1910] Grinnell_—Birds: Alaska Expedition, 1908. 417 
A careful comparison of the ten examples from Prince Wil- 
liam Sound with an adequate series of grinnelli from the Sitkan 
district, shows no discernible differences. The smallness of gen- 
eral size, and darkness of coloration are just as extreme in the 
former as in the latter. I had an a@ priori notion that the former 
would at least be intermediate towards the Regulus c. calendula 
of interior and northern Alaska, because this subspecies has been 
recorded as the breeding form of the Cook Inlet region; but I 
find no intermediate individuals. 
Hylocichla guttata guttata (Pallas). Alaska Hermit Thrush. 
Abundant in the Prince William Sound region both on the 
various islands and the mainland. At Cordova Bay Miss Alex- 
ander notes that the woods above the floor of the valley seemed 
to be deserted by all birds save the hermit thrush. At Hawkins 
Island they were seen everywhere from tide-water to timber-lne ; 
Dixon came upon one singing on the very summit of a mountain 
on that island, June 22. On Hinehinbrook Island, where the 
species was also abundant throughout the timber, Heller saw one 
far above timber-line, which refused to be frightened away from 
a small cliff where it may have had a nest. At Zaikof and Han- 
ning bays, Montague Island, and at Green Island, hermit thrushes 
were common; several were noted along the beaches at low tide 
hunting for food among the rocks. Additional record stations 
were: Head and mouth of Port Nell Juan; Latouche, Elrington, 
Hoodoo, Chenega, Knight, Dise, Eleanor, and Naked islands; 
and Valdez Narrows. Heller noted a few at the latter point 
between September 12 and 21. 
A series of twenty-four specimens was obtained (nos. 1448- 
1471). Three of these are juvenals (August 4, 14, and 15). 
Two are birds-of-the-year in newly acquired first winter plu- 
mage (August 14 and 26). The remainder of the series consists 
of breeding birds in more or less worn summer plumage. As 
compared with H. g. nana (as represented by a large series from 
the Sitkan district of southeastern Alaska), the thrushes of 
Prince William Sound are slightly larger and ashier, less of a 
bright brown. But this is only an average difference, for I can 
easily select individuals from the two series which are absolutely
