blue, the next on either side, green, the margins of their inner webs 
black, the apical half of the outer webs, blue, tipped with bluish- 
white ; the remainder of the feathers green at the base, margined 
with black on their inner webs, and changing into blue on their 
outer webs and bluish-white on the apical half of the feathers, 
the green decreasing and the blue and bluish- white increasing 
towards the lateral feathers, which are but slightly tinged with 
green at their base ; under surface of the two central tail feathers 
black, shaded with green on their outer and inner webs for two- 
thirds of their length, the next on either side black, the margins

feathers 8*45 inch ; bill from forehead O’ 9 inch ; from nostril 07 
inch; tarsus 0-8 inch ; mid-toe O’ 9 inch. 
Habitat. — Roeburne, North-west Australia. 
Type. — In Australian Museum, Sydney. 
Note . — When held in certain lights, the two central tail feathers 
show numerous bronze cross-bars. Another specimen has the 
apical half of the outermost secondaries tinged with blue, and the 
two central tail feathers tipped with black. 
Remarks. — Two specimens were obtained by Mr. E. H. Saunders 
at Karratha Station, thirty-six miles S.W. of Roeburne, North-west 
Australia, early in 1889, and were referred to by me at the Sep- 
tember meeting of the Linnean Society of New South Wales in 
the same year, as immature specimens of Platycercus %onarius i but 
upon a recent examination of a series of skins of the latter species 
in different stages of maturity, at present in the Reference Collec- 
tion, as well as those in the Macleayan Museum at the University, 
and Dobroyde Collection, I find that the specimens from North- 
west Australia are quite distinct. 
In the disposition of its markings P. Occident alls resembles 
P. zonarius , but it differs from that species in having light blue 
instead of dark blue cheeks ; in the greater extent of the con- 
spicuous lemon-yellow of the lower portion of the breast and the 
whole of the abdomen, and which extends as far as the vent , instead 
of the deep gamboge-yellow of the centre of the abdomen only; in 
the verditer-green of the chest, back, wings, scapulars and inter- 
scapular region, instead of dark green, and in the absence of the 
narrow black band immediately below the collar.
