portant differences are to be found in the slenderer, much more acfctely 
pointed bill, with its decidedly concave lateral outlines, and the different cha- 
racter of the nasal plumuli. The toes are much shorter, the lateral unequal, 
and the tail feathers broader and more rounded. 
Aegiothus of Cabanis (Mus. Hein. 1851, 161,) is based upon the Fringilla 
Unarm of Linnaeus ; and supersedes Acanthis of Bonaparte (Consp. Av. 150,) 
which though used in connection with the present genus, is pre-occupied for 
another group. 
Aegiothus euscesceks Coues, Nov. sp. — Dusky Red Poll. 
A. Aegiotho linario paululum minor , rostro fusco magno, robusto plumuVs brevibus 
sparsisque ; superioribus partibus fuscis, vix luteo striatis ; alis cauddque vix 
albido marginatis, lateribus distinct & nec confluents fusco-striatis. Mas nupt. 
temp . uropygio rosaceo, pectore carmesino. Long. 5.25 pollices ; ala 2.90 poll. 
Sp. Ch. Bill large, very stout, the culmen and gonys slightly convex • 
Nasal plumuli very short and scant, barely covering the nostrils. Wings very 
long, pointed; first primary usually longest, second nearly, sometimes quite 
equal to it, third and fourth successively a little shorter. Tarsus about equal 
to middle toe a$d claw. Inner lateral toe but very little longer than the 
outer, its claw reaching scarcely beyond the basal third of the middle claw. 
Tail of moderate length, deeply forked. Male , adult. — Bill dusky except at 
base below. Frontlet,’ space between eye and bill, and gular patch, dull sooty 
brownish black. Entire upper parts deep dusky or chocolate brown, the edges 
of the feathers scarcely lighter. Rump whitish, tinged with rosy, thickly 
streaked with dusky. Wings, wing-coverts, and tail, deep dusky, very nar- 
rowly margined and tipped with dull whitish. Throat, breast and sides for 
some; distance bright rosy, or carmine. Sides thickly marked with narrow, 
sharply defined streaks of chocolate brown. Rest of under parts white. 
Female adult. — Rather smaller than the male ; rump but slightly tinged with 
rosy, and few or no traces of the carmine on the breast, which is dull white 
streaked with dusky. Other parts as in the male. 
Length 5.25 inches, extent 9.00, wing 2.90, tail 2.30. Bill above .35. 
Tarsus .55 ; middle toe with claw .55 ; inner lateral .38. 
Habitat. — Northern and Eastern North America. Fort Resolution, (Kenni- 
cott.) Labrador, (Coues.) 
The essential features in which this species differs from the A. linaria, are 
those given in the diagnosis. The most striking peculiarity of form, as there 
stated, lies in the bill, which in size and proportions more resembles that of 
Leucosticte than Aegiothus. The nasal plumuli are much shorter and more 
sparse. The other proportions are as in A. linaria, hut the size is somewhat 
less. The colors are very different ; the upper parts of A. fuscescens being so 
dark and so obsoletely streaked as to seem almost uniform, which appearance 
is further heightened by the very narrow light edging to the wings and tail, 
which is reduced to a minimum. The sides are very thickly, but at the same 
time very distinctly, streaked with narrow sharply defined lines of deep choco- 
late brown. These streaks in A. linaria are less numerous, illy defined and 
more or less confluent. The carmine on the breast of full plujnaged males 
appears to be deeper than is usual in A. .linaria, while at the same time the 
rump is less rosy. 
This interesting bird, though by no means so common as the Tit-lark or 
White-crowned Sparrow, is yet abundant along the coast of Labrador, where 
apparently it replaces the allied Chrysomitris tristis, its southern representative. 
It is a remarkably unsuspicious and familiar species, showing no signs of fear 
even when very closely approached. It frequents almost exclusively; the 
scrubby juniper which grows every where in open places, in thick, almost im- 
penetrable patches. I do not think that I ever observed it in more densely
