Seiurus noveboracensis notabilis Ridgway. Grinnell Water-Thrush 

 At Glenora, July 7, an adult male was obtained that was un- 

 doubtedly nesting near-by. At Doch-da-on Creek, July 21, another 

 adult male was taken. 



Of these two birds, the Glenora specimen (no. 40197), as com- 

 pared with the one from Doeh-da-on Creek (no. 40198), is appreciably 

 smaller, with smaller bill, is darker colored throughout, and is 

 noticeably more yellowish below. This may represent individual varia- 

 tion toward the eastern subspecies, Seiurus n. noveboracensis. The 

 two Stikine specimens, however, resemble each other more nearly than 

 either one resembles any eastern example at hand. 



Oporornis tolmiei (J. K. Townsend). MacGillivray Warbler 

 Abundant throughout the whole of the region we explored. First 

 noted at the Junction, June 1, one bird seen and another heard 

 singing. During the next few days they were evidently arriving in 

 abundance, and thereafter the song was heard nearly everywhere we 

 went. The first young out of the nest was seen July 13, at Doch- 

 da-on Creek.- A day or two later they were emerging in numbers, 

 and as we went through the woods fussy parents in attendance 

 followed us about. The species was noted in moderate abundance 

 at each of our subsequent stations — Flood Glacier, Great Glacier, 

 and Sergief Island. Last noted, a single bird on Sergief Island, 

 September 3. 



Nine specimens were collaeted (nos. 40199-40207). An adult male 

 taken at Flood Glacier, August 4, is finishing the annual molt; the 

 body plumage is practically renewed, but wing and tail feathers are 

 but half -grown. Two young birds taken August 4 and 12, respectively, 

 are in first winter plumage throughout. 



Although the MacGillivray warbler is so abundant in the upper 

 Stikine Valley, that region must be nearly the northern extreme 

 reached by the species. It is not included in E. M. Anderson's (1915a) 

 list of birds of the Atlin District, less than two hundred miles to the 

 northward. I do not know whether this warbler should be considered 

 primarily as a species of the interior or of the coast, or whether it is 

 one of the few birds that occurs in equal abundance in both regions. 

 It has been found in summer at various points on the Alaskan coast 

 (Swarth, 1911, p. 101).
