 the same host-species, in the form of the sporoblasts.

kinds of movements, viz., a bending movement and a screwing 

 movement, in which the organism turns rapidly on its long 

 axis and advances with the more pointed end forwards. This 

 anterior end of the body bears on either side a hyahne blade- 

 Uke structure or lamina. Schizogony is initiated at a very 

 early stage and there are two types of schizonts : (a) macro - 

 schizonts, releasing twenty to thirty macromerozoites, which
