John E.McCosker,Kiyotaka Hatooka,Kunio Sasaki and Jack T.Moyer Received February( 1,1984)

Abstract New records,new extralimital synonymies,and a key to the species of the Japanese moray eels,genus Uropterygius are presented.The valid Japanese species(in boldface)and their synonyms are:U.bennettii(GUnther,1870)= U.okinawae Jordan et Snyder,1901;Gymnomurae- na brevicauda Regan,1903;Scuticaria unicolor Seale,1917;and U.sealei Whitley,1932;U.micro- pterus(Bleeker,1852)= U.tinkhami Fowler,1945;U.macrocephalus(Bleeker,1865)=Gymnomurae- na nectura Jordan et Gilbert,1882;Anarchias knighti Jordan et Starks,1906;and U.reidi Schultz, 1943;U.marmoratus(Lacepede,1803);U.concolor Ruppell,1837,and;U.nagoensis Hatooka,1984. Uropterygius macrocephalus is recognized as a widespread trans-Pacific species,and comments are included concerning the distribution of muraenid and ophichthid eels .
