TWO NEW BIRDS FROM SAN MIGUEL ISLAND, 

 BAY OF PANAMA. 



BY OUTRAM BANGS. 



The accession of better material, and a more careful study and 

 comparison of the birds collected on San Miguel Island, Bay of 

 Panama, by Mr. W. W. Brown, Jr., in the spring of 1900, have 

 led me to describe as new several species that at first I referred to 

 mainland birds. Even after the two which I now name — the 

 Vireo, which I formerly called Vireo chivi agilis, and the ant wren, 

 which I referred to Drymophila intermedia? — there still remain 

 undescribed three or four species whose identity with their main- 

 land representatives I greatly question. The birds were taken 

 late in the spring and some are in worn plumage, and I was unable 

 to find mainland examples in corresponding condition for compar- 

 ison. In the cases of the Saltator and the Ornithion the differences 

 seem too great to be accounted for by abrasion or fading, and I 

 think both these will prove to be island forms, requiring names. 



I have now studied material which warrants me in naming the 

 following two species. 



Formicivora 2 alticincta 8 sp. nov. 



Type, from San Miguel Island, Bay of Panama, <J adult, no. 4940, coll. of 

 E. A. and O. Bangs, collected April 30, 1900, by W. W. Brown, Jr.
