Examination of the feces of an emydid turtle, a watersnake, and a passeriform bird for coccidian parasites yielded some new host and geographic distributional records. Oocysts of Eimeria cooteri McAllister and Upton, 1989, and Eimeria marginata (Deeds and Jahn, 1939) Pellérdy, 1974, occurred in an eastern river cooter, Pseudemys concinna concinna, from Arkansas, U.S.A., Eimeria hydrophis Wacha and Christiansen, 1974, was found in a plain-bellied watersnake, Nerodia erythrogaster, from Arkansas, and Isospora zimmermani McAllister and Hnida, 2023, was found in a barn swallow, Hirundo rustica, from Texas, U.S.A. Mensural data as well as new photomicrographs are provided for each coccidian.
