The chief object in preparing the present Catalogue has lieen to give at one xiev,- a 
complete account of all the species of the Shielded Reptiles {Cataphracta) no^x' in the 
British Museum, and of those species known to exist in other Cabinets, but which are at 
present desiderata in the Museum, to enable travellers, collectors and others to assist in 
completing the national collection. 

An indication of the separate locality of each specimen is given ; its sex and state are 
also noticed. 

The figures of the new species contained in the Museum Collection have loeen drawn on 
stone by Mr. Ford, so well known for the beauty and accuracy of his pencil. 


British Miisevm, December 1, ISoii. 






Body covered with square imbedded plates, generally 
forming a dorsal and ventral shield. The bones of the 
skull thick, united together into a hard mass, and including 
the quadrate bones and pterygoid processes. The tongue 
is short, affixed to the mouth, scarcely exsertible. The 
lungs are enveloped by a thick peritoneum, which performs 
the part and has the appearance of a diaphragm. The 
vent is round or linear, plaited. The male organ and va- 
gina are simple, the former having only a groove along its 
upper edge. Oviparous : the egg covered with a hard 
shell : the young, when hatched, having a large umbilical 
slit, which soon disappears.

The body enclosed in a case, formed of two shields 
united by their margins, and leaving only the head, ueck, 
limbs and tail free, which are covered with a scaly skin : 
the upper shield or thorax formed of the ribs more or less 
dilated on the sides, united together and adherent to the 
dorsal vertebrae by a toothed suture, preventing any mo- 

tion ; they are surrounded by a series of bones forming the 
edge of the shields : the lower shield or sternum is formed 
of four pair and a central anterior bone. The jaws are 
toothless, covered with a horny bill, rarely hid by fleshy 
lips : the upper bill covers the lower Uke a box. Eyes 
with distinct eyelids. The drum of the ear visible, nearly 
superficial. The legs short, thick. Tail conical. The 
vent is a circular hole.

I. Squamata. 1. Saura. 2. Ophidia. II. Cata- 
phracta. 3. Amphisbenee. 4. Chelonia. 5. Emydo- 
saura ; — 

and he points out the analogies between this order and 
those of Mammalia and Birds. 

Swainson, in Lardner's Cabinet Cyclopcedia (1839), 
p. 343, arranges these animals thus : — 

Order I. Emydosaures (Crocodiles). Ord. II. Che- 
LONiDES (Tortoises) . Fain. I. Chelidrid^e (Crocodile

Dr. Fitzinger (Systema Reptilium, p. 29, 1843) divides 
the Testudinata thus : — 

Order I. Tylopoda. Fam. I. Testudines. 1. Ci- 
nixys. 2. Chersina. 3. Testudo. Order II. Stegano- 
PODA. § 1. Rostrata. Fam. I. Emyd^. 1. Emys.

1. Chelonia. 2. Thalassochelys. Fam. II. Dermato- 
chelyd^. 1. Derma tochelys. 

F. I. C Mayer (System des Thierreichs, 189, 1849 ; 
Wiegmann's Arch. 1850, 67) arranges the Tylopoda or 
Chelonians thus : — 

1. Bsenodactyli (Testudo). 2. Eressodaetyli (Emys, 
Trionyx). 3. Pterodactyli (Chelonia). 

The upper shield or carapace is formed by the ribs (eight 
pairs), enlarged and united together and to the annular part 
of the dorsal vertebra by toothed sutures, so as to be im- 
moveable ; the lower shield or plastron is formed of the 
pieces which represent the chest bone (usually nine), and 
a circle of bones analogous to the sternal cartilages of qua- 
drupeds. The vertebrae of the neck and tail alone are 
moveable. The two long envelopes are immediately covered 
with skin or scales, and surround the muscles of the ex- 
tremity. — Ann. Phil. 1825. 

The bones of the sternum are in general united together 
into a single plate, and are often affixed to the margin b}' 
a toothed suture, but in the CistudcB they are united to 
it by a cartilaginous band allowing of a slight motion ; 
and sometimes, as in the Box Tortoise, the sternum is 
divided into two or three parts by one or two cross 
sutures, allowing the front or hinder lobe, or both, to 
move on the middle or fixed part. In the genus Che- 
lydra, and the families Trionyeidte and Cheloniadce, the 
sternal bones form a ring, leaving a cartilaginous space in 
the centre.

Wagler, Syst. 138 (1830). 

They are slow in their motions, eating vegetables and 


roots ; living in woods or fields in warm and temperate 
parts of the world. lu colder climates they burrow, and 
sleep during the winter. 

In the genus Testudo the sternum is quite solid, but in 
some specimens of T. inauritiana, T. marginata, and Ho- 
rmpns areolatus, the hinder lobe has been observed to be 
moveable. On this account Dr. Wagler has separated the 
former into a genus, under the name of Cherseus. But it 
may be only a peculiarity of the females when they are about 
to deposit their eggs, and will probably, when these animals 
have been more obser\'ed, be found common to the females 
of all the species. 

A. The last vertebral shield almost always as ^vide as the

This species differs in appearance according to the state 
of the surface of the shell. When perfect the surface is 
black, with small yellow impressed areolas to the plates 
surrounded with deep concentric grooves ; but the surface is 
often more or less worn, when the concentric furrows are 
destroyed, the surface becomes smooth, and the small 
areolas are obliterated. In this state it has been considered 
a distinct species. The hinder vertebral plate is large, as 
broad as the caudal, the hinder marginal and the half of 
the second hinder marginal plate. In one specimen, which 
has only eleven marginal plates on each side (the two liinder 
being imited ?), the hmder vertebral is as wide as the cau- 
dal and half the large hinder marginal plates. 


B. The last vertebral generally only as loide as the caudal 
and half of each of the hinder marginal shields. 
Confined to the Old World.

of T. Indica and T. planiceps of nearly the same dimen- 

Testudo Indica. — Skull high, convex ; forehead convex, 
rounded to the nose-cavity, broad between the eyes ; tem- 
ples flat behind ; cheeks small, four-sided ; edge of the jaw- 
between the nose-cavity and the mouth narrow and rounded. 
Nose-cavity oblong, nearly twice as high as broad, con- 
tracted on each side above. Palate broad, oblong, very 
deeply concave, and with concave converging sides in front. 
Sphenoid bone deeply concave beneath under the condyle ; 
lower jaws narrowed and rounded in front, not more than 
half as hieh as behind.

Testudo planiceps. — Skull much depressed, flat ; fore- 
head flat, with a rapid declivity towards the nose-cavity, 
narrow between the eyes ; temples produced, bent in be- 
hind ; cheeks large, subtrigonal ; edge of the jaws between 
the nose-cavity and the moutli high and erect. Nose-cavity 
nearly square, scarcely higher than broad, and very little 
contracted above. Palate narrow, nearly lozenge-shaped, 
truncated behind, rather deeply concave, with straiglit con- 
verging sides in front. Sphenoid bone flat beneath under 
the condyle ; lower jaw convex, erect in front and as high

After an examination of the specimens of the large Black 
Tortoise {T. Indica) in the various English and continental 
collections, including the specimens which had served 
Schweigger, Schlegel, Fitzinger, Dtimeril and Bibron, and 
others as the tvpe of the species, in the Catalogue of the 
Tortoises, &c. in the Collection of the British iNIuseum, I 
regarded them all as varieties of a single, very variable 
species, which had been scattered by man in different tropical 
parts of tlie globe. I see no cause to change this opinion 
with respect to the head above described and figured, even 
should it prove to be that of a black species, which is possible, 
as the black species is the only one known which has any 
affinity to it in point of size, and it is said to be from a shell 
of that colour. This skidl was sent to Haslar Hospital, and 
was said to have been taken from a specimen brought from 
the Galapagos Islands. 

