However, little 15 is known about these planktonic veligers and identification of the larval state of many Cymatiidae 16 is challenging at best. Here we describe the first high-quality scanning electron microscopy images 17 of the developing veliger larvae of Monoplex pilearis and Monoplex parthenopeus (Gastropoda: 18 Cymatiidae). The developing shell of Monoplex veligers was captured by SEM, showing plates 19 secreted to form the completed shell. The incubation time of the two species was recorded and 20 found to be different; M. parthenopeus took 24 days to develop fully and hatch out of the egg 21 capsules, whereas M. pilearis took over a month to leave the egg capsule. Using scanning electron 22 microscopy and geometric morphometrics, the morphology of veliger larvae was compared. No 23 significant differences were found between the shapes of the developing shell between the two 24 species; however, it was found that M. pilearis was significantly larger than M.

An outline of cassoidean phylogeny (Mollusca, Gastropoda). — Contr. Tert. Quatern. Geo!., 32(4): 97-132, 43 figs. Leiden, December 1995. The phylogeny of cassoidean gastropods is reviewed, incorporating most of the biological and palaeontological data from the literature. Several characters have been checked personally and some new data are presented and included in the cladistic analysis. The Laubierinioidea, Calyptraeoidea and Capuloidea are used as outgroups. Twenty-three apomorphies are discussed and used to define cassoid relations at the subfamily level. A classification is presented in which only three families are recognised. The Ranellidae contains the subfamilies Bursinae, Cymatiinae and Ranellinae. The Pisanianurinae is removed from the Ranellidae and attributed to the Laubierinioidea.The Cassidae include the Cassinae, Oocorythinae, Phaliinae and Tonninae. The Ranellinae and Oocorythinae are and considered the of their families.

  • Gradual Miocene to Pleistocene Uplift of the Central American Isthmus: Evidence from Tropical American Tonnoidean Gastropods Alan G
    J. Paleont., 75(3), 2001, pp. 706±720 Copyright q 2001, The Paleontological Society 0022-3360/01/0075-706$03.00 GRADUAL MIOCENE TO PLEISTOCENE UPLIFT OF THE CENTRAL AMERICAN ISTHMUS: EVIDENCE FROM TROPICAL AMERICAN TONNOIDEAN GASTROPODS ALAN G. BEU Institute of Geological and Nuclear Sciences, P O Box 30368, Lower Hutt, New Zealand, ,[email protected]. ABSTRACTÐTonnoidean gastropods have planktotrophic larval lives of up to a year and are widely dispersed in ocean currents; the larvae maintain genetic exchange between adult populations. They therefore are expected to respond rapidly to new geographic barriers by either extinction or speciation. Fossil tonnoideans on the opposite coast of the Americas from their present-day range demonstrate that larval transport still was possible through Central America at the time of deposition of the fossils. Early Miocene occurrences of Cypraecassis tenuis (now eastern Paci®c) in the Caribbean probably indicate that constriction of the Central American seaway had commenced by Middle Miocene time. Pliocene larval transport through the seaway is demonstrated by Bursa rugosa (now eastern Paci®c) in Caribbean Miocene-latest Pliocene/Early Pleistocene rocks; Crossata ventricosa (eastern Paci®c) in late Pliocene rocks of Atlantic Panama; Distorsio clathrata (western Atlantic) in middle Pliocene rocks of Ecuador; Cymatium wiegmanni (eastern Paci®c) in middle Pliocene rocks of Atlantic Costa Rica; Sconsia sublaevigata (western Atlantic) in Pliocene rocks of Darien, Paci®c Panama; and Distorsio constricta (eastern Paci®c) in latest Pliocene-Early Pleistocene rocks of Atlantic Costa Rica. Continued Early or middle Pleistocene connections are demonstrated by Cymatium cingulatum (now Atlantic) in the Armuelles Formation of Paci®c Panama.

  • 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.

  • Evolution, Distribution, and Phylogenetic Clumping of a Repeated Gastropod Innovation
    Zoological Journal of the Linnean Society, 2017, 180, 732–754. With 5 figures. The varix: evolution, distribution, and phylogenetic clumping of a repeated gastropod innovation NICOLE B. WEBSTER1* and GEERAT J. VERMEIJ2 1Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9 2Department of Earth and Planetary Sciences, University of California, Davis, CA 95616, USA Received 27 June 2016; revised 4 October 2016; accepted for publication 25 October 2016 A recurrent theme in evolution is the repeated, independent origin of broadly adaptive, architecturally and function- ally similar traits and structures. One such is the varix, a shell-sculpture innovation in gastropods. This periodic shell thickening functions mainly to defend the animal against shell crushing and peeling predators. Varices can be highly elaborate, forming broad wings or spines, and are often aligned in synchronous patterns. Here we define the different types of varices, explore their function and morphological variation, document the recent and fossil distri- bution of varicate taxa, and discuss emergent patterns of evolution. We conservatively found 41 separate origins of varices, which were concentrated in the more derived gastropod clades and generally arose since the mid-Mesozoic. Varices are more prevalent among marine, warm, and shallow waters, where predation is intense, on high-spired shells and in clades with collabral ribs. Diversification rates were correlated in a few cases with the presence of varices, especially in the Muricidae and Tonnoidea, but more than half of the origins are represented by three or fewer genera. Varices arose many times in many forms, but generally in a phylogenetically clumped manner (more frequently in particular higher taxa), a pattern common to many adaptations.

