THE MALACOLOGICAL SOCIETY OF AUSTRALASIA Inc. VICTORIAN BRANCH BULLETIN (Mailed to financial members of the Society within Victoria) Price 50¢ EDITOR Val Cram. Tel. No. 9792 9163 ADDRESS: 6 Southdean Street, Dandenong, Vic. 3175 Conus marmoreus Linne EMAIL: [email protected] VIC. BR. BULL. NO. 269 JUNE/JULY 2013 NOTICE OF MEETING The next meeting of the Branch will be held on the 17th June at the Melbourne Camera Club Building, cnr. Dorcas & Ferrars Sts South Melbourne at 8pm. This will be a Member’s night. Raffles & Supper as usual. There will be no meeting in July. A Bulletin will be issued prior to the August meeting which will be held on the 19th. At the April meeting we welcomed Caitlin Woods, PR Officer for the Malacological Society of Australasia. We discussed with her our role in the society and she offered any assistance she could to promote our branch to further the study of molluscs in Victoria. Jack Austin advises, with considerable regret, that he must dispose of his shell collection as his intended successor-grandson has opted for a volunteer career overseas and will not have a house in Australia for some years. Jack is a part-sponsor of this venture and will sell-off what he can of the collection to raise funds for his grandson. The collection is fairly extensive world-wide, about 7,000 lots, emphasising GBR, SE Australia, NT, Pacific lslands. All lots are registered - lists of families or places can be supplied.

Abstract Inversions of the origin of replication (ORI) of mitochondrial genomes produce asymmetrical mutational pressures that can cause artefactual clustering in phylogenetic analyses. It is therefore an absolute prerequisite for all molecular evolution studies that use mitochondrial data to account for ORI events in the evolutionary history of their dataset. -

Abstract Ghost shrimps of Callianassidae and Ctenochelidae are soft-bodied, usually heterochelous decapods representing major bioturbators of muddy and sandy (sub)marine substrates. Ghost shrimps have a robust fossil record spanning from the Early Cretaceous (~ 133 Ma) to the Holocene and their remains are present in most assemblages of Cenozoic decapod crustaceans. Their taxonomic interpretation is in flux, mainly because the generic assignment is hindered by their insufficient preservation and disagreement in the biological classification. Fur- thermore, numerous taxa are incorrectly classified within the catch-all taxonCallianassa . To show the historical patterns in describing fos- sil ghost shrimps and to evaluate taphonomic aspects influencing the attribution of ghost shrimp remains to higher level taxa, a database of all fossil species treated at some time as belonging to the group has been compiled: 250 / 274 species are considered valid ghost shrimp taxa herein. -
Ringiculid Bubble Snails Recovered As the Sister Group to Sea Slugs
www.nature.com/scientificreports OPEN Ringiculid bubble snails recovered as the sister group to sea slugs (Nudipleura) Received: 13 May 2016 Yasunori Kano1, Bastian Brenzinger2,3, Alexander Nützel4, Nerida G. Wilson5 & Accepted: 08 July 2016 Michael Schrödl2,3 Published: 08 August 2016 Euthyneuran gastropods represent one of the most diverse lineages in Mollusca (with over 30,000 species), play significant ecological roles in aquatic and terrestrial environments and affect many aspects of human life. However, our understanding of their evolutionary relationships remains incomplete due to missing data for key phylogenetic lineages. The present study integrates such a neglected, ancient snail family Ringiculidae into a molecular systematics of Euthyneura for the first time, and is supplemented by the first microanatomical data. Surprisingly, both molecular and morphological features present compelling evidence for the common ancestry of ringiculid snails with the highly dissimilar Nudipleura—the most species-rich and well-known taxon of sea slugs (nudibranchs and pleurobranchoids). A new taxon name Ringipleura is proposed here for these long-lost sisters, as one of three major euthyneuran clades with late Palaeozoic origins, along with Acteonacea (Acteonoidea + Rissoelloidea) and Tectipleura (Euopisthobranchia + Panpulmonata). The early Euthyneura are suggested to be at least temporary burrowers with a characteristic ‘bubble’ shell, hypertrophied foot and headshield as exemplified by many extant subtaxa with an infaunal mode of life, while the expansion of the mantle might have triggered the explosive Mesozoic radiation of the clade into diverse ecological niches. The traditional gastropod subclass Euthyneura is a highly diverse clade of snails and slugs with at least 30,000 living species1,2. -

