Obs. Six specimens in the collection all accord 

 perfectly in the characters above given : the longi- 

 tudinal undulations, or folds, are very prominent, 

 and the transverse ribs, or groo\es, run over them. 

 It is remarkable that the fifth tooth from the base of 

 the outer lip is the largest, and that it corresponds 

 to a groove that is more deeply marked on the out- 

 side than the others. This shell resembles B. Tran- 

 quebaricum in general form ; in the latter remark- 

 able character, however, it will be found to diflfer 

 materially. There are some fuscous spots sprinkled 

 over the ribs.

 mcrosissimis fuscis ; spirte apice papilloso ; anfrac- 

 tibus rotundatis, supcrne depressis ; columellaE 

 basi acuta: long. 1^^ lat. 1 unc. 



Obs. One specimen of this pretty shell adorns 

 this collection, it is the second that has come under 

 our observation, another, which was in the African 

 Museum, being in Mr. Broderip's possession. Tlie 

 species has not the spiral channel within, that dis- 

 tinguishes others of the genus.

rata, from which, however, it may be distinguished
