Shell small, with a very tall and slender spire, the whorls distinctly angled below middle whorl height, and again just above the lower suture. Protoconch papillate, blunt tipped of two whorls, the first smooth, the second delicately axially ribbed. The whole of the post nuclear surface is crowded with crisp, obliquely retractive axial lamellae. On the base, a third spiral emerges from just below the top of the aperture, making 3 keels on the body-whorl, the 2nd. and 3rd. being close together. Colour uniformly creamy-buff.
Height 5.7 mm., width 1.62 mm.

Shell small, turreted, imperforate, longitudinally finely laminated. Sculpture : Spire-whorls bicarinate, the slope uniform from the suture to the upper carina, situate on the lower half of the whorls ; the lower carina is less conspicuous, and close to the suture ; last whorl tri-carinate with the basal keel microscopically granulate, below this is a well-marked furrow bounded by a small concentric rib, which margins the columella ; on the lower part of the shoulder 2 indistinct spiral threads, more obscure on the upper whorls; the axial sculpture consists of oblique, close, delicate, undulating, and sharp laminations, extending over the suture, and terminating at the basal carina. Colour greyish-white. Spire elongate, turreted, sharply pointed, about four times the height of the aperture. Protoconch of 2 small rounded whorls, the nucleus with the initial half-turn smooth, the other half radiately delicately ribbed, the second whorl with sharp laminations. Whorls 10, regularly increasing, with straight sides above the keel, concave between the encircling ribs. Suture deep and channelled, which character is partly hidden by the axial laminae passing over it. Aperture ovate, angled above. Outer and basal lip rounded, slightly effuse, sharp, and with flexuous projections corresponding to the spiral keels. Columella concave, very little callous, terminating in a minute sharp point.
Diameter, 1-62 mm. ; height, 5-7 mm.
