Description

The size of an adult shell varies between 15 mm and 30 mm.

(Translation of the original French description) The slightly shiny shell is solid and has an elongated fusiform shape. The turreted spire is composed of 9 very convex whorls, subcarinated on their extremes. They are separated by a very marked oblique suture, covered with sigmoid growth lines, fine decurrent striae and large, wide and nodular oblique longitudinal folds, numbering 6 on each of the last two whorls. The body whorl measures half of the total height of the shell. It finishes in a long, narrow and slightly twisted siphonal canal. The elongated aperture is angular at the top. The columella is sinuated at the top, then a little oblique. The simple outer lip is sharp. The color of the aperture is a dirty, uniform white, but is slightly tinged with red on the end of the siphonal canal. The ground color of the shell is a white uniform ivory.[3]

Distribution

This species occurs in the Atlantic Ocean between Gabon and Angola.

gollark: Which you can do by checking which properties are there or something, which is flaky.
gollark: You have to be able to detect if an object is an AType or BType.
gollark: Imagine you got a list containing both ATypes and BTypes and want to display a list of them or something. The logic for each is somewhat different because they represent slightly different entities.
gollark: You could just have a "thing type" field in them but then you're just doing tagged unions in an indirect way.
gollark: If you want, say, a list of AType values and BType ones, TS has *un*tagged union types for that, but you then have to do stupid stuff to discriminate between them.
