MOLIAJSCA OF INDIA. 269 



with faint, subdistant, longitudinal (spiral), impressed lines above 

 and often below, the spaces between the lines papillate, pale 

 yellowish to brownish horny ; spire low, suture well impressed ; 

 whorls 6, rather rapidly increasing, the last broader, rounded ab 

 the periphery and convex beneath ; aperture slightly oblique, sub- 

 ovately lunate, broader than high ; peristome thin, basal margin 

 almost straight when viewed from below, columellar vertical 

 above, then obliquely curved, rather broadly reflected at the 

 perforation. 



" Major diam. 20, min. 17|, height 10 mm. 



" Hah. Sikhim. Common in the Upper Teesta Valley about 

 Singtam (4000'-5000'). 



" This somewhat resembles M. seqnax, but is distinguished by 

 larger size and diifereiit sculpture. It is also very much like im- 

 mature shells of M. luhrica, but may be known by the presence of 

 longitudinal sculpture, more numerous whorls, colour, &c." 



I give drawings of this species so that they may be compared 

 with M. sequax, figured on Plate CVI. fig. 1.

Locality. Near Darjiling {Colonel G. B. Maimoaring). 



Shell well perforated, depressedly conoid, slightly shiny, thin ; 

 sculpture well marked longitudinal striation, in places broken up 

 into papillate dots, extending to the lower side ; colour olivaceous 

 umber-brown or ochraceous, on some a whitish narrow streak 

 extends from umbilicus close to peristome ; spire fiatly conic, apex 

 blunt, sides flat ; suture impressed ; whorls 5|, regularly increasing 

 to the fourth, the last more expanded ; aperture roundly lunate, 

 oblique; peristome thin; columellar margin subvertical, verv 

 slightly reflected above. 



8ize : maj. diam. 12"4, min. 11"3; alt. axis 5*5 mm. 



Eight adult and seven very young specimens were sent me by 

 Mr. G. Nevill many years ago, from what part of the Darjiling 

 hills was not stated. Colonel Mainwaring had native collectors 

 out, and perhaps took no special care to record the exact habitat. 



The sculpture of this species is sufficient to distinguish it from 

 shells of very similar form. The original description and figure 

 were made from an immature shell.
