Young in juvenal plumage : — Female (No. 15,973, San José del Cabo, Octo- 
ber 31, 1887). Above, including the crown, uniform pale wood brown, the 
greater and middle wing coverts clayey buff; wings and tail light clove brown, 
the quills edged with ochraceous, the tail feathers tipped with the same, form- 
ing obscure terminal spots; middle of the breast and fore part of the abdomen 
brownish white ; sides of the breast dull olive gray ; remainder of the under 
parts rusty ochraceous, deepest on the under tail coverts, crissum, and flanks ; 
buffy of throat bordered on each side by a dusky malar stripe which, above, 
is separated from a still more obscure rictal stripe by a narrow interval of 
buffy; sides of the head uniform with the back; lores, however, distinctly 
buffy ; a few obscure, dusky spots on the breast. 
In the specimen just described the feathers of the jugulum and breast seem 
to be largely those of the first winter plumage. There are also a few feathers 
of this plumage among the interscapulars, but otherwise the bird, although 
taken so late in the season, is unmistakably in juvenal plumage. 
Another female (Triunfo, December 5, 1887), apparently a young bird in 
winter plumage, has the spots on the jugulum as well defined as in many of 
the spring specimens. The breast and a portion of the abdomen are also finely 
spotted with dark brown, a feature which I do not find in any other example 
in the entire series. This spotting is probably a characteristic of the juvenal 
plumage which, in this individual, has reappeared in the first winter plumage. 
It will be remembered in this connection that young in first plumage of the 
allied forms P. f. mesoleucus and P. fuscus are rather thickly and generally 
spotted over most of the under parts. The absence of these markings in 
No. 15,973 is dne, no doubt, as above suggested, to the fact that the feathers of 
the breast had been already changed for those of the first winter plumage. 
Most of the autumnal birds in the series before me have the greater and 
middle wing coverts tipped with ochraceous. In some of them the color of
