THE HAEMATOZOA OF AUSTRALIAN BIRDS. 419 



halteridia were detected, though microfilariae were present 

 in one. 



Halteridium of Myzomela sanguineolenta (M. 746). In 

 one of four specimens of this bird, obtained at Eidsvold in 

 June, halteridia, as well as very long thin filarise and intra- 

 corpuscular trypanosomes, were present. The parasites 

 occupied the side and both ends of the host-cells and had 

 fairly abundant coarse grains of melanin. 



Halteridium of Ptilotis fusca (M. 769). A few halteridia, 

 together with intracorpuscular trypanosomes in two 

 instances, were present in three out of nine specimens of 

 this bird, obtained at Eidsvold in March, and in one bird 

 obtained in April. The parasites occupied a relatively 

 large area of the red cells. 



Halteridium of Ptilotis sonora (M. 772). A few halteridia 

 were present in the blood-cells of a specimen of this bird 

 obtained on the Murray Flats near Blanchetown, S.A., in 

 May. The parasites occupied one side and most of the ends 

 of the host-cells, and had a few coarse grains of melanin. 



Halteridium of Myzantha garrula (M. 804). Eight birds 

 from Queensland were examined — seven came from Eids- 

 vold and one from Gladstone. Halteridia were present in 

 three of the Eidsvold specimens, obtained in December (1) 

 and February (2). The February birds also had filarise. 



Halteridium of Myzantha flavigula (M. 806). In a bird 

 shot at Rowena, in the north of New South Wales, in 

 November 1910, halteridia were found. Melanin was 

 present as fairly large rods. 



Halteridium of Entomyza cyanotis (M. 813). In a bird 

 shot at Eidsvold, Q., in October by Dr. Bancroft, a few 

 halteridia were seen. This bird also showed 'intracorpus- 

 cular trypanosomes ' (elsewhere described in this paper) and 

 a small species of embryo filaria.
