Show 640 MR. J. BRAZIER ON NEW AUSTRALIAN LAND-SHELLS. [Nov. 7, conoid, obtuse ; whorls 6, moderately convex, rapidly increasing, convex and inflated in front, slightly descending; umbilicus large, deep, and slanting ; aperture oblique, lunately ovate, interior of aperture of a bright flesh tinge ; peristome simple, white, straight; margins approximating and joined by a thin callus, right margin dilated, columellar margin broadly expanded and reflected, covering one third of the umbilicus. Diam. maj. 8, min. 6f, alt. 5 lines. Hab. Ipswich, Queensland, inland 50 miles from Brisbane: rare (coll. Brazier). I possess two specimens of this species, which approaches near to H. prunum, Fer., from Port Darwin and Port Essington, also to H.greenhilli, Cox, from the Dawson River. I have named it with great pleasure in honour of Dr. George Bennett, F.L.S., whose indefatigable exertions in the cause of science have made us acquainted with many new and rare specimens of natural history from Australia and the Polynesian Islands. 4. HELIX (TRACHIA) ENDEAVOURENSIS. Shell umbilicated, depressed, rather thin, very closely, regularly, and finely striated, shining, pale horny; spire rather prominent; suture slightly impressed ; whorls 5g, moderately convex, last roundly convex, inflated and deflexed in front; base convex and striated the same as the upper surface; umbilicus rather wide and deep ; aperture oblique, lunately ovate; peristome thickened and reflected, tinged with flesh-colour; margins approximating, right margin expanded, thin, straight, columellar margin reflected a little over the umbilicus. Diam. maj. 7, min. 5, alt. 3^ lines. Hab. Endeavour River, north coast of Australia (coll. Brazier). There is only one specimen of this species that I know of, and iii my collection ; it is of a much larger size than II. torresiana, Homb. et Jacq., and the sculpture is also very fine, whereas in the species of the French authors the sculpture is coarse. 5. HELIX (CAM.-ENA) AUREEDENSIS. Shell umbilicated, depressedly globose, rather solid, very finely obliquely striated, and, under the lens finely granulated, dark chestnut; suture ornamented with a fine white thread, and also a broad dirty white undefined zone round the umbilicus; spire broadly conoid, obtuse; whorls 6 to 6|, convex, the five upper whorls of a reddish chestnut, the last increasing in size, rounded and deflected in front; base convex; aperture diagonally ovately lunate, brownish white within ; peristome straight, ivory-white, slightly thickened and reflected ; margins approximating, right margin expanded, columellar margin arcuate and reflexed, concealing nearly half of the umbilicus, which is deep. Diam. maj. I1, min. 1\, alt. 1 inch. Hab. Aureed Island, Torres Strait, North coast of Australia (coll. Brazier and Hargraves). This species I have seen in some of the Australian collections |
