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. Inthe cases of the Sa/fator 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.
