Hob. Lake Chilka (type) ; also Port Canning and Madras. 



Of the operculum the author further states : "it is oval, semi- 

 transparent, spiral, of few whorls, with the apex also central, on 

 the inner side three ridges, one semicircular and two short ones 

 with a slight S-curvature, for the attachment of the animal. 



" The species is somewhat variable, especially as regards size 

 and the greater or less distinctness of the angulation of the last 

 whorl. Specimens from Port Canning agree better with the above- 

 described typical form than do those from Madras." 



The type is in the Indian Museum, Calcutta.
