Remarks

This species has a multispiral protoconch although there is some variation in its number of whorls. It is uncommon on the Ibero-Moroccan shelf, where it is restricted to circalittoral hard bottoms. On Gorringe and Ampère, it is not so rare possibly due to availability of its preferred habitat. It was also recorded from Gorringe by Ávila and Malaquias (2003).
