8. The mitotic and related phenomena in Euglena agilis give 

 additional evidence of the primitive character of the Phyto- 

 mastigoda. The development of the motor organoids indicate 

 relationship with diphasic amoeba on the one hand and with the 

 complex parasitic flagellates on the other. 



9. Changes in the chromatophores during the division and 

 vegetative periods, as well as their changes when the Euglense are 

 subjected to different cultural conditions indicate that these 

 structures are not satisfactory criteria upon which to base the 

 classification of the group.
