Vermeij; e-mail: [email protected] Downloaded from (Received 5 September 2013; accepted 10 February 2014) ABSTRACT The shells of many marine gastropods have ventrally directed serrations (serial projections) at the edge http://mollus.oxfordjournals.org/ of the adult outer lip. These poorly studied projections arise as extensions either of external spiral cords or of interspaces between cords. This paper describes taxonomic, phylogenetic, architectural and func- tional aspects of serrations. Cord-associated serrations occur in cerithiids, strombids, the personid Distorsio anus, ocenebrine muricids and some cancellariids. Interspace-associated serrations are phylo- genetically much more widespread, and occur in at least 16 family-level groups. The nature of serration may be taxonomically informative in some fissurellids, littorinids, strombids and costellariids, among other groups. Serrated outer lips occur only in gastropods in which the apex points more backward than upward, but the presence of serrations is not a necessary byproduct of the formation of spiral sculp- tural elements. -

Biography James Hamilton McLean was born in Detroit, Michigan, on June 17, 1936. The McLean family moved to Dobbs Ferry, New York, on the Hudson River in 1940, a short train ride and subway ride away from the American Museum of Natural History (AMNH). His brother Hugh recalled that, “AMNH became the place of choice to go to whenever we could get someone to take us. Those visits opened our eyes to the variety and possibilities of what was out there, waiting for us to discover and collect.” From an early age James seemed destined to have a career at a museum (Figs 1–2). -

Prosobranch Gastropods of Guam
Micronesica 35-36:244-270. 2003 Prosobranch gastropods of Guam BARRY D. SMITH Marine Laboratory University of Guam Mangilao, Guam 96923 U.S.A. email: [email protected] Abstract—Based on records from invertebrate collections at the University of Guam, specimens cataloged at other institutions, and the published literature, there are 895 species of prosobranch gastropods from Guam. The vast majority of the species are marine, but terrestrial and aquatic prosobranchs are included. Most the species recorded to date are conspicuous, epibenthic species from shallow reef habitats, but some species have been taken from depths up to 400 m. Microgastropods less than 7 mm in size have been poorly investigated to date. Comparison of prosobranch gastropods from Guam and Enewetak reveal that some 56% of the species occurring at Enewetak are found in Guam. Introduction Molluscs have been collected in Guam since the arrival of the earliest inhabitants (Thompson, 1945). Despite the long history of European contact with the island, scant attention was given to systematic investigation of the fauna until the collections of Quoy and Gaimard (1824–1826; 1830–1834). Hidalgo (1904– 1905) was the first to produce a catalog that included molluscs from Guam, but his emphasis was mostly on the Philippine Islands fauna. This catalog was followed by a series of unpublished lists produced by shell collectors and shell club members during the last several decades. Synoptic collections of molluscs from Guam and Micronesia were started by faculty of the University of Guam in the mid-1960s. These collections are housed in the Richard E. Dickinson Memorial Mollusc Collection at the University of Guam Marine Laboratory. -

A Phylogeny of Vetigastropoda and Other Archaeogastropods
Invertebrate Biology 129(3): 220–240. r 2010, The Authors Journal compilation r 2010, The American Microscopical Society, Inc. DOI: 10.1111/j.1744-7410.2010.00198.x A phylogeny of Vetigastropoda and other ‘‘archaeogastropods’’: re-organizing old gastropod clades Stephanie W. Aktipisa and Gonzalo Giribet Department of Organismic and Evolutionary Biology and Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 02138, USA Abstract. The phylogenetic relationships among the ‘‘archaeogastropod’’ clades Patellogastro- poda, Vetigastropoda, Neritimorpha, and Neomphalina are uncertain; the phylogenetic place- ment of these clades varies across different analyses, and particularly among those using morphological characteristics and those relying on molecular data. This study explores the re- lationships among these groups using a combined analysis with seven molecular loci (18S rRNA, 28S rRNA, histone H3, 16S rRNA, cytochrome c oxidase subunit I [COI], myosin heavy-chain type II, and elongation factor-1a [EF-1a]) sequenced for 31 ingroup taxa and eight outgroup taxa. The deep evolutionary splits among these groups have made resolution of stable relationships difficult, and so EF-1a and myosin are used in an attempt to re-examine these ancient radiation events. Three phylogenetic analyses were performed utilizing all seven genes: a single-step direct optimization analysis using parsimony, and two-step approaches using par- simony and maximum likelihood. A single-step direct optimization parsimony analysis was also performed using only five molecular loci (18S rRNA, 28S rRNA, histone H3, 16S rRNA, and COI) in order to determine the utility of EF-1a and myosin in resolving deep relationships. In the likelihood and POY optimal phylogenetic analyses, Gastropoda, Caenogastropoda, Neritimorpha, Neomphalina, and Patellogastropoda were monophyletic. -

Fossil and Recent molluscan types in the Auckland War Memorial Museum. Part 3: Gastropoda (Patellogastropoda and Vetigastropoda) Wilma M. Blom Auckland War Memorial Museum Abstract The Marine Department of Auckland War Memorial Museum has an actively growing type collection with over 1770 primary types and a further 1836 paratypes and paralectotypes. The majority are molluscan, and this third part of a catalogue of these collections reviews the types for 12 Patellogastropoda and 184 Vetigastropoda species and subspecies. It deals with 130 primary types and 142 secondary type lots, which are split between 140 Recent taxa and 56 fossil taxa. Eleven of the holotypes reviewed here are illustrated for the first time.
