The length of the shell veries between 10 m- 11mm, its diameter between 4 mm-5 mm. (Original description in French) The small shell is somewhat elongated and swollen below. It is composed of six to seven
whorls adorned with narrow, prominent ribs that extend to the suture. These ribs are covered with close-set, rough striae, except on the upper part of each whorl, which is smooth. The
aperture is almost oval, with a very short
siphonal canal, and a few slight folds can be observed on the inner part of the outer
lip, which shows a strong external ridge. ==Distribution==
