254 Zoological Society :-- 
other day, in connexion with some other Terrapens more lately re- 
ceived, it appears to be distinct from any other that we have, and 
from any that I can find described. Unfortunately it was not ac- 
companied by any account whence it came, so that I cannot give 
its habitat. 
GEOCLEMYS CALLOCEPHALUS. 
Shell oblong, convex, bluntly keeled ; dark blackish brown ; shields 
thin, slightly ringed, the margin nearly entire ; vertebral shields about 
as long as broad, the second and third rather longer; nuchal shield 
short ; the marginal shields broad, the ninth rather higher than the 
rest ; underside of these yellow, not spotted or ringed; the sternum 
convex, rather bent up in front, broadly truncated before, and behind 
pale yellow, more or less blackish on each side of the central line. 
The upper part and side of the neck pale; the upper part of the legs 
closely speckled with minute black dots; the front of the fore legs 
pale, with some black spots on the edge of the large flat scales which 
cover this part; the front toes short, coalesced nearly to the claws, 
with a few rather narrow angular shields on the upper surface; the 
palms covered with moderate scales, and with a cross row of five 
large, nearly uniform-sized, squarish shields on the hinder part of the 
wrist ; the hind legs covered with small scales ; the hind foot broad, 
the toes short, and coalesced like the front one, but with rather larger 
shields above the soles, with moderate-sized scales, and with some large 
triangular shields at the hinder part of the heel, in two or three 
series ; the chin and throat white, spotless ; the head rather flattened ; 
the eyes lateral; upper jaw slightly notched in front; the crown of 
the head (in spirits) pale, with three black-edged white broad streaks 
concentric one within the other, and diverging parallelly towards the 
occiput, where they are lost among the black specks; cheek with 
five or six narrow black horizontal lines, the lower bending up to the 
tip of the ears; there is an obscure black streak from the nose to 
the middle of the orbit, and a narrow streak near the upper edge of 
the upper jaw, and some black oblong spots on the lower side of the 
ear and temple, which may be more distinct in the living specimen. 
Hab. Unknown; perhaps China. 
This species in several respects agrees in form and appearance with 
Emys chinensis, of which, as is shown by the specimen brought by 
Mr. Swinhoe to this country, the Tortoise described by me as Emys 
Bennetti is only the adult. It is at once known from &. chinensis 
by the minutely speckled body and the bands on the head, and by
