Descrição original:

(Dall, 1893): “Shell when perfectly fresh with a delicate brownish epidermis, which is usually lost, beneath which the shell is brownish flesh color with irregular pale streaks in harmony with the incremental lines; the margin of the whorl in front of the suture is also often whitish; dead shells are Waxen or pure white, often with a ferruginous discoloration; whorls five and a half, the nucleus with a central pit or dimple at the apex, the first two turns regularly ribbed with small, sharp, rather distant ribs, the wider interspaces of which are spirally striate; subsequent whorls with close, fine, sharp, somewhat irregular wrinkles, in harmony with the incremental lines, sparser on the last whorl and crossed by fine sharp close strive of variable strength, sometimes hardly visible, but in other specimens distinct and granulating the wrinkles; all intermediate grades are observable in comparing many specimens; suture distinct; form like that of pallidior on a smaller scale, varying from moderately wide to slender; whorls rounded or moderately flattened; umbilicus small but deeper proportionately than in pallidior; aperture rounded ovate, the lip rather widely reflected, thin, the outer and pillar lips approximating, united by a thin wash of callus.”