The Black Tortoise of those Islands has been described 
by Dr. Harlan under the name of Testudo Elephantopus, 
but his figure and description so exactly agree with the 
adult Testudo Indica, and the specimen in the Gardens of 
the Zoological Society, brought from the Galapagos Islands, 
is so exactly similar to the specimens of Testudo Indica 
from the Mauritius, that I cannot think the usual black 
Galapagos Tortoise is difi'erent from that species, or like the 
skull here described under the name of T. planiceps. 

5. Testudo Horsfleldii. Horsfield's Tortoise. Tab. I. 

Shell oblong, rather depressed, pale, varied with blackish, 

especially upon the lower side ; the areola of the costal plates 

near their upper edge ; the gular plates elongate, triangular, 

longer than broad ; the anal plates broader than long, the 
hinder notch broad, triangular, the hinder marginal plates 
broad, with the nucleus on the centre of their margin ; the 
front edge of the fore arms with smaller scales than the 
hiuder ; the vent with two blunt spines on each side.

a. Young. India ; Affghanistan. Presented by the Hon. 
East India Company. 

This species is very like Testudo sulcata, but the shell is 
more depressed, the margin rather more produced and 
toothed, and the scales of the fore feet are small and un- 
equal, and those on the side of the vent are shorter and 
broader than in that species. The nuclei of the hinder 
marginal shields are central, while in T. sulcata they are on 
the hinder edge of the scales. 

It resembles T. grceca, but the three pairs of sternal plates 
are longer in comparison to their width than any specimens 
we have, and the nuclei of all the hinder marginal plates 
are on the hinder edge, and not in the centre. 

6. Testudo stellata. The Starred Tortoise.

The specimen of Testudo luteola (Baud. Rept. t. 25) 
in the Paris Museum is evidently a young shell of this spe- 
cies, without any shields. 

There is no difference in the colour or in the size of the 
areolEe of the three varieties ; the nuchal shield of the va- 
riety tentoria is sometimes reduced to a linear transverse 
band, and is very rarely quite deficient. 

Schlegel refers Testudo tentoria and Pyxis aranoides of 
Bell to this species {Fauna Japonica).

These shells vary considerably in external appearance. 
In some the caudal plate is broader and strongly bent in at 
the tip ; in others it is narrower and flat, or even sometimes 
slightly bent out at the tip. All the female and young 
specimens I have examined have this form ; I therefore 
consider it as a sexual character only. The caudal plate in 
both of these variations is often divided by a more or less 
distinct central longitudinal groove, which has been con- 
sidered as a specific character, but it varies greatly in 
distinctness in different specimens ; in some the margins 
over the hind limbs are more produced and reflexed than 



in others ; these appear to pass almost into T. marginata. 
This variet)' is figured by Schoejpff. t. 9. 

The hinder lobe of the sternum of the female is some- 
times moveable. 

Called Tartaruga at Rome, where they are sold in the 
market and eaten on fast days. 

In the College of Surgeons there is a very narrow and 
high variety, with the caudal plate spread out, and the 
margin dilated and reflexed. 

Schlegel refers T. marginata and T. Zolhafce as va- 
rieties of T. graca.

that species is often more or less produced.

Apt to vary in the number and form of the vertebral,

wanting, or reduced to a small triangular scale behind the 
angles of the marginal plates. 

Animal pale brown-black, strongly toothed ; head with 
small scales and a large six-sided occipital plate ; fore-leg 
with lanceolate tubercular scales ; tail short, conical ; cheeks 
covered with small scales. 

Testudo cafra and Testudo Juvencella, Daudin, of which 
only two very imperfect specimens exist in the Paris Mu- 
seum, are probably varieties of one of these species. The 
first has fifteen discal and the latter very convex dorsal

Cinothorax (Bellianus), Fitz. Syst. Rept. 29 (1843). 

In the young the dorsal suture is scarcely observable, 
but then the genus can be distinguished by the large size 
of the inguinal plates ; the suture becomes more observable 



as the animal increases in age, unlike the Box Tortoises, 
where the moveable lobes of the sternum often become 
annhylosed in the older specimens. Cuvier, having seen 
only one specimen (Reff. Anim. ii. 10), considered this 
Structure as an accidental deformity, and Wagler by mistake 
savs it is the front part that is moveable. 

In a very perfect ^young specimen in the Museum, the 
third costal shield is divided obliquely across by a regular 
linear suture into two distinct plates, from the hinder part 
of the upper to the front part of the lower or outer edge. 

The number of the claws is liable to vary in the same

In some, perhaps in all the genera, the head of the 
males is larger and broader, the tail larger and longer, and 
more strongly clawed at the end, and the sternum more 
concave, as in the former family, than in the females. 

Dr. Harlan observes that the females of some species are 
more keeled than the males, but this distinction is very 
doubtful, and requires verification.

Sternum rather narrower than the cavity at each end ; the 
cross suture between the two sternal lobes in the middle of 
the long sterno-costal suture. 

c. Sternum divided by two cross sutures; central lobe attached 
to the thorax by a bony symphysis, covered by the end of the 
abdominal shields only; sternal plates II or 8; the axillary 
and inguinal plates large. Toes webbed. 

14. Kinosternon. Sternal plates 1 1 ; gular plates united ; humeral 

and pectoral distinct ; pectoral triangular. 

15. Aroinoclielys. Sternal plates 11 ; gular linear, rudimentary; 

pectoral broad, four-sided. 

16. Staurotypus. Sternal plates 8 ; gular, humeral and pectoral

B. Head and tail very large; sterno-costal symphysis covered 
with one or three peculiar plates. 

a. Sternum cross-like, acute before; sternal plates 10, with a 

broad one on each side, over the sides of the sternum. 

17. Cbelydi-a. Head depressed, covered with a soft skin. Shell 

with a single series of mai'ginal shields. 

18. Macroclemys. Head large, high, covered with symmetrical 

horny plates. Shell with a double series of marginal shields 
on each side.

These genera pass gradually one into the other, and the 
similarity in the form of the sternum between Platyster- 
non and Emys converts the series into a circle. The genus 
Cistudo appears to unite them to the Land Tortoises, while 
Chelydra has some affinities with certain of the Chelydce. 

