Laseron, 1954:
Shell minute, translucent, slenderly conical, of a few elongated rounded whorls with fine spiral sculpture. Protoconch short, flattened and smooth. No fasciole area distinguishable. Aperture short and narrow, outer margin simple, sinus deep, narrow and rounded on the shoulder, columella straight, canal short, wide and open.

Description by Powell, 1966:
Shell minute, 3.8-5.6 mm., thin, subcylindrical, with a long narrow body-whorl of almost two-thirds the shell height. Protoconch paucispiral, flattened on top and smooth. Aperture rather long and narrow, tapered to a very short, widely open and very shallowly notched anterior canal. Outer lip thin but with a deep U-shaped subsutural sinus. Adult sculpture of fine spiral threads, sometimes with the addition of a few faint axial plications. Colour of type species translucent amber, the apex purple tinged.

Except for the very distinct and well formed sinus the genus resembles a slender columbellid.

Range — Recent, New South Wales and Tasmania.
