BANKSIAN COCKATOO. 
of the two species also vary considerably in the colouring of the bands across 
the tail-feathers, which in the C. banksii is pure scarlet, while the same part 
of the female of the present bird is mingled yellow and scarlet. It differs 
from the C. naso of Western Australia in having a larger bill than that 
species, and in the much greater length of the crest. 
“ Calyptorhynchus naso. The characters by which this species is dis- 
tinguished from the Calyptorliynchus macrorhynchus are a smaller bill and 
a shorter and more rounded crest. The bill is, moreover, inclined to be 
gibbous, like that of C. leachii, to which species it also offers a further alliance 
in its shorter contour and more rounded crest and short tail. The extent of 
range enjoyed by the Calyptorhynchus naso I have not been able to ascertain ; 
it appears to be most numerous in the colony of Swan River, where it inhabits 
all parts of the country. As might be expected, its general economy closely 
resembles that of the other members of the genus. Except in the breeding- 
season, when it pairs, it may often be observed in companies of from six to 
fifteen in number. It breeds in the holes of trees, where it deposits its snow- 
white eggs on the soft dead wood. They are generally placed in trees so 
difficult of access that even the natives dislike to climb them. Those given 
to Gilbert by the son of the colonial chaplain were taken by a native from 
a hole in a very high white gum, in the last week in October ; they are 
white, one inch and eight lines long by one inch and four lines broad. 
“ It flies slowly and heavily, and while on the wing utters a very harsh 
and grating cry, resembling the native name (Kar-rak). The stomach is 
membranaceous and capacious, and the food of those examined contained 
seeds of the Eucalypti , Banksiae , etc. The sexes differ considerably in the 
colour of the tail.” 
In 1878 Ramsay admitted three as above, but in 1891 he only allowed 
two, running all the western and northern birds together under the name 
C. stellatus, which I propose to discuss later. 
In the latter year, Salvadori’s account in the Cat. Birds Brit. Mus., 
Vol. XX., appeared and, there, consistent with his high reputation for care- 
fulness, that accurate worker admitted Calyptorhynchus banksii with range 
“ Eastern Australia, from Port Denison to New South Wales.” He then 
allowed C. 'macrorhynchus with range “ Northern Australia from Derby to 
Rockingham Bay,” but with this qualification : “ Whether this bird is truly 
distinct from C. banksi is a question which I am not able to decide, on account 
of the want of a sufficient number of specimens with the localities and sexes 
ascertained.” Then was added C. stellatus = C. naso Gould for Western 
Australia. Gould’s differential notes were reproduced with the observation: 
“ The specimens in the Museum are few in number, without having locality
