A history of the British marine Polyzoa

Abstract: THE value to science of Mr. Van Voorst's splendid series of volumes descriptive of the Natural History of the British Islands is scarcely to be overrated. The monographs are all the work of most eminent naturalists, in whom perfect confidence may be placed, and they are sumptuously printed and illustrated with abundance of excellent plates and woodcuts. The thanks of naturalists generally are certainly due to Mr. Van Voorst. The present work is fully equal in merit to its predecessors; it consists of two volumes—one of 600 pages of text, the other containing eighty-three lithographic plates. Mr. Hincks, whose industry is indefatigable, has already contributed to Mr. Van Voorst's series the well-known excellent monograph on the Hydroid Zoophytes. The labour involved in the production of a monograph such as that now under consideration is very great. All the 235 species occurring on the British coast are figured, with one or two exceptions in cases where specimens do not exist for the purpose. All the figures have been drawn by the author himself and beautifully lithographed by Mr. Hollick. Further figures are added taken from various monographs where such are necessary for the elucidation of the subject.A History of the British Marine Polyzoa.By Thomas Hincks (London: J.

Systematics and ecology of the Isefjord marine fauna (Denmark) with a survey of the eelgrass (Zostera) vegetation and its communities

Abstract: This paper represents the results of more than 30 years field observations and research work carried out from the Isefjord Laboratory, Vellerup Vig (Zealand, Denmark), which is owned and financed by the author. The Isefjord complex, 36 km long, including the main fjord and the Roskilde Fjord, and covering about 400 km2, is a shallow (7–10 m, max. 30 m) area dominated by substrata of fine sand to mud with a high content of organic matter. As a guidebook for future research the first part gives information about distribution, systematics, ecology, and breeding of the majority of the 477 animal species described. Nearly 400 species are invertebrates and of the chordates 68 species are true fishes. 63% of all animal species have not previously been recorded from the area, 27 species are new to Danish seas, and one (Polychaeta, Capitellidae) is new to science. The hydrography is treated mainly on the basis of literature. The fjord system may be classified as mixohaline: the Isefjord proper is polyhali...

Introduced and cryptogenic species in Port Phillip Bay, Victoria, Australia

Abstract: Port Phillip Bay (PPB) is a large (1,930 km2), temperate embayment in southern Victoria, Australia. Extensive bay-wide surveys of PPB have occurred since 1840. In 1995/1996 the Commonwealth Scientific and Industrial Research Organization (CSIRO) Centre for Research on Introduced Marine Pests (CRIMP) undertook an intensive evaluation of the region with the aims of developing a comprehensive species list of native and introduced biota and contrasting previous bay-wide assessments with a current field survey in order to detect new incursions and discern alterations to native communities. Two methods were used to meet these aims: a re-evaluation of regional museum collections and published research in PPB to identify and determine the timing of introductions; and field surveys for benthic (infauna, epifauna and encrusting) organisms between September 1995 to March 1996. One hundred and sixty introduced (99) and cryptogenic (61) species were identified representing over 13% of the recorded species of PPB. As expected, the majority of these are concentrated around the shipping ports of Geelong and Melbourne. Invasions within PPB appear to be increasing, possibly due to an increase in modern shipping traffic and an increase in aquaculture (historically associated with incidental introductions); however the records of extensive biological surveys suggest that this may, in part, be an artefact of sampling effort. In contrast to Northern Hemisphere studies, PPB (and Southern Hemisphere introductions in general) have significantly different suites of successfully invading taxa. PPB is presented as one of the most invaded marine ecosystems in the Southern Hemisphere.

The European athecate hydroids and their medusae (Hydrozoa, Cnidaria): Capitata Part 1

Abstract: The European athecate hydroids and their medusae (Hydrozoa, Cnidaria): Filifera Part 4. - This study reviews all European hydroids belonging to the filiferan family Eudendriidae. Two new species occurring in the northeastern Atlantic are described: Eudendrium capillaroides new spec. and Eudendrium unispirum new spec. Eudendrium vaginatum Allman, 1863, is redescribed. It is characterized by a special type of nematocysts and traits of the perisarc. It is distinct from Eudendrium annulatum Norman, 1864, which is a separate, valid species. Eudendrium fragile Motz- Kossowska, 1905 and Eudendrium islandicum Schuchert, 2000 are both recognized as synonyms of E. album Nutting, 1898. Eudendrium stratum Bonnevie, 1898 and E. planum Bonnevie, 1898 are both recognized as synonyms of E. rameum (Pallas, 1766). Eudendrium insigne Hincks, 1861 is indistinguishable from E. ramosum and newly collected material from the type locality confirmed this. Eudendrium insigne must thus be regarded as a synonym of E. ramosum (Linnaeus, 1758). A re-examination of the type material of Eudendrium elsaeoswaldae Stechow, 1921 revealed that it is conspecific with E. ramosum (Linnaeus, 1758), becoming thus a new synonym of the latter. Perigonimus multicornis Allman, 1876 is indistinguishable from Myrio - nema hargitti (Congdon, 1906) and must be regarded as a senior synonym of the latter. Because it seems likely that the original type locality designation "Kattegat" was incorrect, it should not replace M. hargitti or M. amboinense.
