" Tbis shell is, in some respects, intermediate between 

 B. paclujcheUus, Bens., and D. diplocheUnx^ Bens. It has the 

 general form of the first, but resembles tlie last in its smooth 

 lower whorls. The peristome is largely developed and ]3ecnliar, 

 the inner portion being flatly expanded and almost divided into 

 two portions by a groove, so that the whole lip is almost triple."