A. Head and tail moderate ; sterno-costal suture simple.

* Pectoral plates small, short, triangular, lateral, far 


Animal luiknown. Shell rather depressed ; caudal plates 
double, separate. Sternum solid, broad, produced and 



slightly nicked in front, with onl}' five pair of broad shields ; 
the pectoral shields being short, subtriangular, only occu- 
pying the angle between the outer edge of the humeral and 
abdominal shields ; axillary shields small, inguinal larger ; 
the areola of the discal shield central. 

The depressed form and divided caudal plate induce me 
to place this genus in Emyda. It most resembles Testudo 
Gopher in appearance, but is at once known from that spe- 
cies and all the other genera of Testudinid^e, Emydce and 
Chelyd(B by the peculiar form of the pectoral plates, which 
at first sight might he mistaken for a very large inguinal 
plate, if that ]ilate were not also present. In this respect it 
somewhat resembles the genus Khwsternon, but tliere the 
plate is only narrow at the inner end and reaches nearly to 
the centre of the sternum. 

The various genera of Tesfiidinidce have the pectoral 
plates much smaller than the others, and perhaps the small 
size of the plate in this genus shows its affinity among the 
EmyditKB to that family ; and were it not for the regular 
division of the caudal and the form of the pectoral plates, 
it might be regarded as nearly allied to the very variable 
Testudo Indica.

Schlegel, in the Fauna Japonica, confounds Em^js cras-

this species, but they do not even belong to the same natural 
genus. It appears to be rave on the Continent, as it is 
wanting in the Paris and Leyden Museums. 

Latreille and Prince Bonaparte confound this species with 
Chelonura serpentina.

This genus contains the more terrestrial and solid-shelled 
Terrapens with webbed feet ; their head is more square and 
flat-topped than in their more aquatic congeners ; and they 
have the eyes on the side of the face. The skull is square, 
with a broad flat forehead ; the orbits being placed quite 
on the side of the head and not interrupting the outline of 
the forehead, as in the more aquatic Emydes. 

These animals are essentially aquatic, but often leave the 
water for months together. They are very active and

lateral ; lower jaw narrow. 

There is perhaps more than one species combined under 
this name, or the pattern of the marks on the young is 
subject to considerable variation, which can only be decided 
by the study of more specimens than we at present possess. 

Mr. Bell observes that the Testudo Eurojxsa is a species 
of Terrnpene ; if so, the name of it should be changed, as 
it is certainly the Emys of the ancients. — Gray, Ann. Phil.

tttt North American. 

Several of the American Terrapenes have the claws of 
the front feet much elongated, especially the three central 
ones ; but this does not appear to be a permanent character ; 
for it is found in some specimens, and not in others of the 
same species. 

It may be observed, that the North American species of 
this genus require to be revised and accurately compared, 
as their present descriptions and the figures which have 
hitherto been published of them are often very unsatis-

concentric set of rings or spots on each.

*** Back uniform. 



* The dorsal shields variegated or ringed ; the marginal 
shields ivith two half rings, the centre of the ring 
being on the suture. 

The system of colouring is most distinct in the young 
shell ; and as the animal grows, the position of the centres 
of the concentric rings or spots is considerably altered ; thus 
the spot which is central in the very young animal becomes 
more and more lateral as regards the shield it is under, as 
the animal increases in size. To define a species properly, 
it should be examined, compared, and described in all its 
stages of growth, wliich has as yet been the case with very 
few of the American Emydes. 

There are sometimes one and sometimes two centres 
of the spots or concentric rings under each of the dorsal 
shields ; but, in general, the centres of the spots in the mar- 
gin are placed on or near the suture between two marginal 
shields, so that a part of the same spots or set of rings is 
on two neighbourmg shields. 

The colouring matter which forms the spots or varie- 
gations on the shell, is situated in the skin under the 
shields. The marks are much more defined and regular 
in the young animal, and more distinct in the skin when 
the shields are removed, than when seen through the thicker 
shields of the older animal. The colouring matter appears 
to be much influenced by the health of the animal ; for 
specimens which are well marked often become less 
marked and almost uniformly coloured in confinement, 
rendering the distinction of specimens of shells which have 
died in confinement very difficult ; and in many cases the 
sternal shields themselves become thinner, and at length 
carious, which at once shows that the shell is in a diseased 
state, and should not be considered in its normal state of

on the others, while in E. scripta there is only a single dark 
spot on the hinder margin of that plate, surrounded with a 
single series of arched, dark, concentric lines ; the form of 
the streaks on the neck and the extension of the dark 
marks on the stemo-costal symphysis are also permanent

The indistinctness of the streak on this animal and marks 
on the shell may arise from the muddiness of the river, for 
the specimen was covered in several places with a coat of 
mud. The peculiar disposition of the colouring is to be 
seen when the shields of the back are removed from tlie 
skin. It may not be E. Troosfn of Holbrook, which is 
said to be a very depressed species. See No. 23.

a. Adult (shell only). 

The sternum may in the perfect specimen be more 
distinctly marked, as this example had evidently died in 
confinement, as proved by the carious state of the centre 
of the sternum. The colour is veiy much suffused in the 
hinder part, almost hiding the pattern of the paler marks, 
and the central dorsal shields are rubbed and worn, hiding 
the pattern in that part of the shell. The swollen form. 



the obscure rounded keel on the first, and the sharp keel 
on the two hinder vertebral keels, are very peculiar, and 
the manner in which the rings are marked on the marginal 
plates is unhke any of the other American Etmjdes I have 
seen, except E. pseudogeoyraphica and geof/raphica. 

The figure of Emys Mobilensis {Holhrook, N. A. Herpet. 
i. t. 9) somewhat rejjresents this species, as far as regards 
the distribution of the colours of the costal shields (they are 
more definite than in our specimen), but the pattern on 
the upper and under sides of the marginal shield is entirely 
unlike, as the rings or spots are represented as being on 
the suture, half the spots being on each shield, as in the 
more common form of American Emydes. But in this 
respect, Dr. Holbrook's artist is not to be depended on, as 
he represents Emys geographica distinctly, and pseudogeo- 
graphica indistinctly, as having the rings of the same form, 
which authentic specimens show to be an error. 

Dr. Holhrook represents the head, neck, throat and feet 
of Emys Mobilensis as having broad yellow hues, the two 
central throat hues being united near the chin. 

§§ The dark areola and ring are in the upper hinder mar- 
gin ofthefrst, and gradually lower in the second and 
third, so as to be in the lower hinder margin of the 
fourth or last costal shield, and on the hinder margin 
of all the vertebral plates. 

There is generally a smaller dark spot in the centre of 
the other rings, formed by the netted lines, as ou the front 
lower edge of the first and second costal, and on the sides 
of the vertebral plates. 

26. Emys geographica. The Geographic Emys. 

Shell ovate, convex, smooth, tubercularly keeled in front 
and slightly toothed behind, olive-brown, with black-edged 
anastomosing pale lines ; first and fifth vertebral plates 
broad, five-sided, rest broad, six-sided. Sternum yellow; 
shields blackish-edged ; under side of the marginal plates 
ohve, with rather concentric, black-edged, broad and narrow 
pale lines. Head and feet with numerous yellow lines, and 
a triangular yellow streak on each temple.

