[1] (Original description) The slender, fusiform shell is dirty yellowish, faintly banded with livid brown between the ribs near the top of the whorls, and stained with the same colour from the middle of the body whorl downwards.

The three whorls in the protoconch are convex, minutely reticulated with raised obliquely crossing lines.

The rest are very convex, with a slight concavity, sculptured with distinct arcuate short raised lines beneath the suture, also bearing slender oblique costellae (13 on the penultimate whorl), which are crossed by transverse lirae.

The aperture is narrow, occupying about four elevenths of the entire length.

The slender form, the delicate riblets, the shallow excavation at the upper part of the whorls, and their convexity are the principal distinctive characters of this interesting shell.
