Perhaps L. regulare, Pfr.*, is nearer this species in some 

 respects than any other yet described. It is, however, con- 

 siderably smaller and has more numerous keels. It is also 

 taller in proportion to the width and has a rounder mouth. 



Besides the spiral keels in the present species, faint traces 

 of intermediate spiral stride are observable, and the lower 

 part of the body- whorl not unfrequently exhibits a slender 

 raised line at a little distance from the more pronounced 

 central carina.
