In man}^ other Protozoa, the division figure, especially the 

 achromatic figure, suggests strongly a mitosis, but the chromatin 

 substance which makes up the equatorial plate can hardly be called 

 chromosomes. A typical example of this type is found in the nuclear 

 division of Amoeba proteus (Fig. 65). According to Chalkley and 

 Daniel (1933), the conspicuous granules present, in the resting nu- 

 cleus, under the membrane contain very little chromatin, while 

 abundant chromatin is lodged in the central area. The peripheral 

 granules appear to give rise to achromatic figure. At the beginning of 

 division, the chromatin granules become aggregated in a zone (6); 

 they then assume a ring-form along the periphery of the central mass
