The shell is small (maximum length 14 mm) and fusiform. The spire is high and acute, consisting of one and three-fourths nuclear whorls and four or five strongly angulate postnuclear whorls. The suture is strongly impressed. The body whorl is long (but not broad) and fusoid. The aperture is small, entire, and subcircular, with a strongly erect and distally flaring peristome. Each anal siphonal tube originates nearer the earlier of its adjacent varices and sweeps anteriorly, dorsally, and counter to the direction of growth. The siphonal canal is moderately long, slender, closed, bent first to the left and then to the right, and weakly dorsally recurved.
The body whorl bears four sharp, relatively undeveloped varices. The leading edge of the upper portion of each varix bears a series of crescentic ruffles; at the base of the body the varix cuts sharply inward to merge with the right margin of the siphonal canal. Spiral sculpture is not apparent.
Shell color is purple-brown, under a thin, flat-white, axially striate intritacalx. The aperture is pale yellow-brown.
