Shell depressly conical, openly but rather narrowly umbilica- 

 ted, thin pale horn-colour, semi-transparent, finely striated by the 

 oblique lines of growth, and sculptured with minute (almost 

 obsolete) spiral striation ; spire slightly convexly conical ; whorls 

 S% — ^ rather convex, separated by a simple well-impressed suture ; 

 last whorl indistinctly obtusely angulated round the middle, 

 slightly descending near the lip ; aperture oblique, roundly-ovate ; 

 peristome everywhere slightly expanded except superiorly, thin, 

 with the extremities somewhat inclining to each other, in the 

 columellar region white and expanded.

The nearest ally of this species is the preceding {H. conospira). 

 From it, however it differs in its less elevated spire, rather less 

 convex whorls, its slightly more open umbilicus and its larger size. 

 The spiral striation is very minute, and indeed scarcely observable 

 under a simple lens. The angulation of the body whorl is very 

 faint, but most apparent on that part of the whorl nearest the 

 upper termination of the peristome, the columellar portion of 

 which is considerably expanded at the point of juncture with the 

 last whorl, and is of a white colour.
