Show 5 1 DR. J. C. COX ON NEW AUSTRALIAN LAND SHELLS. [Jail. w> A tine showy species combining the characters of Helix macleayi and Helix blomfieldi, and found, in company with the former, rather abundantly. 2. HELIX COXENI, sp. nov. (Plate III. figs. 2, 2 ai) Shell deeply, rather largely, and openly umbilicated, depressedly globose, very thin, translucent, light yellow-brown, irregularly striated with slightly raised waved striae, irregularly studded with numerous sharp, rather long, fine recurved bristles; whorls 5_, last rapidly increasing in size, a little descending in front, and considerably inflated; aperture broadly oval, anterior margin scarcely everted, posterior broadly everted ; columella much dilated, slightly covering the umbilicus, and produced beyond it ; margins joined by a thin callus. Diameter, greatest 0*97, least 0*70 ; height 0*63 of an inch. Hab. Whitsunday Island, off Port Denison, Queensland. I have named this species after Mr. Coxen of Brisbane, an ardent and enthusiastic collector of our Australian shells. 3. VITRINA SUPERBA, sp. nov. Shell depressed, orbicularly auriform, light olive-green, rather opaque, shining ; whorls 3, convex, rapidly increasing, last much expanded ; spire scarcely raised, rounded, striated with lines of growth; aperture oblique, lunar-ovate, largely open; peristome simple, thin ; columella sharply arched ; margins widely separated. Diameter, gieatest 1*20, least 0*74 ; height 0*59 of an inch. Hab. Mount Dryander, Port Denison, Queensland. This fine species is, so far, the largest known. According to Reeve's figure it must closely resemble Vitrina magnifica, but is larger and more depressed. 4. HELIX BELLENGERENSIS, sp. nov. Shell deeply, rather narrowly umbilicated, turbinately depressed, lenticular, thin, dark claret-brown, not shining; whorls 5|, coarsely obliquely striated, very gradually increasing in size, last whorl rather sharply keeled at the periphery and depressed in front; base convex ; aperture rotundately lunar; last whorl suddenly contracted behind an everted peristome, which is white and slightly thickened ; margins approaching ; anterior margin inserted below the carina ; columellar margin only slightly dilated. Hab. Bellenger River, east coast of N e w South Wales. Diameter, greatest 0*55, least 0*48 ; height 0*35 of an inch. A simply lenticular species allied to H. leucocheilus, Cox, from which it differs in being more conical and more sharply keeled. 5. HELIX SARDA-LABIATA, sp. nov. (Plate III. figs. 3, 3 a.) Shell deeply, openly, rather largely umbilicated, orbicularly conoid, thin, smooth, very finely striated throughout, pale fawn-grev ; whorls 6, gradually increasing in size, the last sharply deflected*in front; aperture oval, margins closely approximating, slightly thick- |
