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 striz; these impressed strive 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 sparsely 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.
