minutes search ; the bodies lay in the protoplasm, some- 

 times over the nucleus, and were from 3 to 9 in number. 

 They were small (about the size of human blood-platelets), 

 rounded, and seemed to lie in small vacuoles. They stained 

 reddish with Giemsa, and, in favourable specimens, the 

 staining showed about 7 chromatic dots arranged in a ring 

 with a clear space between the ring and the host protoplasm. 



In another bird obtained in April, several small purple 

 bodies, perhaps a further stage of the above, were seen in 

 a mononuclear cell. A larger phase, with bodies bluer, 

 was also seen, and groups of considerably larger free 

 spherical bodies of a pale bluish tint with a deep blue 

 thickened edge round one half were fairly numerous. The 

 last were quite possibly artefacts derived from the injured 

 nuclei of red cells, though we have not seen the same 

 appearance before. 



The blood films containing these various bodies were 

 rather poor and the parasitic nature of the bodies is ques- 

 tionable. We record what we have seen, however, so that 

 other investigators may be on the lookout for similar 

 appearances in other specimens of this bird. 



Bodies (Degenerated Red Corpuscles) from a Galah. 

 In a galah, Gacatua roseicapilla, which died in a Sydney 

 shop in April from a peculiar nervous affection to which 

 these birds are subject, some peculiar bodies were found 

 in the blood. The bodies, which were about as long as but 

 considerably narrower than the host red-cells, had elon- 

 gated somewhat pointed ends and were spindle-shaped. 

 Their protoplasm was bluish and somewhat granular, and 

 was occupied by one to three rounded spherical bodies, 

 showing in a clear area reddish chromatin masses. What 

 appeared to be a larger form was also noticed ; this was 

 oval, the protoplasm was reduced to a peripheral ring and
