which I sought to identify on my return from the field. On com- 

 paring it with fall specimens from the mountains of Colorado it 

 was immediately seen to be a dusky grayish bird tinged with oliva- 

 ceous and therefore very markedly different from the cinnamon 

 rufous Colorado bird. It is also much smaller than the Colorado 

 bird and agrees in this respect with three other northern speci- 

 mens from White Pass, and Glacier Bay, Alaska, and Nahanna 

 Mountains, N. W. T., respectively. 



The name leticurus seems to be applicable to this small northern 

 form. The measurements given by Swainson indicate the smaller 

 bird and one of the specimens which he describes is said to be " in 

 the act of assuming its winter dress " and to have "the base of 

 the whole upper plumage blackish grey " which exactly describes 

 the Cook Inlet bird above referred to and could not possibly apply 

 to any of the Colorado birds. ''In summer plumage the two forms 

 are distinguishable only by ^ze.
