Shell fusiform, strong, small, with nine flat, ribbed whorls, white 

 with brown blotches and lines. Suture deep and distinct, both 

 the upper and lower edges of the whorls being chamfered ; the 

 ribs on the body-whorl near the aperture less distinct than on 

 other parts of the shell; anterior portion of this whorl with 

 numerous revolving striae; these impressed striae give place to 

 colored lines as they ascend, and these are continued more or less 

 distinct to the apex, being visible only as they cross the ribs and 

 not in the intermediate spaces except here and there, where, being 

 more deeply colored and descending between the ribs, they pro- 

 duce the blotches which mark the shell. Aperture small, rather 

 wide in proportion, pillar lip much hollowed above, suddenly 

 becoming straight to form the canal ; outer lip considerably en- 

 larged, denticulated sparsel}' within; length a little over one-fourth 

 of an inch. 



A pretty little shell, allied to the group which embraces C. pul- 

 chella, Sowb. and C.jaspidea, Sowb. of West Indies; this species 

 being more elongated. 



A single specimen obtained from the stomach of a black fish.
