Biological results of the snellius expedition XXII. Octocorallia from the Malay Archipelago (Part II)
Provedor de dados: 16
Autores: Verseveldt, J.
The material dealt with in this second part of "Octocorallia from the Malay Archipelago" comprises mainly specimens belonging to the family Nephtheidae. Most of these nephtheids were obtained during the cruise of the "Willebrord Snellius". In addition to this material I examined some specimens collected by the Siboga Expedition, which had to be identified or described again. Besides, there were in the Leiden Museum some unidentified colonies, obtained in Malayan waters. These, too, are now recorded. Several authors have already pointed out how difficult it is to identify Dendronephthya, owing to the unsatisfactory description by some previous authors, and because of the great number of variations within the same species. Suffice it to refer to the...

Brachiopods from the Valdeteja Formation (Pennsylvanian; Cantabrian Mountains, NW Spain)
Provedor de dados: 16
Autores: Martínez Chacón, M.L.; Winkler Prins, C.P.
After a short introduction on the lower Pennsylvanian (Bashkirian to lowermost Moscovian)Valdeteja Formation in its stratigraphical context, an overview of its brachiopod faunas is presented and their palaeoecological and palaeogeographic importance discussed. Two new genera of the Strophalosiidina, showing adaptations to a reef environment, are described. The genus Ovetina (type species O. truyolsi gen. et sp. nov.) is an aulostegid with a well developed ventral flange. Miroproductus (type species M. posadai gen. et sp. nov.) is an early richthofenioid, probably derived from an aulostegid such as Institina MUIR-WOOD &amp; COOPER, 1960.

On two new species of Holectypus Desor from the Senonian of South-Limburg near Maastricht, Netherlands
Provedor de dados: 16
Autores: Engel, H.
Up to now the genus Holectypus Desor (1842, p. 52) 1847, (cf. Mortensen, 1948, Monogr. IV 1, p. 26) in its restricted sense (with 4 genital pores) has not been recorded from the Senonian. So the two specimens described below as H. boschmai nov. spec. may have been remaniated and finally deposited in the Senonian of South-Limburg. They then may belong to the Jurassic species H. corallinus d'Orbigny, 1850. Though the preservation of two other specimens of Holectypus from the Limburg Senonian does not permit to decide whether a fifth genital pore is present, it is presumed there was. These two specimens are described as H. macrostomus nov. spec. As said, up to now no Senonian Holectypus is known with 4 genital pores. Holectypus boschmai nov. spec. (pl. XIV)...

A standardized method of describing fossils, using Echinoidea as an example
Provedor de dados: 16
Autores: Lewis, D.N.; Donovan, S.K.
The main purpose of a research paper in palaeontology, or any scientific discipline, is to spread information within the field. In this paper, suggestions are made concerning the structure and organisation of systematic palaeontological papers, using the Echinoidea as an example. A comprehensive table of echinoid morphological features is presented. It is intended that authors following these guidelines will be facilitated in writing research papers that enable expeditious retrieval of information.

Short note on three species of Ordovician Orchocladina (Demospongea, Porifera)
Provedor de dados: 16
Autores: Rhebergen, F.
The type and only specimen of Fibrocoelia tubantiensis Van Kempen, that was housed in the palaeontological collection of the Geological Institute of the University of Amsterdam, has been reposited in the Netherlands Centre for Biodiversity – Naturalis, Leiden, the Netherlands. Syltrochos pyramidoidalis Von Hacht, placed in an uncertain order and family by Finks &amp; Rigby, is revised on the basis of new material. This has revealed that the skeleton is composed of spheroclones, so that the species has to be assigned to the Astylospongiidae von Zittel. The species name Carpospongia langei Von Hacht is invalid, being a junior synonym of Carpospongia pogrebowi Asatkin.

Protosuberites denhartogi spec. nov., a new name for European ‘Prosuberites epiphytum’ (Demospongiae, Hadromerida)
Provedor de dados: 16
Autores: Soest, R.W.M. van; Kluijver, M.J. De.
The common NE Atlantic sponge species hitherto known under the name Prosuberites epiphytum (Lamarck, 1814), is differentiated from the South Australian type and other regional specimens. Spicule size and form, although generally similar, are subtly different. Australian P. epiphytum apparently persistently overgrow the thallus of algae, possibly as part of a symbiotic association, and this is not known for European specimens. In view of these facts and taking into account the disjunct distribution, it is proposed to assign the NE Atlantic populations to a new species. The genus Prosuberites has been restricted recently to species with single long tylostyles with heads embedded in a basal spongin plate, and both P. epiphytum and the new species do not...

Fossil and modern sponge fauna of southern Australia and adjacent regions compared: interpretation, evolutionary and biogeographic significance of the late Eocene ‘soft’ sponges
Provedor de dados: 16
Autores: Łukowiak, M.
The late Eocene ‘soft’ sponge fauna of southern Australia is reconstructed based on disassociated spicules and is used to interpret the paleoecology and environmental context of shallow marine communities in this region. The reconstructed sponge association was compared with coeval sponge assemblages from the Oamaru Diatomite, New Zealand, and with the modern ‘soft’ sponge fauna of southern coastal of Australia. Based on the predominance of shallow- and moderately shallow-water species, the late Eocene assemblage is interpreted to have inhabited waters depths of about 100 m. This contrast with the spicule assemblage from New Zealand, which characterized deeper waters based on the presence of numerous strictly deepwater sponge taxa, and the absence of...

Observations on a living specimen of the giant hydroid Branchiocerianthus imperator
Provedor de dados: 16
Autores: Omori, M.; Vervoort, W.
The largest known solitary hydroid, Branchiocerianthus imperator (Allman, 1885), was first collected on June 17, 1875, with a trawl-net, off Boso Peninsula on the Pacific coast of Japan, during the Challenger Expedition; it was described as Monocaulus imperator Allman, 1885. On June 21, 1985, 110 years after its discovery, a living specimen was observed for the first time, using the submersible "Shinkai 2000". The species is a suspension feeder and a carnivore: a symbiotic shrimp was found associated with it. Recently the species has been recognized from photographs taken in deep water of the N.E. Atlantic by the French IFREMER/CEA Expedition, apparently the first Atlantic record.

New records of the Holothurians Thyone serrifera Oestergren (Dendrochirotida) and Leptosynapta bergensis (Oestergren) (Apodida)
Provedor de dados: 16
Autores: Kramers, P.G.N.
During a student trip to the Trondheimsfjord (Norway) in August and September, 1967, eight specimens of this species were dredged off Kivnæbnes (63o 32' Ν, 9° 51' E), from a depth of 50 to 200 m, bottom clay with shells. The calcareous ossicles in the body wall are exactly like the illustrations in Østergren (1898) and Mortensen (1924: 235). Figures 1 to 3 show copies of figures by Østergren and Mortensen, and a drawing made from one of my preparations. Thyone serrifera seems to have been found only once before (pers. comm. Brun, Panning) viz., by Østergren, the author of the species, who dredged it in the Trondheimsfjord near Rødberg (appr. 63o 28' Ν, 10° Ε). Mortensen (1924) cited this record with addition of the depth range 200-500 m, of which the...

Ueber Lychnorhiza malayensis Stiasny
Provedor de dados: 16
Autores: Stiasny, G.
Nicht ohne Zögern habe ich seinerzeit (1921) in meinen „Studien über Rhizostomeen" (2) die neue Species Lychnorhiza malayensis aufgestellt. Es lag mir damals nur ein einziges mittelgrosses Exemplar vor, das nicht geschlechtsreif war und überdies nicht alle Mundarme in normaler Ausbildung zeigte. Ein weiteres Bedenken bot der Fundort: Batavia, da doch alle bisher bekanntgewordenen Vertreter des Genus Lychnorhiza aus den brasilianischen oder westindischen Gewässern stammen. Ausschlaggebend für die Aufstellung der neuen Species war schliesslich der abweichende Typus des Gefässystems, das im Typenexemplar sehr deutlich erkennbar war und die Einreihung der neuen Art im System der Rhizostomeen ohne Schwierigkeiten ermöglichte. Seither habe ich besonders auf...

Phylogeography of the Sponge Suberites diversicolor in Indonesia: insights into the evolution of marine lake populations
Provedor de dados: 16
Autores: Becking, L.E.; Erpenbeck, D.; Peijnenburg, K.T.C.A.; Voogd, N.J. de.
The existence of multiple independently derived populations in landlocked marine lakes provides an opportunity for fundamental research into the role of isolation in population divergence and speciation in marine taxa. Marine lakes are landlocked water bodies that maintain a marine character through narrow submarine connections to the sea and could be regarded as the marine equivalents of terrestrial islands. The sponge Suberites diversicolor (Porifera: Demospongiae: Suberitidae) is typical of marine lake habitats in the Indo-Australian Archipelago. Four molecular markers (two mitochondrial and two nuclear) were employed to study genetic structure of populations within and between marine lakes in Indonesia and three coastal locations in Indonesia,...

Further studies on Octocorallia
Provedor de dados: 16
Autores: Verseveldt, J.
INTRODUCTION This paper is to be regarded as a continuation of my previous publication (Verseveldt, 1940 1)). Some three species, sufficient material of which for an anatomical examination was available, had then to remain undiscussed; they are: Semperina rubra Kö11., Anthothela macrocalyx (Nutt.) (= Suberia macrocalyx Nutting (1911) = Semperina macrocalyx (Nutt.) Kukenthal (1919)) and Sibogagorgia weberi Stiasny, which species have been examined by me in the same way as formerly the others. It has become clear to me that the second of the species mentioned cannot be considered as belonging either to the genus Suberia Studer or the genus Semperina Kö11. A close relationship with Anthothela grandiflora (M. Sors) caused me to decide on the name Anthothela...

