Description

The length of the claviform shell attains 12 mm. The smooth protoconch consists of 1½-2 whorls. The teleoconch contains 5 whorls, convex from suture to suture (no concave sulcus). The suture is not distinctly crenulated, as in the other species in this genus. The sculpture consists of oblique opisthocline axial ribs, 11 on the first whorl, increasing to 12–13 on the body whorl, from suture to suture, and obsolescent on the base. The shell shows fine spiral striae 6–7 on the first whorl, increasing to about. 25 (between sutures) on the body whorl, crossing the ribs. No cingulum. The outer lip sinus is deep, with a thick, smooth parietal callus in the adult. The aperture is rather oblong. The straight columella is reflected at the short and broad siphonal canal. The color of the shell varies from white or lilac to orange.[2]

Distribution

This marine species occurs off Jeffrey's Bay - Northeast Cape, South Africa

gollark: I use `anyhow`, which allows me to magically store pretty much any error and add context to it and stuff, without having to have verbose conversion code.
gollark: This is because everything about it can fail at any time.
gollark: I feel like having convoluted `match` statements in my code for every operation would be very ææææ - in minoteaur there are sometimes even multiple `?`s per line.

gollark: Basically, if you use `?` on a `Result<T, io::Error>` your function must return `Result<T, io::Error>` (or something with an error type can store `io::Error`s).
