| In his article on the distribution of Lymnaea glabra in the Netherlands, den Doop (1913 : 41) remarked that the mollusk fauna of this country had not much been studied. Miss Scholten (1913 : 348) agreed with this opinion, she thought that our mollusk fauna was only known to a very few conchologists. Miss Scholten believed that it would be useful if shell collectors from different places should publish their records with exact dates and localities, and she started in her publication by giving the distribution of 61 Dutch land and freshwater snails, known to her since 1912. Van der Sleen (1914 : 450) supported the idea to come to a better knowledge of the Dutch mollusk fauna; he enlarged Scholten’s list with ten nonmarine gastropods, he gave new localities... |

| Bibliography of the freshwater Pearlmussel Margaritifera margaritifera (Linnaeus, 1758) [Mollusca: Pelecypoda] The freshwater pearlmussel, described by Linnaeus as Mya margaritifera is one of the most important molluscs existing. It belongs with only a few congeneric fossil and recent species to the distinct family Margaritiferidae. The distribution of the species is Holarctic (figs. 1-2), being known from western, northern and central Europe, and via Siberia to Japan. In North America it is found at the northeast coast of the United States and East Canada. The habitat requires clean, cold and streaming freshwater. The life cycle of Margaritifera margaritifera and its reproduction are unique within the bivalves (fig. 3). From the fertilized eggs grows a... |

| This brief survey is based on the material collected by Dr. P. Wagenaar Hummelinck in 1936/37, 1948/49, and 1955. Station numbers only are cited; they refer to the “Description of new localities” in Volume IV of this series (1953; marine habitats p. 56-77) and to a “Third list of localities” which will be published in a forthcoming volume. Other localities, which are not numbered, are, as a rule, briefly described in the text. Material assembled by a few other collectors has been added to Hummelinck’s collection. The names of the collectors are always mentioned, abbreviated as follows: Av.: R. Aveledo, Caracas Be.: J. G. van den Bergh, Aruba BL.: T. Blok, Curaçao Bo.: Mrs van den Bos, St Maarten Co.: R. M. Collens, Tobago Ga.: Wiesje and Hendrikje, the two... |

| After studying the holotype of Engina schrammi Crosse, 1863, it became evident that the genus Risomurex Olsson & McGinty, 1958, is based on misidentified shells. Material recently collected at the Caribbean coast of Costa Rica included a new species, Risomurex mosquitensis, which is prefered to be considered the type-species of Risomurex. Relations with congeneric species are discussed. St. Thomas is designated type-locality for Ricinula rosea Reeve, 1846. |

| Conus clarus Smith is redescribed and considered a valid species from the south coast of West Australia to Victoria. A lectotype of C. segravei Gatliff is designated, it is a junior synonym of C. clarus. The holotype of C. kenyonae Brazier is studied and considered a juvenile specimen of C. distans Hwass. Specimens known as “C. lizardensis” and “C. tegulatus” from the coast between Dampier and Onslow in N.W. Australia are described as C. dampierensis nov. spec., a light colour forma is found on offshore islands. C. reductaspiralis Walls, originally a subspecies of C. nielsenae Marsh, is redescribed and considered a valid species; the distribution is from Cape Leveque to North West Cape, possibly further south. The species complex of C. lischkeanus... |

| Several Conus species of the coast of Oman are revised. Conus stocki n. sp. is described from Masïrah Island. For C. ardisiaceus Kiener, 1845, a neotype is designated. A lectotype is selected for C. luctificus Reeve, 1848. C. lischkeanus tropicensis Coomans & Filmer, 1985, has a disjunct range in the Indian Ocean. The recorded distribution of C. parvatus sharmiensis Wils, 1986, is enlarged from the Red Sea to the coast of Oman. c. quasimagnificus Da Motta, 1982, is provisionally considered a subspecies of C. pennaceus Born, 1778. |

| The present study is based on the well-known publication “Caribbean Seashells” by Warmke & Abbott (1961); its data are not repeated here, but a large number of mainly small species were added. Most data from “Gegevens over Mariene Gastropoden van Curaçao” by De Jong & Kristensen (1965) have been included. Furthermore most of the photos of species in “A survey of the littoral Gastropoda of the Netherlands Antilles and other Caribbean Islands” by Coomans (1958) are reproduced. The figures of species treated by us and occurring in “Caribbean Seashells”, in “The Western Atlantic Marine Mollusks, described by C. B. Adams” by Clench & Turner (1950) or in “American Seashells” by Abbott (1974) are referred to. |

