The type material of Oswaldella billardi Briggs, 1938, has been re-examined and a complete description and figures are presented. The study of that material has allowed to reconsider the systematic position of all the material previously assigned to O. billardi and to determine that part of it belongs to another species. Since it is clearly different from the remaining species of the genus, it is described as Oswaldella erratum spec. nov. Resumen: Se ha revisado y redescrito el material tipo de Oswaldella billardi Briggs, 1938. Su estudio ha permitido reconsiderar la posición sistemática de todo el material anteriormente asignado a O. billardi y, así, determinar que parte del mismo pertenece a otra especie. Ya que dicha especie es claramente diferente de...

In de vorige aflevering van de serie 'Met Naturalis in zee' (Onderwatersport september 2003) werd een indruk gegeven van de expeditie naar Bali die door Naturalis was georganiseerd. Enkele bijzondere vondsten kwamen aan bod. In deze aflevering twee door Bert W. Hoeksema ontdekte onbekende diersoorten van Bali, het zuurtjeskoraal, een slak die daarop leeft en enkele van hun naaste familieleden. Zowel bij de koralen als de slakken gaat het om bijzonder kleurrijke dieren.

During a visit to the Fiji Islands, of about three weeks in March, 1949, through the kind help of Mr. Harold Gatty at Suva I had the opportunity to make trips to various coral reefs. On one of these trips, on March 18, to the reef of Tomberua, a small island to the south east of the large island Viti Levu, I collected an extensive material of various species of the genus Montipora. Among this material there is one colony of Montipora monasteriata (Forsk.), apparently the first to be reported from the Pacific region, as Crossland (1941, p. 35) states: "It is remarkable that the species, which is not uncommon in the Red Sea, has not appeared in any collection outside this area except in Gravier's from the Gulf of Aden." Forskål's (1775) short description of...

INTRODUCTION This paper forms the second part of the report dealing with the Faviidae collected during the Snellius Expedition. For the general introduction I refer to part I (Wijsman-Best, 1974). The genera dealt with in the present article, Favites, Goniastrea, Platygyra, Oulophyllia, Leptoria, Hydnophora and Caulastrea were with three exceptions collected at the same localities as the specimens of Favia. For the explanations of localities 1-17 I refer to article I. The additional three localities are (see map fig. 1): 18. Amboina (18 May 1830). By reef and shore collecting on 6th May some material was obtained at Wainitoe. From 2-8 May the mantri Erie accompanied Dr. P. H. Kuenen on his trip to the neighbouring island Haroekoe and collected animals on...

The merits of Em. Prof. Dr W. Vervoort in the field of systematic copepodology are evaluated, such within the context of his personal approach towards science as well as towards his students. It is concluded that Vervoort's work continues to exert a major influence on the study of taxonomy and of biogeography of free-living copepods up to the present day.

A phylogenetically based comparative analysis of onshore-offshore distribution patterns of mushroom coral species (Scleractinia: Fungiidae) was made to reconstruct an evolutionary scenario for differentiation in fungiid shelf habitats. This phyloecological study integrates data on fungiid distribution patterns along environmental gradients on the Spermonde Shelf, SW Sulawesi, with a recently published phylogeny reconstruction of the Fungiidae. A mushroom coral fauna of 34 species was used to compare their distributions by use of 50-m2 belt quadrats in transects (1) from the mainland to the shelf edge, (2) around reefs with regard to predominant wind directions, and (3) over bathymetrical reef zones. Species association ordinations were made for each of the...

The Sultanate of Oman harbours rich populations of sponges, especially in the four coral reef areas (Musandam Peninsula, Muscat coast & Daymaniyat islands, coasts of Masirah Island, and the Khuriya Muriya Islands). Up till now, apart from a few incidental samples, the sponges of Oman were known only from five dredge stations made by the John Murray Expedition 1933-1934 off the south coasts of Oman, near the Khuriya Muriya Islands, between 13.5 and 1415 m. Descriptions of the sponges obtained in these dredges were published by Burton (1959) and the specimens are deposited in the collections of the Natural History Museum, London. To complement these dredge samples, we recently obtained samples collected by SCUBA and shore collecting, mostly from the...

This study describes the in situ effects of four bioactive sponges on their neighbours at three different locations and two depths in the Spermonde Archipelago, SW Sulawesi, Indonesia. The natural rates of interaction between the sponge species and eight possible competitive invertebrate groups were defined and quantified in circular subplots, this was repeated 25x for each of the four species and for each location and depth. Most interactions occurred with other sponges and with corals. Coral overgrowth by the four target species caused necrosis in more than 85 % of these interactions, whereas this was less than 25 % in sponge overgrowths. These results suggest that the toxins are used in spatial competition and that the concentrations of the bioactive...

Sixteen out of the seventeen species of shallow-water starfishes reported with certainty from Inhaca Island and Maputo Bay were collected by the author. The seventeenth, Archaster angulatus, was recorded from there by Jangoux (1973). An identification key to these species, both in English and in Portuguese is presented. Four species have not been mentioned previously from Inhaca waters, viz. Astropecten monacanthus (because of earlier incorrect identifications), Monachaster sanderi, not known to occur further south than Zanzibar, Fromia milleporella and Ophidiaster hemprichii, which were not previously known to occur south of Madagascar. Stellaster equestris was found washed ashore on a sandy beach a little north of Maputo. The earlier recorded presence in...

During antarctic macrozoobenthos research, colonies of Monobrachium were found on small bivalves. The species problem of the genus Monobrachium is discussed and it is stated that there are three species. However, the widespread species Monobrachium parasitum might be a species-complex comprising several species. This can only be confirmed by rearing experiments and/or molecular investigations. Host specificity and the factors influencing the infection of the bivalve species are shown. The impact of the infection is demonstrated to be harmful to the host bivalve, although not of a parasitic nature. The phenomenon of bipolarity within the genus Monobrachium is discussed.

A check-list of mushroom corals (Fungiidae) is given with annotations on their distribution in Madang Lagoon, northern Papua New Guinea, Bismarck Sea. A total of 36 fungiid species is recorded from this locality, which is more than from any other studied so far. One species, Cantharellus jebbi spec, nov., is new to science. It is the only monostomatous mushroom coral species known that is entirely encrusting. It also represents the first record of a recent Cantharellus species in the IndoMalayan region.

In 'Met Naturalis in zee' van mei 2004 komt brandgevaar onderwater aan de orde. Aanleiding is een onderzoek aan brandkoralen, in het Engels 'fire corals' genoemd. Duikers en snorkelaars leren deze Millepora koralen snel herkennen na onbedoeld contact met het koraaloppervlak. Uit kleine poriën in dat gladde opppervlak steken haarfijne tentakels die netelkapsels bevatten. Daar brandt iemand zich meestal geen tweede keer aan. Dat kan heel anders bij dieren die zo goed gecamoufleerd zijn en zo venijnig pijn doen, dat het slachtoffer zich vaak niet realiseert wat hem is overkomen en ook niet direct ziet wie de boosdoener is.
