Oocysts usually ovoid, but sometimes spherical, and possess 

 a definite micropyle closed by a cap. Four sporo blasts are 

 developed in the oocyst, and a residual body may or may not 

 be present. Sporocysts possess a micropyle at the more 

 pointed end ; a residual body is always left in the sporocyst. 



Dimensions. — Oocyst, ovoid 20-40 ^u, by 17-26 ^a; spherical 

 18jLt in diameter ; sporocysts ISfxhy Qfx 



Eemarks. — The parasite is said to cause progressive pernicious 

 anaemia that sooner or later ends fatally. 



Habitat. — Intestine of sheep : India (locahty not noted).

Various developmental stages occur either in the cells of 

 the epithehal fining of the gaU-bladder or attached to them, 

 or floating freely in the fluid in the gaU-bladder. Schizonts 

 rounded, oval, or irregular in shape and give rise to from 16 to 

 140 merozoites. Merozoites are elongate curved bodies, 

 with pointed extremities. Microgametocyte is a large ovoid 

 body. Microgametes simple, rod-shaped. Macrogametocyte 

 characterized by a crescentic mass of granules surrounding 

 its nucleus. Oocysts colourless, elfiptical. Four sporoblasts 

 develop as roundish masses, without the formation of any 

 residual body. Sporocysts ovoid, without a cap : each con- 

 sists of two valves, appfied to one another like two watch- 

 glasses, and contains two sporozoites, which are elongated 

 structures sfightly longer than the sporocyst, with their ends 

 coiled in. The sporocystal residue is represented by a mass 

 of granules lying in the middle. Development of the sporo -
