[1] (Original description) The white shell is broadly ovate, carinate, spiralled, with a very short, blunt, scalar spire.

Below the keel the whole surface is scored with fine prominent rounded unequal threads, parted by broader intervals.

The shell contains five whorls, flattened or even slightly concave above, strongly keeled and angulated in the middle, of regular increase.

The body whorl is very large and ventricose, with an elongated but convex base and a very small aperture.

The inner lip is thinly spread on the body, with a small chink in front behind the columella, the edge of which is narrow and twisted, with two indistinct folds above it.
