JIab. Goree, West Ahica. (Denans). 



A shell of striking characters, remarkable chiefly for the 

 smooth concave declivity of the whorls. It bears some 

 rcsemb'ance to C. gravida, Hinds, but the angular keel 

 is not tubercled as in that species, the whorls above the 

 keel are more decidedly concave, and t!ie sinus is broader. 

 I have only seen a single specimen of this species.

Testa minuta, solidiuscula, utrinque acuminata, aurantia, lineis 

 fuscis, angustis (circ. 5) aequidistantibus ornata, ubique spiraliter 

 sulcata; spira elatiuscula, gradata ; anfractus angulati, ad angu- 

 lum linea t'usca oriiati ; spira obtusa. i)apillaris.
