The hybrid is slightly nearer coronata than to auduhoni. 

 The streaking of the back is apparently the same in amount. 

 The yellow of the crown is of a slightly lighter shade than in 

 either coronata or auduhoni, and its area is about the same, 

 though it is not so "concealed" as in coronata. The patch 

 of yellow on the rump is much the same as in either species, 

 although it is of a slightly lighter shade. Wings present a con- 

 dition clearly intermediate. In the hybrid the greater wing 

 coverts are not so broadly tipped with white as in coronata. 

 They differ from coronata, however, in being broadly edged with 

 white (no. 6012 has greater coverts very narrowly edged with 

 grayish brown). The middle coverts are on the average more 

 broadly tipped with white in the hybrid than in coronata, and 

 are edged with white. Some allowance must be made for the 

 fact that the hybrid is in plumage which is a little more worn 

 than that of no. 6012. This means that in the exactly compar- 

 able stage, the tippings and edgings would probably be very 

 definitely broader, and more extensive than in coronata. At any 

 rate it is apparent that the intermediate is in this respect nearer 

 coronata. The tail in no. 8687 is black, edged with bluish-gray 

 as in auduhoni. The white areas on the inner vanes of the rec- 

 trices are less in extent than in either 6012 or 8682. They 

 decrease in size from the outermost rectrix to the third, and are 

 practically lacking on the fourth. There is a faint indication of 

 white on the inner vane of the fourth rectrix on the left side. 

 In this respect the bird is not intermediate, but is like coronata. 

 A small white patch is apparent above the auricular region. 

 This is all that remains of the supra-auricular streak of coronata. 

 The bird has also a spot of white on the upper and on the lower 

 eyelid, like auduhoni. Thus in the reduction of the supra- 

 auricular stripe the intermediate character of the bird is again 

 shown. 



Suborbital and auricular regions are almost exactly inter- 

 mediate in color between coronata and auduhoni, being very 

 much blacker than the latter, but having nevertheless a distinct 

 blue-gray tinge. Loral region distinctly black, like coronata. 



The coloration of tlie malar region, chin and throat also, is