Provedor de dados: 16
Autores: Voogd, N.J. de; Soest, R.W.M. van.
Sponges of the genus Petrosia (Demospongiae: Haplosclerida) are large and characteristic components of many Indonesian reefs. We identify and provide descriptions of seven species of Petrosia collected recently on SW Sulawesi reefs (Eastern Indonesia), two of which are new to science: Petrosia (Petrosia) alfiani spec. nov. and Petrosia (Petrosia) hoeksemai spec. nov. Additional species recorded are Petrosia (Petrosia) lignosa Wilson, 1925, Petrosia (Petrosia) nigricans Lindgren, 1897, Petrosia (Petrosia) plana Wilson, 1925, Petrosia (Strongylophora) corticata (Wilson, 1925) and Petrosia (Strongylophora) strongylata Thiele, 1903. The species are discussed and compared with Petrosia records from other Indonesian and neighbouring Indo-West Pacific areas. We...

Notes on Rhizocephala infesting species of the Anomuran genus Galathea
Provedor de dados: 16
Autores: Boschma, H.
During the work of the Ecological Survey of the University of Cape Town a few Crustacea of various groups were collected which proved to be infested with Rhizocephalan parasites. Remarks on one of these, a parasite of Galathea dispersa Bate, are given in the present paper, while notes are added on the data from the literature and on the structure of some other specimens 1). The Rhizocephala occurring as parasites of species of the genus Galathea belong to the genera Triangulus and Lernaeodiscus (family Lernaeodiscidae) or to the genus Galatheascus (family Peltogastridae). Moreover, one species of the genus Sacculina is known as a parasite of a Galathea, while Parthenopea subterranea Kossmann, a species usually infesting Callianassa, has been reported as a...

Biodiversity of shallow-water sponges (Porifera) in Singapore and description of a new species of Forcepia (Poecilosclerida: Coelosphaeridae)
Provedor de dados: 16
Autores: Lim, S.-C.; Voogd, N.J. de; Tan, K.-S.
A surprisingly high number of shallow water sponge species (197) were recorded from extensive sampling of natural intertidal and subtidal habitats in Singapore (Southeast Asia) from May 2003 to June 2010. This is in spite of a highly modified coastline that encompasses one of the world’s largest container ports as well as extensive oil refining and bunkering industries. A total of 99 intertidal species was recorded in this study. Of these, 53 species were recorded exclusively from the intertidal zone and only 45 species were found on both intertidal and subtidal habitats, suggesting that tropical intertidal and subtidal sponge assemblages are different and distinct. Furthermore, only a third of the fouling species of sponges from a previous study was...

Some nomenclatorial corrections to 'Investigations on Stylasteridae (Hydrocorals)' 1942
Provedor de dados: 16
Autores: Broch, H.
When discussing the genus Errina in my paper "Investigations on Stylasteridae (Hydrocorals),, (1942) I arrived at the conclusion held by Hickson (1912) that the species of the genus should be grouped in two, or possibly three, subgenera. It was pointed out that Hickson had erroneously used the designation "the Labiopora group" for the subgenus containing the type species Errina aspera (L.), and accordingly I proposed to name this subgenus Eu-Errina. For the other subgenus, viz., "the Errina group" of Hickson, the type species of which is Errina labiata Moseley, I introduced the name Labiata. A third group, viz., "the Spinipora group" of Hickson, was only casually mentioned by me, as I had no representative of this group at hand. The only species of this...

Provedor de dados: 16
Autores: Vervoort, W.
At the instigation of Dr. Joel W. Hedgpeth, Resident Director, Marine Science Center, Oregon State University, Newport, Oregon, U.S.A., I studied samples of hydroids, collected by Dr. John C. McCain and Dr. William E. Stout from submarine cliffs in the region around Palmer Station, Antarctica. The hydroids had been obtained during an examination of the zonation of rocky substrates in that area in the austral summer of 1968-1969. During this survey 0.25 m2 samples were scraped from the rocks at 5 feet intervals down to a depth of 50 feet and at 10 feet intervals from 50 to 100 feet. Dr. McCain and Dr. Stout were able to complete one such transect and a portion of another (Hedgpeth, in litt., see also McCain &amp; Stout, 1969). The bulk of the material on...

Distribution patterns in Atlantic hydroids
Provedor de dados: 16
Autores: Medel, M.D.; López-González, P.J.
The present study is a first attempt to comparing the hydroid faunas of the various Zoogeographie areas of the Atlantic Ocean. We restricted ourselves to species of the orders Antho- and Leptomedusae, of which 1050 species were taken into account. The classification of zoogeographic areas used follows Ekman and Briggs, with slight modifications; thus, the Strait of Gibraltar is here considered as a separate zoogeographic area due to its character of a transition zone between several areas in the Northeastern Atlantic Region. Species were arranged into Zoogeographic groups to compare the faunal composition of the various Zoogeographic areas. The Dice similarity index was used for each comparison. The fauna of North-eastern Region can be split into three...

Sertularia vervoorti (Hydrozoa: Sertulariidae), an undescribed species of hydroid from Brazil
Provedor de dados: 16
Autores: Migotto, A.E.; Calder, D.R.
An account is given of Sertularia vervoorti spec. nov., a small leptothecate species collected in coastal waters of southeastern Brazil. Specimens were found on brown algae, collected at depths of 15-20 m on the inner continental shelf off Espírito Santo state. This hydroid resembles Sertularia tumida Allman, 1877, S. linealis Warren, 1908, and S. longa Millard, 1958, but differs from these and other species of the genus in having an unusual bulge around the hydrothecal wall just distal to its insertion with the hydrocaulus. The colony form of S. vervoorti is more compact than in these species, and gonothecae are annulated rather than smooth as in S. linealis and S. longa.

North-eastern Atlantic and Mediterranean species of Cornulariidae Dana, 1846 (Anthozoa: Stolonifera) with the description of a new genus
Provedor de dados: 16
Autores: López-González, P.J.; Ocaña, O.; García-Gómez, J.C.; Núñez, J.
The North-eastern Atlantic and Mediterranean species of the family Cornulariidae are re-examined and taxonomically revised. This family is mainly characterized by the absence of sclerites. Up to now, only one genus, Cornularia Lamarck, 1816, has been assigned to the family. Studies of the internal and external anatomy of the European species of Cornulariidae, carried out for the first time on a comparative basis, leads us to propose a new genus, Cervera. New combinations of the species included in the family are proposed. The main characters of Cervera gen. nov. are the presence of a fine chitinous periderm, various communication canals in the stolons and the absence of a additional chitinous layer that covers the periderm.

Autores: Donovan, S.K.; Lewis, D.N.
The specific diversity of fossil crinoids from the Much Wenlock Limestone Formation at Dudley, Worcestershire, and in Shropshire differ by an order of magnitude. The latter are relatively depauperate and include only about six nominal species. Over 165 years ago, a specimen from Coalbrookdale, Shropshire, was identified as Cyathocrinites tuberculatus Miller (= the taxocrinid flexible Protaxocrinus tuberculatus (Miller)). This specimen, although indifferently preserved, is distinct from other Silurian crinoids of the British Isles and is described herein as a monobathrid camerate, Macrostylocrinus? jefferiesi sp. nov. This species has a moderately large, conical dorsal cup with at least 20 arms, broad primibrachials, a granular surface sculpture and no ray...

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...

The coral Montipora monasteriata (Forsk.) in the Fiji Islands
Provedor de dados: 16
Autores: Boschma, H.
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."

Evolutionary trends in onshore-offshore distribution patterns of mushroom coral species (Scleractinia: Fungiidae)
Provedor de dados: 16
Autores: Hoeksema, B.W.
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...

Tetractinellid and hadromerid sponges of the Sultanate of Oman
Provedor de dados: 16
Autores: Soest, R.W.M. van; Beglinger, E.J.
The Sultanate of Oman harbours rich populations of sponges, especially in the four coral reef areas (Musandam Peninsula, Muscat coast &amp; 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...

Sponge interactions with spatial competitors in the Spermonde Archipelago
Provedor de dados: 16
Autores: Voogd, N.J. de; Becking, L.E.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van.
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...

Monobrachium parasitum (Cnidaria: Hydrozoa) epizoic on antarctic bivalves and its bipolarity
Provedor de dados: 16
Autores: Jarms, G.; Mühlenhardt-Siegel, U.
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.

Het mysterie van de hellevuur zeeanemoon

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.

A new genus and species of sea anemone, Onubactis rocioi gen. et spec. nov. (Actiniidae) is described from the Atlantic coast of the southern Iberian Peninsula. The main features of Onubactis rocioi are: a smooth to corrugate scapus, a delicate scapulus provided with a ruff of non-adherent papillate outgrowths, absence of acrorhagi, more mesenteries distally than proximally, a weak diffuse sphincter, and presence of numerous spirocysts in the pedal disc. The new genus is discussed in relation to five other genera which are characterized by a distal ruff of columnar outgrowths: Actinostella Duchassaing, 1850; Oulactis Milne-Edwards &amp; Haime, 1851; Saccactis Lager, 1911; Isocradactis Carlgren, 1924; and Isoulactis Carlgren, 1959.

Notes on Hydrocorallia

Autores: Boschma, H.
I. Introduction. When using here the name Hydrocorallia for a group of corals, it is not intended to regard this group as a recognized systematic unit. Since Moseley (1880) placed the Stylasteridae with the Milleporidae in the Hydrocorallinae, a separate sub-order of the Hydroids, it has been sufficiently pointed out that the families Milleporidae and Stylasteridae have little in common, and that their respective relations are with Hydroids of systematically different groups. Broch (1914) maintains that the family Milleporidae traces its origin to that of the Corynidae, whilst in his opinion the family Stylasteridae is a highly specialized group that has been derived from the Bougainvilliidae. Stechow (1923) came to the same conclusion, he also placed the...

