generic rank. Without in any way presuming to criticise Prof 

 Piisbrv's views, the concliological characters seem to be correlated 

 with certain anatomical details. In Pledotropis a flagellum occurs 

 which is wanting in Eidota s.s. In the former the epiphallus is 

 long and the duct of the spermatheca is bound to the oviduct, in 

 the latter it is inserted high on the vagina and the epiphallus is 

 short. In Plectotropis the jaw possesses 10-19 ribs, in Eulota it 

 is provided with only 4-11 ribs.

Differs from the type by its more raised spire, stouter texture, 

 and less 01)611 umbilicus. Xevill considers the shell represented 

 in Conch. Ind. pi. 15, fig. 8, not to be a typical specimen from 

 the North-West Himalayas, but rather a specimen from Darjeehng. 

 The former, he states, is a smaller, more rounded, and less solid 

 shell scarcely keeled at the periphery, with a higher spire and
