obscured. In summer a rufous tinge diffuses itself over the entire bird, but more especially over the lores,
eyebrows, and under surface, leaving, however, the centre of the belly nearly white.”

head, and slight streaks of the same hue on the feathers of the back; under surface white, faintly tinged
with fulvous ; the feathers of the sides of the neck, the breast, and flanks with an oblong spot of blackish
brown in the centre; wing-coverts brownish black, the middle ones tipped with yellowish white, and the
greater broadly edged with olive; primaries brown, margined with olive ; central tail-feathers olive-brown,
external web of the outer feather on each side pale olive; the inner web brown at the base and along
three-fourths of the margin, the remainder white; the intermediate feathers brown, with olive margins ;
the one next the outermost on each side with an oblong spot of white at the tip of the inner web ; bill
