ILLUSTRATIONS 
[Drawings by Haughwout.] 
PLATE 1. CAMERA LucIDA DRAWINGS OF CARABAO TRYPANOSOME 
Fics. 1 to 9. Forms showing normal relations of nucleus and parabasal 
body. 
8 and 9. These show a chromatinic body lying between the parabasal 
and the proximal end of the flagellum—probably a blepharoplast. 
10 and 11. Apparent splitting of the parabasal. 
Fig. 12. Elongated individual—probably a predivision form. 
PLATE. 2. CAMERA LUCIDA DRAWINGS OF CARABAO TRYPANOSOME; ABERRANT 
TYPES 
Fic. 13. Heterotypical (precocious?) division of the nucleus to form two 
daughter nuclei. The parabasal body lies beside the posterior 
nucleus. 
Fieés. 14 to 23. Posterior migration of the nucleus to form a pseudo-cri- 
thidial type of trypanosome. 
24 and 26. The parabasal is overlying the nucleus in each case. 
Fic. 25. The parabasal lies anteriorly to the nucleus which has migrated 
posteriorly. 
PLATE. 3. DIAGRAMMATIC REPRODUCTION OF CAMERA LUCIDA SKETCHES OF 
TWENTY-FIVE SPECIMENS OF THE CARABAO TRYPANOSOME 
Figs. 1, 2, 6, 7, 11, 12, 18, 14, 15, 16, 17, 21, and 22. Show the normal 
relation between the nucleus and parabasal. 
8 and 9. Show an approach to the true crithidial form. 
10 and 18. Show an anterior shifting of both the nucleus and the 
parabasal body. 
3, 4, 5, 19, 20, 23, 24, and 25. Show stages in the posterior migration 
of the nucleus and the assumption of the pseudo-crithidial form. 
TEXT FIGURES
