PLATE 9. 
[Figs. 1-6 and 14-21 inclusive were drawn under Zeiss comp. oc. 18 
and l‘o mm. apochromat. Figs. 7-13 were drawn under Zeiss comp, 
oc. 18 and 2 mm. apochromat.] 
Fig. 1. — Trypanoplasma congri. Abnormal division product con- 
taining the entire trophonuclear spindle. 
Fig. 2. — Trypanoplasma congri. Abnormal individual with two 
trophonuclei. 
Fig. 3. — Early rounding-up stage of Trypanoplasma congri. 
Fig. 4. — Later stage of same process. 
Fig. 5. — Still later stage. 
Fig. 6. — Final stage of rounding-up in Trypanoplasma congri. 
Fig. 7. — Normal active individual Heteromita dahlii. 
Fig. 8. — Stage preparatory to division in Heteromita dahlii. 
Fig. 9. — Early stage of division in Heteromita dahlii. 
Fig. 10. — Later stage of division ; one blepharoplast with its attached 
flagella has travelled back and the division of the kinetonucleus is 
almost complete. 
Fig. 11. — The body of the dividing individual has become pear-shaped 
and the dividing kinetonuclei are now at angles to each other. 
Fig. 12. — Later stage of division showing elongation of the dividing 
trophonucleus. 
Fig. 13. — Later stage of division in Heteromita dahlii. 
Fig. 14. — Normal active individual of Trypanoplasmoides in- 
testinalis showing three anterior flagella twined together.
