Descrição original:

(Dall, 1910): “Shell stout, wide, conic, with a smooth nucleus of about two whorls and four subsequent whorls; for somewhat over two whorls the young shell has a prominent keel against which the suture is closely apprcssed, so that the presence of tin 1 keel requires close examination to recognize; a little beyond the end of the second whorl the keel disappears below the suture, and only very obscure traces of it remain on the last whorl;

The spire as a whole is convexly conic, the separate whorls project but little; the last whorl rapidly enlarges with a rounded periphery, evenly rounded into a wide subcylindric umbilicus; sculpture of well marked retractively arcuate wrinkles, with subequal interspaces obsoletely spirally striate;

The sculpture is most obvious on the spire and on the part of the last whorl behind the periphery: toward the aperture the whorl descends a little below the periphery; the well-reflected outer lip bends markedly toward the posterior end of the pillar lip, and the two are joined by a thin glaze over the body; the pillar lip is very broad and thin. half obscuring the umbilicus; the pillar is straight without any twist or fold; the color of the shell is yellowish white, with more or less distinct pale brownish spiral lines or narrow bands; the lip is whitish, the interior of the aperture pale yellowish-brown; the nucleus is slightly mammillary.

Height of shell, 36 ; of last whorl. 10: of aperture (vertical), 13; maximum diameter of shell, 20; of aperture, 11: of umbilicus, 2.5 mm.”
