THE BIRDS OF AUSTRALIA. 
I will always be a great upholder of subspecies, in their proper status, and a 
perusal of my work now in progress will show how I utilise them. They are of 
secondary importance in the study of bird systematics, but recently they were 
placed in the foreground. 
I have to thank, as usual, all my good friends for their assistance 
with notes and specimens. Captain S. A. White, Thomas Austin, Tom Carter, 
Dr. W. D. K. Macgillivray, H. L. White, Alexander H. Chisholm, and others. 
The finding of the female Atrichornis ( see p. 24) enables me to add under 
Adult female : — Differs from the male in having the under-surface uniform 
rufous-brown, lacking the grey throat and black breast-patches. It is also 
smaller. Eyes coffee-brown, bill dark horn, lower mandible fighter. Skin at 
base of bill whitish ; feet leaden-grey in the female ; dark horn in the male.* 
The Check List is to be bound up with Vol. VIII., so the Volume will 
contain over 430 pages and 82 life-size figures.
