Shell small, 9 mm., claviform, with a tall pagodiform spire, and an ovate body-whorl, tapered to a short rather deeply notched anterior canal. Protoconch, according to Cossmann (1903) of about 2,5 carinate to bicarinate but otherwise smooth whorls. Adult sculpture of rather prominent narrow spiral cords, 2-3 on the spire whorls, the first at or below the middle and the third emergent at the suture, over the last two whorls. Body-whorl with 12-14 cords. The shoulder slope is straight, steeply descending and wide. Sinus not clearly shown in illustrations but evidently broadly shailowly arcuate and occupying most of the shoulder slope. There is a surface sculpture of thread-like axials, most prominent over the shoulder slope, where they are crossed medially by two or three fine spiral threads. The colour is described as brown with the aperture white within.

Shell small, attaining 12 mm, claviform, with high spire and elongate-ovate last whorl, terminating in moder¬ately long unnotched or shallowly notched siphonal canal. Protoconch 2,5 bicarinate whorls (type species) to conical multispiral with axial ribs. Teleoconch whorls weakly convex, subsutural ramp shallow, concave. Anal sinus moderately deep, U-shaped, with deepest point slightly above shoulder. Axial sculpture limited to crisp growth lines. Spiral sculpture of distinct, narrow, widely spaced spiral cords. Aperture moderately high, narrow oval.Operculum present, small, with terminal nucleus.Odontophore absent. Radula of long, slightly curved, hypodermic, pointed marginal teeth with very weak blade.

There is a superficial resemblance to Teretia in the adult facies, but that genus is daphnellid, with a polygyrate diagonally cancellate protoconch, and a deep reversed L-shaped sinus.
