    Description: Anthodus paniculatus Martius, reduced to a synonym of Hemiangium excelsum (H.B.K.) A. C. Smith by A. C. Smith, is reestablished here as Hemiangium paniculatum (Mart.) A. M. W. Mennega. H. excelsum in the present sense is now restricted to C. America, whereas H. paniculatum occurs in S. America.

    Description: Three new species of Salacia are described.\nSalacia bullata spec. nov., a liana, characterized by bullate leaves, was collected in Brazil, Territorio Amapa. It comes closest to S. amplectens. A.C. Smith\xe2\x80\x99s key (1940) should be amended to include a new group \xe2\x80\x98Amplectentes\xe2\x80\x99. This group, containing S. bullata and S. amplectens would be near \xe2\x80\x98Arboreae\xe2\x80\x99.\nSalacia alwynii, spec. nov., a vining species comes from Peru, Maynas, and is characterized by very large leaves and large cauliflorous flowers. It belongs to the species group \xe2\x80\x98Ellipticae\xe2\x80\x99 sensu Smith. It was also collected in Venezuela.\nSalacia paradoxa spec. nov. is a liana collected in Brazil along the Manaus-Caracarai road. Its long leaves are narrowly elliptic, its flowers are extremely small. In leaf characters it is strikingly similar to S. solimoesensis of Smith\xe2\x80\x99s species group \xe2\x80\x98Ellipticae\xe2\x80\x99, the shape of the disk, however, suggests the species group \xe2\x80\x98Crassifoliae\xe2\x80\x99. Specimens with fruits, collected in western Brazil may belong either to S. paradoxa or to S. solimoesensis.

    Description: A description is given of two new species in the genus Pristimera, P. dariense from Panama and P. caudata from Suriname. P. dariense differs by its flattened disk from the other New World species of the genus, but would fit in the subgenus Trochantha N. Hall\xc3\xa9 known from Africa.\nCuervea crenulata sp. nov. is a species collected in Brazil, Minas Gerais. Another species in Cuervea, C. mitchellae (Johnst.) A.C. Smith is considered as a synonym of C. kappleriana.\nHylenaea unguiculata sp. nov. is a new species from Suriname. The material on which the new species is based was at first erronously ascribed to the genus Tontelea with remarkably similar flowers.

    Description: Potamogeton filiformis Pers. in Nederland? P. filiformis wordt voor Nederland uitsluitend vermeld door Westhoff & Den Held, Plantengemeenschappen in Nederland, 1969, p. 54. Deze opgave is gebaseerd op niet-bloeiende exemplaren uit een collectie die in 1965 werd verzameld in het Veluwemeer. Bij herdeterminatie is echter gebleken dat deze collectie tot Juncus bulbosus behoort.

    Description: Species of the heteropod families Carinariidae and Pterotracheidae collected in the Mid North Atlantic Ocean in 1980 have been studied. The distribution of the species is given, as well as the morphological variation. It is concluded that two subspecies of Carinaria lamarcki actually have to be considered distinctly recognisable and sympatric species, to be called C. lamarcki and C. challengeri. The vertical distribution of the heteropods studied proves not to be restricted to the photic zone and diurnal vertical migration occurs among the larger species. The horizontal distribution of the two Carinaria species and of at least two populations of the Pterotrachea species coincides with the southern branch of the North Atlantic Current, while others are restricted to the subtropical waters. Consequently, the present heteropods have to be considered good indicators of water masses and currents.

    Description: Two new genera of the family Tubificidae inhabiting springs, wells and interstitial waters of a brackish lake in the West Indies are described. These are Spirospermoides stocki gen. et sp. n. and Krenedrilus papillatus gen. et sp. n. A detailed description of the morphological characters and genital organs is provided. A comparison with allied genera and species is also made. The occurrence of some other species of this family has been recorded.

    Description: Description of a new species of Metaniphargus, M. venezolanus, from a cave in northern Venezuela. This is the first representative of the hadziid group of genera of the family Gammaridae to be found in South America. It is closely related to certain Caribbean, insular taxa.

    Description: A worldwide list of species that have to be assigned to the genus Hemicypris is given. H. exigua n. sp. and H. barbadensis n. sp. are described. A redescription is given of H. reticulata (Klie, 1930), a species from Paraguay, which was also encountered in the Antillean islands. Descriptions of chaetotaxy are made according to the system of Broodbakker & Danielopol (1982). The morphology of the limbs of the three species is similar to that of the species of the genus Heterocypris encountered in the West Indies.\nLike in the genus Heterocypris, a considerable amount of variation in mean carapace length is found. The relative length of some setae seems to be fairly constant within, and characteristic of, each species.\nSome remarks are made on the ecology and the zoogeography of the three species.

    Description: A taxonomic revision of the scarabaeoid genus Hybosorus is given, including descriptions, nomenclatorial notes, figures of genital apparatus and other relevant parts, a key, and notes on distribution and bionomics. Lectotypes are designated for Hybosorus carolinus LeConte, H. crassus Klug, H. nitidus Lansberge, H. pinguis Westwood, H. roei Westwood, and Hybosoroides alluaudi Benderitter. Hybosorus arator (Illiger), H. carolinus LeConte, H. nitidus Lansberge (nov. syn.), H. illigeri var. nossibianus Fairmaire, H. pinguis Westwood, H. roei Westwood, H. arator subsp. arator (Illiger) sensu Endr\xc3\xb6di, 1957 (nov. syn.) and H. arator subsp. palearcticus Endr\xc3\xb6di (nov. syn.) are considered synonyms of H. illigeri Reiche. Problems concerning the type-species and some dubious names are discussed. Arguments are given for Hybosorus oblongus Dahlbom, H. pinguis Westwood, H. roei Westwood and H. carolinus LeConte being nomina oblita. Hybosorus laportei Westwood is considered a valid species and H. thoracicus Westwood a synonym of H. laportei (nov. syn.). Both were currently considered synonyms of H. illigeri Reiche. A new genus, Seleucosorus, is erected for Hybosorus punctatissimus Reiche. Hybosoroides alluaudi Benderitter, due to its close similarity to Hybosorus, is included in this revision. Hybosorus laeviceps Fairmaire is considered a synonym of H. baliensis Brancsik. Removed from Hybosorus are H. curtulus Fairmaire, being a Melolonthine, and H incultus P\xc3\xa9ringuey, being an Orphnine.

    Description: The fossils from Muara Kobun were collected by M. Schmidt (Royal Dutch Petroleum Company) as far back as 1902. Eighteen species, including two new ones (Cerithium (Gourmya) kobunense and Carditella witkampi) have been examined, the majority being gastropods whose combined stratigraphical ranges suggest a Preangerian age, with, however, the additional stipulation that perhaps some level high up in Tertiary f3 is involved rather than an age comparable to that of the Gelingseh faunas first partly described by K. Martin and the present writer. The molluscs from Pulu Senumpah were collected by L.M.R. Rutten in the period 1911-1913. There are no more than seven species, all gastropods, over half of which indicate best relationships with the Muara Kobun fauna, hence their being tentatively assigned the same age.
