 and lower small intestine tf chicken; cause of acute coccidiosis (Tyz- 

 zer); in caecal contents of California quail (Henry); schizogony in 

 caecum; oocysts 19.5-26/i b}^ 16.5-23iu; sporulation in 48 hours; 

 heavily infected caecum highly haemorrhagic.

 of chicken; oocysts subspherical, 16.2/i by 15.5^; sporulation in 48 

 hours.

 tine of chicken; also in California quail (Henry); oocysts oval, 

 17.7-20.2^ by 13. 7-16. 3m; sporulation in 20 hours; associated 

 with serious chronic coccidiosis (Tyzzer).

 oval, 21.5-42.5m by 16.5-29.8m.

 vate, 13-23m by 11-18m; sporulation in 48 hours.
