amitotically (Fig. 18). In Cnidosporidia the minute nucleus fre- 

 quently undergoes a division which could be considered only 

 as amitosis (Fig. 18). In the case of external budding in the

Suctoria, as for instance, Ephelota, the macronucleus branches 

 out a small portion of its body into each of the developing buds, 

 and nuclear constrictions result in the forming of many young 

 individuals (Fig. 18).
