FURTHER OBSERVATIONS ON CMCAL PARASITES OF FOWLS. 79 
Fig. 2. — Tailed form. 
Fig. 3. — Rounded form, showing chromatin masses in the nucleus. 
Fig. 4. — Very small form. 
Fig. 5. — Early division stage of small Chilomastix gallinarum. 
Fig. 6. — Later stage of division. Only one of the two flagella is 
shown in one of the division products. 
Fig. 7. — Resting aflagellate form of Chilomastix gallinarum 
prior to encystment. 
Fig. 8. — Beginning of the formation of the cyst wall. 
Fig. 9. — Late stage in the encystment of Chilomastix gallinarum. 
Fig. 10. — The cyst of Chilomastix gallinarum. 
PLATE 11. 
Figs. 11-30. — Trichomonas Gallinarum. 
Fig. 11. — Active Trichomonas gallinarum. 
Fig. 12. — Elongate active Trichomonas gallinarum. 
Fig. 13. — Trichomonas gallinarum with axostyle. 
Fig. 14. — Active form, showing cytostome. 
Fig. 15. — First stage of longitudinal division. The blepharoplast 
has divided ; two basal granules with their flagella remain in connec- 
tion with the old line and membrane flagellum. A new line has grown 
out from the other two granules. 
Fig. 16. — Later stage in longitudinal division. The new blepharo- 
plasts have moved apart, but are connected by a chromatic band. 
Fig. 17. — Later stage of longitudinal division. 
Fig. 18. — First stage of transverse division. 
Fig. 19. — Later stage transverse division. 
Fig. 20. — Still later stage of transverse division. This stage shows 
the arrangement of the chromatin in the nucleus at the time of 
division. 
Fig. 21. — Later stage transverse division. 
Fig. 22. — Later stage transverse division. 
Fig. 23. — Transverse division. 
Fig. 24. — Probably late stage transverse division ; the line between 
the blepliaroplasts has disappeared. 
Fig. 25. — First stage oblique division. 
Fig. 26. — Later stage oblique division. 
Fig. 27. — Still later stage oblique division.
