R. HOREI, Smith. PL 70, fig. 64b. 



Smooth, chestnut colored, with a white line beneath the suture ; 

 whorls 6, scarcely convex, suture simple, last whorl rising some- 

 what upon the preceding near the aperture, then suddenly descend- 

 ing, furnished with a slight basal thickening ; lip a little thickened, 

 especially towards the suture, somewhat patulous near the base.

Described as a doubtful Melanian. From the figure, it appears 

 to me to be not very distantly related to Melanopsis.
