less, the walls rather thick and scarcely translucent. The 

 spire, which terminates in an obtuse apex, consists of 7 rather 

 convex whorls separated by an impressed suture, and becom- 

 ing rather high below. The last whorl is the broadest, nar- 

 rowed below without a carina. Aperture almost round, red- 

 dish-yellow, rather large, with 6 rather strong teeth, of which 

 2 are in the palate, 2 on the parietal wall and 2 on the colu- 

 mella. The peristome is only slightly thickened, somewhat re- 

 flected towards the umbilicus only, the insertions approaching 

 somewhat, the outer one joined with the upper fold of the 

 parietal wall. Length 2%, diam. 1% lines (Kuester, P. miihl- 

 feldtii) .

A markedly conic, chestnut-brown shell, of stouter figure 

 than shells of the phUippii group, and differing from avenacea 

 and its immediate allies by the more conic shape and by hav- 

 ing only two palatal folds, by the shorter angular lamella, etc. 

 It is a rather isolated species. 



Nomenclature. This species, usually known as Pupa muhl- 

 feldti or miihlfeldi K., has not been correctly designated dur-
