PREFACE 
T HIS, the end of Volume X., sees the close of my work in sight, that is to 
say, all the manuscript is prepared. This volume contains 123 figures, 
and 520 pages, of which 56 are taken up with the Check List, part n. 
(which is to be bound up at the beginning of the volume), bringing us up to the 
end of Volume IX. In this List I have brought part I. up to date, so that all 
the available literature is together in these pages, thus making it a useful book 
of reference. 
I have also prepared a Bibliography of Australian Ornithology, which I 
will publish later on. 
My correspondence with my fellow workers on the Royal Australasian 
Ornithologists’ Union Check List Committee goes far to show how close we 
are in general agreement, and I feel sure that the few remaining points will 
soon be satisfactorily settled. We shall then have an up-to-date and useful 
List on which to work. 
I am glad to record that Mr. H. L. White has been describing the nests, 
and eggs for some time and will continue to do so until the work is finished. 
I have to thank also all those who have contributed notes ; their names, 
are mentioned in the body of the work. I hope all who are interested will 
send me over any fresh piece of information that may be found. 
It is satisfactory to note that at a meeting of the Committee of the British 
Ornithologists’ Union on Nomenclature many of the corrections put forward 
in the Austral Avian Record were accepted, and it was decided that a larger 
number of genera should be used.
