| Lohowia koosi, a new species and new genus in the family Alcyoniidae, is described from Lord Howe Island, Australia. The new taxon has dimorphic polyps and a similar morphology to some of the flat, lobe-less nominal species of Lobophytum. The new taxon is clearly distinguished, however, by the possession of large, heavily armed autozooids, polypary surface sclerites in the form of large spindles that protrude through the surface, extremely large interior sclerites and base surface sclerites in the form of rods, spindles and ovals. |

| 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. |

| The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus flavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral disc had four lobes (I. quadrilobatus) or eight (Synactinernus flavus) – we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number. |

| Twenty-one (sub)species of Leptolida (Hydrozoa, Cnidaria) of the familes Haleciidae and Campanulariidae are described and figured, originating from collections made during the CANCAP and Mauritania- II expeditions of the Rijksmuseum van Natuurlijke Historie (now Nationaal Natuurhistorisch Museum) to the north-eastern Atlantic in the years 1976-1988, visiting waters around the Azores, Canary Islands, Madeira, Cape Verde Islands and off Morocco and Mauritania. This material largely concerns well known species, the majority of which needs no detailed description. Exceptions are i.a. Halecium liouvillei Billard, 1934, Halecium sibogae marocanum Billard, 1934, Clytia arborescens Pictet, 1893, and Laomedea pseudodichotoma Vervoort, 1959. These species are... |

| 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... |

| Southern African coral communities form a continuum from the more typical, accretive reefs in the tropics of Mozambique to the marginal, southernmost African distribution of this fauna in KwaZulu- Natal. While the latter are limited in size, they are gaining increasing attention as they provide a model for the study of many of the stresses to which these valuable systems are globally being subjected. Soft coral cover, comprising relatively few species, exceeds that of scleractinians over much of the southern reefs, and the coral communities attain a high biodiversity at this latitude on the East African coast. A long-term monitoring programme has revealed small yet significant changes in community structure on the reefs in recent years, concurrent with... |

| A new species of coral inhabiting barnacle Cantellius cardenae spec. nov. (Crustacea, Cirripedia: Pyrgomatinae) is described. This barnacle was found on the staghorn coral Acropora (Isopora) brueggemanni (Scleractinia: Acroporidae). It is characterized by having transversally elongated scuta and narrow terga with a spur length more than half of the total tergal length. This species belongs to the secundus group of Cantellius, which includes barnacles with transversally elongated scuta, and which are limited to the Acroporidae. The distribution of C. cardenae supports the hypothesis that structurally specialized pyrgomatines occupy a more limited variety of hosts than do morphologicaly generalized ones. |
