Tassell Albany Residency Museum, Albany, Western Australia Abstract One new genus and five new species of gastropods are described from the late Early Devonian Bell Point Limestone, on Cape Liptrap Peninsula, 150 km south-east of Melbourne. Six other gastropod taxa are recorded. The new genus Bassotrochus is assigned to the family Omphalotrochidae. Together with Orecopia murrayi sp. nov., also from the Bell Point Lime- stone, Bassotrochus angulatus sp. nov. represents the earliest known occurrence of this family to date. The other species are Tropidodiscus waratahensis sp. nov., Straparollus (Euomphalus) sp., ? Mourlonia sp., Gyronema bellense sp. nov., Murchisonia (Murchisonia) bassensis sp. nov., M. (Murchisonia) sp. A, M. (Murchisonia) sp. B and M. (Hormotomina) sp. Also described are Micromphalus clarkei (de Koninck) from near Yass, N.S.W. and an indeterminate form from the Waratah Limestone, Cape Liptrap Peninsula. This shallow water gastropod fauna occurs as both coquinite and non-coquinite assem- blages associated with a diverse invertebrate community which includes corals, stromatopor- oids, bivalves and brachiopods.

Initially it was found only in Corio Bay, but during the past fiveyears it has spread so that it now occurs throughout the western half of Port Phillip Bay. • Densities of Sabella in many parts of the bay remain low but densities are usually higher (up to 13/m2 ) in deeper water and they extend into shallower depths in calmer regions. • Sabella larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor in soft sediment . • Changes to fish communities following the establishment of Sabella were analysed using multidimensional scaling and BACI (Before, After, Control, Impact) design analyses of variance.

The redescribed type specimen of Horologium kokeni Perner, 1907 from the late Silurian (Ludlow) of Bohemia shows strong morphological convergence with the two Baltic species, but Kiaeromphalus is distinguished by its lower rate of whorl expansion and less oblique aperture.

  • The Following Notice to Mariners Is
    LOCAL NAVIGATION WARNING GIPPSLAND PORTS The following navigation warning is published for general information. AUSTRALIA - VICTORIA LNW NO.1 OF 2021 GIPPSLAND PORTS NAVIGATION ADVICE OCEAN ACCESS BAR CROSSINGS ARE DANGEROUS DATE: Tuesday 9th March 2021 PREVIOUS Local Navigation Warning No10 of 2018 is referred. NOTICE: DETAILS: A recent Marine Incident has occurred at McLoughlins Beach ocean access entrance highlighting the risks involved for vessel operators attempting to make passage through and across ocean entrance sand bars. Gippsland Ports is the Local Port Manager for 5 Local Ports; Each of the following ports is a recognised Bar Port. • Port of Corner Inlet and Port Albert • Port of Gippsland Lakes • Port of Anderson Inlet • Port of Snowy River (Marlo) • Port of Mallacoota Inlet. Only the Ports of Corner Inlet, Port Albert and the Gippsland Lakes (Lakes Entrance Bar) have recognised aids to navigation to guide the Mariner through and across their respective ocean entrance sand bars. The entrances to these ports remain open at all times, however sound local knowledge and favorable environmental conditions are required to make a safe passage. The Port of Snowy River (Marlo), Port of Mallacoota Inlet and Port of Anderson Inlet are dynamic in nature with ever changing channel configuration and depths. Ocean access can be closed off at Marlo and Mallacoota during times of drought. There are no aids to navigation to guide the mariner through and across their respective ocean entrance sand bars. Lake Tyers - Sydenham Inlet and Tamboon Inlet, all remain closed until sufficient back up of water creates an ocean access entrance.

Ordovician land plants and fungi from Douglas Dam, Tennessee. The Palaeobotanist 68(1–2): xxx–xxx. 1–33. Ordovician land plants have long been suspected from indirect evidence of fossil spores, plant fragments, carbon isotopic studies, and paleosols, but now can be visualized from plant compressions in a Middle Ordovician (Darriwilian or 460 Ma) sinkhole at Douglas Dam, Tennessee, U. S. A. Five bryophyte clades and two fungal clades are represented: hornwort (Casterlorum crispum, new form genus and species), liverwort (Cestites mirabilis Caster & Brooks), balloonwort (Janegraya sibylla, new form genus and species), peat moss (Dollyphyton boucotii, new form genus and species), harsh moss (Edwardsiphyton ovatum, new form genus and species), endomycorrhiza (Palaeoglomus strotheri, new species) and lichen (Prototaxites honeggeri, new species). The Douglas Dam Lagerstätte is a benchmark assemblage of early plants and fungi on land. Ordovician plant diversity now supports the idea that life on land had increased terrestrial weathering to induce the Great Ordovician Biodiversification Event in the sea and latest Ordovician (Hirnantian)
