with the host's excreta and complete development in five or six 

 days if kept in a moist chamber. Gametes dissimilar ; male 

 gametes have one end pointed and female gametes are spherical. 

 During fertiUzation only the nucleus of the male gamete is 

 transferred to the female gamete. Gametocysts dehisce by 

 simple rupture and release oval sporocysts. A hyaliae mem- 

 brane, more prominent at one pole than the other, surrounds 

 each spore, and eight sporozoites are arranged superficially 

 along the long axis of the spore. 



Dimensions. — Trophozoites, young, attached, 43-150/i by 

 14-30 |Lt ; sporonts 800-1111 /t in length by 80-1 llju. in 

 breadth ; gametocysts 292-390 ju- by 263-375^ ; sporocysts 

 8|U. by 6//..
