Fic. 2.—Plastron of Tyionyx leithii (young), x %. 
4. Trionyx hurum, Gray (pl. v, fig. 3). 
Boulenger, Fauna, p. 13, fig. 5 (young): Siebenrock, p. 597. 
DISTRIBUTION.—The lower reaches of the Ganges ; the Brahma- 
putra as far north and east at the point at which it debouches 
on the plains. The species is said to occur also in Indo-China,’ 
and in the Malay Peninsula,? but the latter locality rests on 
insufficient evidence. Although 7. gangeticus makes its way as far 
north as the base of the Nepal foot-hills and as far west as 
Karachi, I have been unable to obtain any evidence that T. hurum 
is found much above Rajmahal. Moreover the only specimen 
(No. 10627) I have seen that was actually taken in Bengal outside
