Fig. 20. Ellipsoidal cyst with eiglit nuclei sliowing ehromophile ridge 

 extending the full length of the cyst. 



Fig. 21. Spherical eight-nucleate cyst -witli cliromophile ridges on either 

 side and chromatoidal body in the center. 



Fig. 22. Ellipsoidal cyst with bud protruding from the region of the ehro- 

 mophile ridge. One nucleus is located in the bud, four nuclei are left in the 

 cyst, and a small amoebula is in close proximity to the cyst, having just pre- 

 viously budded off. Note the empty space in the cytoplasm and the general 

 thin appearance of the cytoplasm, indicating that part of the cytoplasm has 

 previously passed out of the cyst in forming the earlier amoebulae. 



Fig. 23. Large, eight-nucleate cyst without chromatoidal bodies, bud, or 

 ehromophile ridge. 



Fig. 24. Smaller, eight-nucleate cyst with long chromatoidal body in middle 

 of cyst. The karyosomes are widely dispersed. 



Fig. 25. Eight-nucleate cyst, showing ehromophile ridge. 



Fig. 26. Eight-nucleate cyst with bud showing chromatoidal body and 

 typical dispersion of the karyosome toward the region of the pore, and remnants 

 of ehromophile ridges. One nucleus is in the bud. 



Fig. 27. Seven-nucleate cyst showing bud, large, massed chromatoidal body, 

 and ehromophile ridges in the region of the pore. 



Fig. 28. Six-nucleate cyst with one nucleus in the bud. Chromatoidal body 

 and ehromophile ridge are present. 



Fig. 29. Eight-nucleate cyst with bud and showing peculiarly curved chro- 

 matoidal body in middle of cyst. Chromophile ridge is in the region of the pore.
