Creek, at the end of the nesting season, small flotks of P- gmnbeli 

 ahbrevmtus were seen on several occasions ; it was observed nowhere 

 else. Five specimens were collected (nos. 40265-40269), four on 

 July 14 in woods at the river's edge, and one on July 23, on a moun- 

 tain slope at about 3000 feet elevation, close to timber line. The 

 series consists of two adults in extremely worn plumage, and three 

 in Juvenal plumage. Oberholser (19196, p. 424) has reported the 

 occurrence of this subspecies at Thudade Lake, British Columbia. 

 The present point of record is about two hundred miles northwest of 

 Thudade Lake, and, ip a direct line, about sixty miles from the coast. 

 It must indicate about the extreme northwestern limit reached by this 

 bird. For the use of the name Penthestes gambeli abhreviatus see 

 Grinnell, 1918, p. 510.

A number of small flocks seen in the dense spruce woods at Flood 

 Glacier. The occurrence of this common coastal species at that point 

 implies its continuous distribution along the river below that station. 

 That we did not meet with it at Great Glacier and Sergief Island was 

 probably fortuitous. Nine specimens were collected at Flood Glacier 

 on dates ranging from July 31 to August 7, all young birds in juvenal 

 plumage (nos. 40270-40278). 



Regulus satrapa olivaceus Baird. Western Golden-crowned Kinglet 

 Very few kinglets were seen anywhere. From May 27 to June 4 

 several of the present species, apparently migrants, were observed at 

 different times along the trail from Telegraph Creek to the Summit. 

 Our failure to find the species subsequently may, perhaps, have been 

 because the birds were breeding in the spruce timber of the higher 

 mountain slopes, to which we made but few visits. Several times I 

 thought I heard the sibilant call note of the golden-crowned kinglet in 

 some dense timber above Doch-da-on Creek (at about 3000 feet alti- 

 tude), in July, but I was unable to see the birds. At Flood Glacier, 

 August 7, one was seen in a mixed flock of migrating small birds, and 

 there may have been others passing through at the time. Two speci- 

 mens were collected during the summer, an adult male at the Junction, 

 May 27 (no. 40279), and an adult female at Flood Glacier (no. 40280).
