==Description==
The whitish shell has a conical shape with straight sides and a rather obtuse apex. The whorls of the protoconch are flat and orb-like. The teleoconch consists of five to six flat or slightly concave whorls with a somewhat angled periphery. The suture is well-marked. The growthlines are somewhat leaning forward with respect to the direction of the cone. The sculpture shows only fine microscopic spiral striae. The outer lip is straight adapically and gently curved towards the columella, which is nearly straight. The umbilicus is lacking. The columella has no tooth, but only an indistinct fold. 〔(J.J. van Aartsen, E. Gittenberger & J. Goud, Pyramidellidae (Mollusca, Gastropoda, Heterobranchia) collected during the Dutch CANCAP and MAURITANIA expeditions in the south-eastern part of the North Atlantic Ocean (part 2) )〕
