Length. 4,1 mm.; spire, 2,6 mm.; width, 2,6 mm.

South Australia. 35 miles South West of Neptune Islands.

Shell rather solid, whorls 8, rapidly increasing. Protoconch conical, smooth, sharp, 3 whorls, homostrophe. Varices solid, half the width of the interspaces, numerous, 20 on the body-whorl, tuberculate, 4 tubercles or prickles on the penultimate, 7 on the body-whorl, microscopically axially striate. Interstices very minutely closely spirally lirate, lira mounting the varices. Aperture round, with a shallow gutter at the junction of the basal lip and the columella, which is thus slightly twisted and toothed. The varices wind round the columella as 7 oblique plaits ceasing at the inner lip, which here is thin and erect.
