Belaf (1916) states that the endosome of Peranema is always alveolar in struc- ture, even in the interphase. Such an appearance seems to be de- pendent upon methods of fixation and staining, since it is evident in some of our preparations but not in others. Hartmann and Chagas (1910) have described a divided " centriole " in the endo- some of Pcranema during the prophase, but they did not trace the structure through mitosis and the cytological evidence presented.
