But a single specimen has been sent by Col. Beddome. I think I have 

 seen the same, or a very similar form, from either the Pulneys or some 

 other range of Southern India ; but I cannot find specimens in my collec- 

 tion.

Hab. Cum prsecedente. 



Sliell imperforate, conoidly depressed, above ornamented with oblique, 

 close, and arcuate fine hair-like costulation, smooth and marked with radia- 

 ting strise below; pale horny, paler beneath. Spire depressedly conical, the 

 sides nearly straight, apex rather sharp, suture impressed. Whorls 8, convex, 

 narrow, slowly increasing in size, the last angulate above at the perij^hery, 

 scarcely descending towards tlie mouth, convex below. Aperture oblique, 

 lunate, broader than high. Peristome not shai'p, slightly wavy, with a very 

 slight white thickening inside, the basal margin curved forward, the colu- 

 mellar scarcely reflected. Major diameter 0-67, minor 0-62, axis 0-38 inch. 



The above is the typical form ; but there is a smaller variety, depress- 

 edly turbinate in shape, with the spire conical, measuring 55 inch in its 

 major diameter and 0'36 in height. This form passes by insensible grada- 

 tions into the type. 



The shell represented in the ' Conchologia Indica' is intermediate 

 between the two varieties here described and figured ; the apex in the 

 ' Conchologia' figure is more prominent and blunt than in the s^^ecimens 

 now before me. These were procured from the Naga hills, south of Gola 

 Ghat, Assam, by Mr. Masters in 1859 ; other specimens were subsequently
