darker on the head ; the tail brownish, crossed with five bands of black¬ 
ish-brown, and ending with white; primaries brown; sides of the head 
and of the neck uniform bright rufous (not of a deep color) and without 
dark striae; chin and throat pale rufous white, unspotted; under plum¬ 
age white, with narrow transverse bars of pale rufous on the breast ; and 
on the abdomen, sides, and thighs with very faint narrow bars of pale 
rufous-brown, almost obsolete on the lower parts of the abdomen and 
thighs; under tail-coverts pure white; bill black, plumbeous at base; 
legs yellow. 
“Length, about 10£ inches; wing, G|; tail, 4£; tarsus, 1£.” 
Adult female .—“It is larger than the male and more distinctly barred 
on the breast, the thighs rather lightly so; it has the unspotted rufous 
cheeks, and the lower part of the abdomen is white, as in the male.” 
Young male. — . . . “ Umber-brown above, with the cheeks of a reddish- 
brown streaked with dusky; the breast blotched with light brown, and 
bars of darker brown on the abdomen ; lower part of the abdomen white, 
with faint brown transverse markings.” 
Young female. — . . . “ Pale umber-brown above, the sides of the head 
and neck having dusky streaks and showing scarcely any coloring of 
rufous; sagittate blotches on the breast of a pale rufous brown, with 
narrow transverse waving lines on the abdomen and thighs of a paler 
brown.” 
“ Another young female . . . has the sides of the head rufous-brown, 
with dark streaks, and the throat pale rufous; the markings on the 
lower parts darker and more clearly defined, the thighs more barred 
than in any of the others.” 
Mr. Lawrence remarks (l. c. p. 10):—“ In form, fringilloides is smaller 
and more slender than fuscus , but the clear rufous cheeks, nearly white 
under plumage, especially that of the thighs, are strongly in contrast 
with the rufous - br<$wn cheeks streaked with dark brown, and the 
strongly-marked rufous under plumage and thighs of fuscus. All speci¬ 
mens of the young under examination have the markings on their 
under plumage transverse, on the abdomen and thighs being waving 
and narrow ; w hereas in the young of fuscus these markings are longi¬ 
tudinal, large in size, and more extensively distributed; on the sides 
they are heart-shaped in form, and guttate on the abdomen and thighs.” 
Dr. Gundlach remarks (Lawrence, l. c., p. 11) that “the adult male 
and female have the bill black, with the base of a lead color; cere and 
feet yellow, or pale orange ; iris reddish-gray The bill in the young is 
black on the upper part to the extremity, with a bluish base ; cere and 
cheeks yellowish-green; iris pale orange-gray; feet yellow.” Accord¬ 
ing to the same gentleman, the fresh measurements were as follows :— 
Adult male. —Length, 0.278; extent, 0.508; tail, 0.135. Adult female . — 
Length, 0.326; extent, 0.618; tail, 0.155.
