In this species the spire is shorter than in C. scalarina, the 

 ribs are more numerous, they are slightly reflected, and at the 

 angle of the whorl produced into three points. The colour con- 

 sists of two dark brown bands, which are as distinct in the 

 aperture as on the whorls.

Of an obhquely oval form with laminated ribs in an obbque 

 direction, crossed by raised lines, which near the suture of the
