| During an expedition with scuba-divers to the Dutch part of the Brown Ridge in the central North Sea in June 2013, two colonies of the jewel anemone Corynactis viridis were found on the wreck Anna Graebe. With the jewel anemone both a new species and a new animal order, the Corallimorpharia, are added to the autochthonous fauna of the Netherlands. This species typically occurs in the Mediterranean and along the Atlantic coast from Portugal and the west British Isles up to Shetland. As other records of settled colonies of C. viridis in the North Sea were recently reported from Belgian, German and English waters, it is concluded that the jewel anemone, which used to be known as an occasional visitor, should now be considered autochthonous in the North Sea. |

| 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,... |

| An account is given of some hydroids from the Mid-Atlantic Ridge, collected during dives of submersibles "Nautile" (operated by IFREMER, France) and "Alvin" (operated by Woods Hole Oceanographic Institution, U.S.A). The specimens came from three main sectors of the ridge: 15 species from localities near hydrothermal fields (540-1727 m) SW of the Azores, five species from an area (2565-3902 m) west of the Cape Verde Islands near Researcher Ridge, and one species from a site (4529-4578 m) within the Vema Fracture zone west of Guinea Bissau. In all, 21 species were distinguished, comprising two anthoathecates and 19 leptothecates. The families Lafoeidae and Sertulariidae were best represented, with six and four species respectively. Halecium profundum spec.... |

| Representatives of three species of Bouillonia Petersen, 1990 are studied and described: syntype specimens of Bouillonia cornucopia Bonnevie (1898), from the Zoological Museum, University of Oslo; a putative new species from the Arctic (“Polarstern”, 1995); and Bouillonia denhartogi spec. nov. from the Antarctic: Weddell Sea (“Polarstern”, 2000, 2005), Antarctic Peninsula (“Lawrence M. Gould”, 2002, 2003), S. Sandwich Is. (“Nathaniel B. Palmer”, 2004), and the Ross Sea, (“Nathaniel B. Palmer”, 2005). Characters given by Petersen for the genus are discussed and a new, wider description of Bouillonia is proposed. Questions concerning the bipolar distribution of this genus are also discussed. |

| Fourty-four species and one variety of hydroids were identified in the John Murray hydroid collection, obtained from the Gulf of Aden, the Arabian Sea and the northern part of the Indian Ocean, largely from deep water localities. Of these 44 species 2 could be identified only to genus, 1 species is doubtfully mentioned and 5 are new to science. The 44 species we assigned to 2 families of athecate and 6 families of thecate hydroids. In many instances the species have been compared with the type material which, where necessary, was redescribed. A number of additional species, not represented in the John Murray collection has also been redescribed and/or figured. Practically all the John Murray hydroids are figured. Deposition of spirit-preserved type and... |

| Lohowia koosi, a new species and new genus in the family Alcyoniidae, is described from Lord Howe Island, Australia. The new taxon has dimorphic polyps and a similar morphology to some of the flat, lobe-less nominal species of Lobophytum. The new taxon is clearly distinguished, however, by the possession of large, heavily armed autozooids, polypary surface sclerites in the form of large spindles that protrude through the surface, extremely large interior sclerites and base surface sclerites in the form of rods, spindles and ovals. |

| 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 & Trebilcock,... |

| A new family of antipatharian corals, Myriopathidae (Cnidaria: Anthozoa: Antipatharia), is established for Antipathes myriophylla Pallas and related species. The family is characterized by polyps 0.5 to 1.0 mm in transverse diameter; short tentacles with a rounded tip; acute, conical to blade-like spines up to 0.3 mm tall on the smallest branchlets or pinnules; and cylindrical, simple, forked or antler-like spines on the larger branches and stem. Genera are differentiated on the basis of morphological features of the corallum. Myriopathes gen. nov., type species Antipathes myriophylla Pallas, has two rows of primary pinnules, and uniserially arranged secondary pinnules. Tanacetipathes Opresko, type species T. tanacetum (Pourtalès), has bottle-brush... |

| 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... |
