(2) Genus Eleutheroschizon, Brasil. 
Schizogony extracellular. Sexual reproduction unknown. The 
general form of the trophozoite (multinucleate schizont) and its manner 
of attachment to the intestinal epithelium of the host recalls Opliryo- 
cystis. The trophozoite possesses a chromatic cap. 
One species only known at present.

2. Family Schizoeystidae, Leger and Duboscq. 
Trophozoites cylindrical, elongate or vermiform, with an anterior 
clearer region. Monocystid. Schizogony extracellular, with nuclear 
multiplication during growth. 
Two genera : Schizocystis, Siedleckia. 
(1) Genus Schizocystis, Leger. 
Trophozoites vermiform, affixed to the epithelium of the host by the 
anterior, clear extremity. Gametes isogamous, which, after conjugation, 
produce numerous octozoic spores. 
One species only known.
