THE BIRDS OF AUSTRALIA. 
Australia. I found it common in the neighbourhood of the goldfields and 
on Nov., 1920, saw it in the timbered water courses near Dongara and 
Geraldton. 
c ‘ I also collected it in the wet large-timber country at Ellensbrook. 
The specimen I collected there is distinctly paler than are those I took in the 
goldfields. It seems probable that a pale race inhabits the S.W. corner of 
W.A. 
“ While the song or whistle of this species is very similar .to C. harmonica, 
it is decidedly less strong, the eastern species having the greater volume of 
sound.” 
As regards the scientific history of this species there is little to be 
written, as its range was supposed to be Western Australia alone. It was, 
however, found to be common in Eyre’s Peninsula, and in my “ Reference 
List ” in 1912 I admitted : 
Coliuricincla rufiventris rufiventris Gould. 
West Australia, Swan River District. 
Coliuricincla rufiventris whitei Mathews. 
“ Differs from C. r. rufiventris in its brown coloration above and below. 
Eyre’s Peninsula, S.A.” 
South Australia. 
I later added : 
Coliuricincla rufiventris murchisoni Mathews. 
“ Differs from C. r. rufiventris in having a brown back, not slate-blue ; 
the throat is brown, and the belly has no white. East Murchison, Westralia.” 
Mid-west Australia. 
These three were included in my 1913 “ List,” and I have since added 
Coliuricincla rufiventris carter i, from Albany, S.W. of West Australia. 
“ Differs from C. r. rufiventris Gould in being a darker shade above and 
the vent much more pronounced in colour. It is also smaller.
