 show the chromatic bodies. The body is more or less circular 

 in transverse section and the surface is marked by about 

 sixteen longitudinal striations. Nucleus spherical or sub 

 spherical, situated in the broader anterior part of the body,

 gametocytes, show a somewhat flattened body, wdth the 

 anterior end drawn in but still differing in its appearance 

 from the rest of the body, and the posterior end is wider than
