| Twelve species of Pinnotheridae from Santa Catarina and Rio Grande do Sul States, Brazil, are redeseribed and illustrated; a key of identification is presented. Clypeasterophilus stebbingi Rathbun, 1918; Pinnotheres garthi Fenucci, 1975 and Pinnixa brevipollex Rathbun, 1898 are reported for the first time for Brazil. Clypeaslerophilus stebbingi Rathbun, 1918 and Tumidotheres maculatus Say, 1818, are new record for Santa Catarina. Fabia insularis Melo, I971 and Pinnotheres emiliai Melo, 1971 are revalitaded; Fabia sebastianensis Rodrigues da Costa, 1969; Pinnotheres garthi Fenucci, 1975; Pinnotheres emiliai Melo, 1971 and Pinnixa patagoniensis Rathbun, 1918 are new records for Rio Grande do Sul. Pinnixa brevipollex Rathbun, 1898 is a new record for Santa... |

| A new species of Palaemon, P. vicinus spec. nov., is described from the tropical eastern Atlantic. The new species is very close to P. elegans Rathke, 1837, under which name it was previously recorded from West Africa. Palaemon vicinus spec. nov. is easily separated from P. elegans by possessing a small tooth on the fifth abdominal pleuron (quadrate in P. elegans) and by having 2-3 rows of setae in the grooming brush of the fifth pereiopod (4-5 in P. elegans). The discovery of the new species amongst material identified as P. elegans further highlights the need to reassess species level characters in the genus Palaemon. |

| The first juvenil stage of Aegla prado Schimitt, 1942 is described and illustrated. The species A. prado showed a direct development, without the swimming free larval form. The most important appendages of the first juvenile stage were analysed: first and second antenna, mandible, first, second and third maxillipeds, first and fifth pereopods, telson and uropods. Setal formula for the first stage and setae characteristics are presented. |

| Identification and utilization of proxy characters in extant families has been accomplished with success for fossil members of the Calappidae, Hepatidae, Necrocarcinidae, Matutidae, and Hexapodidae. The fossil and extant Raninidae have been revised using primarily hard-part morphology preserved in the fossil record although formal designation of “proxy characters” has not occurred. Hard-part characters can also be used to differentiate among members of the Atelecyclidae and the Cheiragonidae. Thus, the method of using proxy characters is demonstrably suitable for application to a difficult group like the Xanthoidea. |

| The trembling of legs followed by increasing paralysis and eventual death, were recorded on specimens of the above sp from Sete region. EM studies of tissue showed paraspherical bodies measuring approx 61 nm with a size range of 58-65 nm. By experimentally infecting specimens with a purified viral suspension the following pathogenesis was observed: in greater than 60 per cent of the specimens, trembling of the legs began within 6 days, growing very pronounced on the 8th day, leading to a general paralysis and 9 days after the infection a mortality rate of 70-80 per cent was recorded. The following characteristics of the virus are noted: its cytoplasmic localisation, paraspherical form, size ranging from 60-70 nm and the absence of an envelope. Considering... |

| In the present study, the feeding habits of the bathypelagic shrimps Sergestes arcticus, S. robustus, Pasiphaea sivado, P. tarda, P. multidentata and Psathyrocaris infirma), occurring on the continental slope of the Bay of Biscay, were examined. It was concluded through the present observations that these shrimps use the pelagic resources from the environment. On the other hand, their spatial distribution in different layers prevents any trophic competition between them. The nature of the prey organisms is widely determined by the size, the efficiency of the catching techniques, but also by the possibility of special detection (the hypothesis of ocular detection of euphausiids by P. sivado). The absorption of sediment, during the rest hours, is supposed to... |

| New fossils referable to the Cancridae Latreille, 1802 extend the known stratigraphic range of the family into the middle Eocene and the geographic range into South America. Each genus within the family has been reevaluated within the context of the new material. A suite of diagnostic characters for each cancrid genus makes it possible to assign both extant and fossil specimens to genera and the two cancrid subfamilies, the Cancrinae Latreille, 1802, and Lobocarcininae Beurlen, 1930, based solely upon dorsal carapace morphology. Cheliped morphology is useful in assigning genera to the family but is significantly less useful at the subfamily and generic level. Each of the four subgenera sensu Nations (1975), Cancer Linnaeus, 1758, Glebocarcinus Nations,... |
