THE BIEDS OF AUSTRALIA. 
A. J. Campbell described in the Emu, Vol. X., Jan. 21, 1911, a “New 
Goshawk ” with the remarks : “ This large and handsome new Goshawk 
is the second of the genus found in Australia, the other being the Red 
Goshawk {Erythrotriorchis radiatus), and is closety allied to the Marquis 
Doria Goshawk {E. dorice),* found in New Guinea, but from which the 
Australian bird differs chiefly by its lighter coloration, the absence of 
dark spots on the under tail-coverts, and by the very distinct and uniform- 
coloured (rufous) thighs (tibia).” * The footnote with regard to E. dorim 
reads : “Of Salvadori and D’Albertis. For flgures see Gould-Sharpe’s 
Birds of New Guinea, Vol. I., pi. 2, concerning which Dr. Sharpe wrote: 
The original specimen came from Hall Bay;, in south-eastern New Guinea. 
There is the bird which forms the principal flgure in the plate, and which 
we consider to be immature. The second specimen flgured in the plate 
is apparently a fully adult bird, and was obtained by Mr. Goldie on the 
Astrolabe Mountains, in south-eastern New Guinea. We believe it to be 
an adult male, and the type to be an immature female, notwithstanding 
some discrepancies in the proportions of the quiUs and tail-feathers exhibited 
by the two specimens. If we are correct in thus assuming the relation 
of these two individuals, then it is evident that the genus Megatriorchis 
is the same as the Australian genus Erythrotriorchis, of which E. radiatus 
is the representative species on the latter continent. A larger number of 
specimens is, however, requisite to settle the point satisfactorily.’ ” 
The “ discrepancies in the proportions of the quills and tail-feathers ” 
which Dr. Sharpe refers to is so great in my opinion, that the two birds 
discussed are abundantly distinct generically, and even Rothschild and 
Hartert have now admitted this. 
The plumage described by Campbell was not, however, even new, as, 
though North consistently wrote “ female like male but larger, ’ and 
described the male as rufous below, when Sharpe introduced the genus 
Erythrotriorchis he described in detail a bird agreeing with Campbell’s 
description. 
When Hill gave his field-notes about the new bird in the same place 
{Emu, Vol. X., p. 266), he wrote : 
“ Erythrotriorchis radiatus (Red Goshawk). A single specimen was 
secured. 
“ Erythrotriorchis rufotibia (Red-legged Goshawk). 
“ I saw four only of these new and fine Goshawks. On 1/5/10 a pair 
took possession of the nest referred to under Hieracidea orientalis, to which 
they added a few sticks and a lining of green cajuput leaves. They were