Autores: Donovan, S.K.; Jagt, J.W.M.
A single example of Oichnus excavatus Donovan &amp; Jagt, infesting the holasteroid echinoid Hemipneustes striatoradiatus (Leske), is reported from the upper Meerssen Member, Maastricht Formation (uppermost Maastrichtian), of the former Blom quarry, Berg en Terblijt, southern Limburg, The Netherlands. This is the first evidence that O. excavatus may be more widely distributed in the type area of the Maastrichtian than previously assumed. The embedment structure occurs just below the ambitus and close to the peristome, suggesting that the producing organism may have been ingesting detritus from the sea floor rather than filter feeding, the more usual interpretation of its behaviour.

A new and presumably now extinct species of Millepora (Hydrozoa) in the eastern Pacific
Provedor de dados: 16
Autores: Weerdt, W.H. de; Glynn, P.W.
A new species of hydrocoral, Millepora boschmai, is described from the Gulf of Chiriqui, Pacific Panamá. This species was first found in the early 1970's, but it has disappeared from this area as a result of the severe 1982-83 El Nino-Southern Oscillation (ENSO) event. Because the species has never been encountered outside the Gulf of Chiriquí, it is assumed that it was endemic to this area and that its disappearance marks an extinction event, representing the first documented case of a modern extinction of a tropical marine organism due to natural causes.

New observations on scleractinian corals from Indonesia: 2. Sipunculan-associated species belonging to the genera Heterocyathus and Heteropsammia
Provedor de dados: 16
Autores: Hoeksema, B.W.; Best, M.B.
Three Indonesian species of Heterocyathus and two of Heteropsammia are briefly diagnosed. Remarks are given on their synonymy, phenotypic variation, and ecology. All five species are found on soft substrata in the proximity of coral reefs and live in association with a sipunculan worm. This interspecific assocation is discussed with regard to whether it is mutualistic or parasitic.

How many hydrozoan species are there?
Provedor de dados: 16
Autores: Schuchert, P.
A list of all living hydrozoan species was compiled and analysed. The number of supposedly valid species was found to be around 3200. Considerable uncertainties exist due to the possibly high number of invalid nominal species. The total number of existing hydrozoan species cannot be estimated because the accumulation curve for new species shows no sign of convergence. Only in the Thecata, Narcomedusae and Trachymedusae is an estimate of the maximal number feasible. However, application of new methods, notably a molecular systematic approach, could drastically alter these predictions.

The impact of small benthic passive suspension feeders in shallow marine ecosystems: the hydroids as an example
Provedor de dados: 16
Autores: Gili, J.-M.; Alvà, V.; Coma, R.; Orejas, C.; Pagès, F.; Ribes, M.; Zabala, M.; Arntz, W.; Bouillon, J.; Boero, F.; Hughes, R.G.
Benthic suspension feeders are abundant in littoral and shallow sub-littoral ecosystems, where they feed on the plankton and on organic matter suspended in the water column. Recent studies indicate that active suspension feeders with powerful water filtration mechanisms (e.g., bivalve molluscs) may exert an important influence on the abundance and production of phytoplankton, and probably zooplankton as well. Passive suspension feeders, such as hydrozoans, have received less attention, and their effect on shallow planktonic communities is poorly understood. This paper presents evidence that hydrozoans, which make only a minor contribution to benthic community biomass, capture large amounts of zooplankton and seston, and that they may play an important role...

High evolutionary potential of marine zooplankton
Provedor de dados: 16
Autores: Peijnenburg, K.T.C.A.; Goetze, E.
Open ocean zooplankton often have been viewed as slowly evolving species that have limited capacity to respond adaptively to changing ocean conditions. Hence, attention has focused on the ecological responses of zooplankton to current global change, including range shifts and changing phenology. Here, we argue that zooplankton also are well poised for evolutionary responses to global change. We present theoretical arguments that suggest plankton species may respond rapidly to selection on mildly beneficial mutations due to exceptionally large population size, and consider the circumstantial evidence that supports our inference that selection may be particularly important for these species. We also review all primary population genetic studies of open ocean...

Some misapplied nomina nova in reef coral taxonomy (Scleractinia)
Provedor de dados: 16
Autores: Hoeksema, B.W.
Nomina nova should be used only to denote replacement names for preoccupied names, i.e. in the case of homonymy. Three examples of incorrect applications of nomina nova in scleractinian taxonomy are given. Coincidentally, in the cases discussed each wrongly proposed nomen novum concerns a new species so that there are no nomenclatorial consequences. For one of these species, Galaxea paucisepta Claereboudt, 1990, a lectotype is designated.

Taxonomic characters from the hydranths of live thecate hydroids: European Haleciidae (Cnidaria: Leptothecatae)
Provedor de dados: 16
Autores: Cornelius, P.F.S.
The hydranths of six species of hydroids of the family Haleciidae from NW Europe are described from life and compared. Notes are given on the hydranths of three other species, and general taxonomic comments on some others. Hydranth character-states are useful in defining and distinguishing Halecium species, but the characters may not be useful in routine identification by non-specialists. Halecium undulatum is recorded for the first time from Sweden, and from three localities in Norway whence there was just one previous record. Halecium halecinum may breed year-round in British waters.

In this paper we describe Suberites diversicolor spec. nov.

Initially this species was thought to be specific to anchialine lakes, but further comparison to coastal areas indicated that it is more widespread in inshore systems. We have used morphological characters to distinguish this species and a molecular marker to confirm that all types are the same species. Suberites diversicolor spec. nov. is encrusting or massive with small protrusions or larger globular branches. The external colour can be olive-green, blue, purple, red-orange, or orange-yellow.

Morphometric variation in two intertidal littorinid gastropods
Provedor de dados: 16
Autores: Queiroga, H.; Costa, R.; Leonardo, N.; Soares, D.; Cleary, D.F.R.
Here we investigate spatial variation in shell shape of Littorina saxatilis, an ovoviviparous species, and Melarhaphe neritoides, a species with planktonic eggs and larvae. Populations of both species were sampled in 6 sites located along the west coast of the Iberian Peninsula. Shell shape was studied using landmarkbased morphometric methods. Landmark data was used to estimate individual size and to describe shell shape. Prior to statistical analysis specimens were aligned using Generalised Procrustes Analysis (GPA). Ordinations based on GPA of landmark data and using Principal Components Analysis (PCA), revealed a clear spatial segregation of sites for both species, although this was more evident for L. saxatilis than M. neritoides. Statistical analysis...

Die Madreporaria des Naturhistorischen Reichs-Museums in Leiden : I. Die Genera Porites, Goniopora, Alveopora, Montipora

Autores: Stiasny, G.
Wenn ich mich dazu entschlossen habe, ein Verzeichnis der reichhaltigen Steinkorallen-Sammlung des Rijks Museum van Natuurlijke Historie in Leiden zu veröffentlichen, die zum grössten Teile aus dem malayischen Archipel stammt, geschieht dies hauptsächlich deswegen, weil die Litteratur über recente Korallen aus diesem an ihnen so reichen Gebiete überaus arm ist. Zusammenfassende Uebersichten der recenten Korallenfauna aus dem ostindischen Archipel finden wir allein in einer Arbeit BEDOTS (1) und aus jüngster Zeit in einer schönen Publikation UMBGROVES (20), der um die im Neogen dieses Gebietes zahlreich vertretenen Riffkorallen studieren zu können, die lebenden Korallriffe untersuchte.

Uitbreiding van het areaal van de mosdiertjes Tricellaria inopinata en Bugula simplex in het noordoosten van de Atlantische Oceaan (Bryozoa: Cheilostomatida)   In 2000 werd het mosdiertje Tricellaria inopinata op twee plaatsen bij Goes (Zeeland) aangetroffen. De soort is in 1985 beschreven aan de hand van materiaal van Venetië, waar ze kennelijk door scheepvaart is geïntroduceerd. Tricellaria inopinata is afkomstig uit het noorden van de Stille Oceaan. De soort komt nu ook in Zuid-Australië, Nieuw-Zeeland, Japan en Taiwan voor, en is daar waarschijnlijk geïntroduceerd. In 1996 werd deze soort voor het eerst aan de Atlantische kust van Europa waargenomen, in Galicië (NW Spanje). Waarschijnlijk tussen 1996 en 1998 koloniseerde de soort Zuid-Engeland in de...

Autores: Boschma, H.
The description of Stylaster stellulatus Stewart was based on a specimen obtained at Tahiti, the coral was stated to be extremely rare, and only found at one small island in the neighbourhood. The description contains all the peculiarities for a specific definition of the coral, the salient points of this description are here mentioned, partly in Stewart's own words (1878, pp. 41-43). "The corallum is of a bright rose colour, especially in the younger branches, the older parts being often more pale. The branches are usually quite cylindrical, though occasionally flattened at their tips; the general appearance being much like that of S. sanguineus, but it has a bluer rose tint, and is at once distinguished by the minute size of its calicles (1/67 of an...

Autores: Mastenbroek, N. van.
In het brakke water van de Zeeuwsche eilanden komen Bryozoën voor, die tot het geslacht Membranipora behooren en die zich van de andere soorten van dit geslacht onderscheiden door den vorm van de kolonie. De dieren liggen hier niet, zooals bij de meeste Membranipora's, tegen het substraat aan, maar vormen afstaande korsten, die tot groote, samengestelde klompen kunnen uitgroeien en die zich vasthechten aan palen en bruggen. Deze Bryozoën zijn door een aantal onderzoekers, die ze tot zeer verschillende soorten brachten, in Zeeland en het omgevende gebied gevonden. In „Flora en Fauna der Zuiderzee" vermeldt Mej. van Benthem Jutting (1922) dezen vorm als Membranipora membranacea (L.) var. erecta Loppens, naar aanleiding van de determinate van overeenkomstige...

