Description

The length of the shell attains 27 mm, its diameter 8 mm.

(Original description) The shell contains 12 whorls, excluding the (defective) protoconch. It is pale brown, acute, with an inconspicuous suture. It shows eight or nine prominent axial ribs with equal or wider interspaces and faint incremental lines. The anal fasciole is wide, constricted, a single strong cord and fine spiral threads between it and the suture. In front of the fasciole are about six strong cords slightly swollen as they override the ribs, with much wider interspaces occupied by fine spiral threads, the cord at the periphery stronger than the rest. The base shows threads of intermediate size, close-set. The outer lip is sharp, arcuate and undulate by the ends of the spiral cords. The anal sulcus is short, pear shaped with no subsutural callus. The body throat and the columella are white and smooth. The short siphonal canal is recurved.[2]

Distribution

This marine species occurs from the Gulf of California to Colombia

gollark: Excellent. I found a more performant thingy.
gollark: Okay, so does anyone know if there are tab managers which will *not* break with 700 tabs (what is it *doing*? 700 isn't a big number).
gollark: Maybe you're just apioform.
gollark: Oh no. "Tab Manager Plus" is not equipped for my sheer tab count.
gollark: Wow, back up to 720!
