 of African frogs, fl.*-, Marginal flagellum of 

 the undulating membrane ; ft. 2 , free flagellum ; 

 m., myoneme-striations (it is doubtful whether 

 the granular streaks or the clear interspaces 

 correspond exactly to the actual myonemes); 

 n, kinetonucleus ; N, space in which 

 the trophonucleus lies, but, not being 

 stained, it is not clearly defined in 

 the preparation. After Minchin, magni-

 the same magnification.
