A Survey of the Littoral Gastropoda of the Netherlands Antilles And STUDIES ON THE FAUNA OF CURAÇAO AND OTHER CARIBBEAN ISLANDS: No. 31 A Survey of the Littoral Gastropoda of the Netherlands Antilles and other Caribbean Islands by H.E. Coomans (Zoologisch Museum, Amsterdam) This brief is based the material Dr. survey on collected by P. WagenaarHummelinck in 1936/37, 1948/49, and 1955. Station numbers only are cited; they refer to the “Description of new localities” in Volume IV of this series (1953; marine habitats p. 56-77) and to a “Third list oflocalities”which willbe published in a forthcoming volume. Other localities, which are not numbered, described in the are, as a rule, briefly text. Material assembled by a few other collectors has been added to Hummelinck’s collection. The names of the collectors are always mentioned, abbreviated as follows: Av.: R. Aveledo, Caracas Ga.: Wiesje and Hendrikje, Be.: J. G. van den Bergh, Aruba the two little daughters of BL. : T. Blok, Curaçao Mr. and Mrs. K. J. van Bo.: Mrs van den Bos, St Maarten Gaalen, Aruba. Co.: R. M. Collens, Tobago Za. : J. S. Zaneveld, Curaçao. For the sake of completeness the material discussed by TERA VAN BENTHEM in her "Marine Molluscs of the JUTTING paper on Island of Curasao" (1927) has been included (indicated by V.B.J.), few together with a other data on Netherlands Antilles Gastropoda from the literature of the subject, including those mentioned by J. J. SCHEPMAN in his contribution (1915) to the Encyclopaedie van Nederlandsch West-Indie (indicated by SCH.). 43 of his Dr. HUMMELINCK informed me that a considerable part marine material has not yet been examined for the presence of Gastropoda, and that the majority of the samples collected by Dr. ZANEVELD in Curasao, Aruba, and Bonaire (1954/55), and in the Aves Islands (1956), still await further study. which found in In this survey only Gastropoda are discussed were with the of shallow water or had been cast ashore, exception a few BLOK from water of about species which were trawled by skipper 20 fathoms north of Margarita. In point of fact all Caribbeanshallow- water Gastropoda are mentioned, with the exception of the Opistho- branchiata without an external shell. As regards the families, this study has been systematically based I on J. THIELE'S Handbuch der Systematischen Weichtierkunde, Vols. and II (1929) (1931); only a few exceptions have been made. The subgenera are not mentioned. Aftereach locality the numberofspecimens isrecorded in brackets, found alive. When this printed in italics if specimens were num- ber exceeds 25, the sign & (<§■) has been used. Young specimens are indicated by juv, shell fragments by fragm. — Many shells were occupied by hermit crabs, mostly Coenobita clypeata (abbreviated Coen.). A large number of these crabs were identified by Dr. J. H. HOLTHUIS, Leiden. and localities In the text attention is drawn to rare specimens, to situated outside the territory in which the species was hitherto known to occur. Thephotographs were taken by Dr. WAGENAAR HUMMELINCK, with Mr. the expert assistance of H. VAN KOOTEN, at the Zoological the Laboratory of State University, Utrecht, soon after the author had to leave for in order to continue his mala- cological studies. Dr. HUMMELINCK also compiled the accompanying the an enhance the valueof this other- table and map, in attempt to wise rather dry publication to all those interested in the sea-fauna of the Caribbean. 44 thanks due Mrs. W. S. FEEN Many are to S. VAN DER (formerly Miss TERA VAN BENTHEM for the in which she intro- JUTTING) way duced the present writer to malacology, and for her kind help in this the course of investigation. The material has been presented to the Zoological Museum of Amsterdam, with the of two small collections which in the exception are now Caribbean Marine Biological Institute, Cura9ao, and the Zoological Laboratory at Utrecht. The latter contains the Secretariat of the Foundation for Scientific Research in Surinam and the Netherlands Antilles, which has greatlyfacilitated this work. to Attention is drawn the following terms, which are often given different meanings but which here cover the areas as stated: West Indies eastern coast of Florida, Bahamas, Antilles, Central and South American coast from Yucatan as far as Orinoco River. (Bermudas excluded!) Florida Atlantic coast of Florida and Florida Keys. Antilles from Cuba to Trinidad and Aruba. Greater Antilles from Cuba to Puerto Rico. Lesser Antilles from Virgin Islands to Trinidad and Aruba. Gulf of Mexico western coast of Florida to Yucatan. Up to December 1956 the following numbers of species of Gastropoda Proso- branchia from the Netherlands Antilles had been examined by the author. To these must be added several species known from literature only (cited below between the will brackets). More thorough exploration of shores of the islands doubtless re- the sult in a quick and considerable increase in numbers of species studied.