The Museum specimen is in a bad state ; it chiefly difi'ers 
from E. pseudogeograjihica in the keel not being nodose, 
the vertebral plates very broad and short, and in the pale 
reticulations being finer. 

It may be distinct from the E. geographica or mega- 
cephala of Holbrook (which is represented by the same 
figures) ; and perhajjs it would have been better to retain 
for it the name under which I first described it. 

Dr. Holbrook represents the head of E. geographica as 
large (that may be sexual), with numerous regular green 
lines, an oblong elongated spot on each side of the nape, 
and an eyed spot on each side of the throat, near the angle 
of the mouth. 

27. Emys pseudogeogi-aphica. The Sharp-b.^cked 

Shell elongate-ovate, nicked in front, toothed behind ; 
vertebral keel tubercular, very distinct, netted with nume-

the hinder edge of the costal and marginal shields, and 
three smaller spots on the vertebral plates. Sternum \el- 
low, darker clouded, darkest in the young. Head small, 
oval, brown, with numerous yellow Unes and a yellow sjiot 
on and across each temple.

In our adult and three young specimens there is a spot 
on each side of the nose, a streak commencing from the 
middle of the orbit, diverging to the sides of the nape, a 
spot on each side of the middle of that part, and a narrow 
streak on the temple from the upper and lower part of the 
back edge of the oibit, and the neck is marked with several 
narrow black lines on the sides. 

Mr. Bell's figure of the adult {Testudinata, t. 1) differs 
from these ui representing the superciliary bands as being 
united by a short transverse band in front.

Emys dorsalis (Spix, Test. Bras. 1 1 . t. 9. f. 1, 2) probably 
represents the young of this species, as the marks on the 
head agree with those on our specimen. This figure has 
been referred to E. scabra, but the form of the head bands, 
if they are correctly figured, at once separates it from that 

Head covered with a thin hard skin, oblong ; forehead 
rather convex. Eyes subsuperior. Beak naked ; upper 
with two small teeth in front ; lower beak extended behind, 
covering the rounded lower edge of the lower jaw. Fore 
legs covered with large transverse shields. Toes short, 
strong, shortly webbed, covered with hand-like scales above. 
Claws 5-4, compressed, arched, the three middle front 
often much elongated, subequal. Tail moderate. Shell 
depressed. Sternum solid, broad, truncated before and be- 
hind, affixed to the thorax by a bony symphysis covered 
at the end by the pectoral and abdominal shields ; axillary 
and inguinal plates moderate, distinct. Shield very thin, 
smooth ; the marginal plates with a subcentral marginal 
areola, surrounded with dark-edged concentric rings ; the 
humeral plate triangular ; the pectoral narrow, square.

These Tortoises may be seen in great numbers in ponds,

die in a very few days after being taken from the water.

M.Bibron observes, that he has seen several specimens of 
this species in the " different Loudon Museums ;" the only 
one that has occurred to me is the one above described. 

Dr. Uolbrook's figure of Emys Origonensis (t. 21), in 
the dentated margin, and in the colouring of the sternum, 
greatly resembles this species, but the back is rather differ- 
ently coloured, and the sternum is truncated behind. It 
is probably only an accidental variety. 

tft Toes slender, elongate, covered with small scales or 
nearly naked, very largely webbed; claws conical, 
scarcely curved. 

Head moderate, covered with a thin hard skin, ovate ; 
forehead convex. Eyes subsuperior. Chin flat, not 
bearded ; branches of the lower jaw dilated, flat, covered 
with a soft thin skin. Fore legs covered with band-like 
scales. Toes slender, rather elongate, covered with scales, 
or with a smooth skin, widely webbed to the end of the 
toes. Claws 5 '4, acute, rather compressed, straight or 
slightly curved. Tail moderate. Shell rather depressed. 
Sternum solid, truncated before, nicked behind, affixed to 
the thorax by a bony symphysis, covered by the end of the 
pectoral and abdominal shields ; axillary and inguinal plates 
moderate, distinct. 



This genus is chiefly distinguished from E?ni/s by the 
flattened under jaw and the small size of the lower beak, 
the under jaw being chiefly covered with a soft skin, and 
by the slenderness of the toes and the breadth of the web, 
which most resembles that of the genus Bafagttr. 

The annulated spot on the under surface of the marginal 
plate on all the species I have examined is on the suture, 
so as to occupy a portion of two ueighbouriug shields. 

* Jaws entire ; upper only slightly nicked in front. 

Vertebral plates with three longitudinal, oblong, annu- 
lated spots, sometimes interrupted, each part forming an 
eyed spot ; the costal plates with two or three animlated 
spots, the larger and principal one on the hinder margin 
sending out pale diverging tortuous lines which separate 
the spots and transversely divide the shield into halves. 

1. Pseiidemys concinna. The Neat Emys. 

Shell oblong, smooth, keelless, olive-brown, pale ringed 
and lined, with a pale streak across each costal shield, with 
several unequal-sized more or less oblong annulated spots 
on each shield ; margin with a pale central cross-band 
above, with an oblong sutural spot beneath ; sternum yel- 
low, clouded with black, especially near the suture of the 
plates. Head olive ; neck and feet yellow-lined, with a 
broad lateral streak from the back of each eye. Fore legs 
with two yellow streaks ; webs with a triangular yellow 
spot on the margin between each claw.

M. Leconte's figure, which is engraved by Dr. Holbrook, 
is a moderately good repiesentation of our younger speci- 
men. It chiefly differs in the marks on the shell being 
rather too regular and distinct, the streak on the head 
broader, and the toes are represented as covered with scales ; 
but both these and the claws show that it belongs to this

Skull oblong ; forehead convex, shelving towards the 
temples ; orbits large, rather close together, shelving up- 
wards, enabling the animal to see above it. 

Mr. Bell, in his Testudinata, beautifully figures several 
specimens from life, showing the variations in the colouring 
of the animal. The animal varies in intensity from pale 
grey to blackish, and the spots on the temples, nape, neck, 
limbs and tail vary in size and depth, and are sometimes 
joined together into lines, which are often symmetrical on 
the two sides of the head. 

" As an article of food it is much preferred to any other 
species, particularly when dug out of the marshes in a 
torpid state : immense numbers are annually brought to 
market. The males are small, and have the concentric 
striee more deeply impressed than the females." — Le- 

The very young specimens are about two inches long, 
pale brown ; shields with narrow concentric lines ; second, 
third, and front half of the fourth vertebral plate with a 
very broad rounded keel. Sternum brown-dotted ; plates 
pale-edged, with a line of spots on the front and hinder 
edse. Mus. Bell. 

A very young specimen in spirits in the Museum of 
the College of Surgeons, named " Testudo picta." The 
shell is pale brown ; each of the costal shields has two 
concentric very narrow rings near the margin, and an 
irregular ring in the centre, the continuity of which is 
often more or less interrupted. The vertebral plates have 
a similar double ring, but both the marginal and cen- 
tral ones are more irregular and mterrupted. The upper 
surfaces of the marginal plates are each marked with a 
single submarginal ring and a larger central spot. The 
sternal shields are brown-dotted, with a brown band near 
the margin of each. 

b. Sternum divided by a central cross suture, attached to 
the thorax by a ligamentous suture, covered by the 
end of the pectoral and abdominal shields ; sternal 
plates 1 2 ; axillary and inguinal plates very small.

