males (Nos. 321-323) June 29 and July 1; Stephens and Dixon 
secured a male and a female, respectively, July 8 and 14 (Nos. 
324, 325). 
The five specimens from Glacier Bay are fully as typical of 
the race as the two from Admiralty Island. I have compared 
the series with my two co-types from Sitka, and find them iden- 
tical in every respect. 
Hylocichla ustulata ustulata (Nuttall). 
Russet-backed Thrush. 
Stephens and Littlejohn secured four adult specimens of this 
thrush at Red Bluff Bay, Baranof Island, June 13 to 19 (Nos. 
387-390), and at Coppermine Cove, Glacier Bay, Dixon took one 
adult July 17 (No. 279), remarking in his notes that the “‘species 
was fairly common, but unlike the hermit thrushes, the russet- 
backs get up in the tree tops to sing.”’ 
The five skins show no peculiarities when compared with a 
series of ustulata from farther south along the Pacific Coast.

They approach not at all the race ‘‘almae’’ (= swainsonii). 
Hylocichla guttata nana (Audubon). Dwarf Hermit Thrush. 
At Windfall Harbor, Admiralty Island, Stephens and Dixon 
record that several hermit thrushes were caught in mouse-traps 
set for shrews. Both there and at Mole Harbor this bird could 
not, however, be considered common. Seven specimens were 
secured April 25 to June 1 (Nos. 417-423). At Hawk Inlet the 
species was noted, August 1 to 9. On Baranof Island, at Red 
Bluff Bay, two were taken June 17 and 18 (Nos. 431, 482) ; and 
at Bear Bay a juvenal was secured August 23 (No. 433). Sevy- 
eral were seen at Hooniah, Chichagof Island, June 21 to 27. 
And at Idaho Inlet, according to Stephens, ‘ 
near camp that contained four young ready to fly, July 22. The 
‘a pair had a nest 
nest was built in a niche in a perpendicular moss-grown bank 
about four feet above the bottom.’’ Five skins were obtained on 
Chichagof (Nos. 395-399). 
On both shores of Glacier Bay, June 27 to July 20, the species 
was rather common, and several young birds were trapped. Eight
