| 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. |

| Species of Corallimorpharia collected during the CANCAP expeditions in the south-eastern part of the North Atlantic are described and discussed, altogether five species belonging to three genera of Corallimorphidae: the shallow water forms Corynactis viridis Allman, 1846, Pseudocorynactis caribbeorum den Hartog, 1980, and P. caboverdensis spec. nov., and the deep-sea forms Corallimorphus cf. atlanticus Carlgren, 1934, and C. ingens Gravier, 1918. The taxonomic status of the representatives of the genus Corynactis Allman, 1846, is discussed. All temperate to subtropical species described so far belong to a group of closely related allopatric taxa forming the Corynactis viridis-complex, possibly representing a single species only. The colours of Corynactis... |

| Since the study of the genus Corallimorphus was started, the main taxonomic character used to separate species has been the ratio of the number of marginal tentacles to that of the discal ones. Polyps with a marginal:discal (m:d) tentacle ratio of 2:1 and 4:1 collected by the “Challenger” expedition were described as two distinct species, Corallimorphus rigidus and Corallimorphus profundus respectively (Moseley, 1877a, 1877b; Hertwig, 1882, 1888). This feature remained important in the taxonomy of the genus. For example, Fautin et al. (2002) subdivided the genus Corallimorphus into two groups of species: Corallimorphus rigidus, C. ingens, C. atlanticus, C. denhartogi (ratio of marginal: discal tentacles 2:1) were referred to the «rigidus» group. C.... |

| 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... |