Cuvier, Reg. Anim. ii. 11 (1817), ed. 2. ii. 12, adopts 
Daudin' s divisions. 

Merrem gives to the Tortues ti boites the generic name 
oi Terrapene (p. 27, &c.). 

Mr. Bell, Zool. Journ. ii. 302, 486 (1826), in his paper 
on the Box Tortoises, forms a subfamily of Emydida: for 
them under the name of Sternotherina, and refers to it the 
following genera : — 

I. KiNOSTERNON, Spix, Containing: 1. K. Shwianum. 
2. A', longicaudatum. 3. K. brevicaudatum. 4. K. Penn- 
sylvanicum. 5. K. Amboinense = Terrapene bicolor,Tp. 484. 
6. K. nigricans = Sternotherus Leaehianus. II. Ster- 
notherus, Bell, containing: 1. S. trifasciatus (t. 13). 
2. >S'. Leaehianus (t. 14), which is the same as K. nigricans. 
S.S.odoratus. 4. S.Boscii=KinostenionPennsylvanica; the 



same as Kinosternon, as regarded by Daudin. III. Terra-

mere varieties of T. Carolina. To these, at p. 484 of the 
same vohime, is added as a new species : 5. T. bicolor (t. 1 6), 
said to come from North America, but it proves to be the 
same as Einosternon Amboinense of the former paper.

The shell is so hard and the animal so strong, that it can 
easily walk with 60 lbs. on its back. Its food consists of 
fresh insects and the edible fungi, particularly the species 
of Clararia. Many persons are in the habit of keepmg 
them in their cellars, where they destroy snails, crickets, 
and other noxious insects. It may be questioned if they 
ever attempt, as has been said, to devour rats and mice ; 
they are not well formed for the pursuit of such active 
animals, who have too much sense to suffer themselves to 
be caught by so sluggish a hunter. The same may be said 
of the ridiculous stories of their catching and destroying 
snakes. — Leconte. 

" This species has been cited as an example of longevity 
among animals of the lower class : all tortoises are loug- 
lived, but the finding of an individual with a name and date 
engraved on its sternum jn-oves nothing ; the idle and foolish 
are fond of inscribing their names everywhere, and may as 
well antedate the time by half a century as state the true 
vear of their attempt at immortahty." — Leconte.

become obsolete with age, and the margms of the shell, 
particularly the hinder part, become revolute. — Cantor. 

Schlegel regards Eimjs castcmea, E. subitiger, Terrapene

Head ovate, covered, with a thin skin ; forehead rather 
convex. Eyes subsuperior. Legs strong, covered in front 
with thin, broad, band-like, transverse shields. Toes strong, 
covered with small scales above, webbed to the claws ; claws 
5 • 4, short, curved, acute. Tail moderate. Shell convex, 
solid, edge-toothed behind. Sternum rounded in front, 
truncated behind, narrower than the cavity, not covering 
the legs when contracted, with a distinct process on each 
side to form the symphysis. The cross suture between the 
anterior and posterior lobe in the middle of the long sterno- 
costal suture, so that both lobes are equally attached to the 
thorax. Asiatic. 

This genus has the same shield-like and well-webbed toes 
as Einys and Cuora, but differs from the latter in the ster- 
nal lobes being narrower than the opening of the thorax, so 
that, as in Emys, it does not cover the legs when they are 
contracted. This similarity has induced naturalists to place 
the species in the genus Emys, overlooking the fact of the 
lobes being mobile.

Dr. Cantor describes three very young specimens of a 
Tortoise (the largest being onlv 2^ inches long), which 
were taken on the sea-shore of Pinang, under the name of 
Tetraonyx affinis. The Malays assert that this Tortoise 
also inhabits estuaries and rivers in the Peninsula, and that 
it grows to a considerable size. The outline of the shell 
and its composing shields strikingly resemble the young of 
Cyclemys orbiculata,Me\\\ — Cat. Rept. Penins. C. 

There can be little doubt that the above were the young 
of this species, which often has only 4 claws on the feet.

/. Very young. Shell very thin, with the black spot only 
very indistinctly marked. 

They are called " Katong " by the Malays in the Penin- 
sula. The head and neck, shell, tail and feet of the adult 
living animal are dirty yellowish or greenish brown, which 
becomes paler on the sternum. The nuclei of the vertebral 
shields are slightly raised ; the costal shields are depressed, 
their sides sloping towards the nuclei, thus forming as it 
were a very shallow hexagonal basis. The front and hind 
margins are broadly revolute, their toothed appearance 
worn off. The sternum is slightly concave in the centre. 
The}- inhabit the valleys of Pinang, and in confinement they 
refused to eat, and were never observed to enter a tank. — 

e. Sternum divided by two cross sutures ; central /obe at- 
tached to the thorax /jy a bony symphysis, corered by 
the end of the abdominal shields only ; sternal plat es 
11 or S ; the axillary and inguinal plates large.

In the adult specimens from New Orleans in spirits the 
head is dark brown, with irregular white spots on the occi- 
put ; all of them have two broad dark-edged streaks from 
the back of the orbit, the upper extended along the side of 
the neck, the lower to the hinder end of the beak, and aa 
intermediate small pale spot on the tympanum ; these 
marks all become more obscure on the older specimens. 

The young specimens, with the same description of 
colouring and from the same locality, vary a little in the 
comparative width and form of the lobes of the sternum, 
even when they have the same form of tad, wliich is sup- 
posed to mark the sexes.

" This species is very voracious in its habits, and destroys 
great quantities of fish ; it is also more ferocious than any 
other, and will seize with violence at anything presented to 
it, and not let go its hold even when the head is separated 
from the body. The wound inflicted by its bite is very 
severe. It is much sought after as an article of food : when 
old the flesh is musky." — Leconte. ^

a. Shell: length 17; width 11. Sternum: length 12^ 
inches. From the Museum of the Zoological Society. 

The specimen, which is not quite full-grown, has much 
the external appearance of Phrynops Geoffroyii, and the 
general thinness of the scales of the Chelydidce ; but there 
is no appearance of any scar on the inner surface of the 
sternum for the attachment of the pelvis, and though the 
gular scale is worn and nearly obliterated, yet it is suf- 
ficiently distinct to show that it has no intergular plate. 

Emys Berardii of Dumeril's Catalogue of the Paris Mu- 
seum is perhaps intended for this species. It is thus 
described : — 

" Shell yellow-brown, irregular, rugose, with a multitude 
of small vermiculations ; elongate, suboval, narrowed above 
the fore legs, rather sinuous behind ; hinder part of back 
slightly keeled ; nuchal small, short ; first vertebral pro- 
duced in front. Chest yellow, entire in front, notched be- 
hind. Head uniform brown, flat, broad, rather large ; jaws 
toothed. Toes broad-webbed. Tail strong, rather long. 

"Hab. South America {Mawe) ; Vera Cruz {Berard)." 

