Adult in whiter plumage. Apparently not to be distinguished 

 from that of A. maritima. 



Adult male in summer plumage. Similar to A. maritima, but 

 much more of a bright chestnut above, and with the white edging 

 to the baso of the inner primaries rather more marked; the band 

 on the fore-neck and chest much more broken up than in A. mari- 

 tima and is of a sandy colour when present, but it is sometimes 

 entirely absent, the fore-neck and chest being white with patches 

 of dusky black and narrow streaks of the same colour, there being a 

 black patch of greater or less extent on the sides of the upper 

 breast, in which respect the species much resembles A. ptUocnemis : 

 " base of bill dark greenish yellow, the outer two-thirds of the bill 

 black or very dark horn-colour ; feet dark greenish yellow to light 

 .olive; iris hazel" (E. W. Nelson). Total length 7'5 inches, 

 culmen l'l, wing 5, tail 1'95, tarsus 0'9.
