Shells from station 100 (Francis Bay), 101 (Algoa Bay) and 106 (Agulhas Bank) are distinguishable from all the previous species by their pointy protoconch, composed of 5 embryonal whorls with two spiral keels and axial riblets; the shells are brown, long and conical, in total 11 whorls, of which the first whorls after the embryonal whorls have two rows of tubercles and the lower whorls 3 rows, the last one is barely wider, above the suture a smaller cord is visible. The base has further three smooth cords visible. Siphonal canal and aperture are damaged. Height 4.5 mm, diameter 1.25 mm.

Diagnosis
Lectotype height 4.5 mm. Shell conical, with flat whorls. Teleoconch of nine whorls, which have three tubercled broad spiral cords; the second one appears lately, on the fifth whorl. A fine suprasutural smooth cord is also present. The last whorl has a fourth smooth spiral cord, and the base has further three smooth spiral cords. The peristome of the lectotype has been rebuilt after breaking (there is a scar, likely due to a predatory attempt), hence it is not fully reliable. Nonetheless, the sculpture of the peristome seems not to bear bifurcating ribs. Multispiral apex of five whorls; a bit worn in the lectotype; nonetheless, it clearly bears two keels and fine axial riblets on the lower three whorls. Colour light brown, the first tubercled cord looks lighter, but colours may be faded, because the specimens were dead collected.

Remarks
This is the only species with planktotrophic apex described by Thiele from South Africa.
