Description

The length of the shell attains 9 mm, its diameter 3.5 mm.

(Original description) The strong, fusiform shell has a rather long siphonal canal. it is light yellowish-brown, with faint red-brown bands, interrupted by the ribs. There is one rather broad band, just below suture, the second below the periphery, a third near the base of the body whorl. The base of the siphonal canal is likewise tinted. The shell contains about 7½ whorls, 2½ form the convexly-whorled protoconch, of which about the first whorl is smooth, the other ones are closely ribbed. The subsequent whorls are slightly convex, each with 7 continuous ribs, which have a small sharp point a little above the conspicuous, waved suture and are faintly crenulated, especially on lower part of the body whorl . The interstices are smooth, but for a faint spiral, connecting the costal points and a few spirals on the siphonal canal. The aperture is oblong, sharply angular above, with a rather long, narrow siphonal canal below. The peristome is not developed, probably with a shallow sinus above. The columellar margin is nearly straight, slightly directed to the left along the siphonal canal.[2]

Distribution

This marine species occurs off Java, Indonesia.
