[Read before the Wellington Philosophical Society, 21st February, 1880.]

Up to the present time only two species of Vitrina have been recorded as indigenous to New Zealand.^* I have now to notice the discovery of a third; a large, highly polished, and really beautiful species.

Vitrina milligani, Pfr.

Shell depressly-ovate, rather solid, polished, very glossy, translucent, olive-black; spire convex; whorls three, second convex, last depressly-rounded; aperture more oblique than diagonal, lunately rounded-oval, within coloured as without; peristome simple; right margin dilated forwards, anterior regularly and columellar slightly arched. (Petterd).

Diameter, greatest, ·9 inch; least, ·6; height, ·4; aperture, ·6 inch long, ·4 broad.—South Karori (T. W. K.)
