 of the body ashy-grey, finely vermiculated with darker grey ; 

 under wing-coverts ashy-grey ; axillaries white, freckled with

Adult Female. Differs from the male, the back being ashy- 

 brown, narrowly barred with rufous on the hind-neck and 

 mantle ; the dorsal feathers brown-edged with ashy-grey, these 

 edgings becoming whiter on the rump and upper tail-coverts ; 

 the scapulars with more rufous margins; wing-coverts ashy-grey, 

 margined with white, more broadly on the greater series ; the 

 bastard-wing, primary-coverts, and primaries as in the male ; 

 the secondaries dusky-brown, externally black and tipped with 

 white, but not showing a distinct speculum like the male; 

 inner secondaries velvety-black, edged with white on the outer 

 web, and separated from the black speculum by a line of white, 

 caused by the white outer web of a single inner secondary ; 

 tail ashy-brown, narrowly fringed with white ; crown of head 

 blackish, with small white bars, producing a thickly mottled 

 appearance ; lores, sides of face, and sides of throat fulvous, 

 dotted and spotted with blackish, throat slightly more rufous ; 

 remainder of the under surface pure white; the under tail- 

 coverts centred and barred with brown ; the sides of the chest 

 and of the body mottled with rufous. Total length, 16 inches; 

 wing, 9-6.

 they acquire their perfect livery. The younger birds with tl 

 speculum developed have often only half the wing-covei 

 white, and, judging by a specimen in the British Museui 

 killed in June at Kiukiang by Mr. Styan, I should say tl 

 until the second summer, the male retains a wing exactly lil 

 that of the old female. After the breeding-season, Mr.
