Abstract

In a survey of 150 Western Painted turtles (Chrysemys marginata bellii) 56 per cent were found to be infected with one or more species of coccidia. Species found were: Eimeria chrysemydis n. sp. Incidence: 34 % Oocysts oval, 23µ x 15µ; differs from E. delagei in that the granular mass does not form a crescent and vacuole, in that there is no definite arrangement of sporocysts, and in host and geographical distribution. Eimeria delagei var. marginata n. var. Incidence 6.7 per cent. Differs from E. delagei in that segmentation does not result in five equal spheres and in that there are differences in size, shape, host and geographical distribution. Eimeria mitrarium (Laveran and Mesnil). Incidence 32 per cent. This is a new host and geographical record for the species.
