Hsemogregarine showed extraordiaary activity. The free 

 form moved with a rapid swimming motion, and entered 

 a blood- corpuscle by simply piercing it, swimming round 

 between the nucleus and the corpuscle wall, and bursting the 

 corpuscle by curling and then suddenly straightening itself. 

 The process takes a few seconds. It also injures the corpuscles, 

 which it touches in passing, the corpuscle losing all its haemo- 

 globin immediately. The intra-corpuscular stage very closely 

 resembles the free form. 



Remarks. — Possibly the form examined by Robertson may 

 have been the same as H. pythonis (Billet). 



Habitat. — Blood of a snake, Python sp. : Ceylon.
