I0024 NUMBER 2 263 AUGUST i8, I 966 Notes on Shell Morphology and Classification of the Siliquariidae (Gastropoda) The Protoconch and Slit of Siliquaria squamata Blainville BY STEPHEN JAY GOULD1 INTRODUCTION More than 100 individuals of the curious slit worm-snail Siliquaria squamata Blainville were found embedded in a single sponge dredged from a de-jth of 300-400 fathoms in waters southeast of St. David's Light, Bermuda, on July 12, 1964. These specimens, including several that have retained the previously undescribed protoconch of the genus, represent the first reported occurrence of Siliquaria in waters near Ber- muda. Dall (1889, p. 260) doubted that S. squamata lives in sponges, but the Bermuda specimens affirm earlier suspicions of a sponge habitat. A specimen of S. squamata, showing characteristic slit length and erratic coiling, is shown in figure 1. ACKNOWLEDGMENTS Specimens were kindly made available to me by Dr. F. Mackenzie of the Bermuda Biological Station (S. squamata) and Dr. W. K.

    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

Aceptado el 5-VII-2003 ABSTRACT Among the biological material collected during the 1998-2001 “INVEMAR-Macrofauna” campaigns aboard the R/V Ancón along the upper zone of the continental slope of the Colombian Caribbean, at depths ranging from 200 to 520 m, a total of 104 gastropod species were obtained. Besides 18 not yet identified species, but including one recently described new species ( Armina juliana Ardila and Díaz, 2002), 48 species were not pre - viously known from Colombia, 18 of which were also unknown from the Caribbean Sea. Of the 36 families represented, Turridae was by far the richest in species (26 species). An annotated list of the taxa recorded is provided, as well as illustrations of those recorded for the first time in the area.

    Nearshore Marine Biodiversity of the Sunshine Coast, South-East Queensland: Inventory of molluscs, corals and fishes July 2010 Photo courtesy Ian Banks Baseline Survey Report to the Noosa Integrated Catchment Association, September 2010 Lyndon DeVantier, David Williamson and Richard Willan Executive Summary Nearshore reef-associated fauna were surveyed at 14 sites at seven locations on the Sunshine Coast in July 2010. The sites were located offshore from Noosa in the north to Caloundra in the south. The species composition and abundance of corals and fishes and ecological condition of the sites were recorded using standard methods of rapid ecological assessment. A comprehensive list of molluscs was compiled from personal observations, the published literature, verifiable unpublished reports, and photographs. Photographic records of other conspicuous macro-fauna, including turtles, sponges, echinoderms and crustaceans, were also made anecdotally. The results of the survey are briefly summarized below. 1. Totals of 105 species of reef-building corals, 222 species of fish and 835 species of molluscs were compiled. Thirty-nine genera of soft corals, sea fans, anemones and corallimorpharians were also recorded. An additional 17 reef- building coral species have been reported from the Sunshine Coast in previous publications and one additional species was identified from a photo collection. 2. Of the 835 mollusc species listed, 710 species could be assigned specific names. Some of those not assigned specific status are new to science, not yet formally described. 3. Almost 10 % (81 species) of the molluscan fauna are considered endemic to the broader bioregion, their known distribution ranges restricted to the temperate/tropical overlap section of the eastern Australian coast (Central Eastern Shelf Transition).

Discussion 215 Acknowledgements 217 References 217 The newly discovered Campanian species Vermetus nielseni n. sp., Desbruyeresia antigua n. sp. and Litiopella schoeningi n. gen. n. sp. are described and the taxonomy of these gastropod groups is reassessed. Based on their protoconch morphology and radula characters, the Dendropominae, Provannidae, Litiopidae and Sculptifer are considered as related taxa within the Cerithioidea. They are interpreted to have arisen from a common ancestor that lived during the Cretaceous, apparently parallel to the radiation of the Vermetidae.

Basierend auf der Morphologie ihrer Protoconche und Radulae werden die Dendropominae, Provannidae, Litiopidae und Sculptifer als verwandte Taxa innerhalb der Cerithioidea angesehen, die sich wahrscheinlich aus einem gemeinsamen kretazischen Vorfahren entwickelten. Die Entwicklung dieser Gruppe verlief offensichtlich parallel zur Radiation der Vermetidae, deren Vertre- ter jedoch eine andere Protoconchmorphologie zeigen. Vermetids are sessile marine gastropods with a tubular shell that is irregularly coiled and totally or partly cemented to hard substrates.

Identification of these sponges, however, was made difficult by the absence in some specimens of key diagnostic characters, such as megascleres. We used an integrated approach to the taxonomy of these sponges, incorporating morphological examination by SEM, analysis of DNA sequence data (using the COI barcoding fragment of mtDNA) and preliminary studies of the chemistry of the sponges, to describe the new species, which were found to contain no native spicules other than acanthose mi- crorhabds. Here, we propose two new species of Theonella Gray, 1868: Theonella deliqua n.

A Late Oligocene (Chattian B) mollusc fauna from the clay-pit of Galten Brickworks at Norre Vissing, Jylland, Denmark. — Meded. Werkgr. Tert. Kwart. Geol., 24(3): 193-224, 3 figs, 1 tab., 2 pis. Leiden, September 1987. A rich Late Oligocene mollusc fauna from Norre Vissing near Skan- derborg Qylland, Denmark) was studied. The locality and the exposed described in the litho- sequence Eire detail, and and biostratigraphical positions are discussed. A list of the mollusc species is given, and com- parisons with other Danish and German faunas of Late Oligocene age are made. In the discussions several and systematical part on species are given five new species are introduced, viz. Solariella (Solariella) vissingensis n. sp., S. (S.) ronaldjansseni n. sp., ?
