| The study of a part of the material collected by the French oceanographic expedition "SEAMOUNT 1" made it possible to identify 21 species and one subspecies of hydroids of the families Haleciidae (4 species), Aglaopheniidae (7 species), Halopterididae (3 species), Kirchenpaueriidae (2 species and one subspecies) and Plumulariidae (5 species). Of these species, 10 have an Atlantic-Mediterranean distribution, 6 are cosmopolites, 4 are known from the north-eastern Atlantic, near to the area studied, and only one, Pseudoplumaria sabinae Ramil & Vervoort, 1992, is momentarily only known from Gorringe and Ampere Banks. |

| At the instigation of Dr. Joel W. Hedgpeth, Resident Director, Marine Science Center, Oregon State University, Newport, Oregon, U.S.A., I studied samples of hydroids, collected by Dr. John C. McCain and Dr. William E. Stout from submarine cliffs in the region around Palmer Station, Antarctica. The hydroids had been obtained during an examination of the zonation of rocky substrates in that area in the austral summer of 1968-1969. During this survey 0.25 m2 samples were scraped from the rocks at 5 feet intervals down to a depth of 50 feet and at 10 feet intervals from 50 to 100 feet. Dr. McCain and Dr. Stout were able to complete one such transect and a portion of another (Hedgpeth, in litt., see also McCain & Stout, 1969). The bulk of the material on... |

| The present study is a first attempt to comparing the hydroid faunas of the various Zoogeographie areas of the Atlantic Ocean. We restricted ourselves to species of the orders Antho- and Leptomedusae, of which 1050 species were taken into account. The classification of zoogeographic areas used follows Ekman and Briggs, with slight modifications; thus, the Strait of Gibraltar is here considered as a separate zoogeographic area due to its character of a transition zone between several areas in the Northeastern Atlantic Region. Species were arranged into Zoogeographic groups to compare the faunal composition of the various Zoogeographic areas. The Dice similarity index was used for each comparison. The fauna of North-eastern Region can be split into three... |

| INTRODUCTION At the request of Dr. Dennis M. Devaney, Invertebrate Zoologist, Bernice P. Bishop Museum, Honolulu, Hawaii, I investigated a number of Polynesian soft corals kept in the Museum mentioned. At the same time Professor Paul J. Scheuer, University of Hawaii at Manoa, Department of Chemistry, Honolulu, Hawaii, asked me to identify some octocorals from Enewetak Atoll (Marshall Is.) and from Ponape Island (Carolines). These collections include several well-known species which are not described in the present paper. I only mention their names with the localities added in parentheses: Cladiella pachyclados (Klunzinger, 1877) (American Samoa); Lobophytum borbonicum (Von Marenzeller, 1886) (Enewetak); Lobophytum pauciflorum (Ehrenberg, 1834) (Enewetak,... |

| An account is given of Sertularia vervoorti spec. nov., a small leptothecate species collected in coastal waters of southeastern Brazil. Specimens were found on brown algae, collected at depths of 15-20 m on the inner continental shelf off Espírito Santo state. This hydroid resembles Sertularia tumida Allman, 1877, S. linealis Warren, 1908, and S. longa Millard, 1958, but differs from these and other species of the genus in having an unusual bulge around the hydrothecal wall just distal to its insertion with the hydrocaulus. The colony form of S. vervoorti is more compact than in these species, and gonothecae are annulated rather than smooth as in S. linealis and S. longa. |

| The present collection was made on the south and west coasts of Madagascar between 90 en 465 meters depth and includes 17 species of calyptoblastic hydroids, belonging to six families: Campanulinidae, Lafoeidae, Campanulariidae, Syntheciidae, Sertulariidae and Plumulariidae. Twelve are recorded for the first time from Madagascar, while three of these are new for the Indian Ocean and one is described as new (Tulpa costata). Endemic species represent half of the collection and are numerically more important than cosmopolitan, tropical-indopacific, and southern species. A comparative study of bathymetrical characteristics of species from Madagascar and around the world allows to distinguish three groups of species: deepsea species, which have a very wide... |

