THE BIRDS OF AUSTRALIA. 
Five years later, Ogilvie-Grant (Ibis, 1910, p. 163) included both as 
species : thus : “ Platycercus icterotis. The series, which includes mostly 
immature birds exhibits various and somewhat puzzling stages of plumage ; 
as regards the colouring and pattern of the back specimen “ 1 ” approaches 
P. xanthogenys. 
Platycercus xanthogenys. This species was first described by Count 
Salvadori from a specimen in the British Museum which had formed part 
of the Gould collection, its origin being otherwise unknown. Subsequently 
Dr. Hartert recorded examples in the Tring Museum from Beaufort and 
Cranbrook, which places (according to the Editors of the Emu, VII., p. 117, 
1907) are in Western Australia. The discovery by Mr. Shortridge at Southern 
Cross is therefore of interest. It is very easily distinguished from P. icterotis 
(Kuhl) by the darker greenish grey (not sap-green) colour of the back and the 
margins of the innermost secondaries, while the middle pair of tail feathers are 
mostly dark purplish blue, instead of green.” 
Mr. Tom Carter observed (ibid. p. 655) : “ P. xanthogenys. It is exceed- 
ingly interesting to have this species confirmed from a definite locality. I 
have not seen Dr. Hartert’ s description of the specimens in the Tring Museum, 
and have often wondered why none had been obtained around Broome Hill, 
which is situated between Beaufort River and Cranbrook. P. icterotis is very 
common in that [this] district, and I have observed many birds with feathers 
on the back, margined broadly with red, and still more so on the rump and 
and upper tail-coverts.” In a letter quoted by North, Mr. Carter had added : 
“ They appear to correspond with the description of Platycercus xanthogenys , 
Salvadori, but to me they seem like well matured birds of P. icterotis .” 
In the preparation of my “ Reference List,” it was necessary to determine 
type localities for the forms and I therefore selected Sharks’ Bay, West 
Australia, as the type locality of P. icterotis. This locality was also fixed for 
Platycercus Stanley ii of Vigors, an admitted synonym of that name, no locality 
being known for that species also. For Platycercus xanthogenys Salvadori I 
recognised Point Cloates, West Australia. All these type fixations prove to be 
quite erroneous through a misapprehension of the range of the species and also 
of the facts. At the same time I distinguished two subspecies as follows : 
“ Platycercus icterotis salvadori subsp. n. 
Differs from P. i. icterotis in having less red on the mantle. 
Wilson’s Inlet, South West Australia. 
Platycercus icterotis whitlochi subsp. n. 
Differs from P. i. icterotis in its smaller size (wing 134 mm.) and much less blue 
on the wings, and the red on the head less brilliant. 
Lake Dundas, South-east of West Australia.”
