Seven of these species are reported for the first time from the eastern Mediterranean and three from the Aegean Sea. For the 19 more interesting species found, information on their distribution and their habitat is given. The numbers of decapods known from the entire Mediterranean, the Adriatic Sea, the coast of Israel and the Black Sea, according to the existing literature, are estimated. The affinities among the decapod faunas of the above areas are estimated by the coefficient of CHEKANOWSKI together with the number of species common to each pair of areas. The most strongly related fauna to that of the Aegean Sea is the fauna of the Adriatic. The fauna of the coast of Israel is more related to that of the coast of Cyprus although their degree of affinity is lower than that between Adriatic and Aegean. The two pairs of areas have an affinity with each other of about 60 %. The Black Sea has a low affinity with the other areas.<CENTER><P> Kurzfassung.</CENTER><P> Koukouras, A. & Dounas, C, & Turkay, M. & Voultsiadou-Kokoura E.
