| A lectotype has been assigned for Placosmilia? robusta Umbgrove, 1925. This taxon, although fitting into the original diagnosis of Placosmilia, is not defined by the emended diagnosis of Alloiteau and later authors. Specimens from the Upper Maastrichtian of The Netherlands, that were formerly wrongly attributed to Galaxea fasciculata (Lamarck, 1816), a homonym of the extant species Galaxea fascicularis (Linnaeus, 1758), belong to Placocoenia macrophthalma (Goldfuss, 1826). The specimen depicted as P. macrophthalma by Umbgrove does not belong to this taxon and is placed in open nomenclature. |

| Two species of sea anemones with a conspicuous marginal ruff of frond-like structures encompassing the tentacular crown occur on the Chilean coast. Oulactis concinnata (= Isoulactis chilensis) (Drayton in Dana, 1846) is re-described in detail and further information is provided for Oulactis coliumensis (Riemann- Zürneck & Gallardo, 1990) (= Saccactis coliumensis) (both Actiniidae). The distribution of O. concinnata from Playa Las Salinas, Perú (9°19’10’’S, 78°26’30’’W), to the region of Valdivia, Chile (39°47’S, 73°21’W), lies within a zoogeographical unit known as the Peruvian Province. Re-description of O. concinnata is based on examination of 10 specimens collected between 1975 and 2003, and on observations of about 50 living anemones in their... |

| 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... |

| 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... |

| INTRODUCTION The species of the genus Priapulus occur in rather cold water. Hence, their shallow-water distribution is restricted to northern and southern waters (fig. 1); there are only a few isolated records from sub-tropical localities. However, in deep water the genus apparently has a world-wide distribution (fig. 2). The northern species (P. caudatus De Lamarck) and the southern species (P. tuberculatospinosus Baird) from shallow water are well defined but the specimens from the deep sea present systematical problems. In my survey of the Priapulida (Van der Land, 1970) I could not answer the question of their identity, because I had seen only very few specimens from deep water and not a single one from the tropical deep sea. Meanwhile I could study... |

| A new genus and species of azooxanthellate solitary coral, Monohedotrochus capitolii, are described in the subfamily Caryophylliinae, based on 42 specimens, most collected off Santa Catarina and Rio Grande do Sul states, southern Brazil. The new genus is characterized by being solitary and attached, having a monocyclic base, hexamerally arranged septa in four or five cycles, lacking paliform lobes and having a papillose columella. Oxysmilia epithecata Cairns, 1999, and O. circularis Cairns, 1998, are transferred to the new genus.

Um novo gênero e espécie de coral solitário azooxantelado são descritos para a subfamília Caryophylliinae, com base... |

| Die Kenntnis der Ciliatenfauna der Salzgewässer von höherer Konzentration als Meereswasser ist heute noch als sehr unvollständig zu betrachten. Nur wenige Autoren haben sich eingehender mit der Biologie dieser Wässer beschäftigt. Einerseits ist ein Bestreben wahrzunehmen eine möglichst vollständige Inventarisation zu geben (Butschinsky, Bujor), wobei aber vielfach ein Zweifel an der Richtigkeit der Bestimmungen nicht zu vermeiden ist; anderseits sind die Mitteilungen über dem Artenreichtum der untersuchten Gewässer weniger ausführlich und die Autoren beschränken sich auf eine Beschreibung einiger wenigen Arten (Entz, Florentin, Gajewskaia, Kirby), ein Verfahren, das jedoch für das Studium abnormaler Milieus dem ersten vorzuziehen ist, weil eben durch das... |

| This study is the first review of Zoantharia species in the South China Sea and Gulf of Thailand. In addition to past literature records, new field observations are added from previously unexamined countries and regions. In total 16 species are listed, 15 of which belong to suborder Brachycnemina, and only one to suborder Macrocnemina. Two species are undescribed. The lack of Macrocnemina species is not likely indicative of a low diversity of this suborder in the South China Sea and Gulf of Thailand, but instead of an absence of research below shallow subtidal depths. As the majority of the new records from this study were randomly compiled by researchers who are not experts of Zoantharia, specific surveys by experts are needed in these two marine regions.... |

| Since the study of the genus Corallimorphus was started, the main taxonomic character used to separate species has been the ratio of the number of marginal tentacles to that of the discal ones. Polyps with a marginal:discal (m:d) tentacle ratio of 2:1 and 4:1 collected by the “Challenger” expedition were described as two distinct species, Corallimorphus rigidus and Corallimorphus profundus respectively (Moseley, 1877a, 1877b; Hertwig, 1882, 1888). This feature remained important in the taxonomy of the genus. For example, Fautin et al. (2002) subdivided the genus Corallimorphus into two groups of species: Corallimorphus rigidus, C. ingens, C. atlanticus, C. denhartogi (ratio of marginal: discal tentacles 2:1) were referred to the «rigidus» group. C.... |

| 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. |
