C. gallinarum Martin and Robertson (Fig. 157, I, m). 11-20/x by 

 5-6^; in the caeca of turkeys and chicks. Morphology (Boeck and

Flagella 12 or more; in stomach of ruminants or in caecum and 

 colon of horse.

 or anterior; 12-15 long flagella near anterior end, vibrate in unison. 

 Weissenberg (1912) considered this genus to be related to Lopho- 

 monas (p. 407), but organism lacks axial organellae;in Cyclops and 

 alimentary canal of ruminants and horse.
