The larger sporonts are usually associated in syzygy ; the smaller 

 ones solitary. The infection is generally not heavy, but pretty 

 common. 



2. Gregarina minuta sp. nov. (Fig. 2). 



The larger sporonts are usually in association, the smaller ones 

 often solitary. 



Fig. 2. Gregarina minuta n. sp. 



a, A large syzygy with satellite lacking protomerite. A small syzygy. 

 c , A solitary sporont. All 360 x . 



Protomerite ovoid, sometimes more or less half-moon-shaped, 

 broader than long. It is not large, especially so in the satellite, in 

 which it is not infrequently hidden from view, being entirely imbedded 

 in the deutomerite of the primite. 



Deutomerite elongate, cylindrical, rounded posteriorly. Between 

 the two segments of the body there is usually a distinct constriction. 



Epicyte thin, rigid. Sarcocyte thin all over the body. Septal 

 region not thick. Endocyte not dense, almost clear in appearance. 



Nucleus large, spherical, usually situated near the middle of 

 deutomerite, clearly visible in living animals in both primite and 

 satellite. Karyosome single, large, spherical. 



Cyst small, spherical.
