Vulpecula (Pusia) hedleyi, n. sp. Fig. 21. 



Shell small, shortly fusiform, sculpture minute. Colour 

 greyish- white, occasionally very faintly mottled with brown. 

 Whorls \\ 5, rather flattened ; spire short, conical, apex blunt ; 

 the last proportionally very large. Sutures lightly impressed. 

 Sculptured with minute spiral grooves and with irregular longi- 

 tudinal plications, the latter slightly more prominent at the 

 sutures. Aperture oblique, narrow and much longer than tin 1 

 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. 



1 1 ah. 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 assist- 

 ance. 



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 no1 infrequently prominenl 

 ami the nodules sometimes obsolete. Aperture ovate. Outer 

 lip slightly expanded, the margin occasionally feebly dentate : 

 anterior canal short and somewhat curved. Length, 51 mm. ; 

 breadth. 2*59 nun. 



Type in the ( lolonial Museum. 



Hah. Whangaroa Harbour (Mr. A. Hamilton). 



Occuis in lair numbers, and appears to be the smallest of 

 the genus recorded from New Zealand. 



Rissoa leptalea, n. sp. Figs. 23, 21. 

 Shell minute, subrimate, slender, smooth, and rather fragile. 

 Colour white, shining ami semi-transparent. Whorls 5, having
