[1] (Original description) The thin shell is short and broad, biconical, angulated, with small oblique riblets and spiral threads, and with a lop-sided, small-pointed snout.

Besides these, there are on the whole surface flatly rounded threads which are broad, coarse, and irregular on the base, crowded and narrow at the keel, broader, but faint and more regular, on the shoulder.

The aperture is rather small, rhomboidally pear-shaped, being pointed above, prolonged into the rather short and broad siphonal canal below, and having a blunt angulation in the outer lip and at the base of the columella.

Its edge, on leaving the body, retreats immediately to form the shallow rounded open sinus which occupies the shoulder below the suture.

It is convex on the body, with a bluntly angular concavity at the base of the columella, which is short, small, conical, unequal-sided, obliquely cut off in front, with a narrow rounded twisted edge.
