SPOROZOA. 



more compact. Very rarely " rosettes," with merozoites, 

 found in the lung-smears. Female gametocyte oval, with a 

 compact oval nucleus situated in the middle and some granules 

 and rods of pigment irregularly scattered in the surrounding 

 area. Male gametocytes not found. Infected red cell 

 sometimes dehsemoglobinized, somewhat enlarged ; but does 

 not show dots of any kind. 



Eemarks. — The parasites were very scanty and were found 

 in the blood and lung-smears only. 



Habitat. — Blood and smears from the lung of the fish-otter, 

 Lutra lutra Linn. : Portfgtjese India, Nagoa.

brown. Immature schizonts and gametocytes also observed. 

 Infected red blood- corpuscles may be sHghtly enlarged. 

 Sporogony not known. 



Remarks. — Breinl (1912) described P. pteropi from the blood 

 of a flying fox, Pteropus gouldi Peters, in West Austraha. 

 Johnston (1913) and A. & M. Leger (1914) described P. pteropi 

 as a new species. Mackie (1914) also described a very similar 

 form from Pteropus medius Temm. {= Pteropus edwardsii 

 Horsfield), and gave it the name P. pteropi without knowing 

 that Breinl had already given the name to the West Austrahan 

 form. According to Wenyon the two are probably identical. 

 The parasite was also seen in the blood of the flying fox in 

 Ceylon, and Wenyon (1926) has drawn the figures from these 

 films. 



Habitat. — Blood of the flying fox, Pteropus medius Temm. 

 —P. edwardsii Horsfield) : India ; Ceylon.
