Allied to H. labiata, Pfeiffer, a Western Himalayan shell, but 

 differing in its more depressed form, peculiar sculpture, like that 

 of the upper part of H. ligulata, by its more widely lunate aper- 

 ture, and by the absence of any true labiation. The colour may 

 be more pronounced in fresher specimens.
