CERNOHORSKY (Auckland Institute and Museum, Auckland, New Zealand) Text-figs. 1-19) (fimp of a revision The examination of type-specirnens Nassariidae in preparation for of Indo-Pacific Nassariidae, has brought to light new information which has a bearing on the established taxonorny of Nassariidae, in the way of chronelogical priority and alterations in synonymy. In case of Japanese Nassariidae, a DuNKER species is introduced into Japanese literature, while the synonyrny of other species is elucidated.

As far as the colouring is concerned, individuals vary from white, cream to brown, and sometimes are banded either with brown or white, depending which base colour predominates. Although specimens have been recorded as deep as 116 meters, in the Fiji Islands specimens were found in numbers by hand-dredging in shallow water. Specirriens taken in an area of only 10 square meters, matched practically every variant of N.

It is a worn, immature, creamy-yellow specimen with 17 axial ribs on each of the last 2 whorls, 4-5 spiral threads on the penultirnate whorl and 11 on the body whorl, the columella has 8 plicae and the outer lip 9 denticles. Nassa microstoma PEAsE, 1860 : The holotype is in the British Museum (Nat. Hist.), London, No. 1961458, dimensions length 9.0mm, width 4.0mm. It is a slender, juvenile individual which is white with a single brown band on each and whorl, 15 axial ribs on each of the last 2 whorls and the columellar plicae denticles on the outer lip have not as yet developed. Nassa dermestina GouLD, 1860: The holotype is in the National Museum of Natural History, Washington, No. USNM 24166, dimensions length 7. 0mm, width 3,4mm. The specimen is slender, creamy-yellow in colour, and has 16 axial ribs on each of the last 2 wherls. Being an adult, the columella is calloused and plicae and denticles are present. Nassa Plebecula GouLD, 1860: The lectotype is in the National Museum of No. 24168, width Natural History,Washington, USNM dimensions length 10.3mm, each of 4,8mm. The specimen is light yellowish-brown and has 17 axial ribs on the last 2 whorls and is fully mature with a calloused, plicate columella and denticulate outer lip. NassaProducta SOwERBy, 1897: The holotype is in the British Museum (Nat, Hist.), London, No 1899.4.14.3604, dimensions length 13.7mm, width 5.7 mm.

Being adult, the columella is calloused and plicate and the outer lip - denticulate. From examination of numerous Indo-Pacific specimens and comparison with the types, it is concluded that Nassarius (Hima) Pauperus (GouLD, 1850), is the earliest applicable name for the species.

But yet our knowledge about this subject seems to be far from complete. Thus the present work is planned to enrich the knowledge in this field and based mainly on Japanese species as many as possible. In my previous paper (ARAKAWA '62), I have already given a general account on the molluscan faeces at the present level of our knowledge in this field to­ gether with my unpublished data, and so in the first part of this serial work, I am going to describe and illustrate in detail the morphological characters of faecal pellets of molluscs collected in the Inland Sea of Seto and its neighbour­ ing areas. Before going further, I must express here my hearty thanks first to the late Dr. IsAo TAKI who educated me to carry out works in Malacology as one of his pupils, and then to Drs.

  • Complete Mitochondrial Genomes of Two Toxin-Accumulated Nassariids (Neogastropoda: Nassariidae: Nassarius) and Their Implication for Phylogeny

However, the previous shell or radula-based classification of Nassarius is quite confusing due to the homoplasy of certain morphological characteristics. The toxin accumulators Nassarius glans and Nassarius siquijorensis are widely distributed in the subtidal regions of the Indo-Pacific Ocean. In spite of their biological significance, the phylogenetic positions of N. glans and N. siquijorensis are still undetermined. In the present study, the complete mitochondrial genomes of N. glans and N. siquijorensis were sequenced. The present mitochondrial genomes were 15,296 and 15,337 bp in length, respectively, showing negative AT skews and positive GC skews as well as a bias of AT rich on the heavy strand. They contained 13 protein coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and several noncoding regions, and their gene order was identical to most caenogastropods.

