Description

The size of the shell varies between 23 mm and 40 mm. The solid, umbilicate shell has a conical shape. It is black or purplish. The elevated spire is conical. The about six whorls are somewhat convex, and nearly smooth. The body whorl is more or less angulate at the periphery, sometimes obtusely bicarinate. The oblique aperture is rather small. The columella is arcuate, spreading above in a white callus. The umbilicus is white within, somewhat funnel-shaped, bearing a spiral rib which terminates in a denticle in the middle of the columella.[3]

Distribution

This species occurs in the Pacific Ocean off Peru to Chile.

gollark: IIRC they had to invent a grade even higher than A* once.
gollark: Yeeeees, it's quite bad.
gollark: And they do predicted grades for university applications (the timing is stupid).
gollark: Also, teachers have incentives to try and increase grades.
gollark: Instead of setting questions posing problems to solve, a past exam paper I looked at literally had a question asking you to match up "procedural abstraction" and "problem decomposition" and such with definitions.
