where he says it is not rare locally. He continues, " It has one 

 whorl less than the type (which is described as having 7), but is 

 slightly larger, a difference probably due to the lesser elevation at 

 which my specimens lived. Shell with six whorls, outer edge of 

 aperture not quite so convex, or full, as in Nevill's plate. In 

 most other respects corresponding with the description of the 

 type. The surface under a lens displays a microscopically de- 

 cussated sculpture, not mentioned in the type. Two varieties 

 occur : var. major, long. 15, lat. 6*2 mill. ; var. intermedia, 

 long. 12, lat. 4*4. This last I do not term. ' minor ' as it is 

 actually larger that the type from Mari."

The species is characterized by the large body-whorl and the 

 strong decussated sculpture. It varies in size like most of the 

 members of the group. Dr. Kobelt records specimens from 

 Tandiani, in the Mollendorif collection, 14-5x7*5 mm., while the 

 Theobald collection contains shells from the same locality, measur- 

 ing from 13'75 x 5 tollx4'5 mm. The same collection com- 

 prises a series from the Jhilum Valley, above Kohala, considerably 

 larger than typical mainwaringiana. Two of these are here 

 figured ; they have the following dimensions : 16*5 X 8'5 and 

 15x7 mm.; while two others appear sufficiently distinct to base 

 two new varieties upon them.

Twice the length of the type and nearly three times its 

 diameter.
