Sp. Ch. — Bill, froin rictus, about the length of the skuU. Above olive brown, with a shade of green ; beneath pale sulphur 

 yellow, brightest on the abdomen. Region about the base of the lower mandible, and a superciliary line from the base of the 

 bill to the nape, brownish yellow. A dusky line from the bill through the eye ; chin, and throat finely spotted. All the 

 remaining under parts and sides of the body, except the abdomen, and including the under tail coverts, conspicuously and thickly 

 streaked with olivaceous brown, almost black on the breast. Length, 6.15 ; wing, 3.12 ; tail, 2.40. Bill, from rictus, .64. 



Hab. — Eastern United States to the Missouri, and south to Guatemala, perhaps to Brazil. 



In this species the second and third quills are about equal, and a little longer than the first, 

 which exceeds the fourth. The tail is slightly rounded, the feathers acuminate-acute. The 

 feathers of the chin and throat have each a small triangular spot, the middle of the abdomen 

 being the only immaculate region. 



In nearly all specimens there is a trace of a median light stripe on the crown, visible at the 

 base of the bill ; sometimes this being more or less distinctly traceable half way along the crown.
