    Description: A faunistic study of the family Haleciidae from the Strait of Gibraltar and nearby areas has been made; seven species are described, figured and discussed. Information about the zoogeographical distribution, and conditions of substrates are contributed. A key to distinguish the species of this family from the seas of the Iberian Peninsula is presented, and the Iberian Haleciidae are compared with those from the Mediterranean and the British Isles.

    Description: 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 publication of the report on Haleciidae from CANCAP (Medel & Vervoort, 2000) and is described here. All material described in the present report is preserved in the collections of the National Museum of Natural History Naturalis, Leiden, the Netherlands; the collection numbers of the samples and those of the microslide preparations are given in the text.

    Description: A new species of the leptolid family Plumulariidae, Nemertesia tropica spec. nov. is described. The various species of Nemertesia are listed and their synonymy and characters discussed. Allocation in Nemertesia of some species previously described in Plumularia by Fraser (1938-1948) necessitated the introduction of two new names, viz. Nemertesia californica nom. nov. for Plumularia mutabilis Fraser, 1948 and Nemertesia mexicana nom. nov. for Plumularia reversa Fraser, 1938.

    Description: After studying the type specimens we conclude that the species Eudendrium vestitum Allman, 1888, is a junior synonym of the cosmopolitan bougainvilliid Bimeria vestita Wright, 1859. A redescription accompanied by optical micro- and SEM photographs of the species is presented.

    Description: 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.

    Description: In this paper a review is presented of the Dutch leptolid (= hydroid) fauna (phylum Cnidaria, class Leptolida). The Dutch faunal boundary has been defined by Boschma (1927) and was based on the presence of lightvessels off the Dutch shores. Though the lightvessels have\ndisappeared this formal faunal boundary has been maintained. A total of 146 species, belonging to 87 genera in 38 families, are shortly described and illustrated. 114 species can be considered truly indigenous Dutch species, of which the occurrence within the Dutch faunal boundaries is substantiated by material in collections or records in the faunistic literature. Of seven species either material or convincing records are available but their geographical distribution indicates that they do not form part of the Dutch fauna, whereas of 25 species the distributional pattern indicates that sooner or later they will be may become part of the Dutch fauna.

    Description: A bibliography is presented of works on non-siphonophoran hydroids (Leptolida) published since 1910, the preceding period being covered by M. Bedot\'s "Mat\xc3\xa9riaux pour servir \xc3\xa1 l\'histoire des Hydro\xc3\xafdes". As the scope of the present taxon (Leptolida) is wider than that studied by Bedot an additional list of Leptolid papers is also given, including a few papers that escaped Bedot\'s attention.

    Description: Twenty-one (sub)species of Leptolida (Hydrozoa, Cnidaria) of the familes Haleciidae and Campanulariidae are described and figured, originating from collections made during the CANCAP and Mauritania- II expeditions of the Rijksmuseum van Natuurlijke Historie (now Nationaal Natuurhistorisch Museum) to the north-eastern Atlantic in the years 1976-1988, visiting waters around the Azores, Canary Islands, Madeira, Cape Verde Islands and off Morocco and Mauritania. This material largely concerns well known species, the majority of which needs no detailed description. Exceptions are i.a. Halecium liouvillei Billard, 1934, Halecium sibogae marocanum Billard, 1934, Clytia arborescens Pictet, 1893, and Laomedea pseudodichotoma Vervoort, 1959. These species are described in more detail as their distributional area is extended. Of all species extensive literature references are given and the geographical distribution is discussed in detail.

    Description: Five species of the genus Schizotricha Allman, 1883, one of which is new to science, have been studied.\nThe material originates from the Weddell Sea region and from off Elephant Island and it was collected during several antarctic expeditions with the R.V. Tolarstern\'. Each species is described and figured and its systematic position among allied species discussed. The type material of Schizotricha glacialis (Hickson & Gravely, 1907) and S. turqueti Billard, 1906 has been re-examined and is also described and figured.
