(Original description) The cylindrical shell is elongated, thin and fragile.

The shell consists of four whorls growing fairly quickly and barely convex.

This edge projects forward by describing the curve of a fairly large circle.

It attaches quite high on the penultimate turn, which deflects the last portion of the suture backwards.
