 " Sylvia tennessaei, Vieillot," Grat. 



Sp. Ch. — Top and sides of the head and nock ash gray; rest of upper parts olive green, brighte.'^t on the rump. Beneath 

 dull white, faintly tinged in places, especially on the sides, with yellowish olive. Eyelids and a stripe over the eye whitish ; a. 

 dusky line from the eye to the bill. Outer tail feather with a white spot along the inner edge near the tip. Female with the 

 ash of the head less conspicuous ; the under parts more tinged with olive yellow. Length, 4,50 ; wing, 2.75 ; tail, 1.85. 



llab. — Eastern United States to the Missouri. 



In this species the bill is small and quite acute. The wings are long, reaching beyond the 

 middle of the tail, which is sliglitly emarginate. The second and third quills are longest ; the 

 first but little shorter, and longer than the fourth. 



It is very seldom that specimens are found with the gray neck and crown, this l)eing gen- 

 erally, especially in winter dress, oC the same olive as the back, and the greenish yellow of the 

 under parts much more conspicuous and extended. In this dress it becomes very difficult to 

 distinguish it from autumnal specimens of H. celata. The under parts of the latter species are, 

 however, generally of a brighter yellow, cNpecially on the tail coverts, and the wing is consid- 

 erably shorter ; the superciliary stripe, too, is less distinct. 



Specimens from Pennsylvania appear to have the bill larger than more western ones. The 

 Sjlcia bicolor of Vieillot (Ois. Am, Sept. II, 1807, 32 ; pi. xc, bis) cannot belong to the Sylvia
