| Sublittoral meiofauna of 24 stations was monitored over 4 years (1984-1987) in and around a dumping site for TiO<sup>2-</sup> acid waste in the Southern Bight of the North Sea off the Dutch coast. The meiofauna was examined quantitatively and qualitatively with special reference to the nematode and the copepod community structure down to species level and to the trophic structure of the nematodes. Biological, sedimentological, geographical parameters and the concentration of several heavy metals were subject to multivariate statistical analysis and classification techniques to evaluate the impact of the TiO<sup>2-</sup> dumping activities. The meiofauna is dominated by nematodes, copepods, gastrotrichs and turbellarians. There is a... |

| Lack of attention to determining the homology of character states is recognized as being responsible for the ever increasing numbers of phylogenetic schemes for the Crustacea that appear and disappear so rapidly. Detailed study of musculature. segmentation and setation of the limbs of all 10 orders of copepods revealed numerous phylogenetically informative characters. based on segmental fusion patterns and the presence of individually identified setation elements. Simple counts of limb segments (or of setae) were found to be virtually useless for constructing phylogenies in the copepods. This conclusion can probably be extended to other crustacean groups. |

| The tantulus larva ofMicrodajus langi is redescribed using Scanning Electron Microscopy. Thoracopods 2–5 have poorly developed but fully armed endites. Thoracopods 1–5 are biramous, with each ramus represented by a minute segment. A new species,M. pectinatus, is described from a tanaid host collected in the Rockall Trough, off the west coast of Scotland. A system of homologies for the portopodal segments of the thoracopods of the tantulus larva is proposed. Some aspects of the musculature of the adult male are described for the first time. |

| Males of two new species of Cylindropsyllus Brady, 1880 (Cylindropsyllidae) are described. Cylindropsyllus ibericus sp. n. is based on a single specimen from Portugal previously misidentified as C. laevis Brady, 1880; C. govaerei sp. n. is reported from Corsican shell-gravel. The boreomediterranean distribution of C. laevis is confirmed and a key to the species of Cylindropsyllus is presented. Redescriptions are provided for the two species of Cylinula Coull, 1971, the type species C. proxima Coull, 1971 and C. arganoi Cottarelli and Venanzetti, 1989. The relationships of Cylindropsyllus, Cylinula and Evansula Sars, 1909 are briefly discussed. |

| Archisenia gen. nov. is proposed to accommodate the sibirica-group of the genus Danielssenia Boeck, 1872. Re-examination of Alaskan material of D. stefanssoni Willey, 1920 has shown the latter species to be a junior synonym of D. sibirica Sars, 1898, the type and only species of the new genus. Danielssenia robusta Sars, 1921 and Fladenia intermedia (Wells, 1965) are synonymous and consequently F. robusta comb. nov. becomes the type species of the genus Fladenia Gee & Huys, 1990. Danielssenia similis Chislenko, 1971 is regarded as species inquirenda and the genus Danielssenia is redefined from the type species D. typica Boeck, 1872, and two other species (D. quadriseta Gee, 1988 and D. reducta Gee, 1988). The status of D. fusiformis (Brady, 1880) nec... |

| The harpacticoid copepod subfamily Thompsonulinae Lang, 1944, formerly recognized as belonging to the family Tachidiidae (Lang, 1948) is raised to family rank and redefined to include only the genera Thompsonula T. Scott and Caribbula gen. nov. Thompsonula hyaenae (I. C. Thompson) and T. curticauda (Wilson) are redescribed and refigured. Re-examination of the original material showed that Wilson's Rathbunula agilis is synonymous with T. curticauda and not with T. hyaenae, as suggested by Lang (1948). It is now clear that the two species of Thompsonula have distinct distributions, T. curticauda being confined to the North American continent and T. hyaenae to western Europe and the Mediterranean. The genus Caribbula is established to accommodate the type... |

| A new family Cristacoxidae is proposed to accommodate the monotypic genera Cristacoxa gen. nov., Noodtorthopsyllus Lang (ex Canthocamptidae) and Cubanocleta Petkovski (ex Laophontidae). Cristacoxa petkovskii gen. et spec. nov. is described on the basis of a single male collected from coralline sand of Bonaire, West Indies. N. psammophilus Noodt and C. noodti Petkovski are redescribed and refigured on the basis of new material from the Galapagos (Isla Santa Cruz), the West Indian Islands (Curaçao, Klein Curaçao, Bonaire) and the Canary Islands (El Hierro, Tenerife). The new family is characterised by the presence of an outer spinous process on the first antennular segment, the absence of the antennary exopod, the uniramous mandibular palp, the presence of... |

