The columellar margin is patulous, a little reverted, scarcely twisted, with a broad deep sinus above, a strong, but not sharp, twisted tooth projecting at about three-fourths of its length, below which is a smaller sinus running out into a point at the extreme end of the columella. The umbilicus is large, funnel-shaped, and deep. It is sharply defined by the edge of the base, the spiral of which runs out to the point of the columellar margin. Within the umbilicus is a strongish undefined spiral furrow answering to the columellar tooth, and the lines of growth are strongly defined. This species occurs in the Atlantic Ocean off the Azores and in the Gulf of Mexico, off Puerto Rico.
