B. testa ovato-conica, rufo-fuscescente aut olivacea, laevi, basi transversib 

 sulcata, prima estate longitudinaliter plicat& et transverse striatii ; apertura 

 ovata, albescente ; labro dextro crasso, exttis marginato, intus striato. 



Shell ovate, conical, of a reddish or olive color, composed 

 of eight or nine whirls, the lowest of which composes nearly 

 half of the shell ; it is smooth, slightly arcuated, and often- 

 times ornamented upon each whirl with a whitish band. When 

 young, it is marked with convex, longitudinal folds, which are 

 intersected at the base of the lowest whirl only, by five or six 

 pretty deep transverse striae ; upon the upper whirls the folds 

 are much more close, and also more prominent, than upon the 

 lowest, where they oftentimes disappear altogether. The 

 edge of the aperture is whitish, ovate, notched at both ends, 

 the cavity of an ash color ; the notch above is small, placed 

 upon the upper edge of the right lip, where it is contracted 

 to the form of a small canal ; the emargination of the base is 

 arched ; right lip thick, margined exteriorly, crenulated indis- 

 tinctly upon the lower edge, and marked within with very 

 distinct, transverse striae. The left lip is continued in front, in 

 a thin leaf which extends a little over the columella : it is 

 smooth interiorly, and edged throughout its whole length with 

 a row of small drops. 



Length 1 inch 9 lines. Width 10 lines. 



Inhabits the seas of the Antilles at Guadaloupe, the Indian 

 Seas at Ceylon, and the coasts of Chili. , 



When the specimens of this species are young, the longitudi- 

 nal ribs are very prominent upon the whole shell, and the trans- 

 verse striae are very numerous and very approximate ; they are 

 effaced by age. The coloring is sometimes whitish near the
