7. Genus Duboscqia, Perez. Each sporont develops into sixteen sporo- 



blasts each of which forms one spore. Parasitic in Termes lucifiigus. 



8. Genus Plistophora, Gurley (1923). Each sporont develops into more 



than 16 spores. Widely distributed parasites in copepods, insects 

 and fish. 



Family 2. Coccosporidse, Leger and Hesse (1922), emend Kudo (1924). 

 Spores spherical or sub-spherical. A single genus: 



9. Genus Coccospora, Leger and Hesse (1922), Kudo (1924). Parasites 



of oligochetes, insects and Crustacea. 



Family 3. Mrazekidse, Leger and Hesse (1922). Spores tubular or 

 elongate cylindrical (length more than five times the diameter). 



10. Genus Mrazekia, Leger and Hesse (1916). Spores straight-tubular; 



polar filament with rod-like base. Parasites of annelids, Crustacea 

 and insects.

 Diptera.

Order 3. Actinomyxida, Stolc. 



These are Cnidosporidia about which httle is known beyond the 

 process of sporulation. In its fully grown condition the entire 

 body may be interpreted as one pansporoblast which is surrounded 

 by a membrane, and wdiich usually produces eight spores, the mem- 

 branes of which are usually triradiate and drawn out into elaborate
