Twelve species in three genera (eight subgenera) were colleeted, of which five species are new reeords from Taiwan, and all of them are also distributed in Japan. There is a high zoogeographical aMnity between Taiwanese and Japanese neritid fauna. Matsuda (1924a, b), Herikawa (1935a, b), Kuroda (1941) and Pace (1973) have previously reperted on neritid fauna in Taiwan (Republic of China). Kureda listed 26 species in five genera, of which the freshwater or brackish water neritids are composed of one speeies in the genus Nerita, three in the genus Clithen, four in the genus Neritina and one in the genus Septaria. Pace made a detailed review on the Taiwanese freshwater snails among which he dealt with four species of Clithon, four of Neritina and one of Septaria. As a part of the taxonomie study ef Japanese neritids, the comparison ef the Japa- nese speeies with the Taiwanese speeies is made in order to elucidate a faunal relationships within Neritidae and to eontribute new knowledge on freshwater neritid fauna in Taiwan. Materials Specimens used in this study were eolleeted at the rivers of northern or central Taiwan in April, 1985. Their localities are as follows (Map 1) : 1. Tungkang, I-lan (Lanyang Hsi). 2.

Furthermore, he regarded N. pulchetta Recluz as a synonym of IV. sowerbiatna and N. interTupta Recluz as that of N. avellana. How- ever, Tryon (1888) eonsidered that pulchetla, avellana and faba are all probable synonyms of sozverbiana and that interrztpta pessesses all the characters of N. nucleolus Morelet, 1857. Hirase (1934) applied Theodoxus (Ctithon) sower- bianus and T. (C.) faba to Japanese species, but Hirase and Taki (1954) identi- fied C. fthba with C. sowerbianu$. Thereafter, Japanese workers allocated Japanese species into Clithon sowerbianus. On the other hand, Benthem Jutting (1956, 1963) used the names C. faba to Javanese species and C. sowerbianza to New Guinean one. Paee pointed out that the most commonly used name for these snails was Ctithon so2verbianus (R/6cluz) and stated that for the sake of stability it would be worthwhile to appeal to the International Commission en Zoological Nomenclature to preserve this name. In examining the syntype speci- mens of Neritina･ sowerbiana R/ecluz, 1842 (Museum d'Histoire Naturelle, Geneve and Museum National d'Histeire Naturelle, Paris) and N. faba Sowerby, 1836 (British Museum), the present author confirmed that these species were identi- cal and considered it inadequate that Hirase and Taki used sozverbianus to Japanese species. Therefore, Clithon faba (Sowerby) should be used for this specles. Pace assigned this species to the subgenus Vittoctithon by the characters that the shell was covered by a smooth periostracum and the co]or pattern was quite variable. However, I consider it inadequate to use these characters as diagnoses of the subgenus and could not distinguish them from the subgenus Clithon s. str. by the shell, opercular and radular characters. Subgenus Pictoneritina Iredale, 1936. 4. (;lith{m (Pictoneritina) tht(m'astoma (Sowerby, 1833). (Fig. 4) Localities and habitats: Takangko, 3 specimens.

Remarks: Pace (1973) allocated this species to the subgenus Neripteron, sinee no explanatioll was given for the changes in taxonomic position by Kuroda and Habe (1961), However, the subgenus Dostia is characterized by much areuated shells and thieker opercula than in the subgenus Neripteron and trape- zoid eentral teeth of radulae. Therefore, Dostia is aeeeptable as the subgenus of the genus Neritina･. Subgenus Vittina Baker, 1923. 7. IVeritina (Vittina) turrita (Gmelin, 1791).

However, I admitted a differentiation of Vittoida from Vittina in the shell, opercular and radular eharacters. Thus, I alloeate .this species under the subgenus 7ittoida, Genus Septaria Ferussae, 1807. Subgenus Septaria s. str. 11. Septaria (Septaria) poraellana (Linnaeus, 1758).

