Four species of Melithaeidae from Singapore waters are described and depicted: Melithaea ochracea (Linnaeus, 1758), Mopsella rubeola (Wright & Studer, 1889), M. retifera (Lamarck, 1816), and Acabaria robusta (Shann, 1912). Variation and synonymy are discussed. |

The phylogenetic relationships of the scleractinian genus Psammocora with the other genera traditionally included in the family Siderastreidae and some Fungiidae are assessed based on combined skeletal and molecular data. P. explanulata differs from the other examined congeneric species (P. contigua, P. digitata, P. nierstraszi, P. profundacella, P. superficialis, and P. stellata) in possessing interstomatous septa between adult corallites, costae, and in having continuous buttress-like structures joining septal faces (i.e., fulturae) which typically occur in fungiids. These characters are shared with Coscinaraea wellsi but not with the remainder of the examined siderastreids (the congeneric C. columna, and Anomastraea irregularis, Horastrea indica,... |

Three new species of Anthoathecatae (Cnidaria, Hydrozoa) of the rare genus Clathrozoella Stechow, 1921, Clathrozoella abyssalis spec. nov., C. bathyalis spec. nov. and C. medeae spec. nov., are described from New Zealand and Antarctic waters. Along with the previously known C. drygalskii (Vanhöffen, 1910) the genus Clathrozoella now numbers four species. Details of the skeleton, hydranths, nematocysts and gonophores are described and discussed, as is also the position of the newly established family Clathrozoellidae. |

Forty-six species of the superfamily Plumularioidea (Hydrozoa, Cnidaria) and some material identified to the generic level, collected by the CANCAP and Mauritania-II expeditions of the Rijkmuseum van Natuurlijke Historie (now Nationaal Natuurhistorisch Museum) in the period 1976-1988, are described, as well as two other species that were used in the present study. In addition to the descriptions, synonymy, variability and geographical distribution are discussed; autoecological data and measurements are also presented. The new species described here are: Aglaophenia svobodai spec. nov., Streptocaulus caboverdensis spec. nov., S. chonae spec. nov., Antennella confusa spec. nov. and Nemertesia anonyma spec. nov. All species are figured. The general... |

Sarcodictyon catenatum Forbes, 1847, is a common species in the Atlantic and the Mediterranean. However, often it has been mistaken for Rolandia coralloides Lacaze-Duthiers, 1900. On the basis of British and Mediterranean material we studied the main characters for distinguishing S. catenatum. We consider Rolandia coralloides Lacaze-Duthiers, 1900, to be a valid species and we assign to it all the material named Rolandia rosea by S. Weinberg (1978). Furthermore, a histological study confirmed that R. coralloides typically forms groups of polyps embedded in a common coenenchyme. Therefore, the possibility of transferring R. coralloides from Stolonifera to Alcyonacea is discussed. Evagorgia rosea Philippi, 1842, is here considered to be a nomen dubium. |

This is the first record of an association between a wentletrap species (Gastropoda: Epitoniidae) and coral species of the Euphyllidae (Scleractinia), i.e. Plerogyra simplex and P. diabolotus. While describing Epitonium hartogi spec. nov., special attention is given to the ontogenetic development within the eggcapsules, the structure and microsculpture of the opercula, the radulae, and the microsculpture on the radular jaws. These characters proved to be at least partly diagnostic in the epitoniid species Epitonium albidum, E. billeeanum, E. costulatum, E. hoeksemai, E. ingridae, E. lochi, E. millecostatum, E. pyramidalis, E. twilae, E. ulu and Nitidiscala tincta. Spiculae-like crystals covering the epitoniid egg-capsules are described; such crystals are... |

INTRODUCTION Bottom samples obtained by means of a Van Veen grab during the 1972 Saba Bank Expedition (CICAR cruises 34 and 35) appeared to comprise many samples with Foraminifera. This material was kindly put at my disposal by Dr. D. van Harten of the Geological Institute of the University of Amsterdam, where the material had been deposited. Complementary to this, a large amount of samples from many stations of the Saba Bank area were obtained from the residues in containers with larger material stored in the Rijksmuseum van Natuurlijke Historie at Leiden, but many of these residues contained only few Foraminifera. Dr. W. Vervoort of the Leiden Museum asked me to identify all the Foraminifera from both collections. As a result 1360 cardboard slides could... |
