Description The length of the shell attains 8 mm, its diameter 3 mm.
(Original description) The small, solid shell has a lanceolate shape. Its colour is dull cream, with a faint dorsal zone of brown. It contains 8 whorls, including a two-whorled protoconch. The radial sculpture is smooth and consists of round-backed perpendicular ribs truncated by a smooth and constricted fasciole, amounting to eleven on the penultimate whorl. On the earlier part of the body whorl these ribs are smaller and closer together than previously. Half a whorl behind the aperture is a rough varix, beyond which the ribs cease. The spiral sculpture on the base shows about a dozen fine grooves. Between the suture and the fasciole is a spiral ridge which tends to break up into beads opposite the ribs. The aperture is narrow. The sinus is C-shaped. A thick callus knob occurs at the right insertion. Hedley, C. 1922. A revision of the Australian Turridae. Records of the Australian Museum 13(6): 213–359, pls 42–56
