L^rv l-^C The responsibility of the statements and opinions in the following papers and discussions rests with the individual authois and speakers ; the Society merely places them on record. f ROYAL SOCIETY OF TASMANIA The Royal Society of Tasmania was founded on the 14th October, 1843, by His Excellency Sir John Eardley Eardley Wilmot, Lieutenant Governor of Van Diemen's Land, as "The Botanical and Ilorlicultural Society of Van Diemen's Land." The Botanical Gardens in the Queen's Domain, near Hobart, were shortly afterwards placed under its management, and a grant of £400 a year towards tlieir maintenance was made by the Government. In 1844, His Excellency announced to the Society that Her Majesty the Queen had sij^nil'ied her consent to become its patron; and that its designation should tlienceforward be "The Royal Society of Van Diemen's Land for Horticulture, Botany, and the Advancement of Science." In 1848 the Society established the Tasmanian Museum; and in 1849 it commenced the publication of its "Papers and Pro- ceedings." In 1854 the Legislative Council of Tasmania by "The Royal Society Act" made provision for vesting the property of the Society in trustees, and for other matters connected with the management of its affairs. In 18."j5 the name of the Colony was changed to Tasmania, and the Society then became "The Royal Society of Tasmania for Horticulture, Botany, and the Advancement of Science." In 1800 a piece of ground at the corner of Argyle and Mac- quarie streets, Hobart, was given by the Crown to the Society as a site for a Museum, and a grant of £3,000 was made for the erection of a building. The Society contributed £1,800 towards the cost, and' the new Museum was finished in 18Gl2. In 1885 the Society gave back to the Crown the Botanical Gardens and the Museum, which, with the collections of the Museum, were vested in a body of trustees, of whom six arc chosen from the Society. In consideration of the services it had rendered in the promotion of science, and in the formation and management of the Museum and Gardens, the right was reserved to the Society to have exclusive possession of sufficient and convenient rooms in the Museum, for the safe custody of its Library, and for its meetings, and for all other purpose j connect- ed with it. In 1911 the Parliament of Tasmania, by "The Royal Society Act, 1911," created the Society a body corporate by the name of "The Royal Society of Tasmania," with perpetual succession. The object of the Society is declared by its Rules to b« "the advancement of knowledge." His Majesty the King is Patron of the Society; and His Excellency the Governor of Tasmania is President. — ROYAL SOCIETY OF TASMANIA PAPERS AND PROCEEDINGS, 1923 CONTENTS Vhi'a' Studies in Tasmanian Mammals, Living and Extinct.

The present specimens relate to the same find as that noted in our communication to this Society upon 13th June, 1921, when we detailed the characters relating to the humerus of Zaglossus harrissoni. Nototherhim mitchelli, Owen.—Female (?) animal. Our claim (1920, p. 24 and p. 107) that the plaster cast studied by Professor Owen, and practically elevated by him to the status of a type, was made from the skull of a female animal, is once more our theme, and the evidence is of some con- siderable interest. Of the animal to be studied, we have the nasal platform, some parts of the zygomatic arch, one tusk, the right upper maxillary with parts of four teeth in situ, and the fifth present, but detached. In addition to this, the atlas, axis, and third cervical are available to us—a most fortunate group of associated bones in view of the nature of our inquiry. We have given (1920, p. 81) a table of the calipered thicknesses of Nototherian nasal platforms, and to this we now add the following data: — N. MITCHELLI. Female. Male. Thickness of right nasal boss 47 mm. 60 mm. Thickness of left nasal boss 49 mm. 59 mm. Central thickness of nasal platform 17 mm. 25 mm. Thickness at base of nasal cartilage studs 18 mm. 22 mm Thickness midway between studs and nasal bosses 16 mm. 16 mn\ Width of nasal platform 160 mm. 175 mm. 2 STiniKS IN TASMANIAN MAMMALS. MVIM; ANI« KXTINCT. As far as it is possible to compare actual bones with a cast, these data agree very well with the skull case in ques- tion. In the item of total platform width, they agree exactly, since both give 160 mm. as a result. Again, the general all-round reduction in size agrees with what might be expected from a female animal's skull, when studied in terms of a male animal of the same species. The surface of the bone of this nasal platform is so well preserved that it is easy to note even minute, superficial markings, and we accordingly supplied a sketch illustrating the contours, and grouping of vascular scars, etc., the dia- gram, we opine, being self-explanatory. Upon the assumption that the female animals carried a less massive nasal horn than the males, it naturally follows that the cervical verte- bra would share in a dimensional reduction, and this is exactly what we find to obtain.

H. SCOTT AND CLIVIO lO. LOKI). F.I..S. 3 hold good. As to size, the specimen measures in total length, between verticals, 134 mm., and seems to be intact. As usual- ly obtains, the lower surface of the exposed area of the tusk is deeply excavated by the lower tusk, a sharply drawn cross line marking its point of contact with the second incisor (whose whole crown is generally excavated to the outline of the grinding surface of the mandibular tusk). GENERAL CONCLUSIONS. It would seem, therefore, that—as already suggested— the females of Nototheriuvi mitchelli wem fully armed and carried effective nasal horns, albeit less powerful than those of their mates. This conclusion is supported by the facts deduced from the study of the less solidly built nasal plat- forms, and weaker necks. That we are not here dealing with an immature male seems fairly assured, since the bones all suggest maturity, and the teeth have been well worn dur- ing the life of the animal. No feasible method of osteo- logical development seems capable of converting this, ap- parently, matured nasal platform, of 160 mm. in width, into one of 175 mm. or more, or of expanding the cervical verte- brae to the size commensurate to the aggressive nature of the male animal. As noted in our former communication the specimens were recovered, and sent to us by Mr.

