Show 1875.] MR. BRAZIER ON NEW SHELLS FROM QUEENSLAND. 33 minutely granulated, shining, thin, dirty yellow; whorls 6, convex, suture impressed, the last whorl large, obtusely carinated at the periphery, base roundly convex, with the striae running into the deep funnel-shaped umbilicus; aperture oblique, ovately lunate, interior white ; peristome white, thickened, margins approximating and joined by a thin white callus, the right thin and descending below the centre, columellar reflected slightly over the umbilicus. Diam. maj. 14^, min. 13, alt. 10 lines. Hab. Johnson river, Queensland ; in the scrubs (coll. Brazier). I feel great pleasure in naming this shell after Mrs. Charles Coxen, a lady much interested in Australian natural history. 6. HELIX (HADRA) MOSSMANI, sp. nov. (Plate IV. fig. 6.) Shell imperforate, globosely turbinated, very faintly obliquely striated, exhibiting minute spiral lines and granulations (only seen under the lens), reddish yellow, with numerous spiral chestnut lines and bands ; spire conical, apex obtuse; whorls 6|, slightly convex, suture slightly crenulated; aperture oblique, ovately lunate; peristome black, reflected, margins approximating, the right descending at the upper part, columellar thickened, with a black callus round the umbilical region. Diam. maj. 19, min. 15, alt. 19^ lines. Hab. Dawson river, Queensland. This fine species comes near to Helix fraseri in its markings, but differs in being more turbinated, and in the lip being thinner. 7. HELIX (RHYTIDA) SHERIDANI, sp. nov. (PlateIV. figs. 7, 7a.) Shell umbilicated, conoidly globose, thin, closely, regularly and finely obliquely striated to the periphery, reddish chestnut; whorls 4£, moderately convex, the last large, flattened at the suture, base convex, showing faint, irregular, oblique lines from the periphery to the edge of the umbilicus, where they become more conspicuous; umbilicus wide and deep; aperture nearly vertical, roundly lunate, bluish within; peristome acute, margins distant, columellar a little dilated. Diam. maj. 13|, min. 11, alt. 8 lines. Hab. Cardwell, Rockingham Bay, N.E. Australia. I have named this species at the request of Mr. Coxen after his friend Mr. Sheridan, of Cardwell. 8. HELIX (XANTHOMELON) DAINTREEI. (Plate IV. fig. 8.) Shell umbilicated, somewhat depressedly globose, very thin, rugosely striated, minutely granulated, pale yellowish brown; spire conical, obtuse; whorls o\, convex, last large, inflated, base convex, nearly smooth; aperture oblique, lunate; peristome thickened, white, margins approximating, right descending in front, columellar reflected and partly covering the umbilicus. Diam. maj. 12, min. 9|, alt. 9| lines. Hab. Muggerbaa, Moreton Bay, Queensland. P R O C . Z O O L . Soc-1875, No. III. 3 |
