Phylum MOLLUSCA Chitons, Bivalves, Sea Snails, Sea Slugs, Octopus, Squid, Tusk Shell
Phylum MOLLUSCA Chitons, bivalves, sea snails, sea slugs, octopus, squid, tusk shell Bruce Marshall, Steve O’Shea with additional input for squid from Neil Bagley, Peter McMillan, Reyn Naylor, Darren Stevens, Di Tracey Phylum Aplacophora In New Zealand, these are worm-like molluscs found in sandy mud. There is no shell. The tiny MOLLUSCA solenogasters have bristle-like spicules over Chitons, bivalves, sea snails, sea almost the whole body, a groove on the underside of the body, and no gills.

E-mail: [email protected] Abstract Three species in the gastropod genus Calliostoma are confirmed as living in Deep-Water Coral (DWC) habitats in the NE Atlantic Ocean: Calliostoma bullatum (Philippi, 1844), C. maurolici (Seguenza, 1876) and C. leptophyma Dautzenberg & Fischer, 1896. Up to now, C. bullatum was only known as fossil from Early to Mid-Pleistocene outcrops in DWC-related habitats in southern Italy; our study confirmed its living presence in DWC off Mauritania. A discussion is provided on the distribution of DWC-related calliostomatids in the NE Atlantic and the Mediterranean Sea from the Pleistocene to the present.

Calliostoma conulum, distribution area, Galicia, northwest Spain ABSTRACT. The Galician (NW Spain) population of Calliostoma conulum (Linnaeus, 1758) is analyzed, and it is confirmed that the species is rather common in this area.

INTRODUCTION Parenzan (1970), Nicolay & Angioy (1985), Sabelli, Giannuzzi-Savelli & Bedulli (1990), and represented Calliostoma conulum (Linnaeus, 1758) is mainly in Giannuzzi-Savelli, Pusateri, Palmeri & Ebreo known from the Mediterranean sea. It has been (1994). After Ghisotti & Melone (1971), the species is frequently confused or synonymized with other absent in the Black Sea, but it was recorded on the species.

Prosobranch Gastropods of Guam
Micronesica 35-36:244-270. 2003 Prosobranch gastropods of Guam BARRY D. SMITH Marine Laboratory University of Guam Mangilao, Guam 96923 U.S.A. email: [email protected] Abstract—Based on records from invertebrate collections at the University of Guam, specimens cataloged at other institutions, and the published literature, there are 895 species of prosobranch gastropods from Guam. The vast majority of the species are marine, but terrestrial and aquatic prosobranchs are included. Most the species recorded to date are conspicuous, epibenthic species from shallow reef habitats, but some species have been taken from depths up to 400 m. Microgastropods less than 7 mm in size have been poorly investigated to date. Comparison of prosobranch gastropods from Guam and Enewetak reveal that some 56% of the species occurring at Enewetak are found in Guam. Introduction Molluscs have been collected in Guam since the arrival of the earliest inhabitants (Thompson, 1945). Despite the long history of European contact with the island, scant attention was given to systematic investigation of the fauna until the collections of Quoy and Gaimard (1824–1826; 1830–1834). Hidalgo (1904– 1905) was the first to produce a catalog that included molluscs from Guam, but his emphasis was mostly on the Philippine Islands fauna. This catalog was followed by a series of unpublished lists produced by shell collectors and shell club members during the last several decades. Synoptic collections of molluscs from Guam and Micronesia were started by faculty of the University of Guam in the mid-1960s. These collections are housed in the Richard E. Dickinson Memorial Mollusc Collection at the University of Guam Marine Laboratory. -
Systematic Position of Basilissopsis and Guttula, and a Discussion of the Phylogeny of the Seguenzioidea (Gastropoda: Prosobranchia)
BULLETIN OF MARINE SCIENCE, 49(1-2): 575-598, 1991 SYSTEMATIC POSITION OF BASILISSOPSIS AND GUTTULA, AND A DISCUSSION OF THE PHYLOGENY OF THE SEGUENZIOIDEA (GASTROPODA: PROSOBRANCHIA) James F. Quinn, Jr. ABSTRACT The systematic position of the genera Basilissopis Dautzenberg and Fischer, 1897, and Guttu/a Schepman, 1908, is discussed; both genera are confirmed to be members of the Seguenzioidea Verrill, 1884. A preliminary phylogenetic analysis of that superfamily, based principally on shell characters, is presented. The analysis suggests that two subfamilies (fam- ilies) may be warranted: the Seguenziinae(idae) S.S., and the Guttulinae(idae) Goryachev, 1987. Three recent, major classifications ofthe Seguenzioidea are examined, with particular attention paid to the explicit or implicit characters on which those classifications were based. Assignment of the Seguenzioidea to the caenogastropod orders Littorinimorpha and Strom- biformes is rejected, Placement of the superfamily, as a suborder, between the Vetigastropoda and Archaeotaenioglossa cannot be confirmed or rejected based on the available data. The pointed tip of the protoconch, presence of sensory micropapillae on cephalic and epipodial tentacles, and presence of a right subocular peduncle are suggested as potential synapomor- phies with the Vetigastropoda. A compromise classification is proposed that would allow use of the taxa Archaeogastropoda and Vetigastropoda until more explicit statements of rela- tionships among the included superfamilies can be made. Recent discoveries of new gastropod taxa from deep-sea hydrothermal vent habitats, as well as re-examination and re-evaluation of previously known deep- sea taxa, have sparked renewed interest in the systematics, relationships, and phylogenies of "archaeogastropod" prosobranchs. In addition to the new animal morphologies, new, more comprehensive data sets and more stringent method- ologies for estimating phylogenies are being used. -

GEIGER Santa Barbara Museum of Natural History, 2559 Puesta del Sol, Santa Barbara, CA 93105, USA. E-mail: [email protected] Abstract The family Seguenziidae, including the genus Adeuomphalus, of the northeast Pacific are here revised. Seguenzia megaloconcha Rokop, 1972 is here synonymized under S. cervola Dall, 1919, S. quinni McLean, 1985 is here synonymized under S. gioviae Dall, 1919, S. catalina Dall, 1919 and S. certoma Dall, 1919 are synonymized under S. stephanica Dall, 1908. They represent either growth stages of one another, or are based on insignificant minor sculptural differences. A short commentary on the contraproductive proliferation of taxonomic data portals and the need for a single resource akin to GenBank is given. Introduction This contribution was started by the late James H. McLean as part of his Northeast Pacific Gastropod book project. The manuscript in outline form was significantly modified and few of McLean’s taxonomic indications in the manuscript were accepted. Dimensions given are for maximum size in any axis. Abundance indications have been omitted because the number of samples from bathyal and abyssal depths is very small, which precludes any meaningful assessment of their true abundance.
