Hasirat. — Alaska et Columbia Britannica. 
DerscriPTion. — Male, adult, No. 131807 U.S. Nat. Mus.; Kadiak Island, 
Alaska, June 7, 1893; C. H. Townsend. Above olive green, somewhat more 
yellowish on crown, auriculars, rump and sides of neck, but with no well- 
defined yellow crown-patch. Longest feathers of the superior tail-coverts 
with central portions olive brown. Lores, orbital ring, conspicuous 
superciliary stripe and lower parts, pure gamboge yellow, slightly shaded 
with olive green on sides, which, together with jugulum and breast, are 
streaked with brick red as in morcomz. Wings dark olive brown, the lesser 
coverts like the back, the median, greater and primary coverts, with outer 
margins of remiges, edged with yellowish olive green; the inner margins 
of the last broadly canary yellow at base, this color decreasing in amount 
toward the ends of the feathers. Axillars and under wing-coverts lemon 
yellow. Tail-feathers dark olive brown, the inner webs broadly lemon 
yellow, this color on the outer pair occupying all but aterminal guttate 
spot,and diminishing in extent on each succeeding pair, until it disappears 
entirely from the two middle rectrices; basal two-thirds of external web of 
outermost pair also lemon yellow. Outer edges of all the rest, including 
both margins of two middle feathers, narrowly olive green. 
Typical Dendroica estiva rubiginosa differs from D. @. morcomi 
most noticeably in its darker, less yellowish and almost uniform 
upper parts, the crown and rump being not in appreciable contrast 
to the olive green of the back. In consequence of the olivaceous 
color of the whole pileum, both the yellow eye-ring and super- 
ciliary stripe are much more clearly indicated. Minor characters 
exist in the more olivaceous tint of the auriculars and sides of the 
neck and head; also in the duller, sometimes scarcely yellowish 
external edging to wing-quills and their coverts. The color below 
averages slightly paler, especially on the throat and the lower 
tail-coverts, though upon examination of a larger series this may 
prove merely an individual variation. There seems to be no 
material difference in size. From Dendroica estiva the present 
form is further separable by the narrower streaking of the breast. 
The characters here ascribed to rwdiginosa are remarkably con- 
stant in all of the six adult males from Alaska, though a specimen
