 larva of Ephemera vulgata; spores 6.5^ by 4^. 



Order 4 Helicosporidia Kudo 



This order has been created to include the interesting organism, 

 Helicosporidium, observed by Keilin. Although quite peculiar in the 

 structure of its spore, the organism seems to be best placed in the 

 Cnidosporidia. 



The minute spore is composed of a thin membrane of one piece 

 and of three uninucleate sporoplasms, around which is coiled a long 

 thick filament. Young trophozoites are found in the host tissues or 

 body cavity. They undergo schizogony, at the end of which uninu-
