 culmen 2-9, wing 10'8, tail 3'9, tarsus 3-25. 



Youiif/. Different from the adult, being everywhere thickly 

 streaked and spotted with buffy white ; crown of head and neck 

 streaked, the back, scapulars, and wing-coverts with large ovate 

 or triangular spots ; quills dusky blackish, spotted with white at 

 the ends and irregularly shaded with rufous; tail also rufous, 

 tipped with white and irregularly barred or mottled with dusky 

 blackish ; sides of face and under surface of body white, everywhere 

 streaked with dusky blackish ; a distinct white stripe along the 

 cheeks ; throat and abdomen white ; under wing-coverts and 

 axillaries streaked with blackish like the breast : " iris yellow " 

 (J". Gould). 



Young birds after the first moult are much duller than the old 

 ones, being perceptibly browner on the back, and everywhere 

 duller in colour, with the ends of the quills dusky and the inner 

 secondaries mottled with dusky. 



The two specimens from the Pelew Islands are smaller than the 

 majority of the Australian examples, and are more dusky in tint, 

 the inner web of the quills being dull chestnut. I do not see, 

 however, that they can be specificallv separated from the typical 

 bird.
