collection, a label of the former museum is retained for all registered specimens. The names of museum in the labels are “Rijksmuseum van Geologie en Mineralogie”, “Rijksmuseum van Geologie Leiden”, or “Rijks Geologisch-Mineralogisch Museum Leiden”. Labels in Japanese letters: The limited number of specimens are accompanied by Japanese labels. In most cases, labels are directly pasted on specimens. Names are written in Katakana letters only (e.g. Fig. 1E) or both in Chinese and Katakana letters (e.g. Figs. 1B, 3C, 3F). Identification of a few specimens in Japanese label is different from current our recognition and interesting. “Ryôkotsu” in Figs. 3F and 3H means dragon bones, but they are actually fragments of molluscan shells and eroded mammalian bones, respectively. In China, fossil vertebrate bones are called “Longgu” which is written in the same Chinese characters as “Ryôkotsu” in Japan, and have been used as a crude medicine. “Mimizu-ishi” in Fig. 2E stands for an earthworm stone, and winding tubes on the rock are bore holes of boring bivalve (“Teredo” sp.) with interior lining. Other fossils were precisely identified at phylum or class level. Examples are fossil fish (“Sekigyo”: Fig. 1B), fossil of wood (“Moku-kwaseki”: Fig. 4A), stone clam (“Ishi-hamaguri”: Fig. 11A), and fossil of heart urchin (“Kaien-no-kwaseki”: Fig. 3A). Molluscan specimens in Siebold fossil collection The molluscs in the Siebold fossil collection consist of more than 40 species as described below (Figs. 5-14). This number, however, does not contain the shell fragments in sandstone (Figs. 1D-G, 2A). In the following accounts, the depository of the specimens is in the mineralogical collection in Naturalis, unless otherwise mentioned. -
Feeding, Anatomy and Digestive Enzymes of False Limpet Siphonaria Guamensis

Murty, A. Shameem and K. Umadevi Department of Marine Living Resources Andhra University, Visakhapatnam 530 003, A.P., India Abstract: Very little information has been available in the literature on the feeding habits, anatomy and histology of digestive system of siphonariid limpets. The present study revealed Siphonaria guamensis feeds on the crustose red alga Hildenbrandia prototypus browsing on the rocks by rasping action of radula. The anatomy of digestive system of Siphonaria guamensis is similar with that of the other siphonariid limpets but the length of gut and colon are shorter than the patellogastropod limpets like Cellana radiata, patella vulgata, Fissurella barbadensis and species of Acmaea. The salivary glands are the main source of the enzyme system of Siphonaria guamensis. They contained enzymes which can act on carbohydrates, proteins and polysaccharides. The enzyme which can act on proteins was found only in salivary glands and not detected in any other part of the digestive system. No lypolytic activity was seen in any part of the digestive system of the animal.

Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998
Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998 Stephen A. Grabe Environmental Supervisor David J. Karlen Environmental Scientist II Christina M. Holden Environmental Scientist I Barbara Goetting Environmental Specialist I Thomas Dix Environmental Scientist II MARCH 2003 1 Environmental Protection Commission of Hillsborough County Richard Garrity, Ph.D. Executive Director Gerold Morrison, Ph.D. Director, Environmental Resources Management Division 2 INTRODUCTION The Environmental Protection Commission of Hillsborough County (EPCHC) has been collecting samples in Middle Tampa Bay 1993 as part of the bay-wide benthic monitoring program developed to (Tampa Bay National Estuary Program 1996). The original objectives of this program were to discern the ―health‖—or ―status‖-- of the bay’s sediments by developing a Benthic Index for Tampa Bay as well as evaluating sediment quality by means of Sediment Quality Assessment Guidelines (SQAGs). The Tampa Bay Estuary Program provided partial support for this monitoring. This report summarizes data collected during 1993-1998 from the Middle Tampa Bay segment of Tampa Bay. 3 METHODS Field Collection and Laboratory Procedures: A total of 127 stations (20 to 24 per year) were sampled during late summer/early fall ―Index Period‖ 1993-1998 (Appendix A). Sample locations were randomly selected from computer- generated coordinates. Benthic samples were collected using a Young grab sampler following the field protocols outlined in Courtney et al. (1993). Laboratory procedures followed the protocols set forth in Courtney et al. (1995). Data Analysis: Species richness, Shannon-Wiener diversity, and Evenness were calculated using PISCES Conservation Ltd.’s (2001) ―Species Diversity and Richness II‖ software. -

