Vulpecula (Pusia) hedleyi, n. sp. Fig. 21. Shell small, shortly fusiform, sculpture minute. Colour greyish-white, occasionally very faintly mottled with brown. Whorls 4½–5, rather flattened; spire short, conical, apex blunt; the last proportionally very large. Sutures lightly impressed. Sculptured with minute spiral grooves and with irregular longitudinal plications, the latter slightly more prominent at the sutures. Aperture oblique, narrow and much longer than the spire. Lip uniformly curved and slightly thickened. Columella white, lightly callused and armed with four plaits, the anterior two more oblique; opposite the latter the columella is lightly swollen. Anterior canal short and broad. Length, 5.42 mm.; breadth, 2.63 mm. Type in the Colonial Museum. Hab. Whangarei Heads, dredged in shallow water (Mr. C. Cooper, of Auckland). Distinguished from other New Zealand species by the feeble longitudinal sculpture and short spire. I have much pleasure in naming this species after Mr. Charles Hedley, of the Australian Museum—a token of appreciation of his invariable kindly assistance. Trophon (Kalydon) curta, n. sp. Fig. 22. Shell small, ovate, rather solid, spirally and longitudinally ribbed, the latter strongest and forming prominent nodules on the lines of intersection. Colour whitish, occasionally a brown band on the base, rarely a few ill-defined scattered spots on the periphery. Whorls 6, lightly shouldered. Protoconch of two whorls, smooth except the last half-turn, upon which two small spirals arise. The sculpture consists of ten or eleven, rarely twelve, longitudinal ribs, narrower than the interspaces except when the latter number occurs, then equal or rather wider. Of the spirals there are two on the spire-whorls and six or seven on the last—occasionally three on the penultimate and eight on the last; the anterior spiral not infrequently prominent and the nodules sometimes obsolete. Aperture ovate. Outer lip slightly expanded, the margin occasionally feebly dentate; anterior canal short and somewhat curved. Length, 5.7 mm.; breadth, 2.59 mm. Type in the Colonial Museum. Hab. Whangaroa Harbour (Mr. A. Hamilton). Occurs in fair numbers, and appears to be the smallest of the genus recorded from New Zealand. Rissoa leptalea, n. sp. Figs. 23, 24. Shell minute, subrimate, slender, smooth, and rather fragile. Colour white, shining and semi-transparent. Whorls 5, having a somewhat loosely coiled, and those of the spire swollen, ap-
