 Hah. Mauritius. 



This species belongs to the Clavus group. It has been placed 

 in various collections as P. albicostata, Sowerby, w'ith which I find,

 Hah. Hong Kong. 



A very simple shell, wdthout sculpture, and with but few smooth 

 longitudinal ribs. It is hardly possible to say in which section 

 this species should be placed, whether it is a Drillia or a modifi-
