behind the head ; there was a tail spot near the 

 posterior end. 

 (2). Smaller Form. — The parasites were considerably- 

 shorter and smaller, being from 0*06 mm. to 

 0-09 mm. in length, by 0'0045 mm. in width. The 

 anterior end was blunt ; the posterior gradually 

 slightly narrowed, and was also blunt. There was 

 no sheath and no noticeable cuticular striation. 

 The protoplasm of the body cells, stained with 

 Giemsa, assumed a deep-purple tint, and was 

 coarsely granular. There was a large, square, 

 clear space at the junction of the posterior and 

 middle thirds ; the V -space ( ?) was a little in front 

 of the centre. 

 The difference between the two forms after staining by 

 Giemsa's method was very striking, the larger assuming a pale- 

 blue colour, the smaller a deep purple. 



LIST OF AUSTRALIAN BIRDS EXAMINED FOR 

 H^EMATOZOA. 



The following is a list of 139 Australian birds, belonging 

 to 77 species, whose blood has been examined by us for 

 hsematozoa with negative results. 



In addition to the name of each species we have appended 

 its number in Matthew's ''Handlist of the Birds of Austral- 

 asia," published in "The Emu," vol. vii., 1908, supplement. 



We desire to acknowledge the courtesy of Mr. A. J. 

 North, of the Australian Museum, Sydney, who was good 

 enough to identfy those specimens about which we were 

 uncertain : —
