Sp. Cu.—Above uniform olive green, with a tinge of yellow. Crown with two narrow streaks of black from the bill, enclosing 
a median and much broader one of brownish orange. 
Beneath white ; the breast, sides of the body, and a maxillary line 
streaked with black. The female and young of the year are not appreciably different. Length, 6.00; wing, 3.00; tail, 2.40. 
Hab.—Eastern North America to the Missouri. 
The sides of the head are olivaceous, paler than the back, with a superciliary band of the same 
color outside the black. The loral space and a ring round the eye are whitish, the latter with 
a little yellow. The feet and maxilla are yellow; the mandible brownish. The brownish orange 
of the crown is usually obscured by olivaceous tips to the feathers, sometimes to such an extent 
as to hide it almost entirely from view, (4719.) 
A specimen of this species (8387) from Independance is larger with longer wings than any 
others in the collection.
