have been neglected in this account. The trrm Aust raiia 

 is being used in a wide sense so as to include forms from 

 New Guinea and the adjacent islands such as Bismarck 

 Archipelago and the Aru Islands. 



Following the scientific name of each bird, there will be 

 found its number (indicated as M.) in Gregory Matthews' 1 

 Hand-list. As this ornithologist follows R. BowdlerSharpe's 

 Hand-list of Birds' in regard to genera and species, his list 

 may be considered as authoritative in regard to the correct 

 nomenclature of the birds in question. Then follows its 

 number (H.) in the second edition of Robert Hall's Key. 3 

 Thus the host in question may be readily placed. The 

 popular name given is in most cases taken from Hall's List. 

 The range of each bird may be found by consulting either 

 of these works, more especially the former. 



My thanks are due to my colleague at the Bureau, Dr. 

 J. Burton Cleland, who has very materially assisted me 

 with specimens of birds and helminths; to Mr. A. J. North, 

 Ornithologist to the Australian Museum, Sydney, who 

 has kindly identified many birds for me and has helped me 

 in regard to certain points in avian synonymy ; to Dr. F. 

 Tidswell, the Director of the Bureau ; to Mr. G. P. Darnell- 

 Smith, also of this Bureau ; and Mr. A. S. Le Souef, Curator 

 of the Royal Zoological Gardens, Sydney, and Mr. T. Steel, 

 for kindly sending me specimens. 



It may not be out of place to mention that this paper is 

 part of a scheme to more fully investigate our bird-life.