INTRODUCCION La aportacion mas reciente sobre el genero Rissoella en Cuba y en el Caribe, es la realizada en un trabajo anterior (ORTEA & ESPINOSA [1]) en el que revisamos la taxo- nomia del genero en el Atlantico americano y describimos siete especies nuevas de estos microcaracoles, todas en las costas de Cuba. En dicho trabajo, establecimos dos grupos de especies, siendo el primero de ellos el que reune conchas con el ombligo abierto, sin cordo- nes ni aristas anteriores a el, cuyos animales pueden presentar o no una pigmentacion dife- rencial de la gonada y del digestivo, apreciable en las primeras vueltas de espira por trans- parencia de la concha; a este ultimo grupo es al que pertenece la especie que describimos a continuacion recolectada en el curso de una de las campafias de colecta realizadas en la peninsula de Guanahacabibes. -

^;^2_ MALACOLOGIA, 1993, 35(2); 261-313 PHYLOGENETIC RELATIONSHIPS AND GENERIC REVIEW OF THE BITTIINAE (PROSOBRANCHIA: GERITHIOIDEA) Richard S. Houbrick Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560, U.S.A. ABSTRACT The anatomy of seven members of the Bittium group is described, clarifying the status of the genus-level taxa comprising it. Bittium reticulatum, the type species of Bittium Gray, is described in depth, thereby establishing criteria for comparisons with other taxa of Bitliinae. The type species of Stylidium Dell and LirobiWum Bartsch, and representatives of Bittiolum Cossmann and Cacozeliana Strand are examined and compared with Bittium, s.s. Results of anatomical studies and a phylogenetic analysis using the Hennig86 and CLADOS programs, with Cehtt)ium as an outgroup, establish monophyly for Bitliinae Cossmann and reveal six different genus-level taxa. A new genus, ittibittium, from the Indo-Pacific, is proposed. Synonymies of each genus- level taxon and representative species examined are presented. Brief accounts of the ecology and zoogeography of each taxon are given. Two taxa formerly attributed to the 6/ff/um-group are herein excluded from it and referred to Cerithium Bruguière. These are Cerithium zebrum Kiener, 1841, and Cerithium boeticum Pease, 1861. The subfamily Bittiinae Cossmann, 1906, is thought to comprise nine genera (four of which were not included in phylogenetic analyses) : Bittium Gray, 1847; Bittiolum Cossmann, 1906; Ittibittium gen. n., Stylidium Dalí, 1907; Lirobit- tium Bartsch, 1911 ; Cacozeliana Strand, 1928; Argyropeza Melvill & Standen, 1901 ; Varicopeza Gründel, 1976; Zebittium Finlay, 1927. The genus Cassiella Gofas, 1987, of uncertain place- ment, is included as a possible member of the group. -

Page 1/19 Abstract Background Heterobranchia is a diverse clade of marine, freshwater, and terrestrial gastropod molluscs. It includes such disparate taxa as nudibranchs, sea hares, bubble snails, pulmonate land snails and slugs, and a number of (mostly small-bodied) poorly known snails and slugs collectively referred to as the “lower heterobranchs.” Evolutionary relationships within Heterobranchia have been challenging to resolve and the group has been subject to frequent and signicant taxonomic revision. Mitochondrial (mt) genomes can be a useful molecular marker for phylogenetics but, to date, sequences have been available for only a relatively small subset of Heterobranchia. Results To assess the utility of mitochondrial genomes for resolving evolutionary relationships within this clade, eleven new mt genomes were sequenced including representatives of several groups of “lower heterobranchs.” Maximum likelihood analyses of concatenated matrices of the thirteen protein coding genes found weak support for most higher-level relationships even after several taxa with extremely high rates of evolution were excluded.
