32 PKOCEEDINGS OF THE MALACOLOGICAL SOCIE'lT. 



Suture canaliculate. Aperture oblique, ovato-semilunar, extended 

 beyond the body-wborl by a broad, white, flat, and slightly sunken 

 callosity. Peristome very thick and rounded ; columella very short. 

 Diam. '7, height 1'2 mm. 



Hob. — Maloney's Reef, Hauraki Gulf, type (H. S.) ; Lyall Bay, 

 Cook Strait (H. S.) ; Titahi Bay, Cook Strait (Miss M. Mestayer). 



Named in honour of my friend Mr. Charles Hedley, of the 

 Australian Museum, Sydney, who informed me that he had discovered 

 the same species in Australian waters. With regard to sculpture this 

 is one of the most variable shells known to me ; all intermediate 

 grades between quite smooth and distinctly spirally ridged forms 

 occur, but the peculiarities of the aperture remain constant. Type in 

 my collection. 



29. Anabatheon gradattjm, n.sp. PI. Ill, Fig. 33. 



Shell very small, oval, gradate, rimate, solid, not shining. Sculpture 

 consisting of irregular fine axial plications, crossed by fine microscopic 

 spiral striae. Colour white. Spire conical, a little higher than the 

 aperture ; outlines convex. Protoconch small, papillate, of one and 

 a half convex and microscopically finely spirally Urate whorls. 

 Whorls 4, the last very large, shouldered above, angle not carinated, 

 slightly convex below ; base convex. Suture impressed. Aperture 

 oblique, oval. Peristome continuous, slightly thickened and expanded, 

 sharp, thin on the parietal wall. Columella short and arcuate. 

 Umbilical chink well marked. Diam. r6, height 2*25 mm. 



Hah. — Near the Snares Islands, in 50 fathoms (Capt. Bollons). 

 Type in my collection. 



30. RissoiNA Hanleyt, Schwartz. 



Rissoina Sanleyi, Schwartz: Die Familie der Rissoiden, 1860, p. 64, 



pi. iv, fig. 28. 

 R. fasciata, A. Adams: Suter, Proc. Mai. Soc, vol. iii, p, 7, not of 



Adams. . 

 Sab. — Bay of Islands, Hauraki Gulf (H. S.). 



Two specimens in the Canterbury Museum, collected by Mr. C. 

 Spencer, near Auckland, and determined by the late Capt. F. W. 

 Hutton as R. fasciata, A. Ad., are undoubtedly R. Hartley i, Schw. 

 The New Zealand specimens taken for R. fasciata by Angas and 

 Sowerby were no doubt varieties of R. rugulosa, Hutton, which is 

 nearly allied to the former. I am not aware that R. fasciata has ever 

 been found in New Zealand waters. 



31. RissoiisrA FuscozoNA, n.sp. PI. Ill, Fig. 34. 



Shell small, elongately oval, imperforate, thin, smooth, shining, 

 semitransparent. Fine oblique growth-lines form the only sculpture. 

 Colour fulvous, a dark-brown band below the suture ; peristome 

 fuscous. Spire elevated conic, twice the height of the aperture ; 

 outlines slightly convex. Protoconch small, flatly convex, smooth. 

 Whorls 5, convex, regularly increasing, the last high, rather ventricose 

 and slightly contracted below; base convex. Aperture oblique, oval,
