COX ON NEW LAND AND MARINE SHELLS. 565 throughout, very dark chestnut, lighter towards the apex, which is ornamented with very narrow spiral bands ; spire raised, bluntly conoid; whorls 7\, convex; margin of suture faintly lined with white below ; last whorl deflexed in front, base flattened ; umbilicus large, half closed by the reflexed expansion of the columellar margin ; aperture ovately lunate; margins much approximated, joined by a thin purple callus ; peristome everted, of a dark livid purple, as is also the interior of the aperture ; columella triangularly dilated. Diam., greatest 1*68, least 1*25 ; height 1*58 inch. Hab. Mount Elliott, near Port Denison, Queensland, North Australia. H E L I X ( C A M E N A ) C H A L L I S I , sp. nov. (Plate XLVIII. fig. 3.) Shell solid, heavy, umbilicated, depressedly orbicular, closely finely striated, of a waxy yellow colour, ornamented by six or more rather narrow dark chestnut bands of irregular sizes and distances apart, dark around the umbilicus ; spire moderately raised, bluntly convex ; whorls 7, convex, very gradually increasing in size, last shortly deflected in front; aperture ovately lunate, margins slightly approximating, joined by a thin callus, interior of aperture showing dark lines of ornamentation ; peristome straight, pure white, slightly thickened and reflexed, columellar margin triangularly expanded, half covering the rather narrow umbilicus. Diam., greatest 1*22, least 0*89 ; height 0*90 of an inch. Hab. L Island, Torres Straits (mus. Hargraves). The present adds another to the large number of species recorded of the Camcena type of Australian land-shells, most of them being extremely limited in their habitats, every island almost in Torres Straits possessing its own special species. H E L I X ( C O R A S I A ) B A L C O M B E I , sp. nov. (Plate XLVIII. fig. 4.) Shell imperforate, depressed, almost flat above, convex below, very thin, glossy, pale straw-coloured, coarsely striated above and below with regular oblique transverse striae, and longitudinally with strongly marked very slightly waved striae, giving by their decussation a granular appearance to the surface of the shell; spire scarcely raised, suture impressed; whorls 4, slightly convex above, rapidly increasing in size ; last whorl inflated below, and very prominently and sharply keeled, the keel edged with an opaque white line, base rounded; aperture large, subtrapezoidal, acutely angled at the periphery; peristome slightly thickened aud everted, upper margin attached to the carina of the last whorl; columella dilated, ap-pressed, and indented over the umbilical region. Diam., greatest 1*09, least 0*78 ; height 0*48 of an inch. Hab. Solomon Islands (mus. Hargraves). This species appears to be closely allied to H. (Caracolla) papyracea, Brod. H E L I X L E E I , sp. nov. (Plate XLVIII. figs. 5, 5a.) Shell with a large, open, funnel-shaped umbilicus, thin, translucent, globosely depressed, of a dark cinnamon-brown colour, |
