Flinders Top Shell. Shell small, turbinate, narrowly umbilicate, rather thin, dull; colour yellowish, flecked with light brown maculations which tend to form indefinite radial stripes, and are more pronounced on the periphery; spire very short, sutures impressed; whorls four and a half, rounded, sculptured, with spiral lirae which are close and weak; last whorl rounded at the periphery; basal lirae more distant; aperture oval, outer lip simple, columella regularly concave; umbilicus very narrow. Holotype: diameter 3.8 mm., height 3.75 mm.

This species differs from Nanula tasmanica Pctterd, from Brown River, Tasmania, in being smaller and more depressed; the spire is much smaller and shorter in comparison with the body whorl
