identical. This is true with the breeding birds; but the two 
examples of guttata in fresh fall plumage are both distinct from 
any fall specimens I have seen of nana, in their peculiar dark 
slaty-brown tone, not the warm umber brown of the latter. It 
is probable that the thrushes of Prince William Sound are really 
intermediate between guttata (which finds its extreme of char- 
acters to the westward) and nana, I judge nearer to the former. 
My hesitancy in placing them with more certainty is due to lack 
of material from Kadiak Island, Cook Inlet, ete. 
Ixoreus naevius meruloides (Swainson). 
Northern Varied Thrush. 
Common in most of the localities visited; a forest species, 
with decided preference for the edges of the woods adjacent to 
open meadows. One was repeatedly seen at Green Island forag- 
ing amone pebbles on the beach. On Hinchinbrook Island, 
noted up to timber-line. 
The following is the list of points at which the species was 
observed: Cordova; head of Cordova Bay; Hawkins, Hinchin-. 
brook, Montague, Green, Latouche, Hoodoo, Chenega, Knight, 
Dise, Eleanor, and Naked islands; Port Nell Juan; and Valdez 
Narrows. 
The nine specimens secured (nos. 1239-1247) are all adults 
in breeding plumage. Although from such diverse localities as 
head of Cordova Bay, and Hawkins, Hinchinbrook, Montague, 
and Green islands the series is extremely uniform. The five 
females are indistineuishable from the same sex in the race of 
the Alaskan interior. They differ from females of naevius at 
hand from the Sitkan district, in the constantly ashy, less brown 
dorsum, especially the tail, and in the general paleness ventrally. 
The wing- and tail-leneth is also slightly greater. The four 
males show a rather intermediate condition in that they are 
slightly darker than northern Alaskan birds, but are not so dark 
as Sitkan examples. The series as a whole allocates itself with 
the subspecies meruloides, rather than with naevius as one would 
on climatie grounds suppose.
