The genus Hippolyte Leach in the East Atlantic and the Mediterranean is revised and a list of the world species is given. Eleven species occur in the area studied: H. coerulescens (Fabricius), H. garciarasoi spec. nov., H. inermis Leach, H. lagarderei d'Udekem d'Acoz, H. leptocerus (Heller), H. leptometrae Ledoyer, H. niezabitowskii spec. nov., H. palliola Kensley, H. prideauxiana Leach, H. sapphica d'Udekem d' Acoz, H. varians Leach. An elaborate key, complete descriptions and illustrations of all species are provided, while their ecology is discussed in detail. A morphological account is also given for the species occuring in the Suez Canal: H. proteus (Paulson) and H. ventricosa H. Milne Edwards. It is shown that H. prideauxiana (previously H. huntii) and H. varians display important geographical variations. H. longirostris proves to be a junior synonym of H. leptocerus but part of the specimens previously referred to as H. longirostris belong in fact to a new species: H. garciarasoi spec. nov. The latter is not very variabie but it is extremely close to H. leptocerus which itself displays extraordinary variations within individual populations and on a geographical scale. H. sapphica presents discontinuous variations: it comprises a long-rostred form (forma A) and a short-rostred form (forma B). H. niezabitowskii spec. nov. is a new species possibly endemic in the Adriatic and Ionian Seas and morphologically close to H. inermis and to the Mediterranean populations of H. varians. H. coerulescens presents some neotenic characters.
