Fig. 16. Amoeba with one large and two small probably daugliter nuclei. 



Pig. 17. Reorganization of nucleus of daughter amoeba in which the two 

 chromatin masses are late fusing. 



Fig. 18. Amoeba with four nuclei of same size. 



Fig. 19. Amoeba elongated. Resting nucleus with little peripheral chromatin. 

 Pseudopodium ectoplasmie as in those of figures J-7 and 16-18. 



Fig. 20. Amoeba with three nuclei in same stage of late prophase. 



Fig. 21. Amoeba in which the cytoplasm failed to divide. Nuclei reorgan- 

 izing. 



Fig. 22. Amoeba with two nuclei, in very early prophase. Peripheral chro- 

 matin very evident. 



Fig. 2.3. Amoeba with three nuclei, one of which is in resting condition, one 

 is in very early prophase, and the other in late prophase. 



Fig. 24. Amoeba with three nuclei in same stage. 



Fig. 25. Daughter amoeba in which the two chromatin masses are nearly 

 fused, but the nucleus is not rounded off. Remains of nuclear connection visible. 



Fig. 26. Amoeba with two nuclei in early telophase, the position of which 

 indicates that plasmotomy may occur. 



Fig. 27. Amoeba with large nucleus and no chromidia. 



Fig. 28. Small amoeba with small nucleus and few remaining chromidia. 



Fig. 29. Endogenous bud in vacuole. 



Fig. 30. An individual showing an endogenous bud nearly cut off. 



Fig. .31. Nucleus larger than that in figure 28. Few chromidia. 



Fig. 32. A budded individual in which the nucleus is not organized. 



Fig. 33. Binucleate individual about to form an exogenous bud. Nuclei are 

 very light. Chromidia present. 



Fig. 34. An amoeba constricting off a cytoplasmic lobe at the periphery 

 containing chromidia; vacuole and chromidia in cytoplasm, nucleus with heavj' 

 peripheral chromatin and karyosome with little chromatin. 



Fig. 3.5. Endogenous bud in vacuole. Nucleus not well organized. 



Fig. 36. Endogenous bud containing chromidia almost separated from parent 

 individual.
