S. DE SOUZA Museu de Zoologia / USP, CP 42596, 04299-970, São Paulo, SP, Brazil ([email protected]) Abstract A new bathyal species of Fasciolaria is described for the southwestern Caribbean based on concho- logical characters. Fasciolaria tephrina sp. nov. is distinguishable from its west Atlantic congeners by its ashen white color, highly convex whorls, long thin siphonal canal, and large deviated proto- conch. Key words: Gastropoda, Fasciolariidae, Fasciolaria, bathyal, taxonomy Introduction The genus Fasciolaria comprises large, spindle shaped, carnivorous gastropods living in tropical and temperate oceans of the world. According to Rosenberg (2002: Malacolog 3.1.2 online database) in the tropical western Atlantic, there are currently five taxa: F. tulipa (Linné, 1758); F. lilium lilium Fischer, 1807; F. lilium hunteria (Perry, 1811); F. hol- listeri Weisbord, 1962; F. bullisi Lyons, 1972. However, their species level taxonomy (i.e. validity and or taxonomic rank) is still controversial, since the status of these taxa is not well established (see the specific classification adopted by, e.g., Abbott, 1974; Miloslav- ich, 1996 and Pechaszadeh & Paredes, 1996), and there is overlap in the geographical range of some putative subspecies (Rosenberg, 2002; Abbott, 1974), which is not in accord with the concept of subspecies. Moreover, a thorough revision of the group, which is beyond the scope of the present study, is still lacking. The other western Atlantic species is the Magellanic Fasciolaria insularis Fernández, 1977 from Isla de los Estados, Argentina, is quite distinctive from its congeners due to shell size and the short siphonal canal. Its radula (Fernández, 1977: 28, fig 3), however, conforms to the Fasciolariidae norm (e.g. Bandel, 1984: pl. 17 figs. 5 –10). Accepted: 27 June 2002; published: 5 July 2002 1.

The want of a complete and consistent list of the principal subdivisions of the mollusks having been experienced for some time, and such a list being at length imperatively needed for the arrangement of the collections of the Smithsonian Institution, the present arrangement has been compiled for that purpose. It must be considered simply as a provisional list, embracing the results of the most recent and approved researches into the systematic relations and anatomy of those animals, but from which innova- tions and peculiar views, affecting materially the classification, have been excluded.

Insgesamt können 24 Arten nachgewiesen werden. Tonnoidea weisen generell eine ungewöhnliche weite geographische und stratigraphische Verbreitung auf, wie sie bei anderen Gastropoden unbekannt ist. Dementsprechend sind die paratethyalen Arten meist auch in der mediterranen und der atlantischen Bioprovinz vertreten. Einige Arten treten zuerst im mittleren Miozän der Paratethys auf. Insgesamt dokumentiert die Verteilung der tonnoiden Gastropoden in der Parate- thys einen starken klimatischen Einfluss.

Reproductive Biology of the Tropical-Subtropical Seagrasses of the Southeastern United States
Reproductive Biology of the Tropical-Subtropical Seagrasses of the Southeastern United States Mark D. Moffler and Michael J. Durako Florida Department of Natural Resources Bureau of Marine Research 100 Eighth Ave., S.E. St. Petersburg, Florida 33701 ABSTRACT Studiesof reproductivebiology in seagrassesof the southeasternUnited States have addressed descriptive morphologyand anatomy,reproductive physiology, seed occurrence,and germination.Halodale wrightii Aschers.,Halophila engelmannii Aschers., Syringodium filiforme Kutz., and Thalassiatestudiaum Banks ex Konig are dioecious;Halophila decipiens Ostenfeld and Ruppiamaritima L. are monoecious.In Halophila johrtsoaii Eiseman, only fernale flowers are known. With the exception of R, maritima, which has hydroanemophilouspollination, these species have hydrophilous pollination. Recent reproductive-ecology studiessuggest that reproductivepatterns are due to phenoplasticresponses and/or geneticadaptation to physico-chemicalenvironmental conditions. Laboratory and field investigationsindicate that reproductive periodicityis temperaturecontrolled, but proposedmechanisms are disputed.Water temperature appears to influencefloral developmentand maybe importantin determiningsubsequent flower densities and fruit/seed production.Flowering under continuouslight in vitro suggeststhat photoperiodplays a limitedrole in floral induction.Flower expression and anthesis,however, may be influencedby photoperiod.Floral morpho- ontogeneticstudies of T. testudinumfield populationsdemonstrated the presenceof early-stageinflorescences

1 Northwest Florida Species List
NORTHWEST FLORIDA SPECIES LIST This list, which contains shells found in the onshore and offshore waters of the Florida Panhandle, was prepared by the members of the Gulf Coast Shell Club. The list is arranged alphabetically by family. The numbers to the left of the shell name refer to the corresponding species as found in American Seashells, Second Edition by Dr R. Tucker Abbott. An asterisk indicates that a name change to the family, species, genus, (or all) has occurred since publication. Shells annotated with a superscript 1 indicate form names that may or may not be valid but are useful for identification. Shells annotated with a superscript 2 are shells from the 1994 Keeler and Robertson survey of the Apalachicola Marine Estuary and immediate offshore areas and represent species not currently held by GCSC members but that are deemed native to our area. Common name for the shell and its normal adult size range columns are included. There are 635 shells (including forms) on this list as of the latest update in March, 2013. Our thanks go to Dr. Harry Lee of the Jacksonville Shell Club for his assistance in this compilation. A caution: Any list of this type is subject to frequent name changes as the science involved progresses.

