Translation.

One shell from station 25 (Shark Bay) is slender, brown, with 15 whorls which slowly but regularly increase in size, the protoconch has a single spiral keel and axial riblets; the following teleoconch whorls have two rows of tubercles, a third row develops between the first and second row, which gradually becomes stronger on lower whorls; on the base there are two smooth spiral cords. Height 4.3 mm, diameter 1 mm.

Diagnosis.

Holotype height 4.0 mm. Shell conical. The teleoconch has nine whorls, with three tubercled spiral cords; the second cord develops later along the spire and is well visible only on the penultimate whorl. A fine suprasutural smooth cord is also present. The last whorl has a fourth smooth spiral cord and the base has one further smooth cord. Peristome missing. Also the protoconch is incomplete, but clearly multispiral; on the three visible whorls there is a single sharp keel and axial riblets. Colour brown, the first row of tubercles is lighter, almost grey.
