Spirals-on the last four whorls there are three, on the earlier two, rows of tubercles set upon the longitudinals, and slightly connected in each row by a fine thread; round the angle of the base runs a sharp rounded thread; at the top of the pillar is another finer; on the pillar itself there are two folds.</emphasis>

Teleoconch of 11 whorls with three spiral cords, the second as a narrow thread until the last whorl, with tubercles at the intersection with the prosocline axial ribs. A fourth smooth suprasutural cord is visible in the second half of the shell. Numerous prosocline growth lines are visible in the interspaces between the cords. Peristome with a shallow posterior sinus and additional spiral cords. Siphonal canal long. Base rather flat and concave with two additional smooth spiral cords. Protoconch incomplete in the
