THE BIRDS OF AUSTRALIA. 
“ Differs from A. c. castaneiventris in being darker above and in having 
the flanks very much paler. Jay Waterhole, MacDonnell Ranges, Central 
Australia.” 
A later consideration in connection with true A. pectoralis re-discovered 
by Captain White led me to the erroneous conclusion that North’s A. nigricincta 
was the adult of A. pectoralis, but also to the probably correct conclusion that 
A. castaneiventris was only the western form of A. leucopsis, a view published 
by Gibson some years before. 
Previously I had described two subspecies of A. leucopsis, a pallid form 
from Leigh’s Creek, South Australia, as A. 1. pallida, writing: “ Differs from 
typical A. leucopsis Gould in being much paler in colour, both above and 
below,” 
and Aphelocepliala leucopsis missa. 
“ Differs from A. 1. leucopsis in its browner coloration above and yellower 
below, and especially in its pale head. (Narandera) New South Wales.” 
At present only a few subspecies are admitted in comparison with the 
number indicated. 
Aphelocepliala leucopsis leucopsis (Gould), 
South Australia, limits of range unknown. 
Aphelocepliala leucopsis missa Mathews, 
New South Wales, Northern Victoria. 
Aphelocepliala leucopsis pallida Mathews, 
Leigh’s Creek, Interior of South Australia, 
Aphelocepliala leucopsis whitei Mathew's. 
MacDonnell Ranges, Central Australia. 
Aphelocepliala leucopsis castaneiventris Milligan. 
Mid-west Australia. 
Aphelocephala leucopsis minilya Mathews.