Autores: Migotto, A.E.
The paper presents the results of a general survey of the hydroid fauna of the coastal region of the São Sebastião Channel, São Paulo State, Brazil. Intensive collecting in the intertidal and infralittoral zones, from 1984 to 1992, led to the discovery of many species, some of which are small and inconspicuous. Out of 59 species of hydroids (17 athecate and 42 thecate) described and illustrated, three are new records for the Atlantic Ocean, six for the western South Atlantic, and 21 for the Brazilian coast. The medusa stage of Asyncoryne ryniensis and the cnidome of 24 species are described for the first time. The paper also contains a synopsis of the hydroids recorded from the Brazilian coast, the list now including 107 species. Pseudostenotele...

Provedor de dados: 16
Autores: Donovan, S.K.; Portell, R.W.; Veltkamp, C.J.
Despite being diverse globally, Miocene echinoids are poorly known from Jamaica. Moderately diverse echinoids and other echinoderms have been identified mainly from fragmentary specimens collected from chalks and mass-flow deposits of the Lower Miocene Montpelier Formation, White Limestone Group, near Duncans, parish of Trelawny. This locality has yielded the most diverse association of fossil echinoderms known from the Miocene of Jamaica, including at least ten species in four classes. This fauna is comprised of the isocrinid crinoids Neocrinus sp. cf. N. decorus (Wyville Thomson) and Isocrinus sp.; the ophiuroid Ophiomusium? sp.; the asteroids Astropecten? spp.; and the echinoids Prionocidaris? sp., Histocidaris sp., Echinometra sp. cf.

Skeletons in confusion: a review of astrophorid sponges with (dicho-)calthrops as structural megascleres (Porifera, Demospongiae, Astrophorida)
Provedor de dados: 16
Autores: Soest, R.W.M. van; Beglinger, E.J.; Voogd, N.J. de.
We present a review of astrophorid species possessing calthrops megascleres as structural megascleres (including species with dichotriaene modifi cations, but excluding mesotriaene and trichotriaene bearing species). Radiating oxeas characteristic of most astrophorids are lacking in such sponges, but auxiliary oxeas are apparently present in some species. Th ese sponges are currently assigned to two families, Pachastrellidae with four nominal genera Dercitus, Stoeba, Dercitancorina, Halinastra (the latter two generally considered junior synonyms of Stoeba), and Calthropellidae with nominal genera Calthropella, Corticellopsis (usually considered a junior synonym), Pachataxa and Pachastrissa.

Madreporaria from the Togian Reefs (Gulf of Tomini, North-Celebes)
Provedor de dados: 16
Autores: Umbgrove, J.H.F.
INTRODUCTION The coral reefs of the Togian islands grow up as steep barrier reefs and atolls. Moreover small fringing reefs occur along the islands. The geological structure of the islands, as well as the history and morphology of the reefs are treated in a separate paper 1). I will here mention only one of the striking features of the reefs. The reefs are situated in a zone, famous for the unruffled calm and undisturbed quiet of the sea, because they are protected from the influence of both monsoons. In a curve from West to North they are sheltered against the North monsoon by the Northern arm of Celebes; on the South of this group the Eastern arm of Celebes breaks the influence of the South East monsoon, which, blowing across the Banda Sea is only...

Stylasterina in the collection of the Paris museum : III. Stylaster flabelliformis (Lamarck)
Provedor de dados: 16
Autores: Boschma, H.
The last description of the coral Stylaster flabelliformis (Lamarck) appeared a century ago (Milne Edwards &amp; Haime, 1857, p. 129). The cited authors listed in the genus Stylaster six at the time well-defined species, two of which, S. flabelliformis and S. gracilis, were characterized by having the "calices" exclusively on the lateral surfaces of the branches. From a modern point of view in the cited publication the specific characters were little clearly defined, consequently Broch (1936, p. 11) had to observe that the identity of S. flabelliformis is uncertain. Fortunately the species is well represented in the collections of the Paris Museum; during a visit in September, 1954, I made notes on the large colonies, while some small fragments were taken...

The new anthaspidellid taxon Brevaspidella dispersa is erected for specimens recovered from the Late Ordovician sponge assemblages of the island of Gotland, Sweden and the Dutch-German border region. In the latter area, they are collected from Early Pleistocene fluvial deposits of the Baltic River System, whereas those from Gotland are part of Late Pleistocene glacial or fluvio-glacial deposits. The provenance of both assemblages is uncertain, but they probably originated from an Ordovician basin in the northern Baltic Sea or the Bothnian Gulf, west of Finland. As yet, Brevaspidella dispersa gen. et sp. nov. is restricted to the Gotland-German-Dutch sponge association and has not been found in the assemblage of nearly-coeval ‘lavender-blue cherts’ and...

A remarkable new Middle Sandbian (Ordovician) hexactinellid sponge in Baltic erratics
Provedor de dados: 16
Autores: Botting, J.P.; Rhebergen, F.
A new species of complex hexactinellid sponge, Haljalaspongia inaudita, is described from fluvially transported blocks found in northwestern Germany, near the Dutch border, but which probably originated from the eastern Baltic region. The heavily folded wall is composed of multiple spicule layers, including dermal and gastral layers of acanthohexactines, and a central layer of sub-parallel monaxons. The monaxial layer is lined on one side by a reticulate array of smooth monaxons. The sponge is difficult to assign to any known fossil or recent group, but shares some features with the dictyospongioid family Docodermatidae.

Further Notes on the Ampullae of Millepora
Provedor de dados: 16
Autores: Boschma, H.
After a prolonged scrutiny of numerous colonies of Millepora in the collections of various museums I found, besides a number of colonies with open ampullae, ten specimens possessing ampullae with their coverings of a trabecular network. The chief details of these ampullae were described in a previous paper (Boschma, 1949 a). Afterwards I had the good fortune to obtain material of different species of Millepora from six localities showing ampullae in an undamaged state. These ampullae are figured and described in the present paper. I am greatly indebted to Mr. Harold Gatty of Suva, who enabled me to visit coral reefs in the Fiji Islands during the time I stayed in this locality (March, 1949). I want to thank Dr. C. H. Edmondson, curator, Bernice P. Bishop...

Lophopodella pectinatelliformis nov. spec. (Bryozoa-Phylactolaemata)
Provedor de dados: 16
Autores: Lacourt, A.W.
A new species of freshwater Bryozoa has been found at Patua, Sumatra by Dr. A. Holleman-Haye. It belongs to the genus Lophopodella which has an Aethiopean-Indian range. The genus Lophopodella is characterised by its large oval statoblast, large capsule and broad annulus. This annulus possesses one or more spines at the poles. These spines are studded with very small anchor-like hooklets. The genus Lophopodella is closely related to the genus Pectinatella. The statoblasts of the latter genus may bear large spines without hooklets or, on the other hand, a great number of small spines (or hooklets) which are directly placed on and around the entire margin, as e.g. in Pectinatella gelatinosa Oka. Characteristic of the new species of Lophopodella is that the...

The recent solitary mussid scleractinian corals

Autores: Wells, J.W.
INTRODUCTION In 1937 the writer, following Matthai (1928, p. 209), placed the solitary mussid genera Cynarina, Homophyllia, Rhodocyathus, Protolobophyllia, Sclerophyllia, Scolymia (Lithophyllia — placed in Mussa by Verrill in 1902, p. 130, and suspected of being only the young of colonial mussids by Pourtalès in 1871, p. 70) as subjective synonyms of the various colonial genera such as Lobophyllia, Symphyllia, and Mussa, on the assumption that these supposed solitary forms were based on early monostomatous (monocentric) stages of colonial forms. The late T. W. Vaughan and the writer later (1943, p. 194) adopted the same treatment. Wells followed much the same line in 1956 (p. 417-418), except that Homophyllia was once more recognized as a distinct genus....

Autores: Soest, R.W.M. van.
A new poecilosclerid sponge species Desmapsamma vervoorti spec. nov. is described from several Indonesian localities: Ambon, Jedan, Salayar, Komodo, Java, and Irian Jaya. The species was earlier reported from several Indo-Pacific localities as D. anchorata (Carter, 1882), a common Caribbean shallow water species. Comparison with Caribbean specimens makes it clear that Indo-Pacific specimens demonstrate small but consistent differences.

The giant barrel sponge Xestospongia testudinaria is an ecologically important species that is widely distributed across the Indo-Pacific. Little is known, however, about the precise biogeographic distribution and the amount of morphological and genetic variation in this species. Here we provide the first detailed, fine-scaled (&lt;200 km2) study of the morphological and genetic composition of X. testudinaria around Lembeh Island, Indonesia. Two mitochondrial (CO1 and ATP6 genes) and one nuclear (ATP synthase β intron) DNA markers were used to assess genetic variation. We identified four distinct morphotypes of X. testudinaria around Lembeh Island. These morphotypes were genetically differentiated with both mitochondrial and nuclear markers. Our results...

