Sp. Ch. — Upper parts and sides dark olive green. Ciown ash color. A narrow frontal band passing backwards on the cheeks 

 and ear coverts, and extending a little above the eye. Beneath bright yellow. Length, 4.75 ; wing, 2.55 ; tail, 2.40. 

 Hab. — West Indies and South America. Oregon? 



It is scarcely certain that the present species really belongs to the fauna of the United States. 

 Its occurrence in the West Indies (where it really belongs) and in Oregon, without being 

 found in any intermediate locality, would seem very improbable. Mr. Audubon received his 

 specimen (No. 2905 of the accompanying list) from Mr. Townsend who probably procured it 

 somewhere else than in the assigned locality. i 



This species is readily distinguishable from the Geothlypis trichas by its larger size, bright 

 yellow of the entire under parts, (without any brown,) and the ashy crown, without any lighter 

 space separating it from the black of the forehead. The tail is broad and much graduated ; 

 the lateral feathers .45 of an inch the shortest. The wings are much rounded ; the first quill 

 shorter than the sixth. 



List of specimens. 



* Nuttall states that Townsend 's specimen was taken near Port Vancouver, O. T., not in California, as given by Audubon.

Sp. Ch.— Wings but little longer than the tail, reaching but little beyond its base. Head and neck all round with throat and 

 fore part of breast ash gray, paler beneath. The feathers of the chin, throat, and fore breast in reality black, but with narrow 

 ashy margins, more or less concealing the black, except on the breast. Lores and region round the eye dusky, without any 

 trace of a pale ring. Upper parts and sides of the body clear olive green ; the under parts bright yellow. Tail feathers 

 uniform olive ; first primary, with the outer half of the outer web, nearly white. Female with the gray of the crown glossed 

 with olive ; the chin and throat paler centrally, and tinged with fulvous ; a dull whitish ring round the eye. Length, 5.50 

 inches ; wing, 3.45 ; tail, 2.25.
