 PI. XXIII, fig. 90 et pi. XIV, fig. 49 var. 



B. testa ovato-conica, longitudinaliter plicata, transversim tenuissime 

 striatd, varic colorata, fasciis rufo-fuscis pictft ; anfractibus superne angula- 

 tis, supra complanatis, ad angulum crenulatis ; apertura ovata, albescente, 

 superne angustatd ; labro dextro superne emarginato, intus striato. 



Shell ovate, conical, whitish, ashy or reddish, oftentimes 

 with two brown bands which are sometimes interrupted ; spire 

 formed of seven or eight distinct whirls, flattened above, fur- 

 nished with longitudinal, almost perpendicular folds, which are 

 themselves intersected by striae visible only in the interstices 

 of the folds, except towards the base, and upon the whirls at 

 the top of the spire. The upper edge of the whirls is flatten- 

 ed, and bordered by rounded tubercles, which are separated 

 from the longitudinal folds by a deep stria running below 

 them. Aperture ovate, whitish, contracted at the top by a 

 transverse fold of the left lip. The right lip is emarginated at 

 its upper edge, marked interiorly with transverse striae in great 

 numbers. The left lip is obliterated and flattened at its sum- 

 mit ; it gives rise from the middle to the base to a pretty thick, 

 projecting callosity, in the form of a keel. 



Length 14 lines. Width 7 lines. 

 Inhabits the Indian Ocean. 



This species presents a great number of varieties ; in young 

 specimens the color is deeper ; the transverse brown bands are 

 more marked, and appear upon all the whirls; the shell has 

 also, proportionally, a more globular form. Other specimens 

 are of an uniform color, have the whirls strongly canaliculated, 

 and the longitudinal folds more approximate. We give a figure 

 of one of these last pi. 14, fig. 49.
