A new endemic Actinia species (Actiniaria: Actiniidae) from the central Macaronesian Archipelagos Naturalis
Hartog, J.C. den; Ocaña, O..
The presence of some endemic taxa of the genus Actinia from Madeira and the Canary Islands is discussed. A new species, Actinia nigropunctata, is described, and some characters of the poorly known Actinia virgata are discussed. In addition, we discuss the main characters proposed by Schmidt (1971) to distinguish species of Actinia.

A new genus and species of soft coral (Octocorallia: Alcyonacea: Alcyoniidae) from Lord Howe Island, Australia Naturalis
Alderslade, P..
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.

A new genus and species of stoloniferous octocoral (Anthozoa: Clavulariidae) from the Pacific coast of North America Naturalis
Williams, G.C..
A new genus and species of intertidal octocoral is described from the Pacific coast of North America. The new taxon is placed in the stolonbearing family Clavulariidae, and although superficially similar in appearance to species in both the genera Clavularia and Sarcodictyon, it exhibits some unique characters to differentiate it from these taxa.

A new species of Allopathes (Cnidaria: Antipatharia) from the eastern Atlantic Naturalis
Opresko, D.M..
A new species of antipatharian coral, Allopathes denhartogi, is described from the eastern Atlantic. The species is distinguished from the two other species in the genus by spines that are larger, less dense and not arranged in verticils. Furthermore, the colony appears to reach a smaller size and has relatively fewer ramifications compared to the other species.

A new species of Sphenotrochus (Scleractinia: Turbinoliidae) from the Late Miocene (Tortonian) of Chile Naturalis
Cairns, S.D..
A new species of azooxanthellate Scleractinia, Sphenotrochus denhartogi, is described from the Late Miocene (Tortonian, Navidad Formation) of Chile. Comparisons are made to three other closely related species which, based on their distinctive costal morphology, form a species complex: S. claibornensis, S. senni, S. denhartogi, and S. auritus. This is the first record of Sphenotrochus from the west coast of South America.

A study of the Xeniidae (Octocorallia, Alcyonacea) collected on the "Tyro" expedition to the Seychelles with a description of a new genus and species Naturalis
Janes, M.P..
An examination of xeniid octocorals was carried out on specimens held in the National Museum of Natural History, Naturalis, Leiden, Netherlands. Samples collected during the Tyro expedition to the Seychelles Islands in the Western Indian Ocean were identified. Six species belong to the genera Cespitularia, Heteroxenia, and Ovabunda are described; five of these are new records for this location. Three new species belonging to the genera Anthelia, Cespitularia and Ovabunda are illustrated. In addition, a new genus belonging to the family Xeniidae is introduced accompanied by scanning electron micrographs of its sclerites. Gross morphology and the ultra-structure of the sclerites indicate there are some similarities in this new genus with Anthelia. However,...

A survey of the genera Sarcodictyon Forbes, 1847, and Rolandia Lacaze-Duthiers, 1900, (Anthozoa: Octocorallia) in the North-eastern Atlantic and the Mediterranean Naturalis
Ocaña, O.; López-González, P.J.; Núñez, J.; García-Gómez, J.C..
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.

Actiniaria from Ria de Arosa, Galicia, northwestern Spain, in the Netherlands Centre for Biodiversity Naturalis, Leiden Naturalis
Hartog, J.C. den; Ates, R.M.L..
Twentysix species of sea anemones (Actiniaria) collected in Galicia, northwestern Spain are present in the collection of the Netherlands Centre for Biodiversity Naturalis. They are listed and discussed. The cnidom of seventeen species is surveyed. Diadumene cincta is not a recent immigrant in western Europe. Sagartia luciae is (re)assigned to the genus Diadumene. The presence of Sagartia troglodytes in the Mediterranean is doubtful at best.

An undescribed lobate ctenophore, Lobatolampea tetragona gen. nov. & spec. nov., representing a new family, from Japan Naturalis
Horita, T..
Lobatolampea tetragona gen. nov. & spec. nov. was collected from coastal waters of Ise Bay, near Toba, Pacific coast of middle Japan. It assumes a medusoid bell-shape when floating, but is nearly discshaped when resting on the bottom. It is characterized by four C-shaped gonads present on the distal part of the subpharyngeal meridional canals, beyond the oral end of the comb rows. “Primitive” oral lobes are also formed and ctenes are found at the site of the presumptive auricles. The morphology of this species differs from any previously described larval or adult form, and is intermediate between the orders Cydippida and Lobata. The larvae are of the cydippid type.

An unusual sea anemone from slope depths of the tropical west Pacific: range extension and redescription of Isactinernus quadrilobatus Carlgren, 1918 (Cnidaria: Actiniaria: Actinernidae) Naturalis
Fautin, D.G.; Hartog, J.C. den.
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.

Atlantic Haleciidae and Campanulariidae (Hydrozoa, Cnidaria) collected during the CANCAP and Mauritania-II expeditions of the National Museum of Natural History, Leiden, The Netherlands Naturalis
Medel, M.D.; Vervoort, W..
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...

Biodiversity on the marginal coral reefs of South Africa: What does the future hold? Naturalis
Schleyer, M.H.; Celliers, L..
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...

Cantellius cardenae spec. nov. (Cirripedia: Pyrgomatinae) from Acropora (Isopora) brueggemanni (Brook, 1893) (Anthozoa: Acroporidae), a case of host specificity in a generalist genus Naturalis
Achituv, Y.; Hoeksema, B.W..
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.
