any part of Australia, though North Queensland birds are also small. It 
seems certain that this subspecies will soon be extinct so that there will be no 
need for controversy as to its status. 
KaJcatoe galerita queenslandica (Mathews). North Queensland. 
The North Queensland subspecies is noticeably smaller than the typical 
subspecies. I named it from Cooktown, and birds from Cooktown to Cairns 
measure in the wing 325-335 mm. in the males, a female going less. These 
average very little less than the Victorian race, but have the bill noticeably 
smaller and not projecting or “ licmetiform.” Since the form was distinguished 
I have received a good series from Cape York and these absolutely confirm 
this race, as the wing measurement of males varies from 318-330 mm., and 
of females from 310-323 mm., the averages reading £ 323, $ 316 mm., thus 
inclining to the belief that the female was slightly less. I would again instance 
this as a case where averages do not show the truth, and I do not believe that 
there is any appreciable difference between the sexes in this species. As 
an item of interest the longest wing measurement for all Australia among 
sexed specimens is marked female. 
KaJcatoe galerita fitzroyi (Mathews). North-west Australia, Northern 
Territory. 
As indicated by Gould this race is smaller than the typical subspecies, 
and the average of the wing of specimens I have would be 324 mm., varying 
from 323 to 326 in the females and 323 in the male. This agrees very closely 
with the preceding, but I uphold the subspecies as I note that the yellow 
coloration of the crest, under wings and under tail is noticeably paler than that 
in the Queensland race. The bill of course is not “ licmetiform ” in character 
and is comparatively small. 
KaJcatoe galerita melvillensis (Mathews). Melville Island. 
We have here a well-marked island race, as the birds are as large, or 
larger, than the typical subspecies, though the mainland adjoining carries a 
race noticeably less. Thus males from Melville Island vary in the wing from 
351-355 mm., averaging 353 mm., while females vary from 335-357 mm., 
averaging 346 mm. It will be observed that there again the females 
average less than the males, but such seems fortuitous, as the largest bird 
is a female. 
It is not possible for me at this time to deal as completely with the extra 
limital forms, but it is certain more subspecies must be admitted than has 
hitherto been the case. Thus accurate workers must acknowledge that the 
Aru race is separable from the one living on Mysol and Salwatty, while to 
class all the mainland White Cockatoos as another subspecies clashes with 
the geography of New Guinea. When Rothschild and Hartert’s results are