Autores: Owada, M.; Hoeksema, B.W.
Research on the evolution of the symbiosis between the boring mussel Fungiacava eilatensis (Bivalvia: Mytilidae) and its mushroom coral hosts (Scleractinia: Fungiidae), which requires phylogenetic reconstructions of both the Mytilidae and the Fungiidae, contributes to the understanding of the complexity of coral reef ecosystems. Previously, Fungiacava was regarded as a genus that had descended from Leiosolenus or as belonging to the subfamily Crenellinae, but no phylogenetic support has been obtained for this hypothesis. In the present study, the 18s rRNA sequences of ten mytilid species and the shell microstructures of 12 mytilids were investigated. The phylogenetic position of F. eilatensis is discussed in relation to its associations with its host...

Evaluation of the ecological function of amphitoxin in the reef-dwelling sponge Callyspongia (Euplacella) biru (Haplosclerida: Callyspongiidae) at southwest Sulawesi, Indonesia
Provedor de dados: 16
Autores: Voogd, N.J. de; Haftka, J.J.H.; Hoeksema, B.W.
The ecological function of the secondary metabolite amphitoxin produced by Callyspongia (Euplacella) biru is evaluated by a forced confrontation with the free-living scleractinian coral Fungia fungites at different exposure times. Our major goal was to determine whether such a forced confrontation with a spatial com­petitor would cause a significant change in the concentration of amphitoxin in the sponge tissue, indicating a regulatory mechanism of amphitoxin production. Firstly, the concentrations of amphitoxin of sponge fragments submitted to forced confrontation with a mushroom coral did not differ between the exposure times. Secondly, all sponge fragments, including the controls had a consistently lower amphitoxin concentration during the course of the...

The demise of Coelenterata and Madreporaria
Provedor de dados: 16
Autores: Land, J. van der.
Names of groups of organisms in the higher categories are being changed rather often, even when there is no need for it. This is allowed because the codes of nomenclature do not apply to group names above the family level. Regrettably this may lead to long periods of confusion. Examples are Coelenterata for which the new name Cnidaria was proposed in 1888 and Madreporaria for which the new name Scleractinia was proposed in 1900. The gradual replacement of the old names by the new names in scientific papers during the last 50 years was analyzed. The name Madreporaria virtually disappeared during this period and the name Coelenterata is now being used in only about 10% of scientific papers and had better be abandoned as well.

The occurrence of the sea anemone Sagartia elegans var. miniata, var. nivea and var. venusta in considerable numbers at three localities in the Netherlands is reported upon. Previous records of the species in Dutch coastal waters are reviewed. Most of these are considered as doubtful. Characters to distinguish S. elegans from S. troglodytes are discussed. Attempts are made to relate local occurrence of S. elegans with temperature data. Sagartia elegans is an autochthonous species in the Netherlands but its numbers vary considerably, and populations probably have no permanent character. In the past, populations presumably have been reduced and sometimes wiped out during relatively severe winters. Reinforcement of rest populations or recolonization is likely...

Gelegentlich der Durchsicht einiger älterer Planktonfänge aus dem malayischen Archipel in den Sammlungen des Rijks Museum van Natuurlijke Historie in Leiden fanden sich zahlreiche Entwicklungsstadien von Rhopilema hispidum (VANH.)

Provedor de dados: 16
Autores: Soest, R.W.M. van; Beglinger, E.J.; Voogd, N.J. de.
Based on collections assembled by Dutch expeditions to the Northwest African region, including the offshore islands in the neighbouring Atlantic, a taxonomic monograph of sponges of the genus Mycale is presented. Additional material from the region borrowed from the Zoologisk Museum of the University of Copenhagen and incidental samples made by individual collectors were also included. The combined collections contained sixteen species, nine of which are new to science: Mycale (Aegogropila) syringosimilis spec. nov., Mycale (Aegogropila) tenerifensis spec. nov., Mycale (Arenochalina) africamucosa spec. nov., Mycale (Carmia) atropha spec. nov., Mycale (Carmia) guineensis spec. nov., Mycale (Naviculina) cruzi spec. nov., Mycale (Paresperella) janvermeuleni...

Madreporaria from the Bay of Batavia
Provedor de dados: 16
Autores: Umbgrove, J.H.F.
INTRODUCTION In the Bay of Batavia there are patch-reefs and cays in different stadia of development. Some are small reefs still rather deep below sea level, other reefs bear a small sand cay. On the larger coral sand islands vegetation has developed ; moreover shingle ramparts and a moat have come into existence. The islands and reefs considered in this paper are situated South of a line which may be thought passing from Cape Pasir towards the Island Edam, so forming a boundary between the reefs in the Bay of Batavia and the northern group of Thousand Islands („Duizend eilanden"). The author studied these reefs in some detail and the results were published as early as 1928 1). In that amply illustrated paper data and considerations may be found on...

Taxonomy, Phylogeny and Biogeography of Mushroom Corals (Scleractinia: Fungiidae)
Provedor de dados: 16
Autores: Hoeksema, B.W.
The Fungiidae are mushroom corals that live in sublittoral habitats in the tropical Indo-Pacific. Their habitats are part of coral reefs or other marine substrata, which usually can be found in the proximity of the reefs. In the present taxonomic revision, the family is divided into 11 genera; one of which, Fungia, is subdivided into seven subgenera. A total of 40 species is described and figured, three of which are new to science. One species is renamed. The stratigraphic distribution is given for all the species recorded in fossil state. A tentative phylogenetic reconstruction down to the species level is given. The cladogram that is provided should be considered a working hypothesis and not a sound basis for a completely revised classification and...

Affinities of the family Sollasellidae (Porifera, Demospongiae). I. Morphological evidence
Provedor de dados: 16
Autores: Soest, R.W.M. van; Hooper, J.N.A.; Beglinger, E.; Erpenbeck, D.
Comparison of Sollasella digitata Lendenfeld, 1888, up until the present assigned to its own family Sollasellidae Lendenfeld, 1887 in the order Hadromerida, and Raspailopsis cervicornis Burton, 1959, assigned to Raspailiidae Nardo, 1833 in the order Poecilosclerida, leads to the conclusion that both should be considered congeneric and are best assigned to a single genus Sollasella. This conclusion is based on examination of habit and skeletal characters of the type material of S. digitata and both type and freshly collected material of S. cervicornis. The conclusion is strengthened by the discovery of a new species, Sollasella moretonensis n.sp. collected in North Australia (primarily in the northeastern coast, but also an isolated record from the...

Zoanthids of the Cape Verde Islands and their symbionts: previously unexamined diversity in the Northeastern Atlantic
Provedor de dados: 16
Autores: Reimer, J.D.; Hirose, M.; Wirtz, P.
The marine invertebrate fauna of the Cape Verde Islands contains many endemic species due to their isolated location in the eastern Atlantic, yet research has not been conducted on most taxa here. One such group are the zoanthids or mat anemones, an order of benthic cnidarians (Hexacorallia: Zoantharia) common in many marine environments. In this study, the diversity of zoanthids in the Cape Verde Islands is specifically examined for the first time. Field images and sampling are combined with molecular phylogenetic analyses utilizing two mitochondrial DNA markers (cytochrome oxidase subunit I and 16S ribosomal DNA) to determine the number of species present. Specimens from eight species (Palythoa caribaeorum, Palythoa sp. 265, Zoanthus aff. pulchellus,...

Autores: Vervoort, W.
INTRODUCTION In 1956 Kinne (1956, p. 257) published the description of a new athecate hydroid, Perigonimus megas, discovered by him in the Nordostseekanal, a canal connecting the North Sea with the Baltic. Kinne's new species resembles a well known and widely distributed fresh- and brackish-water hydroid, Cordylophora caspia (Pallas), in fact the resemblance between both species, though belonging to two different families of athecate hydroids (Perigonimus megas to the Bougainvilliidae; Cordylophora caspia to the Clavidae) is such that confusion is likely to occur and Kinne pointed out two occasions where the species have been confused by students of hydroids from the Netherlands. Both cases will be discussed below. The fact that on one of these occasions I...

Autores: Voogd, N.J. de; Cleary, D.F.R.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van.
Sponge assemblages were investigated in the Spermonde Archipelago, southwestern Sulawesi, Indonesia. In this study spatial patterns of sponge similarity among sites were significantly related to remotely sensed environmental variables, the degree of human settlement and depth, but not to the distance between sites. Both oviparous and viviparous species groups responded to similar environmental constraints, and differences in similarity were unrelated to the distance between sites. The degree of human settlement, however, was significantly related to variation in the composition of viviparous, but not oviparous species. Our results demonstrate, most importantly, the utility of remotely sensed data in predicting the spatial turnover of diverse species...

Provedor de dados: 16
Autores: Zibrowius, H.
After introductory remarks on the solitary coral genera Heterocyathus and Heteropsammia, commonly known to be symbiotic with a sipunculan inhabiting a gastropod shell, Heterocyathus japonicus is redescribed in detail. It occurs from Taiwan to northern Honshu, Japan. It is the first of these symbiotic corals to be found in association with an alternative partner, living specimens of the large scaphopod Fissidentalium vernedei. The coral always occupies the apical end of the shell, the part that protrudes from the sediment. It is thus preserved from being buried and is maintained in an upright position (the same advantages it also gets when its partner is a sipunculan). On live F. vernedei, H. japonicus incrusts a manganese rich black mineral coating that...

Autores: Bayer, F.M.
The genus Paragorgia was established by Milne Edwards &amp; Haime in 1857 to receive the large, boreal scleraxonian octocoral from the "Norwegian Ocean", called Alcyonium arboreum by Linnaeus (1758). In subsequent years, that species was reported also from localities in the northern Pacific Ocean (Kinoshita, 1913; Hickson, 1915) and from high southern latitudes off the Falkland Islands (Broch, 1957). In 1883, Koren &amp; Danielssen described two new species from Batalden, Norway, Paragorgia nodosa and Briareum frielei, which generally have been treated as synonyms of P. arborea. Nutting (1908, 1912), however, reported P. nodosa from deep waters off Hawaii and Japan and, furthermore, established a new Japanese species, Paragorgia regalis. Kinoshita (1913)...

