Shell very regularly elongate-conic, subdiaphanous to milk-white. Nuclear whorls small, deeply obliquely immersed in the first of the succeeding turns above which the tilted edge of the last turn only is visible. Post-nuclear whorls slightly rounded, separated by constricted sutures, marked by numerous slender, wavy, subequal and subequally closely spaced spiral striatums, of which about 33 occur upon the last turn between the summit and the periphery. Periphery of the last whorl marked by a slender raised keel, decidedly angulated. Base short, moderately rounded, fiarrowly attenuated anteriorly to reenforce the columella, sculptured like the posterior portion of the whorls. Aperture ovate, very broad, slightly effuse anteriorly; posterior angle acute; columella very slender, evenly curved, closely appressed to the attenuated base, with a strong fold at its insertion which is barely visible when the aperture is viewed squarely. The type has 7 post-nuclear whorls and measures: Length 5.6 mm, diameter 2.8 mm. It and four additional specimens (Cat. No, 150565, U.S.N.M.) were collected by Rev. G. W. Taylor at Nanaimo, British Columbia.
