158 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
Individual variations: — Spring males. Red of the crest sometimes pure 
dark wine color, sometimes strongly tinged with blackish. Red of the under 
parts sometimes pure and continuous from the chin to the crissum, sometimes 
interrupted by ashy on the breast and lower abdomen. Red of the capistrum 
usually pure, but occasionally tinged very slightly with blackish. 
Spring females. Capistrum, throat, breast, abdomen, crissum, and under 
tail coverts sometimes plain, sometimes tinged with red. 
Winter plumage :— Adult males. Crown, back, sides of neck, and entire 
under parts, except the throat, strongly tinged with yellowish brown or brown- 
ish olive, which, over the red of the median lower parts, forms merely a nar- 
row tipping at the ends of the feathers. 
Young males, Differing from adults in autumn only in having the red 
more restricted and often almost wholly concealed, on the forehead, as well as 
over most of the breast and lower abdomen, by the brownish tipping above 
mentioned. 
Females. Wings and tail grayer than in spring birds, the general coloring 
clearer and richer, the upper parts brownish ashy, the lower parts rich buff 
tinged with brownish ashy on the breast and sides of neck and body ; the 
upper tail coverts, inner secondaries, and greater and middle wing coverts, 
tipped with light brownish of the same shade as the back, this brownish, on 
the wing coverts, forming two ill-defined bands. If my series of autumnal 
females contains both young and adults I am unable to distinguish them. 
This bird appears to be strictly confined to the Cape Region, where it is 
nowhere very common. Mr. Belding considered it more numerous in the 
interior than near the coast, but Mr. Frazar found it in the greatest numbers 
at Triunfo and San José del Cabo, the latter place being, of course, directly on 
the coast. About La Paz, however, only a single specimen was seen, and but 
one was obtained on the Sierra de la Laguna. At Santiago four were taken, 
and there is a skin in the collection from San José del Rancho. The bird is 
doubtless resident wherever found. 
No representative of this genus is known to inhabit any part of California, 
but the closely related P. sinwata occurs in southern Arizona and western 
Mexico.
