SPOROZOA. 



the body in clusters or isolated granules. Male gametocytes 

 show the same form as the female, a Httle more irregular 

 in young stages ; nucleus in the form of an irregular spireme. 

 Pigment has the same appearance, but is more definitely 

 collected at the poles. When free the male gametocytes 

 are round, the cytoplasm showing a slight violet- bluish tone. 

 Infected cells are slightly hypertrophied. 



RemarTcs. — Hwrnoproteus has been previously recorded from 

 Coracia indica Linn, by Plimmer (1912, 1914) and from other 

 species of Coracia from other parts of the world, but none of 

 these appears to have been given a specific name. De Mello 

 rejects the idea that all Hsemoproteids from birds in general 

 are identical with H. daniUwskyi.

Fig. 107. — Hsemoproteus corvi, nom. nov. A, female gametocyte ; 

 B, male gametocyte ; G, so-called "Acton body," showing 

 schizogony. (After de Mello, de Sa, de Sousa, Dias, and 

 Noronha.) 



Young parasites small, lanceolate. Female gametocji^e 

 halter-shaped, stained blue by Leishman's stain. Nucleus 

 a large chromatic mass, stained deep red, situated usually 

 in the concavity of the halteridium, nearer one pole than the 

 other, and quite close to the nucleus of the infected corpuscle ; 

 pigment collected at one pole, but in the fully developed 

 gametocyte may occur at both poles. Male gametocyte ovoid 

 or halter-shaped, stained but Httle, almost yellowish ; nucleus 

 contains two or three chromatin granules, and is situated 

 near one pole, while the pigment is situated near the other.
