Translation.

One shell from Station 1 (Shark Bay) is white, the protoconch whorls brownish, of 4½ whorls with a spiral keel and axial riblets; the following 6 whorls slowly increase in size and have two tubercled cords at the beginning, which later become three; the base is rounded, with three threads; aperture rather narrow, with an acute angle on the upper part. Height 2.6 mm, diameter 0.8 mm.

Diagnosis.

Lectotype height 2.6 mm. Shell pupoid, with flat whorls. Teleoconch of six whorls, which have three tubercled spiral cords. The second cord develops later and is fully visible from the fourth row. A fine suprasutural smooth cord also present. The last whorl has a fourth weakly tubercled spiral cord. The base has two more spiral cords: one is weakly tubercled, while the other is smooth. Peristome with a posterior sinus. Multispiral apex of five whorls: the first is smooth, while the others bear a single strong keel and axial riblets. Teleoconch white, apex white to light brownish.