| The marine fauna of the American Atlantic coast between Cape Cod and Cape Hatteras, the Virginian area, is placed by zoogeographers in different provinces: in the Transatlantic, or in the Boreal province. It is sometimes considered to be a province of its own, or only a transition between the Boreal and Carolinian province. The mollusk fauna of the Virginian area is compiled and compared with the faunas north and south of the area. As endemism is low, there is no reason to consider the Virginian area an autonomous zoogeographical province. The fauna is too much different from that of the Carolinian area, to combine both in one Transatlantic province. As most of the species are of boreal origin, there is less reason to consider the Virginian area as a... |

| The holotype of Conus pusio Sowerby I, 1834, is traced in the National Museum of Wales. This specimen also represents the holotype of C. melvilli Sowerby III, 1879, which fact makes both taxa objective synonyms. Since the name C. pusio is preoccupied by Hwass, 1792, the valid name for the species is C. melvilli. The holotype is a unique specimen; although mentioned from Key West, its locality is unknown. Conus melvilli “Sowerby” in Perry, 1939, from Florida was renamed C. perryae Clench, 1942. |

| Columbella dormitor Sowerby, 1844, was placed by the malacologists in the genera Columbella, Pyrene, Parametaria (all Columbellidae), and in Mitromorpha (Turridae). It is a rare species, living in deeper water in the southern Caribbean. The species belongs to the Columbellidae; however, it is different from all existing genera. A new taxon is erected for the species, Minipyrene. |

| The systematic place of “Cypraea” mus Linné is discussed, and it is concluded that the species belongs in Siphocypraea (Akleistostoma). The “varieties” tuberculata Gray and bicornis Sowerby should be withdrawn; they are only forms with callosities. Callus formations are often found in Cypraeidae. The distribution has been compiled from definite locality data; it covers the Caribbean coast of Colombia, and the coast of Venezuela as far as East of Paraguaná. S. mus does not occur around Curaçao or any other island of the West Indies. “Cypraea” surinamensis Perry belongs in the genus Propustularia. It is a Caribbean species, localities in Africa being incorrect. The locality data are compiled from the literature, most records date from the nineteenth century.... |

| In 1864 an anonymous list of species of the West Indian marine mollusks was published in Denmark. There were only twenty copies printed, seven of which were lost during transportation to the West Indies (CLENCH et al., 1947—1948, p. 23). The author was HENDRIK JOHANNES KREBS (1821—1907), Fig. 117, a Danish apothecary who lived on St. Thomas, Virgin Islands, from 1843 to 1870. Being the owner of a wholesale firm, he travelled throughout the West Indies, which gave him an opportunity to collect shells and plants. His species list was entitled: “The West-Indian Marine Shells with some remarks. A manuscript printed for circulation between collectors.” It was published by W. Laub’s Widow & Chr. Jorgensen, at Nykjöbing, Falster. As this work is very rare, a... |

| A biography of H. E. van Rijgersma is given, with the genealogical register of his family. The zoological and historical literature, in which he was mentioned, is discussed. Van Rijgersma's illustrated manuscripts on botany (1868) and malacology (1875) of St. Martin, and his correspondence with malacologists, were discovered in the United States and studied. The recent mollusk fauna of St. Martin is summarized, consisting of 550 species, of which 136 are new to the fauna of that island. |

| After our studies about the marine mollusks of St. Martin, (COOMANS 1963a, 1963b), this publication will deal with the land and freshwater shells of the island. The non-marine mollusks of St. Martin were already fairly well known at the end of the last century (MAZÉ 1890, p. 22—34), who mentioned 36 species, mainly collected by H. E. VAN RIJGERSMA. VERNHOUT (1914) compiled from the literature the land and freshwater mollusks of the Netherlands Antilles, and he listed 37 species from St. Martin (not including 12 brackish water species). VERNHOUT’S list was entirely copied by SCHEPMAN (1915). Many specific names have changed since 1914, and more collecting was done on St. Martin during the last decades. This publication will cover all the species of... |
