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. 



Geoclemvs 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 

 JEmi/s 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 E. chinensis 

 by the minutely speckled body and the bands on the head, and by
