 angulato ; apertura quadrata, peristomate tenui, acuta, margine 

 columellari, neciion basali, p)arura expansiixsculo. 



" Diam. major 4^, minor 4, axis 4 mill. 



" Habitat ad Teria Ghat, montium Khasiaj. 



" A pretty little species, distinct in character from any Indian shell 

 yet published, and remarkable for the frequent strong and regular 

 ribs, and for its thread-like carination." 



Eahula POLYrLETjEis, W. T. Blf. (Plate CXVII. fig, 2.) 



Helix polypUuris, W. Blf. J. A. S. B. 1865, p. 76. 

 Xerophila (section Turricida'^) polypleuris, Blf., Clessin, Nomen. 

 Helic. 1881, p. 133. 



Original description: — "Shell openly umbilicated, trochiform, 

 rather solid, white (probably horny in living specimens), obliquely 

 and closely costulated. Spire conoid, apex rather obtuse ; suture 

 impressed. Whorls 6, convex, slowly increasing ; the last not 

 descending, surrounded by a raised thread-like keel, convex beneath 

 and sometimes somewhat sinuously radiately costulated around the 

 deep and pervious umbilicus. Aperture oblique, roundly lunate, 

 almost circular ; peristome thin; margins distant, columellar slightly 

 expanded. 



" Major diam. 4, minor 3|, axis 3 mm, 



" Habitat. Arakan hills ; rare. 



"A prettily marked little species near i/^.6oscai6c?a,Bs., from which 

 it is distinguished by its finer and closer sculpture, more open 

 umbilicus, and less conical spire. It is very probably a Nanina, 

 but the animal was not met with."
