Abstract

1. In the intra-cellular stage the mitochondria occur as a few granules. When the parasite becomes freed into the alimentarycanal lumen the mitochondria actively divide in the cytoplasm and occur scattered or in concentrations in different regions of the cytoplasm. 2. The Golgi apparatus occurs as a semi-lunar body appearing pasted an to the nuclear membrane in the intra-cellular stage. When this divides into two the duplex structure becomes evident. When the parasite becomes freed into the alimentary canal lumen the Golgi bodies which are vesicular show the duplex structure. During division the Golgi body becomes dumb-bell shaped. The two knobs when they separate are semi-lunar and between the two runs the chromophobic part as a strand. One of the bodies thus formed becomes vesicular by a fusion of the chromophilic rim and the chromophobic part connecting the vesicle with the batonette seems to contract into the cup-like area before the batonette also becomes vesicular. Thus division of the Golgi body is a division of its chromophilic and chromophobic regions equally. 3. The duplex structure of the Golgi bodies is discussed and it is shown that the chromophobic part has nothing to do with the sphere. The chromophobic and chromophilic portions together form an entity and the idiosome and archoplasm are entirely different structures. The relation between the Golgi and central apparatus is merely topographical and hence it is difficult to accept Gatenby's suggestion that either the Golgi and the central apparatus were evolved side by side or the Golgi from the central apparatus in some way.