| Knowiedge on community structure of North Sea meiofauna has greatly increased recently. A quasisynoptic picture of meiofauna densities and copepod community structure from 171 stations of the southern North Sea, sampled in April–May 1986, has been obtained during the North Sea Benthos Survey. Latitudinal patterns in meiofauna abundance and copepod weight, abundance and diversity exist in an area between 51°30'N and 58°30'N. Using TWINSPAN-classification five major groups of copepod species can be recognized which are related to sediment type, latitude and depth. The part of the meiofauna in total benthic energy flow, their role in the benthic food web and in biogeochemical cycles is discussed based on existing literature. There are still considerable gaps... |

| Amphicrossus altalis, n.sp., belonging to the primitive poecilostomatoid family Erebonasteridae, was found at a depth of 2420 m at the Juan de Fuca Ridge off British Columbia. The male of an Amphicrossus species is described for the first time. The new copepod differs from the two recognized species of Amphicrossus in its body surface being not highly ornamented with spinules, its smooth anterior surface of the labrum, and the dimensions of the fifth leg. New records for Benthoxynus spiculifer Humes, 1984, Aphotopontius forcipatus Humes, 1987, and Stygiopontius quadrispinosus Humes, 1987, are included. The clausidiid genus Tychidion is redescribed and its taxonomic position discussed. |

| A new species of Erebonasteridae, Amphicrossus pacificus, is decribed on the basis of a single female from a depth of 155 m north of New Caledonia in the Grand Passage zone. The new species is closely related to Erebonaster spinulosus Humes and for that reason the latter is transferred to the new genus Amphicrossus. Differences in body ornamentation and armature of maxilla, maxilliped and P4 serve to distinguish Amphicrossus and Erebonaster. Other noticeable discrepancies are found in the structure of the rostrum, the shape of the thoracic epimera and the design of the fifth pair of legs. A peculiar structure, the "sensory area", is shown on the posterior surface of enp-2 P2 in both Amphicrossus species which can be differentiated from each other on the... |

| A new genus, <i>Centobnaster</i>, is proposed to accommodate a single female collected from deep water northeast of New Caledonia. <i>Centobnaster humesi</i>, new species, is placed in the family Erebonasteridae (Poecilostomatoida) on account of the distinct palp on the mandible and the external structure of the female genital system, comprising ventral paired copulatory pores and dorsolateral gonopores. <i>Centobnaste</i>r is considered the most primitive poecilostomatoid copepod known today because of the combined presence of 7-segmented antennules, a separate palp and unmodified gnathobase on the mandible, ventrally located paired copulatory pores, and midventral fifth legs jointed by an intercoxal sclerite. The... |

| A new order, Gelyelloida, is proposed for Gelyella Rouch & Lescher-Moutoué,1977(ex Harpacticoida), an enigmatic genus of freshwater-inhabiting copepod from European karstic systems. The new order is characterized by a unique combination of generalised gnathostomous mouth parts and unusual derived features, some of them suggesting a possible neotenic origin for the order. It is suggested that gelyellids have had a long evolutionary history and separated as an early offshoot of the main cyclopoid lineage. |

| A new family of harpacticoid copepods, Adenopleurellidae, is proposed to accommodate the genera <i>Adenopleurella</i>, new genus, </i>Sarsocletodes</i> Wilson, <i>Miroslavia</i> Apostolov, and <i>Proceropes</i>, new genus. The genus <i>Sarsocletodes</i> is removed from the Laophontidae T. Scott on the basis of the reduced nature of leg 1 which cannot be attributed to heterochronic (neotenic) events. <i>Sarsocletodes secundus</i> Smirnov is placed in a new genus, <i>Proceropes</i>, on account of the primitive P1 and P5, and is considered the most primitive member of the family. <i>Miroslavia longicaudata</i> is excluded from the Cletodidae T. Scott and is most... |
