Descrição:

(Pilsbry, 1902): “Shell rimate perforate, with the large umbilical area defined by an angle; subulate; whitish, becoming bluish-brown above. Surface lusterless, irregularly wrinkle-striate, the striae somewhat cut into granules by spiral impressed lines which are generally more prominent above. Spire tapering from the last whorl to the blunt, smooth, brownish-corneous apex. Whorls about 10, nearly flat, the last cylindrical, obliquely truncated below by a blunt but projecting angle, oner which the riblets do not pass, and which defines the umbilical tract. Aperture one-fourth the altitude, oblique, ovate, white inside. Outer lip acute, expanded and thickened within; columellar lip dilated above, vaulting over the minute perforation.”
