H If the flagellar border splits, the membrane doubtless divides also; but where the flagellum is a new formation the membrane will be too.
Nearer the flagellar end).
The small Trypanosomes resulting from either of these modes of division differ from typical adults by their stumpy, pyriform shape, the position of the kinetonucleus near the flagellar end of the body, and the absence, during the first part of their youth, of an undulating-membrane.
E - H shows the formation of the myonemes and the flagellar border (flagellum) of the undulating membrane, by means of a greatly elongated nuclear-spindle.
Flagellar border of undulating-membrane (3rd axial spindle).
