darker on the head ; the tail brownish, crossed with five bauds of black-

 on the abdomen, sides, and thighs with very faint narrow bars of pale 

 rufous-brown, almost obsolete on the lower ])arts of the abdomen and 

 thighs; under tail-coverts pure white; bill black, jilumbeous 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 maJe. — ..." Dmber-browu 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 alnlomen 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 {I. 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- brown 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 ; whereas 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, I. 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 j^ellow." 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.
