(Described as Acteon austrinus) The small, thin shell is ovate. It is strongly striated, with a high conical
spire, a blunt tip, and a tumid
body whorl.
Sculpture : Longitudinals: the lines of growth are very faint and somewhat markedly oblique. Spirals: the whole surface is scored with strong equal furrows which are about half the breadth of the interstices. These furrow are not stippled, but are delicately and regularly cut across on the lines of growth by fine threads. There are about 20 of these furrows on the body and about 9 on the penultimate whorl. The colour of the shell is porcellanous, with a glossy surface. The rather high spire is conical and subscalar. The
protoconch is rather large, blunt and flattened. It has a very slight inversion of the extreme tip. There are nearly five
whorls, very little convex. The body whorl is rather large and somewhat tumid. The slight suture is rather oblique and scarcely impressed. The
aperture is oval, pointed above and a little oblique in its direction. The outer
lip is sharp and thin, with its edge crenulated by the sculptural spirals. In direction it is straight above, well curved on the base, where it is very slightly emarginate. The inner lip is very slightly convex on the body. It passes gradually into the short concave
columella, at the base of which there is only the faintest trace of a tooth. Its edge is sharp and patulous, with a minute chink behind it. ==Distribution==