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.

Notes on Buccinulum (Gastropoda, Buccinidae), a reappraisal. — Scripta Geol., 82: 83-100, pis 6-7, Leiden, January 1987 An attempt was made to assemble what is known at present of Buccinulum in the Indo-Western Pacific Region, fossil and Recent, more scope being offered by the discovery of new Miocene fossils from Java and Sumatra, and the recognition of further fossil species from India and Burma. This induced comparisons with, and revisions of some of the fossil and living species occurring in adjacent zoogeographical provinces. The Recent distribution of the subgenus Euthria appears to be much more extensive than when recorded by Wenz (1938-1944), the minimum enlargement encompassing an area stretching from the eastern Indian Ocean to Japan, via the Philippines and Ryukyu Islands. The knowledge of its fossil distribution, in the Indopacific Region long confined to Javanese Eocene, has likewise greatly expanded by discoveries made in Neogene to Quaternary of India, Burma, Indonesia (Sumatra, Java, Madura, and Borneo), the Philippines, New Hebrides, Fiji?, Ryukyu Islands, and Japan. The relevant data were tabulated. New taxa described are: Buccinulum pendopoense and B. sumatrense, both from presumed Preangerian of Sumatra, and B. walleri sedanense from the Rembangian of Java. It is proposed to include Ornopsis, which was described from the Upper Cretaceous of North America, as a subgenus of Buccinulum. It may well be ancestral to Euthria, considering its similarity to certain of the latter's fossil and living species.

Predation of Pelecypods and Gastropods by <I>Fasciolaria
FREDA TION OF PELECYPODS AND GASTROPODS BY FASG'IOLARIA HUNTERIA (PERRY) HARRY W. WELLS Department of Zoology, Duke University AND Institute of Fisheries Research, University of North Carolina ABSTRACT Laboratory and field predation of pelecypods and gastropods by Fas- cio/aria hunteria are described. Fascio/aria opens pelecypods by wedging its shell between the valves. Small gastropods are enveloped by the foot, while larger gastropods are eaten while the predator's foot holds out the operculum. A variety of pelecypods are eaten, oysters being the most attractive. Five gastropod species were eaten, including the oyster drill. Oyster drills are more attractive to Fascio/aria than are oysters, rates of daily predation of drills, in the presence of oysters, being as high as 5.7 drills/ Fascia/aria. Fascia/aria are found concentrated on oyster areas where drills or oysters probably form a major part of their diet. INTRODUCTION Ganaros (1957), reporting a fungus which invades the egg capsules of Urosalpinx dnerea, points out the remarkable scarcity of enemies of this troublesome oyster pest. Reviewing oyster drill literature, Carriker (1955) makes no mention of any enemy that might serve as a bio- logical check to this species. Although Flower (1954) noted that Polin ices dU[Jlicatus would eat drills when confined in an aquarium, its affinity for sandy bottoms effectively limits the chances for natural pre- dation of Urosalpinx. In many areas, Urosalpinx is recognized as the most important oyster enemy (Carriker, 1955). In the light of these facts, it seems desirable to report the feeding habits of Fasciolaria hunteria (Perry) (=F.

U.S. Virgin Islands Marine Resources and Fisheries Strategic and Comprehensive Conservation Plan 2005 UNITED STATES VIRGIN ISLANDS MARINE RESOURCES AND FISHERIES STRATEGIC AND COMPREHENSIVE CONSERVATION PLAN Division of Fish and Wildlife Department of Planning and Natural Resources U.S. Virgin Islands December 2005 U.S. Virgin Islands ii Marine Resources and Fisheries Strategic and Comprehensive Conservation Plan 2005 EXECUTIVE SUMMARY The US Virgin Islands (USVI) is a territory of the United States. It lies in the northeast Caribbean and consists of four major islands, St. Thomas, St. John, St. Croix, and Water Island, and about 50 cays. The USVI is endowed with many natural resources and contains examples of tropical ecosystems such as coral reefs, seagrass meadows, salt ponds, and mangrove forests. These habitats provide food and shelter for a large variety of resident marine and terrestrial life. In addition, a variety of fish and wildlife migrate through the USVI annually. These natural resources are under pressure from a variety of user groups. The marine waters are heavily fished by both recreational and commercial fishermen. Annually, thousands of tourists visit the USVI to go snorkeling and diving. Pollution is also a primary impact on the marine resources. In addition, economic development such as home and hotel construction continues to infringe on coastal environments. There have been numerous plans completed, at least to draft stage, relating to some aspect of the fisheries and marine resources in the U.S. Virgin Islands (Chapter 1). Plans have been written regarding management of specific areas, topics and issues, and species related to the fisheries and marine resources of the USVI.

ABSTRACT. Spawning and intracapsular development of the marine snail Hexaplex nigritus (Neograstropoda: Muricidae) in the laboratory. Introduction: The marine snail Hexaplex nigritus is a heav- ily exploited muricid in the Gulf of California for consumption and handcrafts. When they reproduce, adults aggregated in the form of artificial reefs facilitating their identification and extraction, situation that has reduced their population in that area. Objective: In order to investigate the spawning and intracapsular and larval devel- opment of this species as tools for its production in captivity for repopulation purposes. Methods: Eighteen brooders were collected and kept in a closed system with controlled parameters and feeding from April 2017 to September 2018. Growth of parents, spawning of ovigerous masses, number of capsules, and number of embryos and larvae within the capsules, were registered. The main morphological structures of embryos and larvae were documented according to their development.
