| 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. |

| We present a numerical model of sedimentary early diagenetic processes that includes oxic and anoxic mineralization. The model belongs to the new wave of early diagenesis models that account for depth-dependent bioturbation and porosity profiles; it can be used both for calculating steady-state conditions and transient simulation. It was developed to reproduce the cycling of carbon, oxygen, and nitrogen along the ocean margin; it resolves the sediment-depth profiles of carbon, oxygen, nitrate, ammonium, and other reduced substances. Organic carbon is modeled as two degradable fractions with different first-order degradation rates and nitrogen:carbon ratios, to account for the decreasing reactivity and N/C ratio of the organic matter with depth into the... |

| A new coralline sponge, <i>Willardia caicosensis</i>, assigned to the family Timeidae, is described from the deep fore reef off the Turks & Caicos Islands, tropical western Atlantic Ocean, where it is common at depths ranging from 100 to 119 m. Individuals vary up to 15-20 cm in width. The relatively thin aragonitic skeleton is covered with delicate pillars up to + 1 mm. The living tissue is restricted to the spaces between pillars and a thin sheet lying above the calcareous skeleton. Exhalant canals converge upon regularly spaced central oscules on the sponge surface. Siliceous spicules include tylostyles and amphiasters which are secondarily embedded in the aragonitic moiety of the skeleton. In addition, ultrastructural characters of... |

| 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. |

| A new species of Parthenopidae from the East Pacific belonging to the genus <i>Parthenope</i> Weber is described and illustrated. <i>Parthenope johngarthi</i> n. sp. was collected along the west coast of Mexico, off the coast of Jalisco and Colima. <i>Parthenope johngarthi</i> is readily distinguished from species of other genera of Parthenopidae from the East Pacific by the shape of the tuberculate carapace, the relative lenght and shape of the chelipeds, and the shape and relative size of segments of walking legs. It is closely related to <i>P. exilipes</i> (Rathbun, 1893) but differs from the latter by its slender and almost smooth walking legs, its slender and less densely tuberculate chelipeds, and by... |

| <i>Pontocypria coriocellae</i> sp. n. is described from Papua New Guinea. The species was found inside the oral tube near the radula, of <i>Coriocella nigra</i> Blainville, 1824 (Gastropoda, Prosobranchia, Lamellariidae). Because of its morphology and its mode of life, the new species may be considered as an occasional commensal of its gastropod hosts. It is the first <i>Pontocypria</i> species to be found inside its host. The distribution of the genus <i>Pontocypria</i> is discussed. |

| A new test system is described for the evaluation of toxic levels of liposoluble products in the aquatic food chain using <i>Artemia</i> and <i>Mysidopsis bahia</i> (M.) as experimental animals. For this, freshly released juveniles (<24h old) of <i>M. bahia</i> are transferred to the experimental bioassay test system, cultured under standard conditions and fed 24h old purposely contaminated <i>Artemia</i> nauplii. After 11 days, data on survival, reproductive characteristics, individual length and dry weight are recorded and treated statistically. |

| <i>Mangalocypria</i>, a new genus of the tribe Thalassocypridini, is described, with a new species, and two previously described species, from Papua New Guinea, the Comoros and Indonesia. The new genus has a remarkable set of characters separating it from other members in the tribe: thin-shelled, translucent and smooth valves, V-process of lower lip developed as a rake, and postero- distal claw of furca fixed to shaft without a joint. The affinities of <i>Mangalocypria</i> gen. nov. with other genera is discussed, and some taxonomical problems in the tribe Thalassocypridini are commented upon. The diagnostic value of incompletely differentiated Zenker organs of premature males is discussed. |
