nean, the coasts of Provence, the Isles of Hieres, and those of 

 Sicily. 



This little shell is closely allied to the BUCCINUM coccimlla ; 

 nevertheless, it differs from it by the shortening of the whirls, 

 and by the more separated and more elevated folds, at their 

 upper part.

Shell ovate, ventricose, spire pointed, composed of six or 

 seven convex whirls ; it is ornamented upon its whole surface 

 with granular, longitudinal folds, and transverse striae. Suture 

 very distinct, formed by a small canal, and bordered with 

 closer tubercles, principally upon the lowest whirl, which is 

 very much inflated, and composes almost half of the shell. 

 Aperture rounded ; right lip arcuated, thin, folded upon the 

 edge, ornamented internally with raised striae, which are con- 

 tinued within the shell. Left, lip expands upon the colu- 

 mella, which is truncated towards the top, and extends like a 

 raised lip towards the base ; it is covered lengthwise by two 

 or three slightly marked, oblique folds. The interior of this 

 shell is of a diaphanous white, like the surface, which, more- 

 over, is covered with reddish clouds. 



Length 1 inch. Width 9 lines. 

 Inhabits the Indian Sea. 



The series of pearl-like tubercles which cover this shell, and 

 its coloring, of a brilliant white, mingled sometimes with rose 

 spots, particularly in young specimens, give it a most pleasing 

 appearance.
