The lower whorls of this species present indications of 

 three faint ridges in place of the keel, and the columella 

 has a purplish-ruddy hue. 



Species 329. (Mus. Cuming.)

 ovate, but little effused. 



Lea, MS. in Mus. Cuming. 



Hab. ? 



Of this specimen, received with the above name from 

 Mr. Lea, Mr. Cuming has no habitat ; it is probably a 

 United States shell, but it partakes a little of the Guiana 

 type of the genus.

 anfractibus septem ad novem, Irevibus, ad suturas sub-
