BIOLOGY OF THE PROTOZOA 



Finally in flagellates with multiple nuclei (family Calonymphidae) , 

 in addition to a number of free blepharoplasts and parabasal bodies, 

 each nucleus is accompanied by a blepharoplast which gives rise

to three uniform flagella and one longer, band-formed flagellum, by 

 a parabasal body, and by a rhizoplast (axial strand, Fig. 63). 



Many of these aggregations of kinetic elements are sufficiently
