against a grey (neutral) back. The general under-surface is also whiter. It 
is a nice question if the two are specifically distinct, unless the bird obtained 
in North Queensland be considered intermediate and finks up with the larger 
southern form.” Campbell then queried the selection of Port Essington, 
when Gould had written “ North-west Coast of Australia,” and I have 
pointed out that this is Gould's fault , not mine, as the birds are so labelled 
in Philadelphia. Campbell has since noted in connection with this particular 
form that “ Bynoe’ s specimens were obtained during the survey of the North- 
west Coast,” and that “ Grey’s specimen is labelled in the British Museum 
Catalogue ‘ N.W. Australia,’ ” and concludes “ That does not appear like 
‘ Port Essington, Northern Territory.’ ” 
It may be of interest to remind ornithologists in cases like this that 
history was being made when these birds were collected and that it was due 
to the surveys undertaken and accompanied by Sir George Grey and Bynoe 
that the ill-fated settlement of Port Essington was made. Consequently 
there can be little doubt that the specimens of C. argenteus did come from 
Port Essington, especially as it has not been found on the North-west Coast 
(at Wyndham or Derby for instance). Bynoe made a collection at Port 
Essington, see Gould, Handbook Birds Austr., Vol. I., p. 419, 1865.
