below, brownish tawny; sculpture as in M. hardwickii, the longi- 

 tudinal striae very close and minute, only visible under a strong 

 lens ; spire low, conoidal, suture impressed ; whorls 6, convex 

 above, the last rather broader, rounded at the periphery, tumid 

 beneath ; aperture oblique, roundly lunate, margins converging ; 

 peristome thin, basal margin subarcuate, coluinellar margin much 

 curved, vertical above and rather broadly triangularly expanded 

 and carried forward, not reflected. 



Major diam. i!2, min. 20, height 14. Larger specimens mea- 

 sured 24i X 22i X 14| and 26 x 23^ x 14^.

This resembles M. hardivickii in form and sculpture, but is much 

 larger and has a more open umbilicus. It is distinguished from 

 M. indiea, J\J. j^t^trosa, and AI. peiylana by more globose form and 

 by sculpture. It differs from Jf. pe'c^ina in smaller size, different 

 sculpture, rounder periphery, and more open perforation. The 

 expanded portion of the columellar margin, viewed from beneath, 

 is carried forward almost at right angles to the direction of the 

 basal margin. 



The locality originally assigned to this species, the Anaimalai 

 Hills, appears to have been given in error, as in the case of 

 M. lixa.
