granular, non-pigmented. Intermediate forms 

 occur between this and the next developmental 

 stage. 



(ii) Vermicule forms, also endoglobular, 

 but after examining a fresh specimen of blood 

 for some time, free forms are seen thirty to 

 forty M long and three to four ^^. broad. These 

 are actively motile, and constrictions can . be 

 seen travelling down their length during the 

 motion. Young forms and reproductive forms 

 are not seen in the circulation. These are 

 found in the liver. The reproductive forms are 

 at first endoglobular, but later free. They occur 

 as 



(iii) Ovoid forms, ten to sixteen m long 

 by four to six fj- broad, shewing as many as 

 six nuclei (chromatin masses). The protoplasm 

 finally segments and there is formed 



(iv) An actively amoeboid young form.

The spores that are found in the kidneys 

 of tortoises belong, according to Laveran, not 

 to the haemogregarine at all, but are those of