A molecularly based phylogeny reconstruction of mushroom corals (Scleractinia: Fungiidae) with taxonomic consequences and evolutionary implications for life history traits
Provedor de dados: 16
Autores: Gittenberger, A.; Reijnen, B.T.; Hoeksema, B.W.
The phylogenetic relationships of the Fungiidae, a family of predominantly free-living, zooxanthellate, reef corals, were studied by sequencing a part of the mitochondrial Cytochrome Oxidase I (COI) and the complete ribosomal Internal Transcribed Spacers (ITS) I &amp; II of specimens from various locations in the Indo- West Pacific. Some sequences were retrieved by using fungiidspecific primers on DNA-extracts from parasitic gastropods living with these corals. The analyses were performed both including and excluding intraspecific variation to investigate the potential effect of saturation. Even though the present molecular phylogeny reconstructions largely reflect those based on morphological characters, there are some distinct differences. Three major...

Autores: Wijsman-Best, M.
Introduction The expedition of H.M. "Willebrord Snellius,, in the eastern Indonesian seas (1929-1930) brought home a large collection of corals. The biologist on board, Dr. H. Boschma, as well as the geologist Dr. Ph. H. Kuenen collected these specimens during low tide on the reefs or by way of dredging and diving. The greater part of the material comes from shallow waters (depths of 0.5 to 5 m). The use of diving apparatus allowed collecting at a depth of 2 to 15 m. Sometimes corals were dredged from depths of 30 m or more. The total coral material consists of more than 10.000 samples, about half of which are specimens of the genus Acropora. Although the material was sorted out and generally identified as to the genus, so far no study was made of any...

Naturally, such data can only be applied with due caution to fossil forms, whose skeletal morphology is often incompletely known. This holds especially true for asteroids, ophiuroids, and crinoids, which, upon death, rapidly disintegrate into jumbles of dissociated ossicles. Bioturbation, scavenging, and current winnowing all contribute to blurring the picture still further. However, data on extant forms do allow a preliminary subdivision of fossil species into various ecological groups, which are...

A new Agelas (Demospongiae: Agelasida: Agelasidae) from the Thousands Islands, West-Java, Indonesia
Provedor de dados: 16
Autores: Voogd, N.J. de; Parra-Velandia, F.J.; Soest, R.W.M. van.
Agelas linnaei spec.nov. (Porifera: Demospongiae: Agelasida: Agelasidae) is described from the Thousands Islands reef complex, West- Java, Indonesia. The new species is compared with all other Agelas species occurring in the Indo-West Pacific region. The new species differs from these other species by the overall morphology and the size of the verticillated acanthostyles. Surprisingly, this is only the second Agelas species ever described from Indonesia.

The identity and occurrence of Kerona pediculus (Ciliophora: Hypotrichida), a well-known epizoite of Hydra vulgaris (Cnidaria: Hydrozoa)
Provedor de dados: 16
Autores: Warren, A.; Robson, E.A.
Epizoic Kerona pediculus have been found on Hydra vulgaris and on Cristatella mucedo (Bryozoa) in the same habitat. On the basis of morphological characters (using Nomarski and Scanning Electron Microscopy) specimens from the two hosts are indistinguishable. Details revealed by SEM agree with previous results from silver staining, confirming the identity of K. pediculus. The taxonomic status of this species is briefly summarised. Host recognition, the inhibition of nematocyst discharge, and the possible role of host growth-promoting substances are not yet understood.

Autores: Voogd, N.J. de.
A new sponge species Callyspongia (Euplacella) biru spec. nov. is described from various locations within Indonesia (NE Bali, SW &amp; NE Sulawesi and NE Kalimantan). The species is assigned to the subgenus Euplacella of the genus Callyspongia because it has brushes of spicules on the nodes of its double-meshed ectosomal skeleton. The species is discussed and compared with relevant Callyspongia records from other Indonesian and neighbouring Indo-Pacific areas.

Fossil and recent shallow water corals from the Atlantic Islands off Western Africa CANCAP-contribution no. 56
Provedor de dados: 16
Autores: Boekschoten, G.J.; Borel Best, M.
Miocene hermatypic corals are listed from Madeira and Porto Santo. Pleistocene and recent shallow water corals are described from the Cape Verde archipelago. The Miocene fauna was part of the Western Tethyan reef association, which went nearly completely extinct by the development of a cool water current in late Miocene times. The Cape Verde fauna immigrated from the Carribean, presumably by way of a compressed subtropical gyre during a mid Pleistocene glacial phase. The fauna was found in a beach terrace, formerly considered Tertiary, on the island of São Tiago. A lava flow directly above this deposit was radiometrically dated 700.000 ± 200.000 years B.P.

Report on a few Octocorals from Eniwetok Atoll, Marshall Islands
Provedor de dados: 16
Autores: Verseveldt, J.
In 1969 Dr. Arthur G. Humes, Boston University, Massachusetts, U.S.A., collected a number of octocorals at Eniwetok Atoll, Marshall Islands. He found that most of these corals were the hosts of copepods, just like the corals collected by him in the waters north-west of Madagascar (vide Verseveldt, 1969: 3). It was with great pleasure that I identified the corals for him. As appears from the survey of the material most of the species are wellknown, with the exception of two species one of which is redescribed below, while the other is described as a new species: Sinularia marenzelleri (Wright &amp; Studer, 1889), this species being insufficiently described by previous authors, and Sinularia brongersmai spec. nov., which is named in honour of Dr. L.

Hydroids from French Polynesia with notes on distribution and ecology
Provedor de dados: 16
Autores: Vervoort, W.; Vasseur, P.
INTRODUCTION  Distribution and ecology of hydroids from coral reefs of high islands and atolls of French Polynesia so far have received little attention. Redier (1967, 1971) published a preliminary list of 14 species from Salvat's collections, sampled during several trips to Tahiti, Tuamoto (Mururoa, Reao and Maturei Vavao Atolls), to the Australes Islands (Rapa) and to Gambier.   The present paper results from researches carried out by one of us (P.V.)  concerning the benthic bionomy of reef sciophilous communities of hard bottoms. They have been carried out at Tiahura, Moorea, Society Islands (fig. IA) and on Takapoto Atoll, Tuamoto Archipelago (fig. 2A) in 1973 and 1974. They gave us occasion to compile a revised list of about 22 species of hydroids...

A centuries old problem in nephtheid taxonomy approached using DNA data (Coelenterata: Alcyonacea)
Provedor de dados: 16
Autores: Ofwegen, L.P. van; Groenenberg, D.S.J.
The current centuries old classification of the family Nephtheidae is still mostly based on colony morphology. In this family the Indo-Pacifc genera Litophyton, Nephthea, Dendronephthya and Stereonephthya, and the Atlantic genus Neospongodes form a complex mix of closely related, poorly described species which cannot be recognized using only colony morphology. Attempts with the more modern approach of comparing skeleton composition (sclerites) have been only partly successful because of the extreme variation of sclerite forms present in these genera. The genus Chromonephthea Van Ofwegen, 2005, introduced for several species previously assigned to Dendronephthya, Nephthea and Stereonephthya, was established with sclerite morphology, but the true generic...

Diversity and spatial heterogeneity of mangrove associated sponges of Curaçao and Aruba
Provedor de dados: 16
Autores: Hunting, E.R.; Soest, R.W.M. van; Geest, H.G. van der; Vos, A.; Debrot, A.O.
Sponges are major epibionts of mangrove roots in the Caribbean. Mangrove sponge communities in the Caribbean mainly consist of species that are typical to this habitat and community compositions often differ from those found on coral reefs nearby. Heterogeneity in species distributions between locations and within locations between roots is often reported. This study quantifies the diversity and abundance of mangrove associated sponges in the inner bays of Curaçao and Aruba and correlates variability of regional sponge diversity with environmental variables measured along the surveyed sites. Tannin concentrations vary between mangrove roots, and were correlated to sponge cover as a possible cause for habitat heterogeneity on a smaller scale. A total of 22...

On the validity of Alcyonium siderium Verrill (Coelenterata : Octocorallia)
Provedor de dados: 16
Autores: Verseveldt, J.
INTRODUCTION Verrill (1879: 199-200) described two specimens of Alcyonium collected on the Fishing Bank, east of Cape Cod, Massachusetts, in 80 fathoms. According to him "they form low, thick, lobular masses", "the base is somewhat spreading" and "the division into rounded or flattened lobes takes place close to the base". He is of opinion that "if not identical with A. digitatum of Europe, it is at least very closely related". More than forty years later Verrill (1922: 20) returns to this question. This time he gives a drawing of one of these American colonies (his textfigure 3), and he has changed his mind regarding the relation to A. digitatum. He now thinks the species is "distinct from the common European species, A. digitatum, to which it is nearly...

Archaeocidaris M’Coy (Echinoidea) from the Carboniferous of Egypt
Provedor de dados: 16
Autores: Lewis, D.N.; Donovan, S.K.
Collections in museums usually have boxes of specimens which remain ‘undiscovered’ and yet which may be of importance or interest. The recent rediscovery of specimens of Archaeocidaris in the Nationaal Natuurhistorisch Museum, Leiden, from the Carboniferous of Egypt illustrates this point. These specimens were collected in 1938 by Dr. H.M.E. Schürmann (1891-1979), who had been a student of Professor J. Wanner (1878-1956), the noted expert on fossil echinoderms. The Egyptian Archaeocidaris plates include interambulacrals and radioles. These are closest to Archaeocidaris rossica (von Buch) from the Moscow area of Russia, although there are sufficient differences in radiole morphology to suggest that they are not necessarily conspecific.

