row

,a large inner (tibiale+ intermedium) and a

small outer the centrale remains dist inct in most gen era, presentingth i s pecu liar ity in C'heZg/s that i t extends to the inner border of thetarsu s

Donsxr. V ER TEBR AL COLUMN AND Gam m on — As in the Cryptodira,the dorsal vertebral column consists of ten vertebrae, the first and lastof wh i ch are free from the carapace and have small or vestigial freeribs the centra are flattened , w ith a more or les s d ist inc t ventralkeel . The first dorsal v ertebra articu lates w ith the last cerv i calmerely by its prae z ygapophyses . E igh t ribs con tribu te to the formation of th e dorsal d isk, bu t in the American species of Trionya'

,

wh i ch have bu t seven costal plates,th e last remains free ; the

vertebral attachmen t of all e xcept the latter is between two centra .

All the dorsal plates are s cu lptu red , p itted , vermiculate , o r granu late .

The neurals,the greater part of wh i ch are s i x - s ided

,with the

postero - lateral s ide the shortest, number generally seven or e igh t ;bu t they are much redu ced in number and in si z e in C yclanorbis ,in wh ich

,as in some P leu rod ira

,the co stal plates meet on the

med ian line betw een them . Except in some Tr ionyx ,the last or

each end overlaps the ex trem i ty of the rib of the second vertebra .

In Emyda , C yclanorbis , and C ycloderma,on the contrary, the ou ter

extrem i ties of the nu chal bon e are overlapped by th e first costalp late . P ygal s are absent

,and likew i se marginals connected with

P LASTRON .

— Th0 p lastron forms , as in the Mar ine Turtles and they oung of all Chelon ians

,an incomplete sh ield , a medi an vacu ity

be ing present throughout l ife between the lateral elements . These ,the hyo and hypoplastra , are jo ined by suture , or may even (inC yd oderma ,

Emyda ,and C yclanm bzs) be fu sed into a s ingle bone

as early as birth , although d ist inct i n the embryo 7‘

, but the ir 1nncrand outer borders form deep dentations

,and there i s no connection

w i th the dorsal sh ie ld . The x iph ip lastra j o in each other and the

hypoplastra by interlocked d ig itation s . The three other elements ,v iz . the epiplastra (clav icles) and the entoplastron (interclavicle) ,d iffer greatly from their homologues in other Chelonians , each ofth ese be ing angu lar or chevron - shaped

, th e three form ing togethera A or X - shaped figure the poster ior branch of each epiplastron isin contact w ith the entop lastron,

and separated by the extremity ofthe latter from the hyop lastron . Some or all of the plastral bonesdeve lop w ith age superfic ial rugose or s cu lptured plates , the so

called p lastral cal los ities,wh ich may extend cons iderably beyond

the limits of, and d iffer greatly in shape from ,the or iginal bones .

In Tr ionyx th ese plates are con stantly present on the hyo—hypoplastra , u sually on the x iph iplastra

,and m ore rarely , and as a ru le

only in fu lly adu lt spec imens , on the entoplastron in C ycloclerma ,Emyda ,

and C yclcm orbis,each bone has i ts s cu lptu red plate , and in

the latter genus th ere are a pair of addit ional s im i lar plates infront of the ep iplastra and often other

,smaller, independent ossifi

cat ions as w ell .CERV I C AL V ER TEBR EE .

mos t remarkable pecu l iarity res ides in the s tructure of the last ore igh th vertebra , the cen trum of wh ich term inates in a th in plate anddoes not arti cu late w ith the first dorsal ; the art i cu lation be ingmerely by means of the z ygapophyses , in such a way that the two

vertebrae form together an angle when the neck is stretched ou t,

,the absence of a

strong ridge on the inner alveolar su rface of the mand ible,and in

the presence , in the young , of fou r or more dorsal ocelli , which are ,

however, smaller than in T. hu rum .

The existing members of this O rder , the most highly organizedof all recent R eptilia

,cannot in my opin ion be d ivided into several

families . The fact that Tomistoma is altogether qu i te as mu chrelated to the long- snou ted Crocodile s as to the tru e Gavial isopposed to the separat ion of the Gavia lidae. The only constantimportant character between the Crocodiles and the Alligators i sthe increased number of mandibu lar t eeth in the latter, which isthe same as in Tomistoma . The well—known Cuv ierian character ofthe fou rth mandibu lar tooth fitting into a notch in Grocodilu s and

into a pit in A lligator is not absolutely d iagnostic , s ince , as alreadyobserved by Huxley , specimens of the short - snou ted C rocodilu sp alustris occu r which agree in th i s respect w ith the All igators,whilst, on the other hand , Cope has described a supposed All igator inwhi ch the fou rth tooth , on one s ide , fits into a notch . The shortsnou ted species of Grocodilus and Osteolcemus further agree w i th theAlligators in the mandibu lar teeth biting inwards of the maxillaryteeth instead of between them . Os teolcemus , although agreeingwith C rocod ilus in its dentit ion ,

stands in most other respects nearerthe All igators . A rather trifling character , recently pointed out byBau r

,viz . the absence of a more or les s developed po inted process

on the free border of the quadratojugal,d istingu ishes Alligator and

Notwithstanding all that has been written on the specific charactersof the Crocodiles , their dist inction and definition remains a matter ofconsiderable difficulty . Although the extreme fo rms , viz . G. ca lap kracta s and G. p alustris, differ very widely , the passage is so complete as to render even subgeneric divisions unadvisable . Thefollowing key will, I hope, suffice in most cases for the exactdetermination of the species, except with respect to newly bornspecimens, which can only be named by comparison with olderexamples .

The precise affinities of the foll ow ing Crocodile are uncertain,as

the or iginal descript ion does not give the number of the mandibularteeth ; and as

,in the uni que specimen upon wh ich the species is

founded , the fourth mandibular tooth on one s ide i s rece ived into a

notch as in tru e Crocodiles , and on the other into a pit,as in the

Alligators , i t i s d ifficu lt to say to wh ich group it belongs , althoughCope su spects i t s affinities to be rather more Alligatorial.

”It

also appears to me doubtfu l whether the absence o f the claw in thethird finger will prove a constant character .
