Abstract
NEW SOUTH WALES. Linnean Society, July 31.—Mr. J. H. Maiden, president, in the chair.—Further notes on supposed hybridisation among the Eucalypts: with the description of a new species, by Henry Deane and J. H. Maiden—Notes on the botany of the interior of New South Wales, part iv., by R. H. Cambage. The country particularly referred to comprises the district between Mount Hope and Parkes, the route traversed generally following the very low range which forms the watershed between the Lachlan and the Bogan Rivers. Mallees were found to be numerous near Mount Hope, but had ceased before Parkes was reached. Eucalyptus conica, Deane and Maiden, and E. albens were met with near Trundle.—Contributions to a knowledge of Australian Entozoa, part i., description of a new species of Distomum from the Platypus, by S. J. Johnston. Distomum ornithorhynchi, n.sp., is found in the stomach, duodenum and proximal portion of the small intestine of the duckbill. The species falls into Dujardin's subgenus Brachylaimus.—Revised census of the marine mollusca of Tasmania, by Prof. Ralph Tate and W. L. May. By far the greater number of the named species of Tasmania have been known by description only, covered by the papers of Tenison-Woods, 1875–81, and continued by Petterd and Beddome to 1884; and in consequence many of the species have been re-described under different names. The efforts of the authors, carried on for many years, are to bring these little known species into relationship with the constituents of neighbduring local faunas. The authors have had access to very nearly all of the local types, and their knowledge of the Australian fauna imparts to their interpretation of the Tasmanian species a value which may be accepted as correct in the main. The unfigured species, including about 30 new forms, number 120 or thereabouts, which are illustrated. Two new genera are established, Petterdella, based on Stylifer Tasmanica, T. -Wds., which has the general form and aperture of Rissoina and the heterostrophe nucleus of Eulimella; and Thraciopsis (nomen mutandum)=Alicia, Angas non Johnston (1861). A new species of a previously unknown genus in Australia, Cyamium, is described. Among some of the several changes in generic location is the transference of Comineila tenuicostata to Phos in a sectional group belonging to the Older Tertiaries of Australia. This is not the only instance of the survival of an Eocene genus in an unique species in the waters of Southern Australia and Tasmania. The number of species in the census of Tenison-Woods has been considerably reduced, but many extralimital species have been added. The total number is 676, grouped as follows:—Cephalopoda, 10; Gastropoda, 503 Scaphopoda, 4; Lamellibranchiata, 156: Palliobranchiata, 3.