  • Molluscs of the Northern Mariana Islands, with Special Reference to the Selectivity of Oceanic Dispersal Barriers1
    Molluscs of the Northern Mariana Islands, With Special Reference to the Selectivity of Oceanic Dispersal Barriers1 GEERAT J. VERMEIJ Department of Zoology, University of Maryland, College Park, Maryland 20742 E. ALISON KAY Department of Zoology, University of Hawaii, Honolulu, Hawaii 96822 LUCIUS G. ELDREDGE University of Guam Marine Laboratory, UOG Station, Mangilao, Guam 96913 Abstract- The shelled molluscan fauna of the Northern Marianas, a chain of volcanic islands in the tropical western Pacific, consists of at least 300 species. Of these, 18 are unknown from or are very rare in the biologically better known southern Marianas. These northern-restricted species are over-represented among limpets and in the middle to high intertidal zones of the northern Marianas. At least 22 gastropods which are common in the intertidal zone and on reef flats of the southern Marianas are absent in the northern Marianas. The northern Marianas lie within the presumed source area of the planktonically derived part of the Hawaiian marine fauna. The ocean barrier between the northern Marianas and the Hawaiian chain appears to select against archaeogastropods and against intertidal species but is unselective with respect to adult size and to other aspects of gastropod shell architecture. These findings are consistent with those for other dispersal barriers. Introduction The Mariana Islands form the southern part of an island chain which extends northward through the Bonin, Volcano, and lzu Islands to central Honshu, Japan. Whereas the marine biota of the southern Marianas (Guam, Rota, Tinian, and Saipan) is becoming relatively well known, that of the northern Marianas (Fig. 1) is largely unstudied.

  • Mollusca of New Caledonia
    Plate 12 Mollusca of New Caledonia Philippe BOUCHET, Virginie HEROS, Philippe MAESTRATI, Pierre LOZOUET, Rudo von COSEL, Delphine BRABANT Museum National d'Histoire Naturelle, Paris malaco@mnhnJr The first record of a land mollusc (Placostylus fibratus (Martyn, 1784» from New Caledonia can unequivocally be traced to the voyage of Cook that discovered the island in 1774. By contrast, the marine molluscs of New Caledonia ironically remained out of reach to European natural history cab­ inets until well into the 19th century. New Caledonia remained untouched by the circumnavigating expeditions of the 1830-1840s onboard, e.g., the "Astrolabe", the "Zelee" or the "Uranie". Seashells may have been collected in New Caledonia by whalers and other merchants in search of sandalwood or beche-de-mer, and then traded, but by the time they reached European conchologists, all indica­ tion of their geographical origin had faded away. It is impossible to tell whether Indo-West Pacific species originally described from localities such as "Mers du Sud" or "Southern Seas" were original­ ly collected in, e.g., Fiji, Tahiti, Australia or New Caledonia. However, even ifNew Caledonian shells may have arrived on the European market or in cabinets, it must have been in very small amount, as such an emblematic species of the New Caledonia molluscan fauna as Nautilus macromphalus was not named until 1859. In fact, it was not until Xavier Montrouzier set foot in New Caledonia that the island was placed on the map of marine conchology. From there on, three major periods can be rec­ ognized in the history of New Caledonia marine malacology.

Vermeij Department of Earth and Planetary Sciences, University of California, One Shields Avenue, Davis, CA 95616, USA Correspondence: G.J. Vermeij; e-mail: [email protected] (Received 22 July 2016; editorial decision 29 November 2016) ABSTRACT The relationship between shell form and mode of life in gastropods is important to the interpretation of fossils, but has been little explored owing, in part, to the great diversity of gastropod shells. Infaunal gas- tropods that actively bury in sand must conform to the demands of moving efficiently and noiselessly through a dense granular medium, but which shell characters reflect these demands and how infaunal gastropods differ from surface-dwelling (epifaunal) species remain incompletely answered questions. Here, I survey infaunal and epifaunal Indo-West Pacific members of four families (Cerithiidae, Mitridae, Costellariidae and Conidae) and consider more broadly the distribution of shell traits that confer stream- lining and other potential benefits to infaunal species. Sand-burying cerithiids, mitrids and costellariids (but not conids) have on average slenderer shells than their epifaunal counterparts.

