Shell small, thin, semi-opaque, oblong-acuminate. Colour milk-white. Sculpture : everywhere finely, spirally grooved ; medially the grooves are almost effaced, posteriorly about half-a-dozen are deeply incised. Faint longitudinal growth lines are perceptible. The aperture is as long as the shell, posteriorly it narrows to a canal, anteriorly is broad and effuse. The inner lip terminates in a spike posteriorly. The columella forms at the base a broad auricular lobe, with a thickened edge. Neither umbilicus nor umbilical furrow are present. Length, 4 mm. ; breadth, 1 ,65 mm. The present is readily distinguished from other Australian Volvulellae by the sharp point of the posterior end.

Two shells from 63-75 fathoms off Port Kembla. There is a series in the Australian Museum dredged off Watson's Bay. I obtained it in 1901 in 15 fathoms off South Palm Island, Queensland, which gives the species a range of sixteen degrees of latitude.