Phylogenetic position and taxonomy of Cycloseris explanulata and C. wellsi (Scleractinia: Fungiidae): lost mushroom corals find their way home
Provedor de dados: 16
Autores: Benzoni, F.; Arrigoni, R.; Stefani, F.; Reijnen, B.T.; Montano, S.; Hoeksema, B.
The scleractinian species Psammocora explanulata and Coscinaraea wellsi were originally classified in the family Siderastreidae, but in a recent morpho-molecular study it appeared that they are more closely related to each other and to the Fungiidae than to any siderastreid taxon. A subsequent morpho-molecular study of the Fungiidae provided new insights regarding the phylogenetic relationships within that family. In the present study existing molecular data sets of both families were analyzed jointly with those of new specimens and sequences of P. explanulata and C. wellsi. The results indicate that both species actually belong to the Cycloseris clade within the family Fungiidae. A reappraisal of their morphologic characters based on museum specimens and...

In this study we assessed the sequence variation in the I3-M11 partition of the mtDNA cytochrome c oxidase subunit I gene (COI) in ten populations of the Atlanto-Mediterranean demosponge Phorbas fictitius (Porifera: Poecilosclerida) at two spatial scales: a regional scale comparing mainland (Iberian) and insular (Macaronesian) populations, and a local (Archipelagic) scale focusing on different island populations of the Azores archipelago. A multiple approach combining diversity measures, FST estimates, phylogenetic inference and nested clade phylogeographic analysis was used to assess the genetic structure and elucidate the evolutionary history of this species. Genetic differentiation, based of FST estimates, was found among most populations at both scales...

In zahlreichen früheren Mitteilungen (2, 4, 5, 7) habe ich bereits auf die Bedeutung der Anomalien in der Ausbildung des Gastrovascularsystems der Rhizostomeen für die Erkenntnis der Phylogenie hingewiesen. Anomalien sind bei den Rhizostomeen nichts seltenes. Oft ist das Gastrovascularsystem nicht in allen Sektoren eines Exemplares gleichmässig entwickelt. Manche zeigen das normale Verhalten, andre eilen in der Entwicklung voraus, andre bleiben dagegen zurück. So kann man gelegentlich bei einem einzigen Exemplar eine ganze Reihe von Entwicklungsstufen des Gastrovascularsystems feststellen, die bei anderen Genera zeitlebens festgehalten werden. Das ist besonders wichtig bei jenen Formen, über deren Ontogenie wenig oder nichts bekannt ist. Gelegentlich der...

Northern Hydroida in the Collections of the Rijksmuseum van Natuurlijke Historie and the Zoological Museum at Amsterdam, with Notes on their Distribution
Provedor de dados: 16
Autores: Vervoort, W.
In the course of 1941 I studied a great number of Hydroida from various northern localities present in the collections of the Zoological Museum at Amsterdam. Most of these collections were made by trawlers from IJmuiden and for the greater part presented to the Museum by Mr. F. P. Vermeulen. They are from localities which are accurately known. Moreover, several samples of Hydroida are present in those collections, which were taken in the neighbourhood of Iceland, either by trawlers from IJmuiden or by Dr. J. Metzelaar and Dr. H. Engel. They were all sent to Dr. P. L. Kramp in 1938, who examined them for his list of Hydroida in "The Zoology of Iceland", vol. 2, pt. 5a. Most of these samples returned identified, but some bottles were returned unnamed from...

Heterochrony, generic distinction and phylogeny in the family Hydractiniidae (Hydrozoa: Cnidaria)
Provedor de dados: 16
Autores: Boero, F.; Bouillon, J.; Piraino, S.
The taxonomy of Hydractinia, Stylactaria and Podocoryna is discussed and the three genera are merged into Hydractinia since their diagnostic characters are liable to lead to polyphyly and paraphyly, due to repeated episodes of medusa reduction via heterochrony (paedomorphosis). The phylogeny of the Hydractiniidae is reconstructed by using two outgroups, Clava and Cytaeis, both having some characters in common with the Hydractiniidae. The resulting phylogenetic trees agree in identifying affinities among Hydractinia, Kinetocodium and Hydrocorella, all with polymorphic colonies with gastrozooids having oral tentacles. The position of Clavactinia (characterized by gastrozooids with widely scattered tentacles) is at the root of the tree if Clava is the...

Octocorallia from North-Western Madagascar (Part I)
Provedor de dados: 16
Autores: Verseveldt, J.
INTRODUCTION During the years 1960, 1963, 1964 and 1967 Dr. Arthur G. Humes, Boston University, Massachusetts, U.S.A., collected a number of octocorals in the waters north-west of Madagascar, near the islands Nosy Bé, Nosy Komba, Ambariobe (a small island nearly between Nosy Komba and Nosy Bé), Tany Kely (a small island to the south of Nosy Bé), Nosy Faly, Isles Mitsio, etc. The purpose of his collecting was the study of the copepods associated with these corals. In order to know the identity of the coral hosts of his copepods, Dr. Humes entrusted his extensive collection to me for identification. I wish to express my best thanks to Dr. Humes for giving me the opportunity of working on his interesting material. The present paper forms the first of a series...

Taxonomy and phylogenetic relationships of the coral genera Australomussa and Parascolymia (Scleractinia, Lobophylliidae)
Provedor de dados: 16
Autores: Arrigoni, R.; Richards, Z.T.; Chen, C.A.; Baird, A.H.; Benzoni, F.
Novel micromorphological characters in combination with molecular studies have led to an extensive revision of the taxonomy and systematics of scleractinian corals. In the present work, we investigate the macro- and micromorphology and the phylogenetic position of the genera Australomussa and Parascolymia, two monotypic genera ascribed to the family Lobophylliidae. The molecular phylogeny of both genera was addressed using three markers, the partial mitochondrial COI gene and the nuclear histone H3 and the ribosomal ITS region. Based on molecular data, Australomussa and Parascolymia belong to the Lobophylliidae and they cluster together with the genera Lobophyllia and Symphyllia within the same clade. While A. rowleyensis and P. vitiensis are closely...

Late Cretaceous bourgueticrinid crinoids from southern Poland – preliminary observations
Provedor de dados: 16
Autores: Jagt, J.W.M.; Salamon, M.A.
Dissociated skeletal elements of bourgueticrinid crinoids, comprising mostly columnals, radicular cirri, a few cups and some brachials, are recorded from Turonian-Maastrichtian strata of southern Poland (Miechów Trough, Kraków-Cze˛stochowa Upland, Holy Cross Mountains and Opole Trough). Published records of bourgueticrinids from Poland are surprisingly few; only specifically indeterminate columnals, radicular cirri and a sole proximale, plus a single cup of Bourgueticrinus utriculatus have been noted. The present material, although limited, clearly demonstrates that these crinoids must have been less rare than anticipated and are, in fact, distributed throughout the entire Upper Cretaceous sequence in this area. The majority of bourgueticrinids had an...

The role of Spain in the development of the reef Brachiopod faunas during the Carboniferous
Provedor de dados: 16
Autores: Winkler Prins, C.P.
After a short introduction on the reef development during the Late Palaeozoic, the tectono-stratigraphic history of the Cantabrian Mountains (northern Spain) during the Carboniferous is discussed, with an emphasis on the tectonically active Pennsylvanian (i.e., Late Carboniferous). The reef-bearing Valdeteja, San Emiliano, and Cuera formations are briefly described, and their brachiopod faunas are discussed with special emphasis on adaptations to a reef environment. The brachiopod faunas are compared with similar faunas from carbonate-platform deposits with reef structures of Mississippian (i.e., Early Carboniferous) age from Northwest Europe (the British Isles in particular), with Pennsylvanian-Permian faunas from the Alps, Urals, Spitsbergen and Arctic...

Provedor de dados: 16
Autores: Taylor, P.D.; McKinney, F.K.
The Late Cretaceous bryozoan fauna of North America has been severely neglected in the past. In this preliminary study based on museum material and a limited amount of fieldwork, we describe a total of 128 Campanian-Maastrichtian bryozoan species from Delaware, New Jersey, North Carolina, South Carolina, Tennessee, Georgia, Alabama, Mississippi, Louisiana and Arkansas. Eighty-two of these species are new, as are five (Basslerinella, Pseudoallantopora, Kristerina, Turnerella and Peedeesella) of the 77 genera. One new family, Peedeesellidae, is proposed. Cheilostomes, with 94 species (73 per cent of the total), outnumber cyclostomes, with 34 species (27 percent), a pattern matching that seen elsewhere in the world in coeval deposits. There appear to be very...

A monograph of the freshwater Bryozoa-Phylactolaemata
Provedor de dados: 16
Autores: Lacourt, A.W.
1. This paper presents the taxonomy of the Bryozoa Phylactolaemata. The group is found to contain a number of series. The present classification reveals that a number of specific names are synonyms. 2. The evolution of the group is described on the basis of the development of the zoarium and the species-specific statoblasts. 3. The Phylactolaemata are to be considered as a group that have completed their evolution with the development of giant species with giant and specialized forms of statoblasts; this has been accompanied by a reduction in the number of tentacles. 4. The distribution of the species was assessed from the available data. The main concentration is found to occur in the southern hemisphere. 5. The distribution supports the conclusion that...

