Constructional Morphology of Cerithiform Gastropods
Paleontological Research, vol. 10, no. 3, pp. 233–259, September 30, 2006 6 by the Palaeontological Society of Japan Constructional morphology of cerithiform gastropods JENNY SA¨ LGEBACK1 AND ENRICO SAVAZZI2 1Department of Earth Sciences, Uppsala University, Norbyva¨gen 22, 75236 Uppsala, Sweden 2Department of Palaeozoology, Swedish Museum of Natural History, Box 50007, 10405 Stockholm, Sweden. Present address: The Kyoto University Museum, Yoshida Honmachi, Sakyo-ku, Kyoto 606-8501, Japan (email: [email protected]) Received December 19, 2005; Revised manuscript accepted May 26, 2006 Abstract. Cerithiform gastropods possess high-spired shells with small apertures, anterior canals or si- nuses, and usually one or more spiral rows of tubercles, spines or nodes. This shell morphology occurs mostly within the superfamily Cerithioidea. Several morphologic characters of cerithiform shells are adap- tive within five broad functional areas: (1) defence from shell-peeling predators (external sculpture, pre- adult internal barriers, preadult varices, adult aperture) (2) burrowing and infaunal life (burrowing sculp- tures, bent and elongated inhalant adult siphon, plough-like adult outer lip, flattened dorsal region of last whorl), (3) clamping of the aperture onto a solid substrate (broad tangential adult aperture), (4) stabilisa- tion of the shell when epifaunal (broad adult outer lip and at least three types of swellings located on the left ventrolateral side of the last whorl in the adult stage), and (5) righting after accidental overturning (pro- jecting dorsal tubercles or varix on the last or penultimate whorl, in one instance accompanied by hollow ventral tubercles that are removed by abrasion against the substrate in the adult stage). Most of these char- acters are made feasible by determinate growth and a countdown ontogenetic programme. -

^;^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. -

SURVEY of the LITERATURE on RECENT SHELLS from the RED SEA (Second Enlarged and Revised Edition)
TRITON 24 SEPTEMBER 2011 SUPPLEMENT 1 SURVEY OF THE LITERATURE ON RECENT SHELLS FROM THE RED SEA (second enlarged and revised edition) L.J. van Gemert *) Abstract: About 2,100 references are listed in the survey. Shells are being considered here as shell-bearing mollusks of the Gastropoda, Bivalvia and Scaphopoda. And the region covered is not only the Red Sea, but also the Gulf of Aden, including Somalia, and the Suez Canal, including Lessepsian species. Literature on fossils finds, especially from the Pliocene, Pleistocene and Holocene, is listed too. Introduction My interest in recent shells from the Red Sea dates from about 1996. Since then, I have been, now and then, trying to obtain information on this subject. Recently I decide to stop gathering information in a haphazard way and to do it more properly. This resulted in a survey of approximately 1,420 references (Van Gemert, 2010). Since then, this survey has been enlarged considerably and contains now approximately 2,100 references. They are presented here. Scope In principle every publication in which mollusks are reported to live or have lived in the Red Sea should be listed in the survey. This means that besides primary literature, i.e. articles in which researchers are reporting their finds for the first time, secondary and tertiary literature, i.e. reviews, monographs, books, etc are to be included too. These publications were written not only by a wide range of authors ranging from amateur shell collectors to profesional malacologists but also by people interested in other fields. This implies that not only malacological journals and books should be considered, but also publications from other fields or disciplines, such as environmental pollution, toxicology, parasitology, aquaculture, fisheries, biochemistry, biogeography, geology, sedimentology, ecology, archaeology, Egyptology and palaeontology, in which Red Sea shells are mentioned. -

