BIRDS FRINGILLIDAE PEUCAEA CASSINII. 
485 
Sp. Ch. — Feathers of the upper parts rather dark brownish red or chestnut, margined with bluish ash, which almost forms a 
median stripe on the crown. Interscapular region and upper tail coverts with the feathers becoming browner in the centre. 
An indistinct ashy superciliary stripe (yellowish anteriorly ?) Under parts pale yellow brownish, tinged with ashy on the sides, 
and with darker brownish across the upper part of the breast. A faint maxillary dusky line. A few obsolete small spots across 
the breast. Edge of wing yellow ; lesser coverts tinged with greenish. 
Length, 6.25; wing, 2.30; tail, 2.78. 
Hab. — Georgia. 
The female does not differ, except in the smaller size. Specimens, probably not quite mature, 
have the breast and sides distinctly streaked with dark brown. The maxillary dark line is very 
distinct.

PEUCAEA CASSINII, Baird. 
Zonotrichia cassinii, Woodhouse, Pr. A. N. Sc. Ph. VI, April 1852, 60. (San Antonio.) 
Passerculus cassinii, Woodhouse, Sitgreaves' Rep. Zuiii and Colorado, 1853, 85 ; Birds, pi. iv. 
(Apparently related to Zonotrichia hotter i, Sclater, Pr. Zool. Soc. 1857, 214, Orizaba?) 
Sp. Ch. — Similar to P. aestivalis, but paler ; wings and tail longer. Above light chestnut, all the feathers margined and 
tipped with bluish gray. Interscapular and crown feathers with a narrow streak of brown. Beneath white, tinged with ash 
across the breast, and with brown towards the tail. An obsolete light superciliary, and narrow dusky maxillary stripe. Tail 
feathers obsoletely blotched with bluish white at the end . Bend of wing yellow ; lesser coverts tinged with greenish yellow. 
Length, 6 inches ; wing, 2.65; tail, 2.75. 
Hab. — San Antonio, Texas, to Los Nogales, Sonora. 
This species has a considerable resemblance to P. aestivalis, but differs in some appreciable 
points. The brown of the upper parts is paler, and the ashy edging to the feathers appears 
rather more extensive. The dark brown blotches on the back are of much less extent, being 
confined to a mere streak along the shaft, widening a little at the end, instead of occupying 
nearly all the feather. The upper tail coverts have a distinct subterminal black bar, and are 
tipped with bluish white ; the tertiaries are margined all round with white, much lighter than 
in aestivalis. The middle tail feathers are dusky in the centre, with obsolete dentations of the 
same color on either side. This I have not noticed in the other species. The sides of the head
