Menke attempted to separate from II. <///,///</ certain forms 

 under the name /.'. columellaris (Mai. Bl. 185-1, p. 26) ; these 

 shells, he claims, are mostly smaller than ampnfln, thinner, more 

 translucent, with narrower apical perforation ; the upper process 

 of the lip is broadly rounded "like the wings of a brooding hen ;" 

 the columella is flattened, and has a low projection. In the suite 

 before me I am unable to make the separation ho indicates, as the 

 characters seem to be too variable, and those he mentions are not 

 always correlated with each other.

Besides the difference in general coloring and the rose bordering 

 of the outer lip, there is a difference in shape between this species 

 and Bulla ampulla, the former being more compressed above the 

 center. (Sowb.).
