| 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... |

| Twenty-seven species of holothurian are recorded from the East Indies, including a new species in the synaptid genus Protankyra collected from the central north coast of Java. The majority of the species are widely distributed throughout the Indo-west Pacific region. However, Labidoplax incerta (Ludwig, 1875), known only from Java, is recorded for the second time from the same area. |

| 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... |

| 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... |

| 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... |

| Among the Fungid corals, which Dr. van Oort, the director of the Leyden Museum, has put at my disposal to examine, for which I feel extremely grateful, there were two specimens, which differ so much from all previously recorded forms, that I have no hesitation in describing them as a new species. Fungia moluccensis nov. spec. Corallum oval in shape, heavy; wall with a few slits near the periphery, otherwise solid, aboral surface concave. Margin of the corallum rounded. Upper surface much arched round the axial fossa, at the edge equally thick. Central area of the under surface densely granulated. Ribs only distinct at the periphery, unequal. The larger ones extend farther to the centrum; in the central area they continue for some distance like rows of... |

| The genus Paragorgia was established by Milne Edwards & 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 & 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)... |

| In this paper we describe Suberites diversicolor spec. nov. (Porifera: Demospongiae: Hadromerida: Suberitidae) from four enclosed anchialine lakes located in Indonesia and from a confined system in Singapore. 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. Suberites diversicolor spec. nov. differs from known... |
