Fig. 83. Longitudinal section of part of one kinetodesmos of 

 Stentor polymorphus, showing origin of individual fibrils at kineto- 

 somes. X 24,000. From Randall and Jackson, 1958.

Fig. 85. Section of Euplotes patella showing several kinetosomes 

 and cilia of one cirrus at upper right, with bundle of attached rootlet 

 fibrils running toward bottom left. Note dense granules at bases 

 and half-way up fibrils of kinetosomes; outer and inner pellicular 

 membranes; cross-sectioned pellicular fibrils (arrows). X 24,000.
