appsirently also belong- here, being much darker than either aphrasta 
or (llajjJioi'ii. 
This is one of the dark races, particular!}^ in winter. In the deep 
3'ellow color of the throat and eyebrow cJirysolwnia is very uniform; 
in winter plumage the breast just below the black jugular crescent is 
frequently tinged, though never extensively, with the same. The 
feathers of the tibia, particularly those of the lower portion, are also 
often conspicuously yellow. The upper surface varies much in color, 
in some specimens being verj' dark, with back and cervix strongly 
contrasted; in others much lighter, the cervix more pinkish in shade, 
the back only inconspicuously streaked and showing a tendency toward 
complete obliteration of the line of demarcation between it and the 
cervix.