Septaria junghuhni werd beschreven door Von Martens (1881: 23, pl. 4, fïg. 13- 15) als Navicellajunghuhni waarbij hij een manuscriptnaam gebruikte van Herklots. Eén van de belangrijkste kenmerken van deze soort is het feit dat het septum tong- vormig vooruit steekt, dit bijvoorbeeld in tegenstelling tot Septaria porcellana (Lin- lineata twee andere soorten uit naeus, 1758) en Septaria (Lamarck, 1816), Indonesië, binnen is. drie heel waar het septum holvormig naar gebogen Deze soorten staan goed afgebeeld in Van Benthem Jutting (1956: fig. 31-33), waarbij de figuren 31 en 33 respectievelijk S. porcellana en S. lineata voorstellen. Het probleem wordt door figuur 32 gevormd. Van Benthem Jutting noemt de afgebeelde soort S. borbonica (Bory de St. Vincent, 1803). Dit is echter geenszins het geval. De type-lokaliteit van deze soort is het eiland Bourbon, het tegenwoordige Réunion, in het westelijk deel andere oceanische eilanden in van de Indische Oceaan.

ABSTRACT The family Neritidae has representatives in tropical and subtropical regions that occur in a variety of environments, and its known fossil record dates back to the late Cretaceous. However there have been few studies of molecular phylogeny in this family. We performed a phylogenetic reconstruction of the family Neritidae using the COI (722 bp) and the 16S rRNA (559 bp) regions of the mitochondrial genome. Neighbor-joining, maximum parsimony and Bayesian inference were performed. The best phylogenetic reconstruction was obtained using the COI region, and we consider it an appropriate marker for phylogenetic studies within the group. Consensus analysis (COI +16S rRNA) generally obtained the same tree topologies and confirmed that the genus Nerita is monophyletic. The consensus analysis using parsimony recovered a monophyletic group consisting of the genera Neritina , Septaria , Theodoxus , Puperita , and Clithon , while in the Bayesian analyses Theodoxus is separated from the other genera.

Except for some predation-resistant limpets in shallow-water marine environments, limpets are not well adapted to intense competition and predation, leading to the prediction that they originated in refugial habitats where exposure to predators and competitors is low. A survey of fossil and living limpets indicates that the limpet form evolved independently in at least 54 lineages, with particularly frequent origins in early-diverging gastropod clades, as well as in Neritimorpha and Heterobranchia. There are at least 14 origins in freshwater and 10 in the deep sea, E F with known times ranging from the Cambrian to the Neogene.

Rehder Research Curator, Division of Mollusks Introduction An outstanding patroness of the arts and sciences in eighteenth- century England was Lady Margaret Cavendish Bentinck, Duchess of Portland, wife of William, Second Duke of Portland. At Bulstrode in Buckinghamshire, magnificent summer residence of the Dukes of Portland, and in her London house in Whitehall, Lady Margaret— widow for the last 23 years of her life— entertained gentlemen in- terested in her extensive collection of natural history and objets d'art. Among these visitors were Sir Joseph Banks and Daniel Solander, pupil of Linnaeus. As her own particular interest was in conchology, she received from both of these men many specimens of shells gathered on Captain Cook's voyages. Apparently Solander spent considerable time working on the conchological collection, for his manuscript on descriptions of new shells was based largely on the "Portland Museum." When Lady Margaret died in 1785, her "Museum" was sold at auction. The task of preparing the collection for sale and compiling the sales catalogue fell to the Reverend John Lightfoot (1735-1788). For many years librarian and chaplain to the Duchess and scientif- 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 121 ically inclined with a special leaning toward botany and conchology, he was well acquainted with the collection.

From every species, collected at 26 stations (20 at South-, and 6 at North- Andaman), mostly in running waters, are given conchological, anatomical, ecological-biological and zoogeographical remarks. In the General Part the distribution of the found species in the running waters between headwaters and mouth-region is shown. The zoogeographical position of the Freshwater Gastropods is characterized by the dominance of malayo-pacific elements.* 1.

