In the presegmenting forms the pigment has not yet 

 condensed into a single block, and the distribution of 

 the chromatin masses is still irregular. In fresh pre- 

 parations the typical < daisy ' forms can be clearly 

 seen (Fig. 8). 



GAMETES 



Gametes are sexual parasites. They completely 

 fill the cell, and are distinguished from adult asexual 

 forms (Schizonts) by (i) their larger size, (2) by more 

 abundant pigment, (3) by the fact that there is only 

 one fairly large chromatin mass, whereas in an asexual 

 form of nearly equal size the chromatin has already

begun to divide into several portions (presegmenting 

 stage). The different staining reactions of male and 

 female are practically identical for all species. The $

 staining red, while the ? , being the nutritive cell, 

 contains much protoplasmic matter staining deep 

 blue.
