SYNOPSIS. Eight new species of Trichodina are described from freshwater fishes of the Southeastern U.S.: T. davisi from Roccus saxatilus (Walbaum), T. funduli from Fundulus notti (Agassiz), T. globosa from Etheostoma radiosum (Hubbs and Black), T. hoffmani from Etheostoma edwini (Hubbs and Cannon), T. hypsilepis from Notropis hypsilepis Suttkus and Raney, T. microdenticula from Dorosoma petenense (Gunther). T. noturi from Noturus leptacanthus Jordan, and T. salmincola from Salmo gairdneri Richardson. Nine species of Trichodina are redescribed: T. californica, T. discoidea, T. fultoni, T. pediculus, T. platyformis, T. reticulata, T. sp. (? T. nigra), T. tumefaciens , and T. vallata. The name T. pediculus is re‐erected for the form that occurs on largemouth bass. Host fish were collected from 36 geographic locations in 10 states (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee). A total of 939 fish of 46 species was examined for trichodinid parasites. Two methods of impregnating formalin preserved specimens of Trichodina with silver are discussed. A key to the species of Trichodina reported from North American freshwater fishes is given.
