THE BIRDS OF AUSTRALIA. 
geographical order the variation was diminished or emphasized and conse- 
quently subspecies were determinable. Three names were available but all 
these had been given to the same specimen. 
I separated four subspecies as follows : — 
“ Cacatoes roseicapilla, roseicapilla (Vieillot). Queensland ; New South 
Wales, South Australia. 
Cacatoes roseicapilla kuhli subsp. n. 
6 Differs from C. r. roseicapilla in its smaller size, and paler coloration 
above and below. Wing 255 m.’ Northern Territory. 
Cacatoes roseicapilla assimilis subsp. n. 
‘ Differs from C. r. roseicapilla in its paler coloration above and 
below, but larger than C. r. kuhli ; wing 262 mm.’ Mid- 
Westralia. 
Cacatoes roseicapilla derbyana subsp. n. 
c Differs from C. r. assimilis in its very light grey coloration above, 
, and its pale, scarcely pink, coloration below. A very distinct 
form.’ North-west Australia.” 
In my List of the Birds of Australia , published at the end of 1913, I 
maintained the above after re-considering my augmented collection. 
I have again reviewed the species and maintain the above but add 
another form. When the above was prepared I had no Victorian series, so 
that locality was missing from the range of the species. I have since received 
specimens and I find that the birds inhabiting the Mallee of Victoria and 
South and Central Australia constitute a recognisable race which I name 
EolopJms roseicapillus howei subsp. n. 
These differ from the typical dark New South Wales birds in being much 
lighter in coloration, the grey of the upper parts having a bluer shade while 
the under surface coloration is of a paler shade than that of E. r. kuhli. Type 
from between Claraville and Ruby Gay, Central Australia, and is a male 
collected by Captain S. A. White in the 12th September. 1913. In my 
collection. 
It may be noted that when Barnard reported upon the Rirds of the 
Brunnette Downs he used the name Cacatua derbyana and the vernacular 
Pallid Rose Cockatoo for the form there living, as he noted it was different 
from the typical form.
