Three anterior vertebrals squarish, the fourth much longer than broad, all keeled in young individuals, but the keel disappears with age. The hind margins of the ])ost-gulars meet at an obtuse angle.

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 Tonghii (shell only), and the aged specimen noticed by Gunther in his Mon.
