Shell small, very slender, white, polished, with nine whorls, nepionic part three-whorled, compact, white, without varices; subsequent whorls convex, smooth, with (on the ninth) about fifteen varices, which are very thin, sharp, and when perfect show a small angle near the suture; whorls adjacent, with no basal cord or disk. Length, 4; maximum diameter, 1.2 mm. The shell is remarkable for its acicular form and small size. The specimen is somewhat defective, and the figure hardly shows the little angular projection near the suture, which is normal to the varices.
