Mr. Thomas Carter on some 
or he would not have supposed that his is the first record 
of the occurrence of the Bare-eyed Cockatoo in this State. 
It is the common Cockatoo of the North-west, and was 
recorded as occurring there twenty-three years ago : see Proc. 
Boy. Soc. Yict. vol. iii. p. 4 ( Campbell ) ; 4 Emu/ vol. i. p. 25 
(Campbell) ; f Emu/ vol. iii. p. 171 (Car'ter) ; 4 Emu/ vol. ii. 
p. 62 {Hall) ; 4 Halts Key/ p. 62; 4 Emu/ vol. iv. p. 38 
(. Kilgour ); Nov. Zool. xii. p. 211 ( Hartert ). Bather curiously 
Mr. Mathews in his 4 Handlist ’ has not given West Australia 
as one of the States where it occurs. C. gymnopis seems to 
be very close to C. sanguinea. 
38. Circus assimilis Jard. & Selby. 
Mr. Shortridge says: 44 The Allied Harrier is probably less 
numerous than C. gouldi in the south-west/” If it occurs 
at all in the south-west it must he very rarely, as I have 
never yet seen one in that part, but I found that it was 
plentiful in the north-west ( 4 Emu/ iii. p. 31). 
39. PlOTUS NOViE-HOLLANDIiE Gould. 
The Darter is certainly seldom seen in the west or south¬ 
west districts. During my twenty-four years’ residence in 
West Australia only two occurrences have come under my 
notice, one at Point Cloates, the other on the Pallenup Biver 
in the extreme south. 
40. Nettion gibberiprons S. Mull. 
It seems very curious that there is still so much doubt as 
to whether Nettion gibberifrons and N. castaneum are two 
distinct species or not. My experience is that N. gibberifrons 
is a freshwater Duck. I have seen great numbers both in 
the north-west and south-west, as it is a common species, 
and, if the green head and neck are ever assumed, the birds 
must breed freely in immature plumage. I have seen scores 
of birds on swamps and pools around which were many nests, 
and have shot many male birds, undoubtedly breeding, that 
had no trace of a green head or neck, but have seen only one 
place where N. castaneum occurs, namely, in a mangrove 
creek (sea-water) near the North-West Cape many miles from
