breit. Das Gehäuse ist sehr schlank mit ca. 20 Windungen. Auch die ersten Windungen sind erhalten, der Protoconch fehlt. Auf den ersten 4 Windungen sind 2 Spiralrippen erkennbar. Alle folgenden Windungen sind schwach konvex mit eingetieften Nähten und völlig skulpturlos. Die flache Basis ist an einer scharfen Kante winklig abgesetzt. Sie ist bedeckt mit mehreren kräftigen (aber nicht bandartig verbreiterten) Spiralrippen, zwischen denen je eine schwächere liegt. Die Mündung ist schlecht erhalten und anscheinend rundlich. Anwachslinien sind nicht erkennbar.
