More turrited and slender than gravida., the embryonic 

 whorls not costulate, and the shell retaining very little dark 

 cuticle or none at any stage of growth. 



The embryonic whorls are finely, irregularly striate, but 

 not ribbed. The very pale yellow or nearly white cuticle is 

 somewhat glossy when unworn, and rarely shows a few 

 minute flecks of dark cuticle on the last whorl. The axis is 

 generally imperforate. Interior ivhite, the outer lip strength-

 The steeply ascending columellar lamella is rather strong. 

 The last whorl is sometimes weakly angular.

While it is closely related to L. gravida, yet there seems to 

 be no ^connecting specimens between the two species. L. 

 gravida is the more abundant and widely spread species. 



In the Cooke collection there is a set of four specimens, no.
