but hardly elevated. Whorls 2 ¾; strongly convex, periphery and base rounded. Suture prominent, at the bottom of a rather deep furrow which causes whorls to appear bluntly angled on upper surface. Aperture as in Z. lissa (Sut.) but even less angled above, as in this species peristome Fig. 1.—Elachorbis diaphana n. sp. : type. × 30. Fig. 2.—Zalipais parva n. sp. : type. × 45. Fig. 3.—Talopena sublaevis n. sp. : type. × 8. Fig. 4.—Turbonilla (Pyroglampros) blanda n. sp. : type. × 10. Fig. 5.—Laevilitorina micra, n. sp. : type. × 33. Fig. 6.—Laevilitorina cystophora n. sp.: type. × 34. Fig. 7.—Laevilitorina cystophora n. sp : paratype. × 22. is continuous and sharp and outer lip is advancing, thus producing sutural notch. Columella arcuate, hardly thickened. Umbilicus wide, more than one-third major diameter. Diameter, 0·6 mm.; height, about 0·3 mm. Type in author's collection. Two specimens; from seaweed-washings, Taieri Beach, together with Z. lissa (Sut.), which, however, is very much more abundant.
