Tube smooth without sculpture, colourless, dull. Aperture preceded by a slight swelling. The aperture is oblique in both ventral and lateral direction, being contracted on the left side. Surface with only oblique, fine growth lines. Septum domeshaped, granulated, with a broad nail-like mucro directed toward the right side. Macula large, illdefined, expanded, with a frosted appearance, clearly displaced to the left side. Juveniles rather different from adults, more conical and showing a clear dextral torsion. Larval stage not determined with certainty, probably with a multispiral protoconch. Periostracum light brown. Operculum, corneous, circular, multispiral, composed of a small central nucleus surrounded by an open spiral of 67 whorls. External side flat, internal side with a concave nucleus.</paragraph>
