110 Count T. Salvador! on 



Comparing the Javan and New-Guinea bii'ds together, 

 what strikes one immediately is that the New-Guinea bird 

 is much darker, having the black spaces between the reddish 

 or light bars much wider. Also Mr. Biittikofer, to whom I 

 have applied for his opinion, after having compared, the spe- 

 cimens in the Leyden Museum, writes, insisting on the 

 blackish bars on the upper and lower surface being broader 

 in the New-Guinea bird, and giving to it a darker ap- 

 pearance. 



Another striking difference is in the fore neck, where the 

 dark bands are more arched, giving a scale-like appearance 

 in the New-Guinea bird, while in the Javan one the bands 

 are straighter and more regularly transverse. 



Besides the above differences there are also minor ones : — 



1st. The black line from the eye to the base of the bill is 

 wider in the New-Guinea bird. 



2nd. The light bands on the underparts are much Avhiter 

 in the New-Guinea bird. 



3rd. The breast along the middle is whiter in the New- 

 Guinea bird than in the Javan one. 



4th. The remiges, especially the primaries, in the New- 

 Guinea bird are blacker, with only a few reddish spots towards 

 the tip o£ the outer web, while in the Javan bird all the 

 remiges are more spotted with reddish on the outer web. 



5th. The primary-coverts are less spotted with reddish 

 colour in the New-Guinea than in the Javan bird. 



6th. Also the under wing-coverts are blacker and less 

 banded in the New-Guinea bird. 



7th. The tail is much the same in both birds, only darker 

 in the New-Guinea one. 



I cannot find that there is much diflerence in the propor- 

 tions of the remiges, which, in both specimens of the New- 

 Guinea birds and in one from Java before me, are as fol- 

 lows : — the first a little shorter than the second, the third 

 very little longer than the second. 



To my eyes and in my judgment the two birds are per- 

 fectly distinct. I add the synonymy of the two species and a 

 diagnostic description of both.