Lloyd1,*, Anna Metaxas1, Brad deYoung2 1Department of Oceanography, Dalhousie University, Halifax, Nova Scotia, Canada B3H 4R2 2Department of Physics and Physical Oceanography, Memorial University, St. John’s, Newfoundland, Canada A1B 3X7 ABSTRACT: Marine gastropods form a diverse taxonomic group, yet little is known about the factors that affect their larval distribution and abundance. We investigated the larval vertical dis- tribution and abundance of 9 meroplanktonic gastropod taxa (Margarites spp., Crepidula spp., Astyris lunata, Diaphana minuta, Littorinimorpha, Arrhoges occidentalis, Ilyanassa spp., Bittiolum alternatum and Nudibranchia), with similar morphology and swimming abilities, but different adult habitats and life-history strategies. We explored the role of physical (temperature, salinity, density, current velocities) and biological (fluorescence) factors, as well as periodic cycles (lunar phase, tidal state, diel period) in regulating larval vertical distribution. Using a pump, we collected plankton samples at 6 depths (3, 6, 9, 12, 18 and 24 m) at each tidal state, every 2 h over a 36 and a 26 h period, during a spring and neap tide, respectively, in St. George’s Bay, Nova Scotia. Con- currently, we measured temperature, salinity, density, fluorescence (as a proxy for chlorophyll, i.e. phytoplankton density), and current velocity. Larval abundance was most strongly related to tem- perature, except for Littorinimorpha and Crepidula spp., for which it was most strongly related to fluorescence. Margarites spp., A. -
Differential Algal Consumption by Three Species of <I>Fissurella</I
BULLETIN OF MARINE SCIENCE. 46(3): 735-748.1990 DIFFERENTIAL ALGAL CONSUMPTION BY THREE SPECIES OF FISSURELLA(MOLLUSCA:GASTROPODA)AT ISLA DE MARGARITA, VENEZUELA Craig J. Franz ABSTRACT Visual observations and gut analyses were used to determine types of food ingested by Fissurella nimbosa (Linnaeus, 1758), F. nodosa (Born, 1778), and F. barbadensis (Gmelin, 1791) at Isla de Margarita, Venezuela. Although these animals have a wide variety of algal sources from which to select and on which they appear to feed in an opportunistic fashion, specific food preferences exist. Fissurella nodosa prefers encrusting microalgae and diatoms; F. nimbosa ingests laminar sheets of predominantly brown algae; F. barbadensis feeds on a wide variety of algae but often selects coralline algae of which it ingests entire branches. In zones of overlap, it is hypothesized that competition for food among Fissurella species is minimal due to resource allocation through food preference. Laboratory experiments indicate that all three congeners can ingest a greater variety of algal types than they normally consume in the field. Differential food consumption indicates significantly more elaborate niche par- titioning among tropical intertidal Fissure/la than was previously known. Studies of comparative feeding among congeneric predators may provide insight into the manner by which organisms partition their environment. This partitioning may be achieved through spatial segregation, temporal allocation, or dietary pref- erence. In situations of spatial overlap and temporal feeding similarity, a unique opportunity exists to evaluate the way in which food preferences may help establish an individual's niche. In these circumstances, dietary studies of co-occurring congeners provides information concerning the partitioning of community food resources. -

ABSTRACT Title of Dissertation: PATTERNS IN
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. -
