The Committee is greatly indebted to the following institutions and 
private persons for the loan of valuable specimens or literature which 
materially assisted the Committee in the preparation of the list, 
namely : — 
The Queensland Museum (per favour of Mr. Heber A. Longman, 
F.L.S.). 
The Australian Museum, Sydney (per favour of Dr. Chas. 
Anderson, F.G.S.). 
The National Museum, Melbourne, which includes the “ H. L. 
White Collection ” (per favour of Mr. J. A. Kershaw, F.E.S.). 
The South Australian Museum (per favour of Mr. Edgar R. 
Waite, F.L.S.). 
The Western Australian Museum (per favour of Mr. L. Glauert, 
F.G.S.). 
The Tasmanian Museum (per favour of Mr. Clive Lord, F.L.S.). 
The Royal Zoological and Acclimatization Society of Victoria 
(Zoological Gardens, Melbourne) per favour of Mr. A. Wilkie, 
Director. 
The Dominion Museum, Wellington New Zealand (per favour of 
Mr. W. R, B. Oliver, F.L.S.). 
Mr. Edwin Ashby, F.L.S., South Australia. 
Mr. J. W. Mellor, E.A.O.U., South Australia.

Particular thanks are due to Messrs. Angus and Robertson, pub¬ 
lishers, of Sydney, for typing and duplicating several progress lists for 
circulation for comment and criticism. 
Mr. J. Sutton, R.A.O.U., Hon. Assistant Ornithologist, Museum, 
Adelaide, rendered much appreciated assistance* with the proof-reading. 
Though much delayed, the list has not suffered. Steady work has 
been done in many directions. Mr. Mathews has completed his great 
and monumental work —The Birds of Austr olid — publication of the 
parts of the last volume of which is well in hand. As a member of the 
Checklist Committee, Mr. Mathews assisted greatly by much valuable 
correspondence and suggestion, as well as by his published lists and 
works. The authors of Australian Bird. Biographies have completed 
the examination of material for that proposed work. Specimens of 
certain purely Australian groups have been gathered and examined as 
never before, and the results have been incorporated. The leading 
ornithologists in each State of the Commonwealth have worked through 
draft lists, and have submitted suggestions and comments. Some have 
provided expert revisions of groups in which they were especially 
interested. 
Thus the delays have proved a blessing in disguise, for the Second 
Edition of the Checklist now contains the results of these various in¬ 
vestigations, and should prove acceptable to all. 
Great and constant increases in printing costs threatened to render 
impossible the publication of the “ Official Checklist of the Birds of 
Australia” (Second Edition). The convener, in order to reduce its size 
as much as possible, undertook to abbreviate to the full, so as to save 
all printing possible. To give even one line more to each species 
meant at least twenty pages added to the list, and an expenditure of
