Tue characters given by Mr. Ridgway for the separation of 7. Suscescens salicicola from T. fuscescens, 
in the last edition of his ‘Manual,’ are as follows :— 
T. fuscescens. T. fuscescens salicicola. 
Above light tawny-brown. Above russet-olive. 
Chest creamy-buff, with narrow markings of Chest very pale buff, with broader markings 
brown, scarcely darker than upper parts. of darker brown. 
Length, 6:45-7:75 inches. Length, 6:90-7:90 inches. 
Wing, 3:75-4:15. Wing, 8:80-4:25. 
Tail, 2:70-3:30. Tail, 2°95--3°40. 
Culmen, 0:52—0:60. Culmen, 0:55-0:60, 
Tarsus, 1:05-1:25. Tarsus, 1:15-1:28. 
Eggs, 0:85 x 0:67. Eggs, 0:85 x 0:66. 
Hab. E. United States and British Provinces, Hab. Rocky Mountains, east (casually 2) 
breeding from about 40? north to during migrations, to Minnesota, Illinois, 
Manitoba, Ontario, Anticosti, and New- &c. 
foundland. 
In the British Museum are several specimens of T. salicicola from the Henshaw Collection, which 
have been identified by Mr. Ridgway himself, and I have therefore been able to form a judgment on 
the value of this race. As to the measurements of 7. fuscescens and T. salicicola, it will be seen 
from the dimensions given by Mr. Ridgway that they overlap, although 7. salicicola appears to be a 
slightly larger bird, as a rule. 
Taking the Henshaw specimens as typical, I can only say that, when they are compared with a 
series of undoubted 7. fuscescens, the variation in tone between the more rufous T. fuscescens and 
the more olive T. salicicola is so gradual that it seems impossible to draw any hard-and-fast line 
between them. Тһе darker specimens likewise resemble T. ustulatus in winter plumage, if it should 
happen that a careless preparation of the skin has obliterated the distinctive orbital ring of the latter. 
I may mention that intermediate specimens, which it has puzzled me to determine as to whether 
they are 7. fuscescens or T. salicicola, come from Michigan, Corpus Christi, Texas, and Camacusa 
in British Guiana. The Texan bird I refer to T. salicicola, and the others to 7 Juscescens.
