Description. 



Bill nearly as long as the head ; upper parts generally rather clear olive-green; 

 head with four black stripes and three brownish-yellow ones, namely, a black one 

 on each side of the crown, and one from behind the eye (extending, in fact, a little

 with olivaceous on the sides ; tail unspotted. Female nearly similar. 



Length, five and fifty one-hundredths inches ; wing, three ; tail, two and thirty- 

 five one-hundredths inches.
