Ccrchneis cinnainoniina. Adult male, P. U. O. C. 7954. About one-third natural size. 



Head: Forehead and region in front of eye and an indistinct eye-stripe 

 white; crown slate-blue, each feather striped by the black shaft-stripe;^ a 

 spot of deep cJiestmtt on the after part of tJie crown; a streak running 

 behind the ear-coverts and nearly joining a black well-defined nuchal band, 

 black; a well-defined black moustachial streak, black; ear-coverts chiefly 

 white, as are the sides of the face. 



Neck : Nuchal band defining crown black ; rest of upper neck bright 

 cinnamon ; chin and upper throat white, immaculate ; lower throat shaded 

 with cinnamon. 



Back : Bright cinnamon, decorated with blackish bars, varying much in 

 different birds, in the interscapular region and on the scapulars ; lower 

 back and upper tail-coverts immaculate bright cinnamon.^ 



1 The standard descriptions of C. cinnainoinma give the crown as having no chestnut marking 

 or spot ; the series from Patagonia shows at least some trace of cinnamon or chestnut in the crown 

 of each bird. 



2 These birds of both sexes, all taken in the southern part of their range, average larger than 

 birds from farther north, so that the difference is noticeable.
