Shell openly perforate, conoidly depressed, pale horny above, 

 regularly and arcuately costulate, smooth, polished, with obsolete 

 radiating striation beneath ; spire low but varying somewhat in 

 elevation, apex slightly prominent, suture impressed; wliorls 7, 

 closely wound, convex above, the last subangulate at the periphery, 

 somewhat tumid beneath ; aperture oblique, lunate ; peristome

Hah. Pankabari, at base of Sikhim Himalayas {W. T.B.); 

 Someysar Hills, north of Gorakpur (Theobald) ; probably foot of 

 Himalayas in Nepal and Sikhim. 



Yery similar to the typical depressed form of K. vidua, but 

 distinguished by being perforate and by its much stronger and 

 more regular sculpture.

 and less excavated in the umbilical region, with a rather higher 

 spire and finer closer costulate striation above ; there are 7 whorls 

 in adults ; the peristome is thin, without any trace of internal 

 labiation.

Shell openly perforate, conoidly depressed, thin, horny, with 

 fine, oblique, arcuate, subdistant, filiform costulation above, the 

 riblets extending to below the periphery, smooth, polished, and 

 radiately striated beneath ; spire low, conoidal, suture impressed ; 

 whorls 6, convex, rather closely wound, the last broader, sub- 

 angulate at the periphery, convex below, concave around the 

 umbilicus ; aperture slightly oblique, lunate ; peristome thin, basal 

 margin arcuate, columellar nearly vertical and produced forwards 

 at the umbilicus.

Hah. Habiang Garo Hills* {Godwin- Austen) ; Upper Burma 

 (Fea). 



* [This indicates the southern side of the hills intervening between the 

 western boundary of the Khasi Hills and the independent Garo tribes. When 

 I was there in 1866, the people were hardly under our rule, but were safe 

 to go among ; not so the Garos on their west. I cannot say whether Habiang 

 Garo is the Khasi name for these people or whether it is a Garo term.]
