Supplementary listings for bivalves and opisthobranch gastropods (pre- viously covered in Part 1) are also given. This catalog includes 1309 type lots, 18 lectotype designations, and illustrations for 12 previously inadequately illustrated type specimens and ®ve species never before illustrated. New synonymy information is given for nine species, one species is shown to be a valid name, one new replacement name is introduced, and one neotype is suppressed with rediscovery of type material. An appendix of AMNH specimens previously incorrectly cited as types is also given. An index of genera and species is included for each class and subclass.

The venue continues to be Function Room D and gavel time 7:00 PM. David Davies will present the shell-of-the-month, Donax variabilis Say, 1822, from Texas (R). Although he dealt with the topic earlier, he intends to wrap up some previously uncovereded aspects of this coquina’s biology. For many years the Texas populations were considered a subspecies, Donax v. roemeri Philippi, 1849, isolated from its parent taxon by the Mississippi estuary - Say’s subspecies being found in the eastern Gulf and from mid-Florida to VA on the Atlantic seaboard (including local beaches; (L). This position was supported with conchological evidence in an exhaustive monograph (Morrison, 1971). However, molecular geneticists, e.g. Adamkewicz & Harasewych (1994, 1996), found no evidence in support of this dichotomy. As I write this copy, I see that the World Registry of Marine Species (WoRMS: <http://www.marinespecies.org/aphia.php?p=taxdetails&id=156776>) follows the latter analysis. Maybe members can bring in specimens from both areas as we did with E/W Florida Pear Whelks a few months back, and we can see for ourselves if there is at least a consistent difference in the shells of these two coquinas.

  • 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.

  • THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
    August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject.

    Taxonomic study on the molluscs collected in Marion-Dufresne expedition (MD55) to SE Brazil: Xenophoridae, Cypraeoidea, mitriforms and Terebridae (Caenogastropoda) Luiz Ricardo L. SIMONE Carlo M. CUNHA Museu de Zoologia da Universidade de São Paulo, caixa postal 42494, 04218-970 São Paulo, SP (Brazil) [email protected] [email protected] Simone L. R. L. & Cunha C. M. 2012. — Taxonomic study on the molluscs collected in Marion-Dufresne expedition (MD55) to SE Brazil: Xenophoridae, Cypraeoidea, mitriforms and Terebridae (Caenogastropoda). Zoosystema 34 (4): 745-781. http://dx.doi.org/10.5252/z2012n4a6 ABSTRACT The deep-water molluscs collected during the expedition MD55 off SE Brazil have been gradually studied in some previous papers. The present one is focused on samples belonging to caenogastropod taxa Xenophoridae Troschel, 1852, Cypraeoidea Rafinesque, 1815, mitriforms and Terebridae Mörch, 1852. Regarding the Xenophoridae, Onustus aquitanus n. sp. is a new species, collected off the littoral of Espírito Santo and Rio de Janeiro, Brazil, 430-637 m depth (continental slope). The main characters of the species include the small size (c. 20 mm), the proportionally wide shell, the white colour, the short peripheral flange, the oblique riblets weakly developed and a brown multispiral protoconch. This appears to be the smallest living species of the family, resembling in this aspect fossil species. In respect to the Cypraeoidea, the following results were obtained: family Cypraeidae Rafinesque, 1815: Erosaria acicularis (Gmelin, 1791) and Luria cinerea (Gmelin, 1791) had the deepest record, respectively 607-620 m and 295-940 m, although the samples were all dead, eroded shells. Family Lamellariidae d’Orbigny, 1841: a total of three lots were collected, provisionally identified as Lamellaria spp.

    Phenotypic features of Helicina variabilis (Gastropoda: Neritimorpha) from Minas Gerais, Brazil Luiz Ricardo L. Simone¹ ¹ Universidade de São Paulo (USP), Museu de Zoologia (MZUSP). São Paulo, SP, Brasil. ORCID: 0000-0002-1397-9823. E-mail: [email protected] Abstract. Helicina variabilis Wagner, 1827 (Neritimorpha, Helicinidae) is redescribed based on a sample collected in Nanuque, northern Minas Gerais, Brazil. The species description, previously based only on the shell, is expanded to the phenotypic fea- tures. The study revealed absorption of the internal shell whorls; a diaphragm muscle connected to the floor of the pallial cav- ity; a monoaulic pallial oviduct, with the female genital aperture inside the anal aperture, and the lack of a seminal receptacle and provaginal sac; and the pleural ganglia of the nerve ring connected with each other.
