"It appears to be very close to Bui. putus Bs. (Annals 

 and Mag. Nat. Hist., April, 1857), from Tavoy. Specimens 

 differ very much in size from different collections. The shell 

 is very finely developed in the high parts of the North Cachar 

 Hills at 6,000-7,000 ft. (fig. 53) . At Cherra-Poonjee it seems 

 a more tumid form (fig. 55), and it is very frequently 

 dwarfed to the length of only 0.36 inches, especially in its 

 lower habitats ; but these variations are not of sufficient spe- 

 cific importance."
