SYNOPSIS The oocysts of 2 new species of Eimeria are described from heteromyid rodents. The subspherical to ellipsoidal cocysts of Eimeria reedi from Perognathus formosus averaged 22.6 by 20.8 μ. An ellipsoidal polar granule was present. The oocyst residuum was a single globule about 8 μ in diameter. The ovoid sporocysts averaged 10.9 by 7.7 μ and had a residuum of 6‐12 granules. A Stieda body and substiedal body were present in the sporocysts. Eimeria chobotari oocysts, from Dipodomys merriami and D. microps , were ellipsoidal to ovoid and averaged 47.7 by 35.2 μ. No polar granule was seen. The large oocyst residuum consisted of several granules of various sizes. The ovoid sporocysts averaged 15.8 by 11.3 μ and had a residuum of many small granules. A Stieda body and substiedal body were present in the sporocysts.
