C. testa ventricosa, costis longitudiualibus angulatis, et costis 

 spiralibus super costas longitudinales acute angulatis, cancellata : 

 anfractibus angulatis, ad angulum coronatis; apertura postice et 

 antice caualifera, interne costata, margine dentato, columella crassa,

 ad angulum et in medium anfractuum fusco fasciato. 



Differing from C. cancellata in the angularity of the whorls and

 coronated and the edge of the aperture dentated. 



Collected by Mr. Cuming at St. Elena, in West Columbia ; sandy
