THE HAEMATOZOA OF AUSTRALIAN BIR])S. 425 



Intracorpuscular forms were found in the films from 

 Anellobia chrysoptera from which we had previously 

 described the free form. We had overlooked the presence 

 of this phase. 



Free and Intracorpuscular Trypanosomes of Entornyza 

 cyanotis (M. 813). Both of these forms were present in 

 two blue-faced honeyeaters obtained at Eidsvold in April. 

 In one bird the trypanosomes were very narrow, in the 

 other they were broad, approaching those of Micrceca 

 fascinans and Pardalotus melanocephaliis. 



Bird 1. — The free trypanosomes were very narrow, with 

 a sharp-pointed posterior end and a similar anterior end. 

 The body was vacuolated with a few deep blue granules : 

 the macronucleus was near the centre, and the micro- 

 nucleus near the posterior end. The flagellum and undu- 

 lating membrane were not recognisable. Intracorpuscular 

 bodies, similar to those to be described in Oriolus Sagit- 

 tarius, were present. In some of these parasites were a 

 number (a dozen or so) of scattered small deep bluish gran- 

 ules. One early form was seen in a red cell; it was oval, pale 

 blue compared with the whitish host protoplasm, and lay to 

 one side of the host nucleus, being as yet not embayed. It 

 had a reddish elongated macronucleus, and two dark blue 

 dots. Some pale, irregularly oval free forms were also 

 seen, as if they had escaped from their host-cells. One of 

 these was pale blue and slightly vacuolated ; it had central 

 purplish nuclear fragments, and at one end a broad deep 

 purple dot resembling a micronucleus. 



Bird 2. — This bird showed much broader trypanosomes 

 than the previous bird, approaching those of Pardalotus 

 melanocephalus, though not quite so broad. The posterior 

 end was broad, narrowing however rapidly at the extreme 

 end : the parasite narrowed rapidly anteriorly. The body 

 was alveolar-looking and deep blue, being of the same tint
