uniform, owing to the 1)lencliMg' effect of light edgings of the feathers; 
cervix, l)end of wing and upper tail-coverts paler and more pinkish; 
black areas obscured; yellow of head and throat deeper; breast heavil}^ 
streaked with dusky and cinnamomeous. 
AduH feii/ale in winter plumage. — No. 134813, U.S.N. M.; San 
Clemente Island, California, August 28, 1894; Dr. Edgar A. Mearns.— 
Similar to the breeding dress, but upper parts paler and more uniform; 
the yellow of head and throat deeper; the black areas obscured by 
lighter; the })reast tinged with cinnamon and heavily streaked with 
duskj% 
Young in first pJu mage. — Male, No. 47, collection of F. S. Daggett; 
Santa Barbara Island, California, May 14, 1897. — Upper parts warm 
bistre, paler on the head, where spotted with darker brown and with 
butty; hind neck nuich mixed with l)utty; back and scapulars spotted 
terminally with buft'y white; rump deep ochraceous, somewhat mixed 
with dark brown; tail clove brown, excepting the two central feathers, 
which are lighter and rufescent. Wings Ijroadly edged externally 
with ochraceous, most of the coverts tipped with whitish. Superciliary 
stripe and ocular region dull 3'ellowish white; cheeks light grayish 
brown; jugulum and upper breast dpll ochraceous, with spots of 
dusky; remainder of lower surface dull white with a decided wash of 
yellowish. 
Notwithstanding Dr. Dwight's statement^ that he could not distin- 
guish the Santa Barbara Islands birds from xtrigata.^ they constitute an 
easily recognizable race which, though curiously enough most closely 
allied to strigata^ yet differs in the darker color above, particularl}^ on 
cervix and bend of the wing; in the more gra3"ish tone of the back and 
scapulars; the alisence of j^ellow on the l)reast; and the nnich more 
conspicuous streaking on this part. All these characters, with the 
exception of the color of the cervix and liend of wing, are much 
more striking in autumn and winter than in summer. At the 
former seasons the yellow suffusion on the occiput and cervix of strigata 
is quite marked, this being an additional point of difference between 
the two races. From merrilli the island ])ird differs in smaller size 
and much more reddish coloration; while i\o\\\ actia of the adjacent 
mainland it ma}^ lie separated by its conspicuously darker coloration 
throughout. 
The young of im^xdaris^ which appear here to be described for the 
first time, are, Avhen due allowance has been made for the very con- 
siderable range of individual difference, much darker, and, particularly 
on the wings, somewhat less ochraceous alcove than the young of aetia; 
the breast is usually more dingy, and the remainder of the lower sur- 
face is washed with dull yellowish instead of being nearly pure white. 
Compared Avith a limited series of the 3^oung of merrilli., they are
