SPECIES CHARACTERISATION. — Small turriform shell. Protoconch heterostrophic. Three convex teleoconch whorls separated by a weakly impressed suture. Sculpture of two spiral cords on spire whorls, with numerous lamellar axial riblets in spiral interspaces. Last whorl with three spiral cords, abapical cord delimiting base, cords broaden and weaken abapically, base rounded, riblets weaken on last whorl, subobsolete. Aperture pyriform, no columellar fold.

DISTRIBUTION. — Lower Pleistocene: Atlantic, endemic to Selsoif (this paper).
