title: [Myxosporidia of the cartilaginous fish of the Patagonian shelf (shore of Argentina)].
abstract: 5 species of myxosporidians of the genus Chloromyxum were found in the gall bladder of Chondrostei from the Pathagonian shelf (Argentina coast). 4 species of them are new ones. This indicates that the species Chloromyxum leydigi mentioned for all Chondrostei is a collective species which needs a revision. Caudal filaments and ribs of the valves of spores of myxosporidians are more developed in species parasitic in fishes getting food from water mass and predators and to a lesser extent in species getting food from the bottom.
