 covered with a black fugacious epidermis, dense on the last whorl, 

 more sparsely distributed on the upper whorls, worn off in front of 

 the aperture; apex dark brown; whorls 7, convex; suture well im- 

 pressed; aperture oval, a trifle oblique, white within with a pur- 

 plish tinge; peristome acute, slightly thickened within, edge dark 

 purple; columella purplish white, flexuous, abruptly terminating

Unlike most of the Amastra [sic], which generally have dark 

 dingy colored animals, this species has a beautiful, almost white 

 animal. The after portion and edges of the foot under a lens are 

 seen to be closely studded with minute pink spots which give 

 these parts a delicate pink hue. — Bald.
