Description

The length of the shell attains 11 mm, its diameter 4 mm.

(Original description) (The described shell is evidently not quite adult) The shell is fusiform, with a pyramidal spire and a short siphonal canal. The shell is thin, smooth, shining, yellowish-white with red-brown blotches in three more or less interrupted bands. The shell contains 9 whorls, of which about 2 form a smooth, convexly-whorled nucleus. The post-nuclear whorls are sharply angular. Their upper part is slightly concave and occupies about ⅔ of each whorl,. The sculpture consists of numerous, sharp axial ribs, 16 in number on the body whorl, with pointed tubercles at the angle, connected by a rather faint spiral..Moreover, there are very faint growth lines and spiral striae, more conspicuous on the base of the body whorl, especially on the ribs, and a few stronger ones on the siphonal canal. The aperture is oval, angular above, with a short, broad siphonal canal below. The peristome is broken, probably with very shallow sinus above. The columellar margin is concave above, directed to the left below along the siphonal canal, with a thin layer of enamel.[2]

Distribution

This marine species occurs in the Mozambique Channel and off Madagascar; also off Indonesia, New Caledonia, Papua New Guinea and in the Bismarck Sea.
