was apparently intended to be lunate ; but, in consequence 

 of an inflection of the lip, beginning at about one third the 

 distance from the carina, it is rendered almost linear, and is 

 still farther contracted by three oblique, pliciform teeth, on 

 the inflected portion ; lip white, very slightly reflected. 



Diameter f of an inch ; height | of an inch. 



Very closely allied to H. Rangiana, Fer.

Testa albido-cornea, supra planulata, infra valde convexa, late et profunde umbil-

Description. 



Shell pale horn-color, shining, showing about four and a 

 half whorls above, which compose a nearly discoidal spire ; 

 suture distinct ; the last whorl somewhat channelled near the 

 periphery, which consists of a prominent, obtuse, compressed, 

 chestnut-colored carina, fully developed to the lip ; beneath, 

 greatly convex, descending suddenly into a broad, deep, 

 tunnel-shaped umbilicus, passing nearly through the shell; 

 surface faintly marked by the striae of growth ; aperture ren- 

 dered somewhat quadrangular by the junction of the lips and 

 the two angles at the keel, and the ridge at the umbilicus ; 

 lip white, reflected, commencing below the keel, then rising 

 to a level with it. 



Diameter | of an inch ; height less than | of an inch. 



Much like H. scahriuscula in form and aperture, but quite 

 different as to surface, color, and umbilicus.

Description.

 beneath, compressed, of a pale horn color, rather fragile ;
