new MoUusca from South Africa. 105 



Two specimens, neither in very good condition. 



The shape is peculiar, ovate-pyramidal, the last whorl 

 rapidly increasing, somewhat effuse, the other whorls small 

 in proportion ; the surface, excepting that of the basal half of 

 the last whorl, which is smoothish though longitudinally 

 wrinkled, granato-decussate. 



This appears to be a very distinct new form.

Hah. Yan Staaden's River (/. Crawford, Esq.). 



A smoothish glassy species, to wliich we cannot assign a 

 place as the young of any South- African form with which 

 we are acquainted, several of the specimens before us being 

 apparently full-grown.

A very pretty transparent, horny, pyramidal species, six- 

 Avhorled, attenuate towards the apex, the last whorl shoul- 

 dered, somewhat broadened ; whorls ventricose and impressed