This is more likely to be the case, as Mr. Fraser's note, 
in the Catalogue of the Museum of the Zoological Society, 
shows that M. Bibron must have examined it, and these 
authors give the habitat as " South America {Mawe)," in 
their account of the species. If this be the case, !M. Bibron 
must have changed the name after his return to Paris.

In the Annals of Philosophy for 1825, 1 formed a section 
oi Emys (***) for Emys longicollis — " Toes 4'4 ; sternum 
thirteen-scaled," — and remarked: " The plastron of the last 
subgenus is covered with thirteen scales, that is, six pair 
marginal, and an unequal-sided hexagonal one in the middle 
of the anterior lobe." I have only observed an approximating 
distribution of the plates in a species of Sternotherus ; all 
the other Emyda that I have seen have had only the six 
pair of marginal plates, the first pair sometimes soldered so 
as to form only eleven plates. 

Mr. Bell, after stating that the same number of sternal 
plates exists in Sternotherus Leachianus and the two 
species of Chelys (see Zool. Journ. iii. 512, 1838), over- 
looked the other anatomical characters which unite these 
genera, and made no proposal to unite them into a natural 

Dumeril and Bibron in their large work merely change 
the name of the family as given in my Synopsis.

The genus Sternothcerus of Mr. Bell {Zool. Journ. ii. 
305) is exactly synonymous with one of Daudin's sections 
of the Tortues ii holies, and contains species of the genera 
Cistudo, Kinosternon, and the present genus, Sternothcerus. 

Mr. Bell, in his second paper (Zool. Journ. iii. 515), 
gives as the type S. Leachianus, which is the same as 
Terrapene nigricans of his former paper {Zool. Journ. ii. 
305) ; — placing the genus with the other Box Tortoises in 
Finydid<E, between Terrapene (claiisa) and Kinosternon. 

In my Synopsis of Reptiles I defined the genus so as to 
confine it to the species similar to that type ; and Dumeril 
and Bibron, in their work, adopted my views. Wagler 
uses Pelusios for the same group. 

Wagler {Syst. Rept.) quotes Mr. Bell's first species, S. 
trifaseiatus, as the type of his genus.

six-sided, much longer than broad, the last subtriangular. 
Head broad, the parietal and crown plates united into 
one ; muzzle bluntly rounded ; the sternum broad, with the 
hinder portion scarcely contracted in front, the front much 
rounded ; the central gular plate broad ovate, angular be- 
hind ; two anterior marginal shields as wide as the front 
vertebral. Jaws dark-lined.

b. Adult shell. Vertebral plates square, rather longer than 

broad. West Africa ; Sierra Leone. 

This species is separated from iS. castaneus and S. sub- 
niger by the shape of the vertebral plates, which in these 
species are broad, sLx-sided ; in the S. castaneus they are 
nearly as broad as long, and in the .S'. subniger the third 
and fourth are broader than long, and the fourth is ovate 
and swollen behind. Perhaps they may all prove only to 
be varieties of the same species, or dependent on age.

short, conical, simple. Shell covered with a hard cartila- 
ginous skin, usually expanded and flexible on the edge, the 
ribs only vinited together and to the vertebrae above, sejia- 
rate below. Sternum formed of a ring of bones, covered 
with a continuous skin, and in the adults furnished with 
rough callosities on the prominent i)art. Pelvis only at- 
tached to the vertebrEe. Living in rivers and lakes in warm 
climates : often lying in the mud with the head only ex- 
posed : eating flesh, and rarely vegetables. Eggs spherical. 

The ribs become united together for a greater propor- 
tion of their length, and the sternal callosities appear and 
increase in size as the animal increases in age ; hence thev 
do not afford specific, much less generic characters.

Geofi'roy used as characters the existence and non-exist- 
ence and form of the anterior vertebral bone ; but all the 



species of Trionyx have an odd bone ("marginal piece," 
Geoff.) on the margin, which is only slightly developed in 
the young. Geoffrey's figure of T. Egyptiacus is from an 
adult ; T. svhplanvs and T. carinnlus from young speci- 
mens ; T. Javanicus from an imperfect one, as complete 
specimens of this species have this bone. 

Fitzinger has divided this family into the genera Trionyx 
(ffranosus), Aspidonectes (Javanicus), Platypeltis (Bron- 
gniartii and ferox), Pelodiscus (Sinensis and labiatus), 
Aniyda (snbplanus and muticus), according to the union 
and separation of the cervical bones and the ribs, and the 
rugosity and partial smoothness of the surface of the 
dorsal plates ; but these characters alter with the age of 
the animals, and they separate nearly allied species and 
those coming from the same countries.

black-striped ; lips yellow." . . . "This Water Tortoise is 
generally distributed in the lower part of the island, and is 
found in lakfs and tanks. Several we kept alive for 
months in a tub filled with fresh water, fed freely on ani- 
mal food, and also on bread and boiled rice. A large female 
laid three eggs, globular, about an inch in diameter, with 
a hard calcareous shell. This Tortoise too is put into wells 
to act the part of scavenger." It is called Kivi-Ibba in

I had divided the American from the Old World species, 
believing they had only seven ribs, but on re-examination I 
find they both have the same number of ribs. 

The species may l)e thus divided according to their osteo- 
logical characters, but they can only be used with certainty 
by those vpho have a series of specimens of different ages 
of each species before them. 

* First vertebral bone broad, crescent-shaped, early deve- 

loped ; episternal bones rather far apart at the base. 

f Callosities 2 ; dorsal disfi with two pits in front, one on 
each side of the first vertebra. 

1 . Trionyx Rafeht. 

ft Callosities 4 ; dorsal disk with two pits in front. 

2. T. Argus. 

ttt Callosities 4 ; dorsal disk without any pits in front. 

3. T. perocellatus. 4. T. Nilolicus. o. T. Gangeticus. 
6. T. ferox. 7. T. muticus. 

** First vertebral bone oblong, not developed until late in 
life ; episternal bones elongate, close together at their 
base. Callosities 4. 

8. Tyrse Javanicus. 9. T. carinifenis. 10. T. frenatus. 

They may be divided according to the colouring of the 
head and limbs, but these colours often disappear or become 
indistinct in the adult animal. 

* Head and limbs with subeqiial white spots.

The young of T. Niloticus, T. Gangeticus, T. Javanicus, 
T. frenatus and T. ferox have the spinose tubercles on the 
back in numerous parallel lines ; T. perocellatus has them 
in distant, rather irregular lines ; and Chiton Indica has 
close, isolated, I'ounded tubercles, very much crowded 
together on the nape ; the side and hinder part of the 
disk smooth.

and a narrow black streak from the lip through the 
eve and extended on the sides of the nape. Throat 
whitish, marbled with blackish. China. Dr. Berthold 
Seemann. Tab. XXXI. From Haslar Museum. 

This species differs from T. carinatus in wanting the 
regular series of tubercles forming a keel on the back of 
the dorsal disk. 

Mr. Seemann' s specimen has the markings on the head 
very like those of a young stuffed specimen of T. ferox 
from North America which we received from Mr. W. Smith ; 
but the streak from the back of the eye in the American 
species is double, that is to say, pale, with a black edge on 
each side. 

