B ' test ^ ovat ^> ventricosa, albescente vel castanea, albo et fulvo fasciata, 

 transversim striata ; spira brevi ; sutura canaliculata ; apertura alba, subro- 

 tundata ; labro dextro tenui, crenulato, intus striato. 



Shell ovate, ventricose, of a whitish or chestnut color, 

 marked sometimes with deeper spots ; suture deep and canali- 

 culated, the exterior edge of which is slightly rounded and 

 surrounded by a white band, alternated with fawn-colored 

 blotches. Spire scaffolded, formed of six or seven nearly flat 

 whirls ; the lowest, on the contrary, is very convex, and larger 

 than all the others united. Upon the surface of this shell, are 

 seen equal, raised striae. Aperture white, sub-rotund, narrowed 

 at the upper part, dilated inferiorly ; right lip thin, crenulated 

 upon the edge, and marked interiorly with very prominent 

 transverse striae ; columella arcuated, covered by the left lip, 

 which is obliterated, flattened and corrugated above ; it forms, 

 from the middle to the base, a thick and projecting callus, 

 which is terminated by a very apparent fold, and by two 

 guttules. 



Length 13 lines. Width 10 lines. 



Inhabits the Indian Ocean, the coasts of Senegal, and of 

 America. 



This shell is very remarkable for its globular form, and for 

 the upper whirls, which sink within each other, with a pretty 

 distinct suture. It has some resemblance to the CASSIS canali* 

 culata of Bruguiere.
