This may prove to be only a variety of L. Reussiana, though presenting some apparently 

 strongly distinctive characters, such as the absence of the marginal puncta and of the 

 oral denticle. From L. labrosa (Ali/sidota labrosa), Busk (' B. M. C.,' pi. xcii), it appears 

 to be distinguished, not only by its habit, but also by the smoothness of the surface, and 

 the circumstance that the peristome is entire posteriorly.
