Distinguished from all the preceding by its rose-pink lip and col- 

 umella. The beautiful granulation of the whole body- whorl, nar- 

 rowly pear-shaped aperture, and long, spaced folds of earlier whorls 

 (as in the foregoing group of species), will sufficiently separate B. 

 granulosiis from all the species following.
