Plate VIII. Electron micrographs of flagella of some phyto- 

 flagellates. 



(a) Part of a flagellum of Ochromonas showing the mastigo- 

 nemes which carry one or more fine filaments at their ends. 

 Some of the fine flimmer filaments are also visible. From 

 Pitelka and Schooley (1955). x 27,000. 



{b) The tip of a flagellum of Micromonas squamata showing 

 hairs and scales attached to and detached from the flagellum. 

 From Manton and Parke (1960). 22,000. 



(c) Section through the whole body of Chromulina pusilla, 

 including a longitudinal section through the flagellum. The 

 short basal part of the flagellum contains the full 9-plus-2 

 bundle of fibrils, while the thin whiplash tip contains only the 

 two central fibrils. From Manton (1959). x 26,000.
