wing, 13-8; tail, 8'75 ; tarsus 2*0; central rectrices extending 

 %'7 inches beyond the lateral ones." 



*' young (Flamborough Head).— Head, neck, flanks, and back 

 dark brown, barred and mottled with dirty white ; crown and 

 sides of the head less marked with white ; abdomen white ; 

 crissum and under tail-coverts white, slightly barred with dark 

 brown; wings and tail as in the adult, but the central rectrices 

 extend only a little beyond the lateral ones. - " 



" Obs. — An old bird from Labrador, shot in the summer 

 season, has the yellow on the neck brighter than in the bird 

 above described ; the back is darker, and has no white mark- 

 ings on the forepart ; the band on the breast has almost disap- 

 peared ; and the crissum and under tail-coverts are deep uni- 

 form brown. Another nearly adult young male, obtained in 

 Leadenhall Market in the flesh, has the upper parts with 

 scarcely any white markings, but the hind neck is dark brown, 

 the forepart of the neck is white, slightly mottled with black- 

 ish brown ; and the breast and flanks are profusely marked 

 ■with that colour ; the rest of the underparts being, as in the 

 adult, above described ; the sides of the neck are washed with, 

 yellow, and the central rectrices are quite as much elongated 

 as in any specimen I have seen. A young bird from Torbay 

 has the underparts much whiter than in the young bird 

 above described, the breast and flanks being only slightly 

 marked with dark brown.'''
