THE BIRDS OF AUSTRALIA. 
Regarding C. sanguined , Salvadori remarked : “ This species is easily 
distinguished from the preceding one by the shape and colour of the naked 
skin round the eyes.” Two birds were catalogued “ a $ ad. sk. Northern 
Australia, Dec. 14. Gould Coll. (Type of species), b. Ad. sk. Port 
Essington. Capt. Chambers.” 
C. goffini was localised as from Tenimber Islands. 
This conclusion was accepted as authoritative, but that it was not 
conclusive was readily remarked. Thus Campbell in his Nests and Eggs in 
1901 recorded Cacatua gymnopis with the distribution : “ Interiors of Queens- 
land, New South Wales, and South Australia,” remarking, however “ Although 
I have given a somewhat general distribution for the Bare-eyed Cockatoo, 
the only actual place I know where it exists is the region of the Barrier Range, 
on the borders of New South Wales and South Australia. But, according 
to Dr. Sharpe, it was the species found by Captain Sturt, the explorer, in 
immense flocks at Depot Creek, Central Australia.” As range of Cacatua 
sanguined Campbell noted : “ Northern Territory, Queensland, New South 
Wales, South, West(?) and North-west Australia.” 
North, in the Austr. Mus. Spec. Cat., No. 1, Vol. III., 1911, only 
admitted Cacatua sanguinea , ranking Cacatua gymnopis as synonymous, and 
explaining : “ Were it not that those eminent authorities, Dr. P. L. Sclater, 
late Secretary of the Zoological Society, London, and Count Salvadori, 
Director of the Zoological Museum, Turin, Italy, agree in declaring that the 
naked skin around the eye of Cacatua sanguinea Gould is white, I should 
have long ago sunk Cacatua gymnopis Sclater into a synonym of C. sanguinea. 
In his folio edition of the Birds of Australia Gould in referring to C. sanguinea 
remarks : “ With the exception of a specimen brought home by Captain 
Chambers, R.N., and another in the collection of Mr. Bankier, my own 
specimens are all that I have ever seen ; the whole of these were collected 
at Port Essington.” The old settlement at Port Essington was long ago 
abandoned in favour of Port Darwin, consequently it is seldom visited by 
collectors, in fact I know of no one collecting there since the late Mr. Alexander 
Morton did on behalf of the Trustees of the Australian Museum in 1870. 
The Northern Territory of South Australia is not, however, the terra incognita 
of Gould’s day, principally owing to the opening up of the country for 
pastoral purposes, and by prospecting parties in search of minerals, and the 
same may be said of North-western Australia, which Gould includes in the 
habitat of Cacatua sanguinea. Dr. Sclater described C. gymnopis from a 
living bird, and gives the habitat as South Australia ; he also examined in 
the British Museum the skins obtained by the late Captain Charles Sturt in 
South Australia and refers them to C. gymnopis. I have examined a large
