A large series of specimens from the northern parts of the United 
States shows considerable variations in color, ete. In all, of course, 
the rump and tail are rufous, in decided contrast with the rest of the 
upper parts. The shade of color here varies considerably, however: 
generally it is of reddish olive, sometimes as bright and of the same 
shade as in 7’ fuscescens (as in 7591, Washington), though generally 
a little less intense. In two specimens only does the back have the 
olive rather than reddish shade predominant (28,225, Washington ; 
29,649, Maine), asin 7. swainsonii and nanus. These specimens are 
almost as small as nanus, but have the large bill and fulvous tinge 
of sides and crissum of pallasiz?. In many specimens there are vestiges 
of the lighter spots on the ends of the wing coverts. 
The under parts do not vary much, although sometimes the tinge 
of pale buff across the breast is more decided; sometimes nearly 
wanting. The size is pretty constant; the wing rarely exceeds 3.75, 
in one case only (2,092, Carlisle) measuring 3.85; in half the speci- 
mens it is about .20 less. The bill, too, is pretty constantly .40 
from tip to nostril. The tarsi measure about 1.15. 
A young bird has all the feathers of the head, back, and wing 
coverts streaked centrally with drop-shaped spots of rusty yellowish. 
I have seen no specimen of this bird from south of the limits of the 
United States. Mr. Sclater quotes one from Orizaba; but it may 
be the auduboni, as Prof. Sumichrast has sent a specimen referable 
rather to the latter variety.