  • Ranellidae and Personidae
    RANELLIDAE AND PERSONIDAE: A CLASSIFICATION OF RECENT SPECIES Betty Jean Piech Digitized by the Internet Archive in 2017 with funding from IMLS LG-70-15-0138-15 https://archive.org/details/ranellidaepersonOOunse - 3 - INTRODUCTION, NOTES AND ACKNOWLEDGMENTS In 1972, Dr. Rudolf Kilias authored an excellent monograph on the Family Cymatiidae. The following years have brought many changes; i.e., the family name is now Ranellidae, and distorsios are a separate family called Personidae. Therefore it was felt that a more up-to-date classification was needed as a guide for research and curatorial work. The classification herein presented is based on the examination of specimens in various museums and private collections, literature research, and exchange of information. No anatomical work was done. In the few cases where previously-used placement was changed, the entry is marked < *> indicating the decision was based on the author's unpublished research. New species were evaluated as they were published and added if they were considered to be valid. Those not accepted were placed in synonymy and also marked < *> . In a few cases where it was not possible to obtain specimens of newly-named species for examination and the available information did not seem adequate to make a definitive decision, the name was entered as a species and marked <**> indicating validity had not been verified. The format used is a listing of each subfamily, genus and subgenus, and species and subspecies, followed by synonyms in chronological order. Under each of these categories, the type is placed first followed in alphabetical order by the remainder of those that make up that specific group.

    Rev. Acad. Canar. Cienc, XIV (Nums. 3-4), 201-212 (2002) (publicado en agosto de 2003) DESCRIPTION OF A NEW SUBSPECIES OF CYMATIUM (GASTROPODA, RANELLIDAE) FROM THE ATLANTIC OCEAN. Francisco Garcia-Talavera* & Alejandro de Vera* (*) Museo de la Naturaleza y el Hombre, Santa Cruz de Tenerife, Canary Islands RESUMEN Se describe Cymatium (Monoplex) comptum amphiatlanticum n. ssp, para el Oceano Atlantico. Comparandola con especies similares de su grupo taxonomico como C. comptum (Adams, 1855), C. indomelanicum Garcia-Talavera, 1997 y C. vespaceum (Lamarck, 1822), se descubrieron caracteres morfologicos distintivos, pudiendo realizarse una diagnosis diffe- rencial. En principio, C. comptum amphiatlanticum parece ser similar a C. comptum, pero tras un estudio exhaustivo de la concha, se aprecian diferencias bien definidas. Todo ello sugiere que la forma atlantica de C. comptum puede ser considerada, al menos, una nueva subespecie. Pensamos que ambas tuvieron un ancestro comun procedente del Oceano Pacifico. Palabras Clave: Gastropoda, Ranellidae, Cymatium comptum amphiatlanticum, nueva subespecie, Oceano Atlantico. ABSTRACT Cymatium (Monoplex) comptum amphiatlanticum n. ssp. is described in the present work, from the Atlantic ocean. Comparing it with similar species of its taxonomic group as C. comptum (Adams, 1855), C. indomelanicum Garcia-Talavera, 1997 and C vespaceum (Lamarck, 1822), distinctive morphological characters of the protoconch and teleoconch were revealed. By doing this, a differential diagnosis was possible. In a first approach, C. comptum amphiatlanticum seems to be very close to C. comptum, but conspicuous differ- ences between them are visible after an exhaustive study of the shell. This suggest that the atlantic form of C. comptum can be considered, at least, a new subspecies.

  • SMITHSONIAN MISCELLANEOUS COLLECTIONS Sulcus
    "; AN HISTORICAL AND SYSTEMATIC REVIEW OF THE FROG-SHELLS AND TRITONS By WILLIAM HEALEY DALL Everyone who has looked upon the numerous " triumphs of Galatea," " births of Venus," and " processions of Neptune," in European picture galleries, scenes dwelt upon by mediaeval painters, has noticed the large, twisted, and variegated shells which are the invariable wind-instruments of the lusty Tritons who form the chorus " around the sea-born deities depicted. These shells, the " Buccina " of the ancients, became naturally in popular speech the Triton- " shells," and finally the " Tritons of the conchologist. Even at the present day on many an Italian hillside the sonorous note of these shells, blown by the peasants, serves to call the cattle home at dusk and they may even be heard occasionally on the alien farms of New England, in use for the same purpose, or as dinner horns. The elegant denticulation of the outer lip of these shells was copied in ages past by the silversmith, and the special conventional type of ornament thus derived has a name of its own, " gadrooning." Related to the Tritons is another group of shell-bearing mollusks, " variously known to eighteenth century conchologists as frogs (from their tubercular ornamentation) or "purses" (from their swollen oval form) and, since the development of a scientific nomen- clature, by the more attractive names of Ranella or Bursa. The history of the classification of these shells is very complex and has never been fully elucidated. The clearing up of some of the obscurity which has enveloped them and the proposal of a more modern and accurate system of classification for the two groups, is the object of this paper; in which the author has availed himself of the labors of many worthy predecessors, and, it is hoped, has made some advance on their conclusions.
