| The brine shrimp <i>Artemia</i> produces embryos (cysts) in a state of obligate dormancy called diapause. Diapause is terminated by a variety of treatments, including dehydration. Previous work suggested that some cysts can be induced to reenter diapause when exposed to prolonged anoxia. Results presented in this paper indicate that heat shock (42-43°C) can also lead to diapause induction. The basis for this proposal is the finding that the final hatching level of heat-shocked cysts is increased by a post-heat dehydration, a treatment known to terminate diapause. The respiration rate of postheat-shocked cysts was found to be much lower than controls. Electrophoretic profiles of proteins in extracts from control and heatshocked cysts suggest... |

| In this paper fossil species from the Neogene of Southern Europe or the Vienna Basin, and Recent ones from the Lusitanian and Westafrican regions, which have been incorrectly assigned to <i>Nassa semistriata</i> Brocchi, 1814 (= <i>Nassa semistriatus</i>) are described, figured and discussed. It appears that: 1- mostly commonly specimens designated as <i>Nassarius semistriatus</i> belong to <i>N. elatus</i> (Gould, 1845). This is a relatively common species, practically ignored by both zoologists and paleontologists. We have been able to trace it from the Upper Middle Miocene to Recent. 2- Some recent specimens designated as « <i>Nassa semistriata</i> » belong, in fact, to <i>Nassarius... |

| In this paper 20 taxa of the genus <i>Nassarius</i> s. l., often classified by the authors under the sub-genus <i>Uzita</i> H. et A. Adams, 1853, are described and discussed. The specimens are preserved in the zoological and paleontological collections of the « Institut Royal des Sciences Naturelles » in Brussels. They are either fossils from European and North-African Neogene strata, or recent species from the Mediterranean, Lusitanian and West-African regions. However from the British Museam of Natural History and from the « Museo Civico di Storia naturale di Milano » we have obtained photographs of the original matrial of <i>N. denticulatis</i> (A. Adams, 1852) and of <i>N. prismaticus</i> (Brocchi, 1814)... |

| In the present paper the authors have described, figured or discussed 37 species of <i>Nassarius</i>, 6 species of <i>Bu//ia</i>, 2 species of <i>Cy//ene</i> and one species of <i>Demou/ia</i>. Among the <i>Nassarius</i>, <i>N. ambiguous</i> (PULTENEY, 1799, non SOLANDER, 1766) and <i>N. margaritiferus</i> (DUNKER, 1847) are doubtful species for the West-African coast. Six new species of <i>Nassarius</i> have been described: <i>N. at/antideus, N. bruuni, N. gruve/i, N. mega/oca//us, N. parcipictus</i> and <i>N. pseudopoeci/ostictus</i>. <i>Nassarius muelleri, N. plicatellus</i> and <i>BuIlia granulosa</i> are... |
