<p>The genus<i> Proctoeces</i> was erected by Odhner ( 191 1) to contain <i>Distonium maculatuni</i> Looss, 1901, from <i>Labrus merula</i> and <i>Crenilabrus spp</i>. at Triest. Odhner had found the parasite in <i>Blennius ocellaris</i> at Naples. One adult specimen from <i>Chrysophrys bifasciata</i> and two immature specimens from<i> lulis lunaris</i> taken in the Red Sea, were described as a new species, <i>Proctoeces erythraeus</i>. Dawes (1946) listed <i>P. erythraeus</i> as a synonym of <i>P. maculatus</i> (Looss) , but the species was recognized by Manter ( 1947) on the basis of six specimens he had collected from <i>Calamus calamus</i> and <i>Calamus bajonado</i> at the biological laboratory of the Carnegie Institution at Dry Tortugas, Florida. Several additional species have been de scribed. Fujita ( 1925) reported a metacercaria from the Japanese oyster, <i>Ostrea gigas</i>, as a new species,<i> Proctoeces ostreae</i>. The paper was translated by R. Ph. Dollfus who noted (p. 57) ,“Il est à souhaiter que des recherches chez les poissons mangers de Lamellibranches, sur les côtes de la préfecture d'Hiroshima, permettent de découvrir des exemplaires complètement adultes de<i> Proctoeces ostreae</i> Fuj., chez lesquels l'extension des vitellogènes et les dimensions des oeufs puissent être observées avec précision; il sera alors possible de savoir définitivement si <i>P. ostreae</i> Fuj. doit ou non tomber en synonymie avec<i> P. maculatus</i> (Looss)." Yamaguti (1934) described<i> P. maculatus</i> from <i>Sparus aries</i>, Sparws macrocephalus, <i>Pagrosomus auratus</i>, and <i>Epinephelus akaara</i> in Japan. Several specimens from <i>Pagrosomus auratus</i>, which differed from<i> P. maculatus</i> in larger size, larger eggs, and trilobed ovary, he described as a new species, <i>Proctoeces major</i>. Yamaguti ( 1938) reported P. nzaculatus from <i>Sensicossyphus reticulatus</i> and described a larva from the liver of the pelecypod mollusk, <i>Brachidontes senhausi</i>, as an unidentified member of the genus Proctoeces. Manter ( 1940) described<i> Proctoeces tnagnorus</i> from a single specimen found in the intestine of<i> Caulolatilus ano</i>,nalus, taken at Cerros Island, Mexico. Hanson ( 1950) identified two specimens collected from <i>Calamus sp</i>. at Bermuda by the late F. D. Barker as <i>Distontuni subtenue</i> Linton, 1907, a species described originally from <i>Calantus calanius</i> in the same area. Comparison of these specimens with those from Tortugas identified by Manter as<i> P. erythraeus</i> established their identity, and<i> P. erythraeus</i> was suppressed as a synonym of <i>Proctoeces subtenue</i> (Linton, 1907). Hanson corrected the statement of Manter (1947), noting that it is the vitellaria, not the uterus, which never extends into the post testicular region.</p>
