Lower parts as in the adult, but feathers of the breast and sides with 
faint longitudinal stripes of dilute brown, these wider and more rufous 
on the sides. 
Among the adult females before us, four in number, there is but slight 
variation to be noticed, three of them being quite alike, while the re¬ 
maining one, a specimen from San Gerouimo, Vera Paz, Guatemala 
(No. 2272, Mus. Salv. and Godin.), differs in having the lower parts 
quite extensively tinged witli ochraceous, especially on the breast and 
sides, while the anterior portions are destitute of the usual dusky shaft- 
streaks.
