brush, where they remained out of sight for the most part, an4 there 

 were neither songs nor call notes to draw attention to their presence. 

 At Sergief Island one specimen referable to this subspecies was taken, 

 on August 27. 



In all, fourteen specimens were collected (nos. 40093-40106), as 

 follows: Doch-da-on Creek, one adult male, one juvenal male; Flood 

 Glacier, one adult female, one juvenal male, two juvenal females, one 

 juvenal, sex undetermined; Great Glacier, one adult male, two adult 

 females, two juvenal males, one male in first winter plumage ; Sergief 

 Island, one male in first winter plumage. The adults' are all in worn 

 breeding plumage or just beginning the annual molt. Of the young 

 birds, some are in juvenal plumage throughout, some are partly 

 through the post- juvenal molt, and two, from Great Glacier, August 

 10, and Sergief Island, August 27, respectively, are in first winter 

 plumage throughout. 



I had supposed that the form of fox sparrow that would be found 

 inhabiting the mainland coast of this part of Alaska would necessarily 

 be p. i. townsendi, which is known to occur much farther south on cer- 

 tain of the islands. Our Stikine birds, however, unquestionably are 

 not townsendi; for the present, at least, they must be considered as 

 fuliginosa. In my "Eevision of the avian genus Passerella" (1920, 

 p. 149), I have described a series of fox sparrows, winter visitants 

 taken mostly in the vicinity of Berkeley, California, that I have re- 

 ferred to fuUginosa, although they are not typical, of that form. The 

 statement there made is that these birds are too unlike summer ex- 

 amples of fuliginosa from Washington and Vancouver Island to come 

 from that region, and that tftey must be migrants from some other 

 section. It was intensely interesting to discover that the Stikine Kiver 

 summer birds exactly matched the winter birds described from Cali- 

 fornia. 



As between Alaskan examples of townsendi and the Stikine River 

 fuliginosa, we have in both series, for comparison, adults in similarly 

 worn breeding plumage ; also young in juvenal plumage, molting into 

 first winter plumage, and in first winter plumage throughout. The 

 color differences are apparent in every stage. The discovery of fuligi- 

 nosa in this part of Alaska and British Columbia discloses certain 

 departures from the distribution of that subspecies and of townsendi 

 as given by me in the "Revision" above cited (Swarth, 1920, pp. 144, 

 149; map, fig. N). Fuliginosa evidently occurs from Puget Sound 

 northward to the Stikine River, but, north of Vancouver Island, prob- 

 ably on the mainland only or perhaps on islands close to the British
