THE HAEMATOZOA OF AUSTRALIAN BIRDS. 427 



undulating membrane and a short free flagellum were also 

 present. The intracorpuscular phase in this bird occurred 

 as deep blue spherical bodies embayed in the nuclei of 

 red cells. The protoplasm was finely granular or alveolar 

 with an occasional small vacuole : the macronucleus 

 appeared as a pale purplish-red central mass : in one speci- 

 men, the macronucleus appeared as a purplish mass at the 

 side of the parasite, whilst near the centre, in a clear ring, 

 the micronucleus was distinct as a deep purple dot. The 

 nucleus of the host cell was stretched round the parasite, 

 extending from half way to beyond this. The protoplasm 

 of the host cell could be traced beyond the parasite and 

 host nucleus as a faint rim. Occasionally an earlier phase 

 or a male form of intracorpuscular body was seen embayed 

 similarly in a nucleus ; its tint was a pale blue with a pale 

 purplish central mass. 



In the April bird a single intracorpuscular body was seen. 

 Halteridia were present also in this bird and in the January 

 one, but were not seen in the May specimen. 



Intracorpuscular Trypanosomes of Sphecotheres maxil- 

 laris (M. 852). In two birds shot in April, a few typical 

 intracorpuscular bodies, like those found in Oriolus, were 

 seen. Micronuclei were not noticed. 



Intracorpuscular Trypanosomes of Corcorax melano- 

 rhampus (M. 883). In two specimens obtained at Eidsvold, 

 Q., in April, a few typical intracorpuscular trypanosomes 

 without centrosomes were seen, also one doubtful injured 

 free trypanosome. Filarise were present in both of these. 



Peculiar Bodies, Free and in the Leucocytes, in 

 the Blood op Microeca fascinans. 



In the large mononuclear cells of a specimen of this bird 

 obtained in May, in which halteridia but no intracorpuscular 

 trypanosomes were present, some small rounded bodies 

 were seen. Four cells were found thus affected in a few
