A very tliin species, peculiarly malleated. The labrum 

 arises from the middle of the impressed spire, is there 

 slightly thickened, but has no twist as in the typical forms 

 of the genus.

Ratlicr solid for so small a shell. The slight constriction 

 at the upper part of the body-whorl forms a solid crest above 

 it. The apical perforation is very small and deep — indeed, 

 narrower than the umbilicus, A very thin callus spreads 

 over the whorl, uniting the columella and the upper end of 

 the labrum.
