Actinophrys-like rays were protruded — the corpuscles 

 still remaining quite motionless, and a few of the 

 granules being still green {d). The latter soon became 

 quite colourless ; whilst the rays grew rather longer {e\

 Transformations of Chlorophyll Corpuscles. ( X 600.) 

 a. Pale, unaltered Chlorophyll Corpuscles of Nitella. 

 h. Others lying side by side with former, but larger, of a darker green, 

 and slightly granular. 



c. Decolourization advancing — a few granules still green. 



d. Similar corpuscles after the protrusion of motionless rays, and forma- 



tion of a vacuole. 



e. Similar corpuscles completely decolourized and converted into slug- 



gish specimens of Actinophrys. 

 /. First stage in transformation of Actinophrys, some of which are 



converted into Amoeboe (^), and others into Monads {¥) with 



two flagella. 

 j. Enchelys-like organisms, probably derived from further development 



of some of Monads and Amoebce.
