The length of the shell attains 13 mm, its diameter 5 mm. (Original description) The small shell is narrowly fusiform. The
spire is turreted. The shell contains seven or eight
whorls. It shows a strongly projecting rounded keel at middle on the spire-whorls, concave above and below, on the
body whorl a well-marked concave area below keel followed by a second keel less pronounced, anterior to this rather abruptly contracted. The
aperture and
siphonal canal are slightly longer than the spire. The
protoconch consists of about 1½ smooth whorls, the lower distinctly carinate,
apex blunt. The sutures are linear, margined above and below, variable, some examples indistinct.
Sculpture—spirals con sist of numerous fine lines on the keel and above and below it, indistinct in some specimens, on the body whorl usually more pronounced. The axials consist of growth lines only, variable in strength, arcuate between the keel and suture above. The aperture is small, ovate and produced into a long siphonal canal. The outer
lip is angled at the keel, thence concave followed by a convexity, and beneath this rapidly narrowing to the siphonal canal. The
columella is narrowly callused, straight in the middle portion, narrowing and slightly twisted to the left. ==Distribution==
