BLACK-THROATED FLYEATER. 
albiventris , Machcerirhynchus flaviventer, Arses lorealis, Malurus amabilis , 
Sericornis minimus, and Rhipidura dry as. The nest is usually placed near 
the papery nest of a small yellow hornet or wasp, sometimes near that of the 
large hornet, and occasionally away from any hornet’s nest. The young birds 
have four peculiar head-plumes, which they have the power of erecting and 
quivering vigorously. When one looks into a nest these head-plumes are 
put into motion by the birds, and remind one of a number of caterpillars waving 
about. The gape of the young is a rich yellow colour. The Cuckoo, C. russata, 
also makes use of this species as a foster-parent. Nests were found from 
September to May, and, as usual with this genus, contained two eggs. This 
note was made from observations taken in a dry season. During the past 
season, 1912-13, three-egg clutches were more often found.” Then again : 
“ At the Claudie River it is usually found in the scrub, hunting about amongst 
the leaves and branchlets for insects. The nest, though pendent, is pear- 
shaped and compact, quite unlike the elongate structure of G. magnirostris. 
A few pairs were noted by Mr. McLellan on the Archer River.” 
North in the Records Austr. Mus., Vol. VII., 1909, p. 186, pi. lvh., gave 
an account of this nest-building habit and a photo of the nest adjacent to that 
of a wasp’s nest. This seems to be a common practice of all the species of this 
group in the tropics, but its usage is not well known yet. 
This beautiful well-marked species was described from Cape York, Queens- 
land and later a similar, but quite distinct, form was named by Ramsay from 
the Herbert River, Queensland. This was dismissed by European workers as 
representing the female only, the throat patch being Indistinct and ill defined. 
However, De Vis proved that all the birds from the latter locality showed this 
feature, and that it was a peculiarity which was constant and, therefore, 
Ramsay’s species must be recognised. 
As it was simply a matter of degree of depth of coloration I regarded 
them as subspecies and recently more specimens have shown the intermediates 
which I differentiated as : 
Pseudogerygone personata johnstoni. 
“ Differs from P. p. fiavida (Ramsay) in being yellower on the under- 
surface and more brownish-green above. Type from the Johnstone River, 
North Queensland.” 
Pseudogerygone personata watsoni. 
“ Differs from P. p. personata (Gould) in having the throat patch much 
less pronounced. Type from the Watson River, N. Queensland.” 
As the species is confined to North Queensland and the throat patch 
varies hi intensity as it goes south from Cape York, its New Guinea origin was 
indicated. Examination of extra-limital material showed its relations to be
