I have had specimens of this shell from Dr. Jerdon, Major 

 H. Alexander, Mr. Fairbanks and others. Mr. Shurtleff assigns 

 it to H. labiata. It has also been considered a variety of H. 

 vitrinoides. Besides its great thinness, the absence of any labia- 

 tion inside the peristome, and of the colours observable in the 

 aperture of H. labiata, Pfr., which I discovered, in 1838, in the 

 Western Himalaya, it is distinguished by its subangular peri- 

 phery and marginate suture from that and any other allied 

 form.
