Bangs, Birds of San Miguel Island. 



29 



Color. — Upper parts grayish hair-brown, forehead not darker than 

 back, the long feathers of crown slightly darker in the middle part ; a 

 concealed white crown patch — small, but present and of about the same 

 size in both sexes ; rather narrow wing-bars, and edgings of primaries, 

 secondaries and tertials soiled yellowish white ; throat dull grayish white; 

 breast, sides and flanks pale, dull olivaceous ; belly and under tail-coverts 

 pale yellow ; lining of wing buff-yellow. 



Measurements. 



Remarks. — As no Ehenia of this style has been recorded from 

 Panama, it is rather strange to find a form so close to E. sororia 

 inhabiting San Miguel Island. I fancy that in fresh plumage the 

 color differences between the two forms would be more marked ; 

 as it is they show well in series. The new form is grayer above 

 and the contrast between head and back is less than in E. sororia. 

 E. sordidata has also a smaller white crown patch, and less white 

 in the wings, while the size and shape of bill and the length of 

 wing, tail and tarsus are noticeably different in the two forms. 



E. sordidata was not an uncommon bird on San Miguel, fre- 

 quenting low brush. Its breeding season was well advanced, but 

 Mr. Brown did not notice any young about during his stay on the 

 island. 



Our series of E. sororia from the Santa Marta region of Colom- 

 bia is so extensive that I have been able to compare specimens 

 killed on exactly the same dates and in precisely corresponding 

 plumage with the series from San Miguel Island of the new form.
