 apex subacute, suture impressed ; whorls 6-7, slightly convex, 

 slowly increasing, the last rounded at the periphery, convex 

 beneath ; aperture very slightly oblique, almost vertical, lunate ;

This shell resembles the Tenasserim M. petasas (p. 115) closely 

 in shape and colour, and I long regarded the two as identical : but 

 J/, notha is distinguished by wanting the labiation of the 

 Tenasserim species, by being less polished, and by its sculpture, 

 w hich can only be seen under a microscope.
