Shell subobtectly perforate, conoidly depressed (subglobose), very 

 thin, smooth, with a rather oily lustre above, more vitreous 

 beneath, pale yellowish amber to yellowish tawny in colour ; spire 

 low conoidal, apex rather acute, suture impressed ; whorls ()-'5|, 

 convex above, the last considerably broader, well rounded exter- 

 nally and beneath ; aperture slightly oblique, roundly lunate, 

 broider than high ; peristome veiy thin, in one plane, columellar 

 margin much curved, becoming vertical near the perforation and 

 triangularly expanded, but very little reflected. 



Major diam. 16, min. 13, height 9 mm. 



Hah. Eajmahal Hills; Orissa ; Cuttack (Theohald, W. T. B.) - 

 Oanjam. 



This species may be distinguished from its allies by its broader 

 last whorl and larger and broader mouth. 



[Animal from spirit-specimen (Eajmahal) pale in colour, with 

 slight coloration near the extremity of the foot, which has a 

 hooked overhanging termination. The right shell-lobe is mode- 

 rately long, tongue-shaped, and attenuate, the left is very small : 

 the left dorsal in two parts, overlapping. The generative organs 

 were not in the active stage and were very small. A coiled 

 cajcum is present in the penis, and the amatorial organ was 

 observed. Teeth of radula of usual form, laterals evenly bicuspid. 

 Eormula : 48 . 2 . 10 . 1 . 10 . 2 . 48, or 60 . 1 . 60. 



Jaw arched, with a central projection.]

Shell subobtectly perforate, conoidly depressed (depressedly 

 subglobose), thin, polished, smooth, ochraceous horny, sometimes 

 olivaceous ; spire conoid, slightly raised, suture deep ; whorls 5-6, 

 convex, the last much broader, rounded at the periphery, moderately 

 swollen beneath ; aperture oblique, elliptically lunate, decidedlv 

 broader than high ; peristome thin, straight, columellar margin 

 oblique, triangularly reflected above. 



" Major diam. 14, min. 13, height Sk mm." (Bs.). An immature 

 shell measures 11^ x 10 x 6| mm. 



Hah. Eajmahal Hills (5rtcou) ; Parasnath ? 



The typical form appears to pass into one with a rounder mouth 

 and vertical columellar margin, Benson's 31. vesicula from Bengal. 

 The shells from Assam and the Assam Hills are much stouter 

 than those from Western Bengal and may be a different species.
