 whorl hardly one-third the total length, a little compressed 

 basally. Columella straightened, tapering to the base, hardly 

 truncate. Aperture vertical, semioval; peristome simple, the 

 margins subparallel, joined by a very thin callus ; right mar- 

 gin unexpanded, columellar margin a little reflexed, ap-

There is some diversity in the published figures of this 

 form. Bourguignat, who states that his figures were from 

 an example originally from Calcara, figures a narrower, more 

 cylindric form than Kobelt, measuring 6 x 1.75 mm., apert. 

 2x1 mm., whorls 6y 2 . His figures are copied on my plate 

 47, figs. 11, 12. Calcara gives the dimensions 3 x y 2 lines, 

 whorls 5. Kobelt's figures, copied on pi. 47, figs. 10, represent 

 a more conic form.
