Localhity.— Harmutti, base of Dafla Hills, No. 445 B.M. (Godwin-

This takes the place in the Dafla Hills of G. baculina of Sikhim. 
It is very similar in all respects, but the apex is more obtuse and 
the sculpture is very different: there are four specimens, 
Two young specimens, unnamed, were found in Henry Blanford’s 
collection, given to him by me.

The figure in the ‘ Conchologia Indica,’ pl. xxxvii. fig. 2, is a 
very good one, and undoubtedly of Benson’s species. 
The Blanford collection (No. 844, 06.1.1, B.M.) contained 
3 specimens from the Dafla Hills, sent to him by me, but probably 
maj. diam. 6°8; length 18-8 mm.
