RUFOUS-EARED BLACK-CAP. 83 



from which the accompanying figure was drawn is 

 probably a female, since it has no spurious quill, 

 and the hack is not only mixed with grey, hut has 

 those black detached spots seen in the females of 

 PC Guianensis, Braziliensis, and other species ; but 

 it is our belief that the male possesses the rufous on 

 the sides of the head even brighter than the female, 

 and will possibly exhibit also the spurious quill so 

 common in the more typical species. The rufous 

 colour of the sides of the head spreads over the ears 

 and forms a line above the eyes, where it is united 

 to the other side of the head by a narrow line in 

 front. The top of the head is deep black, which 

 colour becomes broken into spots on the nape, neck, 

 and interscapulars ; the remaining upper plumage 

 s cinereous-grey, but those feathers which are near- 

 est the blank of the wings are pure cinereous, edged 

 with white ; the outer covers of the wings, the quills, 

 md the tail, are deep black ; the bill and the feet 

 ire bluish-black. The second and third quills are 

 nearly equal, and are the longest ; while the inner 

 margins of all, and the inner wing-covers, are pure 

 ivhite. All the under parts are white, tinged with 

 yellowish.
