WHITE-THROATED FLYEATER. 
Mr. J. W. Mellor has written me : “I have seen this little bird both in 
Queensland and in New South Wales ; in the latter State I met it at Ourimbah 
in the Gosford district ; it was in the subtropical growth in the deep gullies 
and kept to the thick foliage, where it was seeking out its insect food, upon 
w r hich it wholly subsists ; it was by no means plentiful.” 
Mr. T. P. Austin’s notes read : “ At Cobbora, New South Wales, this 
species arrives in the spring in fair numbers, when their peculiar lackadaisical 
song (which I find quite impossible to distinguish from that of E. culicivorus) 
is to be heard the whole day long from any favourable haunts, such as the 
smaller eucalyptus trees and saplings, where it gathers its food. They are 
very tame little birds, and I have had them often come within a few feet to 
inspect me. . . Of the many nests I have examined, they have mostly 
contained three eggs, sometimes only two to a clutch, and have all been 
during October and November. What appears strange to me is that I have 
never discovered a nest containing young birds.” 
Mr. J. P. Rogers wrote me: “Here in West Kimberley these birds are 
very numerous, more so nearer the coast than inland, although at Marngle 
Creek there were a good many. At Mungi I did not see any : apparently they 
do not migrate.” 
Mr. A. G. Campbell, who was the first to note this species in Victoria, 
observes : “ The male has a striking song. The birds feed actively among 
the gum-tree leaves, and often take insects on the wing.” 
Gould’s original four species of Psilopus included olivaceus and albogularis 
in this order : he later considered that the former was probably the immature 
of the latter and used the latter name. Until Witmer Stone re-examined the 
types it was doubtful whether the names did apply to the same thing or not, 
but he reported that they undoubtedly did, and consequently the former name 
should be used for the species. Diggles later described as a new species of 
Acanthiza a bird from Normanton, which proved to be a form of this species. 
Then a skin brought back by Elsey was recorded by Sharpe as G. ciner- 
ascens, a species described from Port Moresby, South-east New Guinea. When 
Hartert received better specimens from North-west Australia, he correctly 
regarded these as subspecies of G. albigularis , but wrongly continued 
Sharpe’s name. 
I separated these as G. a. rogersi, writing : “ Differs from G. a. albigularis 
in being paler above and much smaller in size. Av. wing G. a. albigularis 
60 mm. : that of G. a. rogersi 54 mm.” Later I diagnosed G. a. queenslandica 
as differing from G. a. albigularis in its smaller size, paler coloration above 
and lighter yellow below. 
When I recognised Diggle’s Acanthiza jlavigasta was referable to 
vol. vm.
