* List of countries might not be complete


Shell small thin rotate, flat above, shallow concave beneath, sides perpendicular. Colour white. In its broken state there remain two whorls and the protoconch. Whorls almost square in section, with a keel projecting at the upper and lower corners. Sutures channelled. Sculpture : above, the upper outer keel stands up from the surface and is constituted by a double bead row ; latterly two smaller beads intervene between larger ones. A single narrow bead row runs along the inner margin close to the suture. On the base a single broad elevated bead row forms the outer keel and a narrower row runs along the inner margin. On the side are three evenly spaced raised threads. The space between the bead rows is transversely striated by growth lines. Protoconch tilted, but not sufficiently so to conceal the whorls either from above or from below. Major diam., 4,5 mm.; minor diam., 3,6 mm. ; height, 1,25 mm.