This species may always be known in the young state by 
the scattered and irregular distribution of the dorsal tu- 

3. Trionyx Gangeticus. The Kaarey. 
Olive, vermiculated with dark brown (when young, with

with a large yellow spot between the eyes and a similar 
one behind each eye ; neck, limbs, and posterior margin of 
the shell dark olive, with paler round spots. Shell olive, 
with black irregular Hues and four or five central ocelli, 
black in the centre, edged with red, round which a black 
ring. Sternum pale whitish olive."

lines. Shell light olive, vermiculated with blackish or 
dark oUve ; the four ocelli are present, but are altered in 
colour and shape ; the centre, instead of being black, is, 
like the rest of the surface, light ohve, vermiculated with 
black ; the red ring is changed to black, and the outer 
black one to light olive. The shape is changed from round 
to irregular olive. Adult {Testudo Chin, B. Hamilton,

b. Half-grown female (stuffed). It contained many full- 

sized eggs ; the sternal callosities are only very 
slightly developed. Singapore. Mr. M'allace's Col- 

This species is very like Bagonia subjjiana, but the head 
is smaller and brown-lined, and there are indications of 
four sternal tubercles. The ribs are narrower, and the 
ends of the ribs are nearer the front side of the dilated 
part, and not in the centre, as in our specimen of D. sub- 
plana. The rudiments of the sternal callosities are on each 
of the two lateral sternal bones, while in Bagonia thev are 
only found on the anterior pair. 

The young specimen was named Trionyx Javanicus by 
M. Bibron, but the head was then entirely contracted into 
the shell, so that only the tip of the nose could be seen. It 
differs from that species in the position of the dark streaks, 
and in their being much less distinctly marked.

Trionyx annulatus, ITled, Voy. Amer. Sept. iii. 242. 

Of all the animals of the familv of Chelomdes, they fur- 
nish the most delicious and nourishing food. — Leconte. 

M. Wagler separates Trionyx carinatus, Geoff., into a 
section of his genus Aspidonectes distinct from T. ferox, 
and he regards T. ferox, T. muticus and T. spiniferus as 
three species. — Syst. 134. 

e. Adult female. With a row of large spines in front of 
the disk. North America. Mr. W. Smith's Collec- 

f. Adult male. Back of shell deformed, very high, almost 

conical ; front edge of disk with a series of spines. 
North America. 

g. Half-grown (stuffed). Front of disk with very small 

spines. North America. Mr. W. Smith's Collection. 

In these three specimens (e, f y) there is a greater space 
between the inner ends of the lateral callosities than in the 
one described by Pennant, but this may probably arise from 
their not being quite so adult. 

The following species are very doubtful. The first ap- 
pears to depend on a badly observed young specimen, and 
the latter most probably arises from the error of the artist 
and the describer.

on the front edge.

Cuvier {R.A.n. 15), I think, correctly, regards Bartram's 
figure as only a T. ferox to which the artist has given addi- 
tional claws, and some aiijjearance of dorsal shields, pro- 
bably arising from the specimen having been partially dried, 
so as to show the bones through the skin. 

Head large, broad behind. Muzzle elongate, conical. 
Lips thick. Dorsal shield flexible on the edge. Ribs 8-t^, 
not united into a solid disk until late in life. Sternum 
narrow at each end ; callosities 2, small, only attached to 
the outer processes of the front lateral sternal bones. Epi- 
sternal lines forming a V, but not contiguous at their base.

Rondeletius {De Pise. Mar. 4.11) thought that it was 
from the bones of this animal that the ancients formed 
their lyres, and for this reason it was called the Luth by 
Lacepede ; but the remains of the Greek lyre in the British 
Museum are evidentlv formed from bones of Testudo grieca. 

A skull labelled T. coriacea, from the Pacific Ocean, 
presented by Mr. Collie to the Haslar Museum, is so like 
that of C. Midas, as not to be distinguished from it ; the 
hole of the ear appears rather rounder than in the other 
skull, but very slightly so.

The skull (Cuv. Oss. Foss. t. 11. f. 1-4) broad, short ; 
forehead flat, shelving, with the nose on the slope of the 
face ; the inner surface of the bones of the jaws smooth 
(the ridges being on the homy sheath). The pterygoids 
are broad, concave, with a deep diverging groove on each 
behind, edging the very narrow linear ridge-like triangular 
part of the body of the sphenoid, which has part of the 
basilary between it. Last vertebral bone narrow, elongate, 
thick-keeled, of nearly the same width the whole length. 

The outer edge of the pterygoid bones is produced into 
a lobe in the middle : this lobe appears to diminish in size 
as the skull reaches adult age. 

The frontal (Cur. Oss. Foss. t. 11 . f. 2/) does not ap- 
pear to increase in size so rapidly as the other bones, being 
larger in comparison in the young than in the adult skulls.

" The Caret or Hawkbill Turtle is called Kookeoloo or 
Kooseomboo by the Cingalese. It is caught on the southern 
coast of the island (Ceylon), and is very abundant at Point 
de Galle and Matura. It is rare on the northern part of the 

coast. Some specimens are sold for as much as £4 ; the 
price depends on the quality of the shell (shields). It is 
said that the natives remove some of the shields while the 
animal is alive, and return it to the sea; the shields are 
said to be reproduced, but for the truth of this we cannot 
vouch. The natives eat the flesh of this Turtle, but it is 
unpalatable to Europeans." — Kelaart, Reptiles of Ceylon,

"This species, the 'Pinyu' of the Malays of Pinang, is 

at all seasons plentifully taken in the fishing stakes in the 
Straits of Malacca, and is the ' Green Turtle ' of the Euro- 
pean inhabitants of our Malayan settlement and of the sea- 
ports of India. In size it equals Chelonia Midas, Schweig. 
(of the Atlantic), which it rivals in flavour. About De- 
cember and January is the season when the female deposits 
her eggs in the sandy beach of some sequestered island, 
and then the fishermen watch during the moonlight nights 
to ' turn turtles.' The eggs are of a spherical shape, 
about one inch in diameter, covered with a soft hemitrans- 
parent membrane of a pale yellowish colour. The expert 
eye of the fisherman baffles the pains with which the turtle 
conceals her eggs, and prodigious numbers are disinterred. 
They are very rich-flavoured, like marrow, and will keep 
for weeks although exposed to the air." — Cantor. 

" The breadth of the fronto-nasal shield in Chelonia vir- 
gata is only one-third of the length, whereas in Chelonia 
Midas it is one-half, and these proportions appear to be 
constant in all ages of the two species. The very young 
of both greatly resemble each other in colour and shape. 
Six liy-ing young were all of the following dimensions : — 
Head ^ ; neck j ; shell 2 ; tail \ of an inch ; and they pre- 
sented the following peculiarities : — 

" The shell cordiforin, the length exceeding the breadth 
by one-eighth ; the second vertebral shield much broader 
than the first, and altogether the largest of the series ; the 
second costal shield larger than the third ; the breadth of 
the fronto-nasal shield one-third of the length. Each fin 
with a single claw." — Cantor. 

