SANDERLTNG. 425 



the reel colour of the breeding- season had disappeared, but 

 the autumn moult having commenced, a few of the greyish- 

 white feathers of the winter plumage appeared intermixed 

 with the faded remains of the tints of summer. A bird 

 killed on the 25th of October had completed its winter 

 dress. 



A bird of the year in the plumage previous to its first 

 autumn moult, had the crown of the head, back, scapulars, 

 and wing-coverts, black, edged with yellowish-white ; a brown 

 streak in front of the eye ; nape, sides of the neck, and sides 

 of the breast, pale grey, with wavy streaks ; forehead, throat, 

 fore part of the neck, and all the under parts, pure white : 

 wings and tail as in the adult. 



A young bird in half-down, obtained at Grinnell Land 

 on the 8th August, 1876, had the upper parts darker, the 

 markings smaller, and of a warm bufi"- colour, as are also 

 the lower throat and sides of the neck. It is figured in 

 Mr. Dresser's 'Birds of Europe,' viii. pi. 559. 



Varieties of this species are rare, but Mr. C. M. Adamson 

 has recorded a white one, apparently a young bird of the 

 year, shot at Holy Island, Northumberland, on the 28th 

 August, 1879.
