252 LAND AND FRESHWATER 



low, convexly conoidal, apex obtuse, suture scarcely impressed, 

 shallow ; whorls 6, flatly convex above, the last broader, rouaded 

 at the periphery, convex beneath ; aperture subvertical, broadly and 

 ovately lunate, margins converging ; peristome thin, the basal 

 margin slightly arcuate, columellar margin vertical for a short 

 distance above, and reflected, then curved and oblique, slightly 

 expanded. 



" Size : niaj. diam. 12|, rnin. 11|, heiglit 60 mm." 



The type shell is figured from Brahmakund on the Lohit River.

LocaliUj. Nortb-East Munipur ( W. Ogle). 



Mhell narrowly perforate, thin, polished, very flatly conoid ; 

 sculpture none, quite smooth ; colour dull burnt-sienna ; spire 

 flatlv L-onoid, low, sides flat ; suture impressed ; whorls 5|, regu- 

 larly increasing ; aperture lunate, width greater than length, 

 subvertical ; peristome thin ; columellar margin rather solid, not 

 reflected, oblique. 



Size: maj. diam. 12"0, min. 10-5 ; alt, axis 4-75 mm. 



This is a close ally of M. tenninus, but is far flatter, both above 

 and below. I have a good series of ten all alike.

Locality. Hengdan Peak, Burrail Range, Assam (Godwin-Austen). 



The type shell was found on this peak and was described in 

 Yol. II. p. 136, but it was never figured, and this I now do. 

 Besides the localities pi'eviously mentioned, I have specimens from 

 Phunggam and Gazi[)liinia in the Lahupa JSaga Hills, rather more 

 openly umbilicated. The dwarf variety mentioned at p. 136, of 

 which I now figure a specimen (Plate CXXXf. figs. 10, 10 a), has a 

 very thickened lower margin and is exceptional. It was from 

 Phunggam in the Lahupa Xaga Hills, JS^.E. Mumpur.

Shell very globosely depressed, perforate ; sculpture, apparently 

 quite smooth ; colour, specimen bleached ; spire low, sides flat, 

 apex blunt ; suture impressed ; whorls 5, regularly increasing, the 

 last somewhat tumid, well-rounded on the periphery, descending 

 at the aperture ; aperture seiniovate, oblique ; peristome thin, in 

 the figure a fresh growth of shell is indicated ; columellar margin 

 very oblique and slightly reflected near the umbilicus.
