Oocysts almost spherical, sometimes oval. The mature 

 oocyst contains four sporocysts, each containing two sporo- 

 zoites, and does not show any micropyle. Sporocysts show 

 no cap. 



Dimensions. — Oocysts from 16-20 /u, by 14-18 /x.

Bemarks. — ^Knowles and Das-Gupta (1935) remark that the 

 form may be Eimeria raillieti Leger, but it was not possible 

 for them to make certain as they were unable to obtain 

 Leger's paper in India, nor could it be procured even in 

 London. This was due to the reference having been wrongly 

 cited by Wenyon. Coccidium raillieti was originally described 

 by Leger (C. R. Soc. Biol, xi, i (1899), pp. 309-11) from 

 Anguis fragilis Linn., and an abstract of the paper is given 

 in Wiegmann's ' Archiv ' (1904, pt. 3, pp. 115-16). The oocysts 

 ofE. knowlesi correspond to those of ^. raillieti in size, but those 

 of the latter are oval and show a small button-like protuber- 

 ance at one pole. As, however, the oocysts in E. knowlesi 

 are sometimes oval, and the size-range is not markedly 

 different from that of E. flaviviridis ( = " species B " of 

 Knowles and Das-Gupta, 1935), it is not certain that it is 

 a distinct species. 



Habitat. — Gut-contents oi Hem,idactylus Haviviridis (Riippell) : 

 Bengal, Calcutta. 



113. Eimeria koormse Das-Gupta. 



'fEimeria koormse, Das-Gupta, 1938, p. 155. 



Oocyst spherical, thick- walled, possessing a pseudo-micropyle 

 when mature ; without oocystal residuum. Sporoblasts 

 spindle-shaped ; sporocystal residuum present. 



Dimensions. — Oocysts 14 /a in diameter ; sporoblasts 10 /a by 

 4-5 /i.
