Conteúdo: 	This paper is a connected study of the Myxosporidea, Ciliata, Rhizopoda, Eimeridea and Gregarinida that live as parasites on the fresh-water and marine fish found in South American waters.It is demonstrated that spores of one species of Eimeridea (Cariniella carinii Pinto, 1926) live in the reproductive organs of an Oligochaet worm (Pheritima hawaiana R.) a worm that can serve as food for a fresh-water fish (Rhamdia quelen). In the intestine of this fish are found the spores of Carinniella carinii, but these do not undergo any development within this fish. In the reproductive organs of Pheritima hawaiana spores of Monocystis sp. wer also observed, which pass throuigh the digestive tract of Rhamdia quelen without producing parasitism in the fish. Then follows a general classification of the Myxosporidea as proposed by R. Kudo in his important treatise, published in 1919. On page 5 - 9 is given a list of the Protozoa studied in this paper, a list of the hosts, the infested organs, and observations. Henneguya wenyoni was described from the gills of a fresh-water fish (Astyanax fasciatus Cuv.) where it produces tumors. After the above mentioned species had been described, it was observed that it can fix itself in the intestine of the same host. Coistia necatrix (Henneguy, 1883) was not observed in Brazilian fishes.
The name of Costia Kirchner, 1867, being preoccupied to designate a hymenopterous insect, is untenable, and the new name of Ichtyobobo is proposed as a substitute for Costia Leclercq, 1890. The flagellate ectoparasite of fishes, discovered by Henneguy, should be designated as Ichtyobobo necatrix (Henneguy, 1883).
