Inhabits Bengal, Nipal, and the North-Western Provinces, 

 Pegu and Tenasserim, 



In the Proceedings, As. Soc, Bengal, for March 1874, p. 83, 

 I inadvertently state that this species does not occur in Pegu 

 which is an error, though it does not affect my argument, as I 

 had no skull of it in my collection, and the only specimens I ever 

 obtained were a young one at Tonghu (shell only), and the aged 

 specimen noticed by Gunther in his Mon. Ind. Rep., p. 39, from 

 Moulmein.
