Description

The length of the shell attains 4 mm, the diameter 1.1 mm.

(Original description) The small shell is thin, slender and conical. Its colour is fawn with an opaque white zone median on the body whorl, and supersutural on the spire. Sometimes there is also a white subsutural band, the white being plainer on the ribs than on the interstices. The shell contains seven gradate whorls.

Sculpture  : the first three whorls are smooth, the remainder radially ribbed. The ribs are prominent, broad, vertical, spaced by about their breadth, continuing to the grooving at the base and to the aperture, discontinuous from whorl to whorl, amounting to fourteen on the body whorl. A slender subsutural cord connects the tops of the ribs. Beyond the ribs on the exterior extremity are eight, fine, spiral striae. The aperture is narrow, vertical, a little sinuous and contracted posteriorly. The inner lip shows a free elevate edge. The outer lip is simple. The siphonal canal is short and bent rather sharply backwards. [2]

Distribution

This marine species occurs off Tuamotu and North Queensland, Australia
