158 SPOROZOA. 



1. Family EIMERIID^ Leger, 

 emend. Hoare, 1933. 



Schizogony and sporogony are very uniform in character 

 throughout the family, but variations occur in the number of 

 the sporocysts and the sporozoites developed within the 

 oocyst. The family is divided into six subfamilies on this 

 latter basis.
