FURTHKE NOTES ON A TRYPANOSOME. 
139 
Fig. 1. — Resting phase, showing longitudinal division of the kineto- 
nucleus. 
Fig. 2. — Early stage in develoinnent of flagellum. 
Figs. 3, 4 and 5. — Stages showing newly-formed flagellum. 
Figs. 6 and 7. — Crithidial stages. 
Fig. 8. — Trypanosome phase. 
Fig. 9. — Trypanosome showing lilepharoplast, granule at posterior 
end, and the structure just anterior to the trophonucleus. 
Figs. 10 and 11. — Trypanosome phase. 
Fig. 12. — Early division phase. Note condition of trophonucleus, 
kinetonucleus and hlepharoplast. 
Fig. 13. — Division stage showing spindle. 
Fig. 14. — Later division stage. 
Fig. 15. — Division stage showing trophonucleus spindle and also 
second division of the kinetonucleus. Tliis is a rather unusual appear- 
ance. 
Figs. 1(5 and 17. — Later division stages. 
Fig. 18. — Division of Trypanosome. 
Fig. 19. — Division of Trypanosome. 
Figs. 20-22. — Division stages where the protoplasm divides from the 
posterior end. 
Fig. 23. — Rather unusual appearance where the posterior part of a 
dividing Trypanosome has formed a large I’ounded mass. 
Fig. 24. — Division stage showing irregular splitting of the proto- 
plasm. 
Fig. 25. — T. raiae from the skate's hlood. Note this is drawn at 
a much smaller magnification (x IGOO) than remaining figures.
