338 MR.SHARPE ON THE ACCIPITRES OF AUSTRALIA. [Apr. 20, 
shaft-lines, the vent-feathers slightly washed with bright rufous, the 
under tail-coverts mottled with ashy frecklings ; under wing-coverts 
bright rufous, with broad central arrow-head markings of black, the 
lower series grey, barred with blackish brown, exactly resembling the 
inner lining of the quills. 
Mr. Gurney has pointed out to me an error that I made in 
adopting this species as the type of Kaup’s genus Urospizias, whereas 
Kaup intended his type of that genus to be the dstur radiatus of 
Temminck (nee Lath.)=A. approximans. I overlooked this by 
some mistake ; and as this Red Harrier Buzzard is really generically 
distinct, I adopt the name of Lrythrotriorchis, with which Mr. Gurney 
proposes to supplant Urospizias of my ‘ Catalogue.’

The receipt of aspecimen in Mr. White’s collection shows that the 
bird supposed by me to be the young (p. 327) is not really im- 
mature ; and I subjoin a description of a very young bird, which I 
now exhibit. 
Above purplish black, broadly tipped with tawny rufous, shading 
off into buff on the extreme margin; lower back and rump pale 
brown, broadly tipped with tawny rufous, especially on the under 
tail-coverts, which are barred and mottled with darker brown, being 
whitish at the base and for the greater part of the outer web ; tail 
slaty grey, tipped with buffy white and barred with six blackish 
bands, the subterminal one broader; upper wing-coverts purplish 
brown, broadly barred with tawny rufous, particularly broad on the 
outermost of the least series, which are mesially streaked with blackish 
brown, the greater coverts whitish near the base and barred with the 
same on the inner web; primary coverts uniform purplish brown, 
tipped with tawny ; quills purplish black, tipped like the coverts, the 
primaries inclining to slaty grey and barred with blackish on the 
inner webs; entire head, neck, and underparts bright tawny, the 
feathers centred with black streaks, narrower on the throat and chest, 
and disappearing on the abdomen and flanks; frontal feathers and 
chin indistinctly whitish ; ear-coverts more thickly streaked with 
blackish, giving them a dingy appearance; upper wing-coverts 
coloured like the breast, the lowest series ashy black, inclining 
to greyish white at base, and resembling the inner lining of the 
quills. 
NISAETUS MORPHNOIDES (Gould): Sharpe, Cat. i. p. 254. 
The bird figured by Mr. Gould and described by him as adult is 
most probably the young. At all events it is of the same plumage 
as the brown specimens of the Booted Eagle of Europe, which are 
generally shown to be immature. Mr. White has now sent me the 
adult bird, a skin of which he has very kindly presented to the 
Museum ; and he tells me that the brown birds are far rarer than the 
white-breasted ones. As might be expected, the present specimen 
much resembles an ordinary white-breasted N. pennatus ; but it has 
the unfailing character of the barred quill-lining by which I first
