MlCROGAMETOCYTE ( $ ) MALE 

 CRESCENT 



1. The chromatin of the 

 nucleus occurs in an extensive 

 loose network, occupying the 

 greater portion of the parasite. 



2. Comparatively little 

 blue staining protoplasm. 



3. The pigment is scat- 

 tered. 



4. The shape is somewhat 

 kidney-shaped, shorter and 

 broader than in the $ . 



MACROGAMETE ( $ ) FEMALE 

 CRESCENT 



1. The chromatin occurs 

 in a compact mass more or less 

 centrally placed. 



2. Much more blue stain- 

 ing protoplasm. 



3. The pigment is con- 

 centrated into a ring around 

 the nucleus or heaped up into a 

 mass. 



4. Crescentic in shape, 

 longer and narrower than the 

 male. 



N.B. Gametes (crescents) may be but rarely found in the blood 

 of Europeans in the tropics (West Africa). 



2. Simple Tertian. The female gamete ( $ ) is 

 characterized by the possession of (i) much proto- 

 plasmic matter, staining deep blue with Romanowsky, 

 (2) little compact chromatin laterally placed, and

 (after Schaudinn) 



generally surrounded by a thin vacuolic area, (3) pig- 

 ment black in colour, and irregularly scattered over 

 the whole protoplasm (Fig. 10).
