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. magnifica, 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 Dljihyllodes 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 (Jourii. 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.
