no centrosomes could be identified. Among our material one 

 finds all stages from cells like that in PI. 21, figs. 16, 17, to 

 corps en Id a r i 1 1 e t stages, one of which is depicted in PI. 21 , 

 fig. 18. This is a group of agametes or daughter individuals 

 produced by division of a trophozoite, and now ready to break 

 away into its component parts. Each merozoite has a nucleus 

 with an excentric nucleolus (n) which is always turned away 

 from the Golgi apparatus (g) : no exception to this rule has 

 been found to occur. The Golgi apparatus is either formed of 

 several little crescents together making a little granule, or it is 

 elongate. 



In PI. 21, fig. 20, is a large trophozoite with a completely 

 scattered Golgi apparatus (g), which may be seen to lie among 

 other granules (y) whose nature we do not care to examine 

 in this paper. Whether this is an individual of Eimeria or 

 Adelea we are not sure. Many trophozoites of the Lithobius 

 parasites have completely scattered Golgi bodies. 



Occasionally one finds schizonts in which some body like the 

 Golgi apparatus (PI. 21, fig. 15, gx) lies in the centre of the cell, 

 and appears to be taking no part in dictyokinesis. This is rare. 



? AND O^ GaMETOCYTES. 



In PL 21, figs. 19 and 21, are two cells which we can positively 

 identify as ? gametocytes — the o^ gametocyte rests upon them. 

 The Golgi apparatus of the ? gametocyte is much like that of 

 the trophozoites already described in PI. 21, figs. 11, 12, and 13 : 

 in some cases it is much more scattered. In the o^ gametocyte 

 we never found at this association stage a juxta-nuclear and 

 discrete apparatus as in the merozoites in PI. 21, fig. 18. Even 

 in preparations where the Golgi apparatus of the $ gametocyte 

 was beautifully marked as clear black rings and crescents on 

 a yellowish or grey background, the cx^ gametocyte was found 

 only to contain a few black granules (gx) generally stuck in its 

 periphery and of doubtful nature. While we cannot positively 

 identify a Golgi apparatus in the o" gametocyte at this stage, 

 the small granules which are present, and which might represent
