Fig. 14. Motile amoeba showing hyaline, rounded pseudopodia with sharp 

 demarcation between ectoplasm and endoplasm; nucleus with somewhat massed 

 creseentrio karyosome in darkened halo and chromatin granules encrusted on 

 nuclear membrane. 



Fig. 15. Uninucleate cyst with no glycogen mass but with a number of 

 small, spherical chromatoidal bodies. The karyosome is located in a darkly stain- 

 ing halo containing four small granules. Nuclear membrane is encrusted with 

 heavy chromatin blobs. 



Fig. 16. Binucleate cyst with glycogen mass on the margin of which are 

 chip-shaped chromatoidal masses. Nuclei in early prophase, the karyosome break- 

 ing into two portions connected by an intradesmose. Characteristic peripheral 

 chromatin encrusted on nuclear membrane.
