Hab. Nova Guinea (Horseshoe range). 
An immature male, but differing from D. chrysoptera in 
such a way that it is not possible to ascribe the peculiar 
characters to its stage of life. The colour of the wings is 
much more brilliant than in D. chrysoptera; the nasal 
plumes are longer; the back and rump are still more of a 
reddish brown; the belly is not violaceous, but like that of 
D. maynifica, and tinged with greenish on the sides; the 
breast-shield is rather grass-green than bluish green; the 
inner webs of the wing-feathers beneath more reddish than in 
D. chrysoptera. The stage of the development of the tail is 
interesting ; one of the two elongated middle tail-feathers has 
on both sides broad webs of a brownish colour (the broadest 
part of the whole feather measures 9 millim. across), with a 
central stripe of a metallic reddish violet, while the other 
has already acquired the narrow shape and bluish-green 
metallic colour of the adult. The great length of the re¬ 
maining tail-feathers may perhaps be explained by the fact 
that the female Diphyllodes has usually a longer tail than 
the male. It may be objected that it is possible that the 
immature form of this Diphyllodes may be more brilliant than 
the adult; but on the other hand a young male of D. magni- 
fica, almost in the same stage as the preceding, does not 
differ in the colour of the wings from the adult bird. 
17. Amblyornis subalaris, Sharpe. 
Sharpe described in 1884 (Journ. Linn. Soc., Zool. xvii. 
p. 408) only the female of this species. The male possesses 
a deep orange-red erectile hood: it is otherwise like the 
female which Sharpe describes, but altogether rather more 
olivaceous, and has bright shaft-stripes on the throat; the 
reddish orange-coloured hood is bordered on the sides with 
dark brown, and has dark tips on some of its middle feathers; 
the front is dark as in the female. The immature male has 
more black on the head. The bill is considerably smaller 
than in A. inornata.