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. Emerson of the American Museum of Natural History (six other siliquariid species in the collection of the Department of Living Invertebrates of the Ameri- 1 Department of Geology, Columbia University in the City of New York. 2 AMERICAN MUSEUM NOVITATES NO. 2263 can Museum of Natural History).

  • 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.

A few minute Belgrandiella-like gastropods were found in three springs in Georgia. Molecular markers: mitochondrial cytochrome oxidase subunit I (COI) and nuclear histone (H3) were used to infer their phylogenetic relationships. The phylogenetic trees placed them most closely to Agrafia from continental Greece. The p-distances indicated that two species occurred in the three localities. Two specimens from Andros Island (Greece) were also assigned to the genus Agrafia. The p-distances between the four taxa, most probably each representing a distinct species, were within the range of 0.026–0.043 for H3, and 0.089–0.118 for COI. KEY WORDS: spring snail, DNA, Georgia, Andros, phylogeny INTRODUCTION The freshwater gastropods of Georgia, as well as Graziana Radoman, 1975, Pontobelgrandiella Radoman, those of all the Caucasus, are still poorly studied; this 1973, and Alzoniella Giusti et Bodon, 1984.

Box 592, La Paz, 23096 Baja California Sur, México Corresponding author: Arturo Tripp-Quezada ([email protected]) RESUMEN. La distinción taxonómica es una medida de diversidad que presenta una serie de ventajas que dan connotación relevante a la ecología teórica y aplicada. La utilidad de este tipo de medida como otro método para evaluar la biodiversidad de los ecosistemas marinos bentónicos de fondos blandos del Golfo de Batabanó (Cuba) se comprobó mediante el uso de los índices de distinción taxonómica promedio (Delta+) y la variación en la distinción taxonómica (Lambda+) de las comunidades de moluscos. Para este propósito, se utilizaron los inventarios de especies de moluscos bentónicos de fondos blandos obtenidos en el periodo 1981-1985 y en los años 2004 y 2007. Ambos listados de especies fueron analizados y comparados a escala espacial y temporal. La composición taxonómica entre el periodo y años estudiados se conformó de 3 clases, 20 órdenes, 60 familias, 137 géneros y 182 especies, observándose, excepto en el nivel de clase, una disminución no significativa de esta composición en 2004 y 2007. A escala espacial se detectó una disminución significativa en la riqueza taxonómica en el 2004. No se detectaron diferencias significativas en Delta+ y Lambda+ a escala temporal, pero si a escala espacial, hecho que se puede atribuir al efecto combinado del incremento de las actividades antropogénicas en la región con los efectos inducidos por los huracanes.

  • Zooarchaeology of Cinnamon Bay, St. John, Us Virgin Islands
    Bull. Fla. Mus. Nat. Hist. (2003) 44(1): 131 -158 131 ZOOARCHAEOLOGY OF CINNAMON BAY, ST. JOHN, U.S. VIRGIN ISLANDS: PRE-COLUMBIAN OVEREXPLOITATION OF ANIMAL RESOURCES Irvy R. Quitmyeri The zooarchaeological remains from a stratigraphic sequence excavated from the ceremonial site of Cinnamon Bay, St. John, U.S. Virgin Islands, were studied. The samples were recovered using a fine-gauge (1/16 in) screen. During the course of this study, 443 minimum numbers of individuals and 99 species of vertebrates and invertebrates were identified. The fauna was analyzed by estimating the trophic level of reef, inshore, and pelagic zooarchaeological components from three strata representing the Monserrate (ca. A.D. 950), Santa Elena (ca. A.D. 570), and Chican (ca. A.D. 460) ceramic periods. The trophic level model shows an initial increase in the trophic level of taxa from the reef between the Monserrate and Santa Elena periods. This initial increase corresponds to the exponential growth of midden density. Relative to the earlier faunal assemblages, midden density and the mean trophic level of reef resources declines during the Chican period. Greater reliance on pelagic species from the deeper waters offshore and the increased use of mollusks from inshore habitats is also seen. The data show that at low levels of cultural complexity humans can alter their environments. This is particularly true of island biota where biological reservoirs are small. Key words: candy, Caribbean, island biogeography, trophic level, zooarchaeology This chapter presents a study of well-recovered Caribbean pre-Columbian people is not well zooarchaeological remains from the Cinnamon Bay site understood and should be considered in its formative (12Vam-2-3), St.
