species are those of Swainson, as cited, and of Audubon in Ornith. Biog. v., p. 296. 

 I am not without suspicion that tliis is the bird figured by Wilson, as above.

Hah. Florida, West Indies, and South America. 



Ohs. A species also considerably resembling r. olivacea, hut larger and with 

 the bill distinctly longer. It is easily distinguished by the narrow black lines 

 running downwards from the corners of the lower mandible. 



This is the largest of all the species yet discovered, and was first obtained within 

 the present limits of the United States, by Dr. A. L. Heermann, in Florida. It is 

 probably the bird alluded to by Mr. Gosse, in his delightful volume on the Birds 

 of Jamaica, though I can only judge by the measurements given by him which 

 are too large for V. olivaceus. Mr. Gosse appears though to have had access 

 to the plate of Audubon and possibly that of Wilson. He gives no detailed de- 

 scription. Nuttall, in Manuel i., p. 360, (1840,) says "the V. olivaceus has never 

 yet been found in those islands," (the West Indies,) but it does not appear to me to 

 be impossible at all that it may be, as Audubon met with it in Florida and Loui- 

 siana. (^Orn. Biog. II., p. 288.) 



4. Vireosylvia Jlavoviridis, nobis. Buff. PI. Enl. 558, fig 2 ? 



Form. Generally resembling that of V. altiloqua, but is rather smaller, the 

 wings and legs are shorter, and the latter much less robust, the bill is also slightly 

 more slender. 



Dimensions. Total length of skin from tip of bill to end of tail 5h inches, 

 wing 3 and 2-lOths, tail 2 and 2-lOth inches. 



Colors. Head above pale cinereous, superciliary stripes pale ashy-white, 

 not so distinctly defined as in V. altiloqiia. Entire plumage of the body above 

 fine yellowish olive, wings and tail brown with their feathers widely margined 

 externally with the same yellowish olive and internally with yellowish white. 

 Sides of the neck and of the body beneath, inferior wing and inferior tail coverts 

 fine greenish yellow, middle of the body beneath from the base of the bill to the 

 abdomen pure white. Upper mandible lead color, lower white. No black lines 

 from the base of the lower mandible, and general color of the body above much 

 more vivid than in V. altiloqua. Trides red. 



$ Rather smaller and colors paler. 



Kab. Panama, where it was obtained by Mr. John G. Bell, and San Juan de 

 Nicaragua, from whence it was sent to this Academy by Mr. A. de Barruel. 



Ohs. This is a very handsome species, much more brightly colored, and with- 

 out the black lines on the front of the neck which characterize the V. altiloqua. 

 Four specimens are in the collection of the Academy. 



Mr. Bell represents this bird as having been rather common near Panama in 

 May, 1849, and that in habits and song it much resembled the red-eye, (F. 

 olivaKea.'^
