Sab. — Western Himalayas from the western frontier of Nipal to the 

 Satlej valley, at elevations from 5000 to 9000 feet. 



The figure in the Conchologia Indica is that of a specimen which, 

 although adult, has retained its apes. This is a very rare occurrence. The 

 figure now given represents the shell as it is usually found. 



Three palatal plaits, the upper elongate, are always present, and beneath 

 them there is occasionally to he found a rudimentary lunella. The charac- 

 ters both of the shell and of the internal plication differ widely from 

 those of typical Phaedusa, in which sub-genus I do not think that the 

 present species can be included. It stands by itself, and I am inclined to 

 look upon it as the type of a peculiar section. 



Section II. — fMedora H and A. Adams. Shell fusiform, homy, costulate 

 or smooth, apex not deciduous. Lunule developed, with few, usually two, 

 palatal plicse above it, the upper elongate.

Hob. — Temperate regions of Sikkim and Biitan, in the Eastern Hima- 

 layas, from about 5000 to 9000 feet. It doubtless also exists in Nipal, 

 It is generally met with at the roots of oaks and other large trees. 



In this species, as was noticed by Mr. Benson, the lunule is sometimes 

 broken up into short oblicme plaits above, and consequently the number of 

 palatal plica? varies. Sometimes there is only the long lamellar plait above 

 the lunule, in other specimens there are, besides the long one, two short plicse.