| ALLGEMEINER TEIL. Die Bearbeitung der umfangreichen Scyphomedusen-Sammlung im Rijksmuseum van Natuurlijke Historie in Leiden ist nunmehr so weit vorgeschritten, dass sich eine Übersicht über dieselbe gewinnen lässt. In einer früheren Mitteilung wurde über die Cubomedusen berichtet, eine weitere zur Zeit noch nicht abgeschlossene Abhandlung wird sich mit den Rhizostomeen beschäftigen, während in der vorliegenden Arbeit alle übrigen sonst vorhandenen Scyphomedusen erörtert werden. Dieselben gehören den Ordnungen der Stauromedusen, Coronaten und Semaeostomeen an. Es liegen davon im ganzen über 160 Exemplare vor, die, systematisch geordnet, folgenden Genera und Species angehören: 1. Stauromedusae. Lucernaria campanulata Lamouroux. 2. Coronatae. * Nausithoë... |

| Twenty-eight hydroid species are recorded from the eastern Mediterranean and the northern part of the Red Sea, all material originating from the collections of the Museum of the Zoological Institute, Tel-Aviv University. The collection also included four species that could only be identified to generic level. Though the majority had previously been recorded from either the Mediterranean or the Red Sea, some constitute the first definite record from Israeli coastal waters. All material has been redeposited in the Tel-Aviv collection; slides and some duplicate samples are in the collections of the National Museum of Natural History (Nationaal Natuurhistorisch Museum, now also incorporating the Rijksmuseum van Natuurlijke Historie), Leiden, the Netherlands. |

| The North-eastern Atlantic and Mediterranean species of the family Cornulariidae are re-examined and taxonomically revised. This family is mainly characterized by the absence of sclerites. Up to now, only one genus, Cornularia Lamarck, 1816, has been assigned to the family. Studies of the internal and external anatomy of the European species of Cornulariidae, carried out for the first time on a comparative basis, leads us to propose a new genus, Cervera. New combinations of the species included in the family are proposed. The main characters of Cervera gen. nov. are the presence of a fine chitinous periderm, various communication canals in the stolons and the absence of a additional chitinous layer that covers the periderm. Cornularia atlantica Johnson,... |

| Four new genera, Rhytisma, Klyxum and Skamnarium (family Alcyoniidae) and Sansibia (family Xeniidae), are proposed to accommodate a number of species wrongly assigned to some established genera. A large number of the species concerned have been previously included in the genus Alcyonium, and remarks are made concerning the heterogenous nature of that genus. The reassignment of Parerythropodium hicksoni Utinomi, 1972, to Erythropodium, Alcyonium gracillimum Kükenthal, 1906, to Scleronephthya, and Clavularia hamra to Briareum is also discussed, and the existence of Funginus Tixier-Durivault, 1987, as a replacement name for Fungulus Tixier-Durivault, 1970, is highlighted. |

| Während eines sechswöchentlichen Erholungsaufenthaltes in Holland im Herbst 1920 hatte ich Gelegenheit, die Anthozoensammlung in 's Rijks Museum van Natuurlijke Historie in Leiden zu besichtigen. Den grössten Teil der Sammlung habe ich in Leiden selbst bestimmt; eine Anzahl Stücke, deren anatomische Untersuchung mir wünschenswert erschien und über die ich im Folgenden berichte, sandte Herr Professor van Oort auf meinen Wunsch nach Breslau. Es ist mir ein aufrichtiges Bedürfnis, Herrn Professor van Oort für sein liebenswürdiges Entgegenkommen auch an dieser Stelle meinen herzlichsten Dank auszusprechen. Ordnung: ZOANTHARIA. Palythoa brochi n. sp. Fundort: Guineaküste (ohne Angabe des Sammlers). 1 Kolonie. Im Leidener Museum fand ich eine aus dem Golf von... |

| The specific diversity of fossil crinoids from the Much Wenlock Limestone Formation at Dudley, Worcestershire, and in Shropshire differ by an order of magnitude. The latter are relatively depauperate and include only about six nominal species. Over 165 years ago, a specimen from Coalbrookdale, Shropshire, was identified as Cyathocrinites tuberculatus Miller (= the taxocrinid flexible Protaxocrinus tuberculatus (Miller)). This specimen, although indifferently preserved, is distinct from other Silurian crinoids of the British Isles and is described herein as a monobathrid camerate, Macrostylocrinus? jefferiesi sp. nov. This species has a moderately large, conical dorsal cup with at least 20 arms, broad primibrachials, a granular surface sculpture and no ray... |