Riedel2 Keywords: tropical river, fluvial gastropods, ecology, distribution, ontogeny, protoconchs The tropical Matutinao River was investigated to study factors determining the distribution of the extant gastropods. Since eco­ logical zonation and life-cycles are somewhat correlated, we followed both research avenues and in particular focused on early ontogenetic strategies, discriminated by detailed studies of corresponding shell features. Twenty-six gastropod species, almost all of which are distributed over whole Cebu Island, occurred in the small Matutinao River. The specific associations of river sections, and ecological demands and life-cycles of gastropods are characterized. Of special interest are planktotrophic neritoi- dean larvae, which are usually carried to the sea and develop in the marine environment, but in rare cases remain and success­ fully metamorphose in freshwater. The biogeographic background and evolutionary consequences of the results are discussed.

Haynes* Abstract A total of thirteen species of the freshwater neritid limpet Septaria, that are found in the Indo - Pacific re- gion, are described. Fifty one nominal taxa are held in European and American Museums of which only 13 are regarded as valid. Specimens were collected from the streams and rivers of Fiji, Samoa, American Samoa, Vanuatu, Solomon Islands, French Polynesia, New Guinea, New Caledonia, Guam, Ponepe, South India, Mauritius, Seychelles and the Philippines between 1983 to 1997. They were dissected to reveal their reproductive anatomy, radula and operculum. Type specimens and other Septaria {Navicella) specimens held in Natural History Museums were matched with those recently collected. The valid species are: S. apiata (LE GUILLOU in RÉCLUZ, 1841), S. borbonica (BORY DE ST. VINCENT, 1893), S. bougainvillei (RÉCLUZ, 1841), S. cumingiana (RÉCLUZ, 1842), S. janelli (RÉCLUZ, 1841), S.livida (REEVE, 1856), S. luzonica (Souleyet in RÉCLUZ), S. macrocephala (LE GUILLOU in RÉCLUZ, 1841), S. porcellana (LINNAEUS, 1758), S. sanguisuga (REEVE, 1856), S. suffreni (RÉCLUZ, 1841), S. taitana MOUSSON, 1869, S. tesselata (LAMARCK, 1816). Key Words: Septaria, freshwater, tropical islands, Neritimorpha. Introduction Septaria species are brackish and freshwater neritimorph limpets that inhabit tropical, mainly fast flowing, island streams in the Indo - Pacific region.

    PREDATION ON HARDEST MOLLUSCAN EGGS BY CONFAMILIAL SNAILS (NERITIDAE) AND ITS POTENTIAL SIGNIFICANCE IN EGG-LAYING SITE SELECTION YASUNORI KANO1 AND HIROAKI FUKUMORI1,2 1Department of Marine Ecosystems Dynamics, Atmosphere and Ocean Research Institute, The University of Tokyo, 5-1-5 Kashiwanoha, Kashiwa, Chiba 277-8564, Japan; and 2Graduate School of Agriculture, University of Miyazaki, 1-1 Gakuen-kibanadai-nishi, Miyazaki 889-2192, Japan Correspondence: Y. Kano; e-mail: [email protected] (Received 12 December 2009; accepted 14 May 2010) ABSTRACT Neritid snails (Gastropoda: Neritimorpha) protect their eggs in a hard capsule, of tough conchiolin, reinforced by mineral particles derived from the faeces and stored in a special sac near the anus and oviduct opening. Predation on this arguably hardest of molluscan egg capsule is described and illus- trated here; neritids of the freshwater to brackish-water genera Clithon and Vittina, generally classified Downloaded from as herbivores, feed facultatively on the eggs of various confamilial species after breaking the reinforced capsule lid by means of prolonged radular rasping. Intensive predation pressure by these common inhabitants in Indo-West Pacific coastal streams may have given rise to the remarkable egg-laying be- haviour of Neritina on the shells of other living snails. Our laboratory examination showed that Neritina species deposited clusters of egg capsules more frequently on the living shell than on other http://mollus.oxfordjournals.org/ substrates, and that the predation rate was significantly lower on this moving ‘nursery’. Predation rate was even lower on the small egg capsules of Clithon and Vittina themselves, which were deposited one by one in the depressions on the rough surfaces of stones.
