" A single worn specimen of this species is in the Collection. 

 In form and many characters it so nearly tallies with a little un- 

 described shell which I collected at Mussoorie and Landour, that 

 I feel much disposed to unite them ; but the greater comparative 

 solidity of the Darjiling specimen, the caducous epidermis, and the 

 circumstance of the margins being united by a callus, of which there 

 is no trace in any of my Western specimens, make it undesirable to 

 confound them until a series of the Darjiling species can be had for 

 comparison. The species was probably named by Mr. W. T. Blanford
