Shell ovate. The nuclear whorls are dark chocolate-brown; the 

 first postnuclear turn is buff; the rest are chocolate-brown, becoming 

 darkest on the last part of the last turn. The postnuclear turns are 

 covered with a moderately thick periostracum, which is blotched or 

 streaked with buff or orange-buff, the base being darker than the 

 posterior portion of the last whorl. The base is rather short, some- 

 what inflated, and strongly rounded. Aperture broadly oval. The 

 peristome is expanded and reflected, particularly at the insertion of 

 the columella, where it is reflected over the umbilicus, which it more 

 than half covers. The parietal wall is covered by a rather thick 

 callus. 



This race differs from Cochlostyla (Chrysallis) aspersa mindoroensis 

 in being more ovate, more inflated and chubby. It differs from 

 Cochlostyla (Chrysallis) aspersa lunai in being in every way smaller. 



The specimen described and figured (U.S.N.M. no. 313740a) is 

 one collected by the Menage Expedition, as stated before, probably 

 on the western shore of Lake Naujan. It seems to satisfy most 

 closely the figure given of this species by Grateloup (see pi. 112,