Marine Gastropods of American Samoa Introduction
Micronesica 41(2):237–252, 2011 Marine gastropods of American Samoa D.P. Brown Isle Royale National Park, Houghton, MI 49931 Abstract—Collected for food for over 3,000 years by the indigenous Samoan people, marine gastropods in American Samoa have never been collected and cataloged for science. This study documents 385 marine gastropods from 50 families occurring in the U.S. territory of American Samoa. Ten of these are listed by genus only and one by family. The num- ber of gastropods currently reported is likely significantly underestimated and a conservative estimate of the richness yet to be discovered. Introduction Molluscs have been collected in Samoa since the earliest inhabitants arrived some 3,000 years ago (Craig et al 2008, Kramer 1994, Kirch and Hunt, 1993, Nagaoka 1993). Much of this reef gleaning was directed at the cephalopods, the large and colorful giant clams (Tridacna spp.) and the larger marine snails such as Trochus spp, Lambis spp., Cassis spp., Turbo spp., and Tutufa spp., although any marine mollusc was likely taken if found (Munro 1999). While the limited archeological evidence provides an initial species list, this long history of the use of marine molluscs provided a very limited understanding of the marine gastro- SRGVRIWKHDUFKLSHODJR(YHQDIWHU(XURSHDQFRQWDFWIHZVHULRXVRUDPDWHXUVKHOO collectors made the long voyage to the S. Pacific to catalog the gastropoda. Until very recently, and before the advent of SCUBA, much of the gastropod knowledge in the area came from the shallow depths available to free-divers, what could be dredged off the bottom, and what washed onto the shore. The first organized sci- entific investigations into the Samoan gastropods weren’t carried out until the 18th century by the La Perouse expedition. -
Mollusca of New Caledonia
Plate 12 Mollusca of New Caledonia Philippe BOUCHET, Virginie HEROS, Philippe MAESTRATI, Pierre LOZOUET, Rudo von COSEL, Delphine BRABANT Museum National d'Histoire Naturelle, Paris malaco@mnhnJr The first record of a land mollusc (Placostylus fibratus (Martyn, 1784» from New Caledonia can unequivocally be traced to the voyage of Cook that discovered the island in 1774. By contrast, the marine molluscs of New Caledonia ironically remained out of reach to European natural history cab inets until well into the 19th century. New Caledonia remained untouched by the circumnavigating expeditions of the 1830-1840s onboard, e.g., the "Astrolabe", the "Zelee" or the "Uranie". Seashells may have been collected in New Caledonia by whalers and other merchants in search of sandalwood or beche-de-mer, and then traded, but by the time they reached European conchologists, all indica tion of their geographical origin had faded away. It is impossible to tell whether Indo-West Pacific species originally described from localities such as "Mers du Sud" or "Southern Seas" were original ly collected in, e.g., Fiji, Tahiti, Australia or New Caledonia. However, even ifNew Caledonian shells may have arrived on the European market or in cabinets, it must have been in very small amount, as such an emblematic species of the New Caledonia molluscan fauna as Nautilus macromphalus was not named until 1859. In fact, it was not until Xavier Montrouzier set foot in New Caledonia that the island was placed on the map of marine conchology. From there on, three major periods can be rec ognized in the history of New Caledonia marine malacology. -

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. -

ZooKeys 758: 1–18.https://doi.org/10.3897/zookeys.758.25100 Abstract A new genus, Limatium gen. n., and two new species, L. pagodula sp. n. and L. aureum sp. n. are described, found on outer slopes of barrier reefs and fringing reefs in the South Pacific. They are rare for cerithiids, which typically occur in large populations. The two new species are represented by 108 specimens sampled over a period of 30 years, only 16 of which were collected alive. Three subadults from the Philippines and Vanuatu likely represent a third species. In addition to their rarity, Limatium species are atypical for cerithiids in their smooth, polished, honey to golden brown shells with distinctive white fascioles extending suture to suture. -
Revision of Higher Taxa in Genus Cerithidea (Mesogastropoda: Potamididae) Based on Comparative Morphology and Biological Data
REVISION OF HIGHER TAXA IN GENUS CERITHIDEA (MESOGASTROPODA: POTAMIDIDAE) BASED ON COMPARATIVE MORPHOLOGY AND BIOLOGICAL DATA RICHARD S. HOUBRICK CURATOR OF MOLLUSKS, DEPARTMENT OF INVERTEBRATE ZOOLOGY, NATIONAL MUSEUM OF NATURAL HISTORY, SMITHSONIAN INSTITUTION, WASHINGTON, D.C. 20560, U.S.A. ABSTRACT A cladistic analysis of Cehthidea subgenera based on morphological studies of Cehthidea species is presented. Tfie morphology of Cerilhidea (Cerithideopsis) scalariformis Say, 1825 is described and compared with observations and published accounts of other species in the genus. An account of the reproduction, spawn, development and growth of this species along with ecological observations are presented and compared with other Cerithidea taxa in order to summarize what is known of the biology of the genus, to develop a holistic, less arbitrary classification, and to formulate systematic definitions of the subgenera comprising it. A detailed description of the siphonal eye is given and a survey made of similar structures in other cerithiacean groups. The genus Cerilhidea, sensu lato, is an estuarine group characterized by turreted shells with dominant axial sculpture, wide apertures, thick outer lips, and short anterior canals. The taenioglossate radula is short and all teeth bear cusps. The operculum is thin, corneous, multispiral and has a central nucleus. The ctenidium is either reduced or of broad low filaments. A simple ridge-like osphradium is present. The alimentary tract includes a pair of anterior salivary glands, a mid-esophageal crop, and a long style sac. Females have an ovipositor, a spermato- phore bursa in the outer lamina and a seminal receptacle in the inner lamina of the proximal palliai oviduct.
