202 W. T. Blanford — Monograph of Clausilice. [No. 3, 



Sab. — Khasi hills, North-east of Bengal, and Sonth of the Assam val- 

 ley. 



The locality usually assigned to this shell, Bengal, conveys a false 

 impression, as neither this nor any other Olausilia is found in the plains of 

 India. Teria ghat, the locality mentioned in the Conclwlogia Indica, is at 

 the southern hase of the Khasi hills, and the shell is found at many places 

 along the range, from the base Lip to a height of, I believe, 4000 or 5000 feet. 

 Major Godwin- Austen sent me this species from Habiang on the Khasi 

 plateau. I do not know if G. loxostoma occurs also on the northern or As- 

 sam flank of the range ; I have never seen specimens from any place in that 

 direction, and as the climate is much drier, many of the shells common on 

 the southern watershed are wanting to the north. 



The form of this species varies considerably, some specimens being much 

 more fusiform than others. I have figured three varieties, of which figure 6 

 may be considered as the typical form.

7a. Var. tumida, anfractibus ultimis aperturaque majoribus. Long, 

 circa 33, diam. 6'5 mm., apert. 7 longa, 5 lata. 



Sab. — In "North Cachar," (Godwin -Austen). 



This fine species, the largest hitherto found in Assam or the Himalayas, 

 resembles O. loxostoma in its strongly crenulated sutures and in form, but 

 differs in its larger size and more numerous whorls. It was first found by 

 Mr. Masters in 1860, in the hills south of G-olaghat, together with Spiracu- 

 lum Haster si and other interesting shells. The more tumid variety has late- 

 ly been obtained in North Cachar by Major Godwin- Austen.
