LENGTH above five inches. The bill is brown, 

 the inside and edges yellow; eyes hazel; upper 

 parts of the plumage yellow, inclining to a pale 

 olive green ; the under pale yellow ; over each 

 eye there is a whitish streak, tinged with yel- 

 low, which in young birds is very distinct; the 

 wings and tail are dusky brown, with pale edges: 

 legs yellowish brown. 



There are three or four distinct species* of these, 



' The author was so fortunate as to procure specimens of this 

 and others, taken at the same time of the year, and had an oppor- 

 tunity of noticing the difference of their song. For these specimens, 

 as well as for many others, this work is indebted to the late Major 

 H. F. Gibson, of the 4th Dragoons.
