(No. 34,667.) First primary short, about two-fifths the 2d, which is about 

 equal to the 8th or 9th ; the 4th and 5th about equal and longest. (These

 brighter on the rump, becom- 

 ing brownish anteriorly, or 

 more truly olive ; the top and 

 sides of head, with nape, olive 

 brown. A broad stripe from 

 nostrils over and beyond eye

 it and eyelids quite pure

 post-ocular stripe like thQ head. Cheeks tinged with olive. Chin and throat 

 whitish ; rest of under parts yellow, deepest on sides and crissum. Sides of 

 breast tinged with brownish-olive. Quills and tail feathers brown, edged ex- 

 ternally with olive green, internally with pale yellow. No bands on the wines,