Gattya wimleni spec. nov. (Cnidaria: Hydrozoa), a new hydroid from Madagascar, and an identification key to the Gattya species
Provedor de dados: 16
Autores: Gravier-Bonnet, N.
Gattya wimleni spec. nov. is referred to the family Halopterididae (Hydroida, Thecatae). Colonies were collected at Tuléar (SW Madagascar, Indian Ocean) on the deeper part of the lower sloping platform, at 35 to 45 metres depth on the outer slope of the great barrier reef. The specimens were studied in transmitted light and by SEM. They differed from the eight species of Gattya already known in having a hydrothecal margin provided with four large rounded teeth of equal size - one abcauline, one adcauline and two lateral, curving inwards over the aperture, the laterals being hidden behind the lateral nematothecae in profile view. Its closest affinities are with the species G. multithecata (Jarvis, 1922) and G. aglaopheniaformis (Mulder &amp; Trebilcock,...

INTRODUCTION Mr. Austin Hobart Clark, a personal friend of Dr. H. Boschma and during many years curator of the collections of Echinoderms in the U.S. National Museum (Smithsonian Institution), died on October 28, 1954, before his study of the collection of Ophiuroidea from the Snellius Expedition could be completed. A large part of this collection, identified by Mr. Clark, is now preserved in the Rijksmuseum van Natuurlijke Historie, Leiden; a minor portion of the Ophiurid collection still awaits its revisor. Amongst the identified material there are two new species, the descriptions and drawings of which were finished by Mr. Clark before his decease.

Boring sponges (Porifera, Clionidae) collected during the "Tydeman" Canary Islands expedition Cancap-II, 1977
Provedor de dados: 16
Autores: Groot, R.A. de.
INTRODUCTION AND MATERIAL The boring sponges of the Canary Islands have never been studied in any detail, but the boring fauna of this archipelago cannot be expected to be very rich. All islands are volcanic and calcareous rocks are not common. Consequently, in most areas large shells and rhodophyte incrustations are the only substrata available for boring sponges. Moreover, the islands are truly oceanic. Eggs or larvae (according to Trégouboff, 1957, clionids are oviparous) have to cross a distance of at least 90 km to reach the Canary Islands from the African coast, where calcareous substrata are abundant. Because of the isolated position of the islands endemism may be expected. All material was obtained during the second expedition of the CANCAPproject...

Nomenclator Actinologicus seu Indices Ptychodactiariarum, Corallimorphariarum et Actiniarianum comprising indexes of the taxa, synonyms, authors and geographical distributions of the sea anemones of the world included in Professor Oskar Carlgren's 1949 survey
Provedor de dados: 16
Autores: Williams, R.B.
In 1949, the late Professor Oskar Carlgren of Lund, Sweden, published a bibliographical survey of the sea anemones of the world, comprising 42 families, 201 genera and 848 species. The survey is an essential starting point for any taxonomic or zoogeographical work on sea anemones. However, the enormous wealth of information that it contains is difficult to extract, because of the lack of adequate indexation. Indexes have therefore been prepared to increase the usefulness of the survey. They are: I, Nomenclatural; II, Authors; III, Geographical. Two appendixes give details of new nominal taxa and nomina nuda published in the survey. No attempt has been made to correct or revise the results of Carlgren's survey: the objective is solely to facilitate the...

Die Scyphomedusen-Sammlung des naturhistorischen Reichsmuseums in Leiden : I. Die Carybdeiden (Cubomedusen)
Provedor de dados: 16
Autores: Stiasny, G.
EINLEITUNG. Die in der vorliegenden Mitteilung besprochenen Cubomedusen bilden einen kleinen gut abgegrenzten Teil der grossen Scyphomedusen-Sammlung des Rijksmuseums van Natuurlijke Historie in Leiden, über welche zu einem späteren Zeitpunkte ausführlich berichtet werden wird. Von diesen aberranten und seltenen Formen liegt eine relativ ganz ansehnliche Anzahl (25 Exemplare) vor, die verschiedenen Genera und vielleicht auch verschiedenen Species angehören. Bei der Seltenheit dieser Medusen ist dies reichhaltig zu nennen. Zum grossen Teil stammen sie aus dem malayischen Archipel, doch liegen auch Formen aus dem Mittelmeer und West-Indien vor. Die meisten Stücke wurden von dem Schiffsarzt P. Buitendijk, der jahrelang im Archipel gereist ist, gesammelt, 1...

Ueber einige Scyphomedusen von Sydney (Port Jackson)
Provedor de dados: 16
Autores: Stiasny, G.
Zur Bearbeitung liegen folgende australische Medusen vor: Phyllorhiza punctata von Lendenfeld. Catostylus mosaicus L. Agassiz (= Crambessa mosaica von Lendenfeld). Aurelia coerulea von Lendenfeld. Obwohl diese kleine aus 54 Exemplaren bestehende Sammlung von Scyphomedusen aus Port Jackson nur 3 verschiedene bereits bekannte species umfasst, ist sie doch von Interesse, da diese Medusen seit R. v. Lendenfeld in den Jahren 1884/8 durch keinen Forscher nachuntersucht worden sind. Trotzdem seine von vielen schönen Abbildungen begleitete Beschreibung der australischen Rhizostomeen sehr ausführlich ist (9), hat sich gezeigt, dass dieselbe in manchen Punkten unklar oder unzureichend ist. So konnte z. B. bei Phyllorhiza punctata weder Claus (2), noch Vanhöffen...

Affinities of the family Sollasellidae (Porifera, Demospongiae). II. Molecular evidence
Provedor de dados: 16
Autores: Erpenbeck, D.; Hooper, J.N.A.; List-Armitage, S.E.; Degnan, B.M.; Wörheide, G.; Soest, R.W.M. van.
This is the second part of a revision and re-classification of the demosponge family Sollasellidae, and an example of a successful use of combined morphological and molecular data. Sollasella had been a poorly known, long forgotten taxon, placed incertae sedis in the order Hadromerida in the last major revision of the demosponges. It has recently been suggested to belong to Raspailiidae in the order Poecilosclerida due to striking morphological similarities. The present analysis verified this re-classification using molecular markers. Comparing 28S rDNA fragments of Sollasella cervicornis, a newly described species S. moretonensis and a representative set of raspailiid and hadromerid samples. In our analyses Sollasella clearly clusters inside the...

Masquerade, mimicry and crypsis of the polymorphic sea anemone Phyllodiscus semoni and its aggregations in South Sulawesi
Provedor de dados: 16
Autores: Hoeksema, B.; Crowther, A.L.
Phyllodiscus semoni is a morphologically variable sea anemone species from the Indo-Pacific with morphotypes ranging from upright and branched to low-lying and rounded. The apparent camouflage strategies of this sea anemone allow it to resemble other species or objects in its environment, such as stony corals, soft corals, seaweeds, or rocky boulders covered by algae, which may help it to avoid recognition by potential predators. Occasionally, it occurs in aggregations that may result from asexual reproduction. A high level of intraspecific morphological variation, including co-occurring aggregations of three different morphotypes, was observed in the Spermonde Archipelago off Makassar, South Sulawesi, Indonesia. The co-occurrence of aggregations with...

Redescription of Oswaldella antarctica (Jäderholm, 1904) (Cnidaria Hydrozoa) with notes on related species (Notes on Antarctic hydroids, I)
Provedor de dados: 16
Autores: Peña Cantero, A.L.; Vervoort, W.
Jäderholm's type of Schizotricha antarctica, collected by the Swedish Antarctic Expedition 1901-1903, is redescribed from a syntype in the collections of the Swedish National Museum, Stockholm. The type lot of that species proved to be composite, the material best resembling Jäderholm's (1904, 1905) descriptions and figures has been designated as the syntype. There are two more species in the type lot, that have also been described, but are too poorly represented to be either recognized as one of the described species of Oswaldella or to merit a new specific name; they have been indicated as Oswaldella spec. 1 and spec. 2.

Autores: Schuchert, P.
All genera and species of the hydrozoan family Halopterididae are reviewed. Where material was available, species are described and figured and the extent of morphological variation is assessed as far as possible. The re-examined material includes samples from the Challenger, Siboga, and Galathea expeditions. Numerous types were re-examined and taxonomic revisions made where necessary. For several nominal species lectotypes are designated. Two new species are described: Antennella kiwiana from New Zealand and Halopteris platygonotheca, a wide spread species from the Indo-Pacific Ocean. Halopteris buskii var. peculiaris (Billard, 1913) is raised to species level as Halopteris peculiaris. Several species are sunk into synonymy: Plumularia balei Billard, 1911...

Provedor de dados: 16
Autores: Boero, F.; Bouillon, J.; Kubota, S.
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...

Linckia rosenbergi Von Martens, a Synonym of L. laevigata (L.)
Provedor de dados: 16
Autores: Engel, H.
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. &amp; Troschel), aber die Poren behalten dieselbe Anordnung in runde Gruppen (Felder) von circa 10 Poren bei".

Towards a systematic standard approach to describing fossil crinoids, illustrated by the redescription of a Scottish Silurian Pisocrinus de Koninck
Provedor de dados: 16
Autores: Fearnhead, F.E.
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.

Nineteen species of Alcyoniidae formerly assigned to various genera are here placed in the genera Bellonella and Eleutherobia; three new species are described in Bellonella. Sixteen species characterized by an abundance of capstans among their sclerites, formerly assigned to Alcyonium, Bellonella and Nidalia are now transferred as valid species or synonyms to the genus Eleutherobia, in which two new species are described making a total of 14 valid species. A new genus Inflatocalyx is established for a digitiform subantarctic species having only very few sclerites, in the form of nearly smooth spindles, and polyps retractile within large, inflated calyces. Six species comprising the genus Cactogorgia are transferred to Nidalia, and three new species are...

Autores: Calder, D.R.; Maÿal, E.M.
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...

On two different growth-forms of Merulina laxa, Dana
Provedor de dados: 16
Autores: Boschma, H.
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 &amp; 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.