"This Turtle (^Chelonia virc/ata) is found all round the 
island (Ceylon), and is very numerous in the Trincomalie 
Harbour for several months in the year ; a good-sized one 
can be bought for 6d., a very large one for \s. 6d. to 2s. The 
flesh of this Turtle is not far behind in flavour that of the 
well-known Green Turtle (Chelonia Mydas), so famous for 
making the T\irtle soup. The female lays from 100 to 200 
eggs of a globular shape, with a soft semitransparent cal- 
careous shell, which are much prized as articles of food by 
natives and Europeans. A native will consume as many as 
20 or 30 eggs at one meal, and we have seen Europeans eat 
a dozen for breakfast." — Kelaart, Reptiles of Ceylon, 181.

The skulls differ considerably in the convexity of the 
forehead, and they offer two distinct peculiarities, which 
may indicate two species or the two sexes. 

In one form, of which I have examined four skulls of 
different ages, the width at the condyles of the upper jaw 
is the same as the distance from the edge of the vertebral 
condyle to the front edge of the palatine opening. 

In the other variety, of which I have examined five, all 
adult, skulls, the width of the condyles of the jaw is 
considerably more (half an inch) than the above-named 
distance. In the Chelonia Caretta the width of this part 
is very much greater than the space above named. 

I may observe that in the youngest skulls of the first 
variety the condyles are narrowest, so that part of this dif- 
ference may depend on the age of the skulls, which appear 
to become broader and shorter as they become older.

" It possesses a strange mixture of the characters of this

Geoclemys Seba (p. 18). 

Dr. Kelaart believes that Geoclemys Seba (p. 18) is the 
young of Emys trijuga (p. 20), the difference in the form of 
the shell and the spotting on the head depending on the 
age of the specimens. I have never seen the young E. tri- 
juga, the adult G. Seba, nor any specimens in an inter- 
mediate state of growth. I may observe that the fore feet 
of Emys trijuga show its affinity to the genus Geoclemys, 
though the skull is that of an aquatic Emys.

coloured markings ; plastron yellow in the middle, with 
large blotches of black and dark brown at the sides and 


anteriorly and posteriorly ; under surface of tail and ex-

Length of carapace G^ inches." — HaUoweU. 

M. Leconte observes : " In the English Catalogue (of 
the British Museum) are described E. rivulata, E. scripta, 
E. HolbrooJtii, E. macrocephala and E. Bennettii. Not 
having these, and knowing that the descriptions must have 
been taken from dried and faded specimens, or from such 
as were bleached by long immersion in alcohol, I do not 
hesitate to pronounce them as having no real existence as 
distinct species, or at most as being slight variations from 
others well known and long ago determined." — Proc. Acad. 
Nat. Sci. Phihtd. vii. 190. 

The figures in this work will show the evil of making 
such general assertions without examining the specimens on 
which the species are founded, and also that not one of 
them was described from either faded or bleached specimens.

the hinder outer angle of the shield, and a small arched 
streak on the outer part of the front edge, com^ileting 
the outline of the spot on the preceding shield, so as

3. Pseudemys serrata (p. 34). 

Shell of live animal dark ; the costal shields divided in 
half by a broad transverse red band, rest subannulated. 
Under side bright red, as figured by Holbrook. Very active 
and vicious. Zool. Gardens. (Dec. 1855.) 

M. Leconte regards Emys serrata, Say, E. rubriventris, 
Lecoate, E. irrigata, Dumeril, and E. rugosa, Shaw, as 
synonyms of the same species, observing that it varies very 
much, but the essential character is the dentation of the 

M. Leconte considers, certainlj' erroneously, Emys ornata 
and E. annulifera as synonyma of E. hieroglyphica of 



1. Cistudo Carolina (p. 39). 

M. Leconte erroneously cousitlers the variety C. Blan- 
dingii of Holbrook as synonymous with Lutretnys Melea- 
gris, a European species. — Jouni. Acad. Philad. vii. 189. 

M. Leconte, not having seen C. Mexicana, refers it as a 
variety of C. Carolina with doubt. 

14. KINOSTERNON (p. 43). 

In the Proceedings of the Academy of Natural Sciences 
of Philadelphia for 1854, vol. iii. no. 5. p. 183, there is a 
paper by John Leconte, entitled " Descriptions of Four 
Species of Kinosternon" read on the 31st October 1854. 
The genus is divided into three groups, thus : — 

I. Consisting of those with bivalve sterna ; the valves 
joined to the abdominal piece by ligamentous hinges. 

1. K. longicaudatmn, Spix, Bras. 17. t. 12. 

2. K. scorpoides. Surinam. 

3. K. Mexiconum. Testa ovali, valde convexa, fusco-lu- 
tescente vel nigricante ; dorso fortiter tricarinato, margine 
undique decHvi, scutis vertebralibus secundo, tertio et quarto 
elongatis. Sterno utrinque rotundato, integerrimo ; cauda 
unguiculata. Mexico. 

4. K. integrum. Testa fusca, regulari, ovali, convexa, 
carinata, declivi, margine postice dispanso, laterali perpen-' 
diculari. Sterno magno, bivalvi, cistani omnino occludente, 
antice rotundato, postice paulo emarginato ; cauda brevis- 
sima, mutica. Mexico. 

5. K. lexicostomum, Dumcril, Mus. Acad. 

II. Anterior valve of sternum joined to the abdominal 
portion by a ligament and partly by a suture, the posterior 

by suture only ; wings tolerably long, with a deep divided 
groove on the anterior part. 

6. K. Pennsylvanicum. From Canada to Florida. 

7. K. Sonoriense. Testa modice convexa, postice latiore, 
antice et postice declivi, margine antice et postice dispanso, 
medio declivi, dorso indistincte tricarinato, carina intermedia 
vertebrali evidentiore ; alarum canali leviter exarata, prope 
rudimentali ; cauda unguiculata. Tacson in Sonora. The 
shell much less elevated than any other species. 

III. Sternum narrow, subcruciform ; valves joined to the 
abdominal portion of the chest by sutures, the lateral teeth 
of which are so large as to admit of but little motion, 
especially in the posterior one ; wings long and narrow, 
without any groove on the inner part. Tail unarmed. 

8. K. odorutum. From New York to Florida. 

9. K. guttatum. Testa ovali, dorso subtricarinato, fla- 
vida fusca maculata, margine undique postice valde declivi, 
minims expanso. Sterno flavescente, angusto, antice trun- 
cate, postice late emarginato, femoribus et cruribus seriebus 
pai5illarum latere interiore echinatis ; cauda mutica. Penn- 

As I have not seen the species here described as new, I 
can give no opinion on their distinctness. A'. Pennsylva- 
nicum, from the description of the young, is evidently the 
species I have described under that name, but the other 
descriptions do not appear to be intended for the new spe- 
cies I have described ; at least the characters on wliich I 
have founded the species are not observed. 

K. guttatum, which is described as subcarinate, is evi- 
dently not the Aromochelys cai-inatum of this work. 

M. Leconte considers K. Doubledayii, from the descrip- 
tion given, to he a distinct species.
