94 ELECTRON-MICROSCOPIC STRUCTURE OF PROTOZOA 



Plate X 



Fig. 33. Section through two individuals of Plasmodium berghei 

 in single host erythrocyte. Each contains large food vacuole filled 

 with material resembling host cell cytoplasm. Food vacuole in cell 

 at right indents nucleus. Assorted cytoplasmic membranes visible 

 in both individuals. Small opaque granules enclosed in vesicles are 

 residual hematin pigment. X 40,000. From Rudzinska and Trager, 

 1959. 



Fig. 34. Section through part of Plasmodium berghei embedded in 

 host erythrocyte. Note double membrane between host cytoplasm, 

 below, and parasite. Lamellar body shown at center; tip of elongate 

 food vacuole at left. X 60,000. From Rudzinska and Trager, 1959. 



Fig. 35. Two dried whole cells of Chromulina pleiades. X 2,800. 

 From D. R. Pitelka and E. C. Dougherty, unpublished. 



Fig. 36. Section of Chromulina psammobia, showing kineto- 



rhizoplastic complex. See Text-fig. 6, showing the same structures 



in opposite (left-right) orientation. X 38,000. From Rouiller and 



Faure-Fremiet, 1958a.