    PHYLOGENY AND HISTORICAL BIOGEOGRAPHY OF LIMPETS OF THE ORDER PATELLOGASTROPODA BASED ON MITOCHONDRIAL DNA SEQUENCES TOMOYUKI NAKANO AND TOMOWO OZAWA Department of Earth and Planetary Sciences, Nagoya University, Nagoya 464-8602,Japan (Received 29 March 2003; accepted 6June 2003) ABSTRACT Using new and previously published sequences of two mitochondrial genes (fragments of 12S and 16S ribosomal RNA; total 700 sites), we constructed a molecular phylogeny for 86 extant species, covering a major part of the order Patellogastropoda. There were 35 lottiid, one acmaeid, five nacellid and two patellid species from the western and northern Pacific; and 34 patellid, six nacellid and three lottiid species from the Atlantic, southern Africa, Antarctica and Australia. Emarginula foveolata fujitai (Fissurellidae) was used as the outgroup. In the resulting phylogenetic trees, the species fall into two major clades with high bootstrap support, designated here as (A) a clade of southern Tethyan origin consisting of superfamily Patelloidea and (B) a clade of tropical Tethyan origin consisting of the Acmaeoidea. Clades A and B were further divided into three and six subclades, respectively, which correspond with geographical distributions of species in the following genus or genera: (AÍ) north­ eastern Atlantic (Patella ); (A2) southern Africa and Australasia ( Scutellastra , Cymbula-and Helcion)', (A3) Antarctic, western Pacific, Australasia ( Nacella and Cellana); (BÍ) western to northwestern Pacific (.Patelloida); (B2) northern Pacific and northeastern Atlantic ( Lottia); (B3) northern Pacific (Lottia and Yayoiacmea); (B4) northwestern Pacific ( Nipponacmea); (B5) northern Pacific (Acmaea-’ânà Niveotectura) and (B6) northeastern Atlantic ( Tectura). Approximate divergence times were estimated using geo­ logical events and the fossil record to determine a reference date.

He was educated at Launceston High School where he served as a prefect. In 1934 he won the Hemingway and Robertson Scholarship. 1 At that time he had completed a commercial course at Launceston High School and was proceeding further with accountancy studies. After leaving school Lloyd worked at D & W Murray wholesale and supply company in both Hobart and Launceston. He joined the 40th Battalion in 19392 and from May 1942 to November 1945 served with the RAAF attached to 90 and 92 Squadrons3. He became an instructor in the Central Flying School and from this time onwards flying became his life. On 12 April 1941 Lloyd Jones married Athalie Jean Flint of Hobart in Hobart. They had three daughters. Instrumental in forming the Southern branch of the Tasmanian Aero Club in 1945 he was subsequently appointed Manager and Chief Flying Instructor of the newly formed Aero Club of Southern Tasmania in 1948. An accident at Cambridge airport in July 1960 left him with serious injuries and curtailed his flying career. At that time he had clocked up 10,776 hours flying time. 4 An adventurous and skilled pilot, Lloyd Jones was the first photographer/pilot to take aerial photographs of the rugged mountains, lakes and beaches of South West Tasmania.

The mountain itself is named after its resemblance to a gold mining cradle. It has four named summits: In order of height: Cradle Mountain 1,545 mtrs (5,069 ft) Smithies Peak 1,527 mtrs (5,010 ft) Weindorfers Tower 1,459 mtrs (4,787 ft) Little Horn 1,355 mtrs (4,446 ft) When it was proposed to tackle Cradle Mountain on the 1st day of our week’s walking, Verna was heard to ponder the wisdom of such an attempt on the first day. As on a previous trip, when our group undertook to climb Mt Strzelecki on day one on Flinders Island, it took the remaining week to recover! Fortunately not many of our current party heard her. So off we set at 8.30am to climb to Kitchen Hut via the Horse Track around Crater Lake from our base at Waldheim Cabins (950 metres). It was not long into the walk when I, for one, was thankful to have gloves.

    CHANGES in SOUTHWESTERN TASMANIAN FIRE REGIMES SINCE the EARLY 1800S

    Papers and Proceedings o/the Royal Society o/Tasmania, Volume 132, 1998 IS CHANGES IN SOUTHWESTERN TASMANIAN FIRE REGIMES SINCE THE EARLY 1800s by Jon B. Marsden-Smedley (with five tables and one text-figure) MARSDEN-SMEDLEY, ].B., 1998 (31:xii): Changes in southwestern Tasmanian fire regimes since the early 1800s. Pap.Proc. R. Soc. Tasm. 132: 15-29. ISSN 0040-4703. School of Geography and Environmental Studies, University of Tasmania, GPO Box 252-78, Hobart, Tasmania, Australia 7001. There have been major changes in the fire regime of southwestern Tasmania over the past 170 years. The fire regime has changed from an Aboriginal fire regime of frequent low-intensity fires in buttongrass moorland (mostly in spring and autumn) with only the occasional high-intensity forest fire, to the early European fire regime of frequent high-intensity fires in all vegetation types, to a regime of low to medium intensity buttongrass moorland fires and finally to the current regime of few fires. These changes in the fire regime resulted in major impacts to the region's fire-sensitive vegetation types during the early European period, while the current low fire frequency across much of southwestern Tasmania has resulted in a large proportion of the region's fire-adapted buttongrass moorland being classified as old-growth. These extensive areas of old-growth buttongrass moorland mean that the potential for another large-scale ecologically damaging wildfire is high and, to avoid this, it would be better to re-introduce a regime oflow-intensity fires into the region. Key Words: fire regimes, fire management, southwestern Tasmania, Aboriginal fire, history.
