Description

edit

The length of the shell attains 8.4 mm, its diameter 3.4 mm.

(Original description) The medium-sized shell is relatively stout. The whorls are strongly constricted. The protoconch consists of two and a half whorls, the last one bearing an obscure peripheral keel and sculptured with axial riblets.

The sculpture of the shell is reticulate, consisting of narrow axial ribs (10 to 12 on penultimate whorl), slightly curved on the anal fasciole, overridden by strong spiral threads (3 or 4 on penultimate whorl). In the interspaces lie microscopic frosted spirals. [2]
