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.

INTRODUCTION The present report deals with a collection of Hydroids from the Zoological Museum, Munich, German Federal Republic (Zoologische Sammlung des Bayerischen Staates, München), collected during various expeditions in the Caribbean region. I have thought it advisable to include in this report an annotated checklist of all Hydroids that in the course of time have been recorded from the Caribbean region. The geographical boundaries of that region are discussed below. I want to express my sincere gratitude to Dr. W. Engelhardt and Dr. H. Fechter of the Zoological Museum, Munich, who have placed the valuable material at my disposal. All the material is now preserved in the Zoological Museum, Munich; some duplicates are present in the collections of the...

A description is given of a corymorphid polyp, Corymorpha tomoensis Ikeda, 1910, collected during an expedition of the National Museum of Natural History, Leiden, The Netherlands, to the Indonesian island of Ambon. This is the first record of a polyp of the genus Corymorpha M. Sars, 1835 from Indonesian waters; corymorphid medusae were collected during the Siboga Expedition and described by Maas (1905) as Euphysora bigelowi; the polyp of that species was subsequently reared in the laboratory (Sassaman & Rees, 1978) and identified as a species of Corymorpha. Species now classified in Corymorpha M. Sars, 1835 are briefly reviewed and their status and distribution discussed.

The type series of Schizotricha anderssoni Jäderhoim, 1904, collected by the Swedish Antarctic Expedition 1901-1903 and deposited in the collections of the Swedisch National Museum, Stockholm, is redescribed. The type series is composed of two species, the species figured by Jäderhoim (1905) is designated the lectotype of Schizotricha anderssoni. The second species, differing from the other species of the genus, is described as Schizotricha jaederholmi spec. nov.

Species of the genus Sertularella from the coasts of Galicia (Atlantic coast of Spain) have been studied and 5 species, S. gayi (Lamouroux, 1821), S. polyzonias (Linnaeus, 1758), S. ellisii (Deshayes & MilneEdwards, 1836), S. fusiformis (Hincks, 1861), and S. mediterranea Hartlaub, 1901, are recognized, described, and their synonymy discussed. Notes are added on two species of which the names occur repeatedly in European hydroid literature but that in our opinion belong in the southern Atlantic fauna: S. gaudichaudi (Lamouroux, 1824) and S. picta (Meyen, 1834).

Report on the Haleciidae and Plumularioidea (Cnidaria, Hydrozoa) collected by the French SEAMOUNT 1 expedition

Ramil, F.; Vervoort, W.; Ansín, J.A..

The study of a part of the material collected by the French oceanographic expedition "SEAMOUNT 1" made it possible to identify 21 species and one subspecies of hydroids of the families Haleciidae (4 species), Aglaopheniidae (7 species), Halopterididae (3 species), Kirchenpaueriidae (2 species and one subspecies) and Plumulariidae (5 species). Of these species, 10 have an Atlantic-Mediterranean distribution, 6 are cosmopolites, 4 are known from the north-eastern Atlantic, near to the area studied, and only one, Pseudoplumaria sabinae Ramil & Vervoort, 1992, is momentarily only known from Gorringe and Ampere Banks.

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 & Stout, 1969). The bulk of the material on...

Twenty-eight hydroid species are recorded from the eastern Mediterranean and the northern part of the Red Sea, all material originating from the collections of the Museum of the Zoological Institute, Tel-Aviv University. The collection also included four species that could only be identified to generic level. Though the majority had previously been recorded from either the Mediterranean or the Red Sea, some constitute the first definite record from Israeli coastal waters. All material has been redeposited in the Tel-Aviv collection; slides and some duplicate samples are in the collections of the National Museum of Natural History (Nationaal Natuurhistorisch Museum, now also incorporating the Rijksmuseum van Natuurlijke Historie), Leiden, the Netherlands.

Forty leptolid species are described from the north-eastern Atlantic (Macaronesian area and the coasts of Mauritania and Morocco) and additional data are given for 44 leptolids described in previous reports. Two new species of Hydractinia and one new species of Zygophylax are described. Zygophylax echinata Calder & Vervoort, 1998 has been synonymized with Zygophylax sagamiensis Hirohito, 1983. The geographical boundaries of several species have been extended amongst which some (Hydractinia multitentaculata Millard, 1975; Hydractinia marsupialia Millard, 1975, Hydrocorella africana Stechow, 1921) that were hitherto considered to be endemic to South African oceanic waters. Halecium sessile Norman, 1867, turned up in the CANCAP collections after the...

The material assigned by Totton (1930) to Oswaldella antarctica (Jaderholm, 1904) and O. bifurca (Hartlaub, 1904) has been re-examined and redescribed. This material shows such important differences with Hartlaub's and Jäderholm's species and the remaining species of Oswaldella that they are here considered as two new species: O. terranovae spec. nov. and O. tottoni spec, nov., respectively.

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...

Gustav Albert Stiasny

Gustav Albert Stiasny was born in Vienna (Austria) on December 10th, 1877. After he had attended the elementary and grammar schools there and having finished a one year course of lectures in commercial enterprise, Stiasny enlisted as a volunteer with the Austro-Hungarian army. A year later he left the army after he had obtained his commission, to take up an appointment with his father's commercial business. Young Stiasny, who was much interested in Natural History, soon left his father's affairs to give himself completely to the study of Zoology, Botany and Geology. For that purpose he attended lectures at the universities of Vienna and Jena. As about that time such celebrities as Hatschek, Grobben, Haeckel, et al., were lecturing there it is no wonder...

The morphology of 25 species of the family Eudendriidae was studied, with special regard to their reproductive organs, using techniques of SEM and optical microscopy. Whenever possible a re-analysis of the diagnostic characters of these species was carried out. Furthermore, several synonymies were confirmed or discussed and remarks on taxonomical details are presented. A developmental (ontogenetical) series is proposed for the reproductive differentiation, and its usefulness for phylogenetic analysis is considered.

Seventy seamounts 50 to 100 km off South East Cape, southern Tasmania, rise from depths of 1000- 2000 m on the Australian continental slope. Sampling of the slopes of 14 seamounts was undertaken in 1997 by the Australian Commonwealth Scientific & Industrial Research Organisation (CSIRO). The collection yielded 14 species of hydroids, six of which are new, including two species of a new genus. Only Halecium fragile Hodgson, 1950, and Tripoma arboreum Hirohito, 1995, have previously been recorded from Tasmania. Other species are known from deep water off New Zealand, Japan and the south-western Atlantic.

In the course of 1944, whilst engaged with the revision of the collections of Hydroids in the Rijksmuseum van Natuurlijke Historie at Leiden and the Zoological Museum at Amsterdam, I had the opportunity to study a considerable number of Hydroids from the tropical and subtropical parts of the three large oceans. No report has up to the present time been published on these Hydroids, although many specimens are of considerable interest. The present paper contains the results of the study of these samples, which were kindly put at my disposal by Prof. Dr. H. Boschma and Prof. Dr. L. F. de Beaufort. I also wish the express my sincere thanks to Mrs. W. S. S. van der Feen née van Benthem Jutting and Miss Dr. Jos. Th. Koster for their assistance in providing me...
