(Original description in French) The elongated shell is biconical, remarkable for the convexity of the upper whorls.

This striking convexity shows especially on the visible part of the penultimate whorl.

The inner lip contains at the base four very prominent, inclined plaits, of which the three lower ones are substantially equal to each other, the fourth is a little more stocky.

The shell has a very light fawn color with three bands a little darker on the body whorl.

[2] This marin especies occurs in the Atlantic Ocean off Madeira and the Canary Islands; also off Brazil.