  • Checklist of the Mollusca of Cocos (Keeling) / Christmas Island Ecoregion
    RAFFLES BULLETIN OF ZOOLOGY 2014 RAFFLES BULLETIN OF ZOOLOGY Supplement No. 30: 313–375 Date of publication: 25 December 2014 http://zoobank.org/urn:lsid:zoobank.org:pub:52341BDF-BF85-42A3-B1E9-44DADC011634 Checklist of the Mollusca of Cocos (Keeling) / Christmas Island ecoregion Siong Kiat Tan* & Martyn E. Y. Low Abstract. An annotated checklist of the Mollusca from the Australian Indian Ocean Territories (IOT) of Christmas Island (Indian Ocean) and the Cocos (Keeling) Islands is presented. The checklist combines data from all previous studies and new material collected during the recent Christmas Island Expeditions organised by the Lee Kong Chian Natural History Museum (formerly the Raffles Museum of Biodiversty Resarch), Singapore. The checklist provides an overview of the diversity of the malacofauna occurring in the Cocos (Keeling) / Christmas Island ecoregion. A total of 1,178 species representing 165 families are documented, with 760 (in 130 families) and 757 (in 126 families) species recorded from Christmas Island and the Cocos (Keeling) Islands, respectively. Forty-five species (or 3.8%) of these species are endemic to the Australian IOT. Fifty-seven molluscan records for this ecoregion are herein published for the first time. We also briefly discuss historical patterns of discovery and endemism in the malacofauna of the Australian IOT. Key words. Mollusca, Polyplacophora, Bivalvia, Gastropoda, Christmas Island, Cocos (Keeling) Islands, Indian Ocean INTRODUCTION The Cocos (Keeling) Islands, which comprise North Keeling Island (a single island atoll) and the South Keeling Christmas Island (Indian Ocean) (hereafter CI) and the Cocos Islands (an atoll consisting of more than 20 islets including (Keeling) Islands (hereafter CK) comprise the Australian Horsburgh Island, West Island, Direction Island, Home Indian Ocean Territories (IOT).

  • Molluscan Distribution Patterns in Fanning Island Lagoon and a Comparison of the Mollusks of the Lagoon and the Seaward Reefsi
    Pacific Science (1974), Vol. 28, No.3, p. 275-295 Printed in Great Britain Molluscan Distribution Patterns in Fanning Island Lagoon and a Comparison of the Mollusks of the Lagoon and the Seaward ReefsI E. ALISON KAy2 AND MARILYN F. SWITZER3 ABSTRACT: Lagoon molluscan assemblages at Fanning Island are described in terms of three topographical areas: the lagoon reef flat, the patch reefs, and the lagoon floor. Among the large mollusks, CtJIpeomorus brevis, Rhinoclavis asper, Pupa su/cata, Pyramidel/a sp., and two bivalves, Fragum fragum and Tel/ina robusta, are the principal components of the fauna of the reef flat; Cypraea moneta and Trochus histrio are the dominant epifaunal mollusks of rubble on patch reefs; and sessile bivalves, Carditavariegata, E/ectroma sp., Ostrea sandvichensis, and Tridacna maxima, are associated with coral. The micromolluscan assemblages of the lagoon reef flat are dominated by Trico/ia variabi/is, and patch reef and lagoon floor assemblages by Dia/a ftammea. Obtortio sulci/era is the second most abundant mollusk on the patch reefs and O. pupoides the second most abundant mollusk on the lagoon floor. The patch reef and lagoon floor assemblages are distinguishable into assemblages associated with turbid water and clear water areas of the lagoon. Standing crops of micromollusks are greatest on the windward or southeastern periphery of the lagoon reef flat. The lagoon mollusks are distinguished from the seaward reef mollusks in terms of species composition, modes of life, and feeding habits. The lagoon assemblages are predominantly herbivores and suspension feeders among the macrofauna, and are epifaunal herbivores among the microfauna.
