Shell attenuately fusiform, shining, white faintly tinged with chesnut, regularly transversely striate all over; whorls 6, flatly convex; aperture narrowly ovate, inner portion faintly thickened, outer lip thin. Long. 7, lat. 3 mil.
Habitat: Tasmania. Blackman's Bay.
A very distinct species from any form heretofore recorded from this island; the regular transverse striae is a character by which it can be easily recognised.

Shell dull white beneath a thin pale straw-coloured epidermis, mitneform, acuminate at both extremities. Embryo of two and one-half smooth convex whorls, of large increase; the tip is of a brown colour. Spire-whorls three and one-half, ornamented by revolving subacute ridges, approximately equal-sized and equidistant, at first five in number, increasing to eight on the penultimate. Body-whorl about three-fourths the total length, ornamented all over with revolving ridges, which are more rounded than those of the earlier whorls. Aperture narrow; columella very slightly arched, with two oblique plications (developed at the adult stage only); outer lip with a wide and shallow sutural sinus, smooth within but its margin minutely crenulated by the spiral lirae. Length 6, breadth 2.25 mm.
The form is that of a Conomitra, but having a sutural sinus and the columellar plaits not continued into the interior ; it simulates Mitrella, differing by the presence of folds on the columella.
