both possess two nuclei characterized by a kuryosome and deeply 

 staining reticulated cytoplasm. The deeply staining grains in 

 the schizonts (Fig. i, m] already described, may become dispersed 

 in the cytoplasm, though occasionally one sees similar bodies in 

 the naturally infected forms (Fig. 2, b).
