suture ; whorls 4^-, somewhat convex, the last convex at the base ; 

 umbilicus moderate and pervious ; aperture rotundately-lunar ; 

 peristome simple and straight, with the columellar margin very little 

 dilated and reflected. 



Diameter, greatest 1"12 ; least - 84 ; height 0*78 of an inch.

The above description is taken from Pfeiffer's Hon. If el. Viv., Vol. I., 

 p. 108, published in 1848. Subsecpiently, in 1859, he mentions in Sup- 

 plement IV. of same work, that his previous description of this species 

 was taken from an impei-fect specimen. In its adult state, he states 

 that, "it is extremely like H. Jervlsensis ; its greatest diameter, 22; 

 least 18; height 13^ mill. The right margin of the peristome is some- 

 what expanded ; the columella of a violet tint, and reflected over the 

 umbilicus. It differs from H. Jervlsensis in being a more solid shell, 

 by the more gradual increase of the whorls, and by the less inflation 

 of the last."

Reeve's figure represents three conspicuous spiral bands on the last 

 whorl. The above is simply a copy of Menke's original description 

 which Pfeiffer also copies.
