A large series of speeimens from the nortliern parts of the United 

 States shows considerable variations in color, etc. In all, of course, 

 the rump and tail are rufous, in decided contrast with the rest of tho 

 upper ))arts. The shade of color here varies considerahly, however: 

 generally it is of reddish olive, sonietimes as bright and of tlie same 

 shade as in T.fuscescens (as in 7591, Washington), t5;ongh generally 

 a little less intense. In two specimens only does the back have tho 

 olive rather than reddish shade predominant (28,22.5, Washington ; 

 29,649, Maine), as in T. swm/ifionii and nanus. These s])ecimens are 

 almost as small as nanus, but have the large bill and fulvous tinge 

 of sides and crissum of pallasii. In many specimens there are vestiges 

 of the lighter spots on the ends of the wing coverts. 



The under parts do not vary mr?h, although sometimes the tingo 

 of pale buff across the breast is more decided ; sometimes nearly 

 wanting. The size is pretty constant ; the wing rarely exceeds .3.75, 

 ill 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 audubotv', as Prof. Sumichrast has sent a specimen referable 

 rather to the latter variety. . .„ '_Z' ,^;i . '_
