| Durch die Aufstellung des neuen Systems der Rhizostomeen (vergl. meine früheren Mitteilungen (12—15), insbesonders meine „Studien über Rhizostomeen..." (15)), hat sich die Nachuntersuchung zahlreicher Typenexemplare als notwendig erwiesen. Die Originalbeschreibungen der Autoren lassen vielfach Angaben gerade über jene anatomischen Merkmale vermissen, die auf Grund der neueren Untersuchungen für die Beurteilung der systematischen Stellung der einzelnen Formen von Wichtigkeit geworden sind. Eine Anzahl solcher Originale Haeckels konnte bereits bei Gelegenheit der Bearbeitung der Sammlung des Kopenhagener Museums untersucht werden (16), über die Untersuchungsergebnisse weiterer aus dem ehemaligen Museum Godeffroy in Hamburg stammender Originale Haeckel's und... |

| The present paper is divided into two parts. In the first, all Campanian, Maastrichtian and Danian ophiuroids known to date from the extended type area of the Maastrichtian Stage, are described and illustrated. The geographic and stratigraphic distribution of this diverse echinoderm group are documented. A total of twenty-one genera (one of them new) and thirty-seven species (seven of them new) are recorded from the Campanian-Danian of Liège-Limburg and the Aachen area (Germany). The following taxa are new: Ophiocten? yvonnae sp. nov., Stegophiura? trispinosa sp. nov., Deckersamphiura inusitata gen. et sp. nov., Ophiarachna? martinblomi sp. nov., Ophiolepis? falsa sp. nov., Ophiomusium lux sp. nov., and Mesophiomusium decipiens gen. et sp. nov. Additional... |

| Bivalve species of the mytilid genus Lithophaga, including a new one, are recorded from Indonesian mushroom corals (Scleractinia, Fungiidae). True associations with live hosts including L. laevigata, L. lessepsiana, L. lima, L. punctata spec. nov., and L. simplex, while specimens of L. malaccana and L. mucronata have been found in bore holes in encrusted or dead parts of infested corals. |

| The newly liberated, immature medusae of H. scandens, Hebella furax, H. muscensis, and the liberable eumedusoid of H. dyssymetra are described. The taxonomy of the medusa-producing Hebellinae is revised in the light of life cycle features. Due to inconsistencies between skeletal and medusan features, Hebellopsis is merged into Hebella. The new genus Anthohebella is proposed for the hebellids with swimming gonophores. All the nominal species referred to Hebella and Hebellopsis are discussed; out of the 45 nominal species referred at least once to Hebella and Hebellopsis, 15 are retained as valid: 11 are referred to Hebella and four to Anthohebella gen. nov.; 12 nominal species are considered conspecific with currently recognized species referred to the... |

| When Clark (1921) cleared the genus Linckia from superfluous synonyms, he could give no opinion on Linckia rosenbergi Von Martens 1866, p. 63 from Amboina. The unique holotype was in the Berlin Museum and hence not easily accessible to him, the species had not been described again. In his key Clark lays the stress on Von Martens' remark: "Die Porenfelder liegen zwischen den zwei Reihen grösserer Plättchen an der Armseite dicht aneinander, ohne alle Unterbrechung (wie bei Ophidiaster suturalis Müll. & Troschel), aber die Poren behalten dieselbe Anordnung in runde Gruppen (Felder) von circa 10 Poren bei". Clark interpreted this as follows: "Poriferous areas between superomarginals and inferomarginals in an unbroken, continuous series, more or less... |

| Systematic taxonomy requires thoughtful, detailed and structured descriptions of species characters, and essential additional data for effective comparison with other specimens. Crinoid terminology is commonly misused or at best confused. The purpose of this paper is to facilitate this process by encouraging a standard methodology which would make comparisons of fossil crinoid taxa easier for all. An ordered tabulation of those characters that should be considered in any description of a fossil crinoid is provided and implemented in describing a Scottish Llandovery (Lower Silurian) disparid crinoid Pisocrinus cf. campana S.A. Miller. |

| Hydroid distribution patterns along a horizontal ecocline in the Rio Formoso/Rio Ariquindá/Rio Porto Alegre system, a small and seasonally poikilohaline estuary on the tropical northeast coast of Brazil, were investigated. Collecting was undertaken during the dry season, in November 1993, by diving (with and without SCUBA). Nine stations were sampled on a transect extending from a reef outside the river mouth to a mangrove system at the upper end of the estuary. Four major regions were distinguished along the ecocline based on numerical analyses of hydroid species/station location data: (1) nearshore reef — a sandstone ledge outside the entrance of the estuary; (2) river mouth — a sandy and shelly flood-tidal delta area inside the entrance of the Rio... |

| It is a well-known fact that in many species of reef-corals the form of different colonies is largely subject to external influences that affected it during its growth. Not only in different colonies is this variability found, but also parts of the same colony may offer a striking contrast when compared with one another. One of the causes that modify the growth-form of various colonies of reef-corals, especially of the branching ones, is the action of the waves that roll in upon the reef after they have been more or less dissolved at the edge. These waves constantly sweep over the tops of the coral-colonies so as to prevent them to grow in height above a certain level. Together with the larger colonies whose tops are constantly in contact with the waves... |

| Sponge diversity and community composition in bathyal cold water coral reefs (CWRs) were examined at 500-900 m depth on the southeastern slopes of Rockall Bank and the northwestern slope of Porcupine Bank, to the west of Ireland in 2004 and 2005 with boxcores. A total of 104 boxcore samples, supplemented with 10 trawl/dredge attempts, were analyzed for the presence and abundance of sponges, using microscopical examination of (sub)samples of collected coral branches, and semi-quantitative macroscopic examination. Approximate minimum size of identified and counted sponge individuals was 1 mm. Literature data were added to the Porcupine Bank results to compensate for a less intensive sampling program in that location. Species richness and abundance were... |

| Two new Ceriantharia, Pachycerianthus curacaoensis and Arachnanthus nocturnus, both from the Caribbean region, are described. It is recommended to avoid the terms proto- and metamesenteries in taxonomie descriptions. The cnidom of the Ceriantharia is discussed; a subdivision of the spirulae (=b-rhabdoids) and penicilli ( = p-rhabdoids) differing from that of Schmidt (1972) is given. The anoplotelic character of the terminal tube of the penicilli (Schmidt, 1972) is doubted on the basis of light microscopical investigations. Mainly on the basis of the study of Botruanthus benedeni (Torrey & Kleeberger, 1909) (Botrucnidiferidae), the 2 newly described species (respectively belonging to the Cerianthidae and the Arachnactidae), and of the data available in... |

| Recent brachiopods collected by CANCAP IV and VI expeditions to the south-east North Atlantic, in the vicinity of the Canary and Cape Verde Islands, belonging to Neocrania, Hispanirhynchia, Stenosarina, Terebratulina, Eucalathis, Argyrotheca, Megathiris, Phaneropora, Megerlia, Kraussina, Dallina, Thecidellina and Pajaudina have been identified. As with the brachiopods previously identified from the CANCAP I-III expeditions, the CANCAP IV and VI material is Mauritanian in affinity and shows a close relationship with Lusitanian brachiopods from the Gulf of Gascogne. There is a lesser affinity with Mediterranean brachiopods, with isolated Senegalian and Caribbean elements present in the Cape Verde Islands. |
