the bill as well as in the length of the wings and tail, but the latter is nearly 
always shorter than in Arizona specimens of superbus. Many of my Sonora 
representatives of the latter are, however, positively indistinguishable from the 
larger examples of zgneus. 
Females. Several of my specimens have the entire top of the head as well 
as the cheeks, throat, and breast, strongly tinged with red ; in others, these parts 
are perfectly plain, while the two styles are connected by a chain of variously 
intermediate birds. There is also much variation in respect to the amount of 
blackish on the chin, lores, ete. In afew examples this blackish is almost 
wholly wanting. 
Winter plumage : — Adult males in autumn and. early winter differ from 
spring males only in having the feathers of the back more broadly tipped with 
purer ashy ; those of the crown with dull olive; those of the under parts with 
grayish white. 
Young males in their first winter plumage have the back, nape, and sides of 
the neck uniform ashy, or brownish ashy, with, however, much concealed red- 
dish; the top of the head and crest strongly washed with olivaceous; the 
under parts, except the throat and under tail coverts, much variegated with 
dull yellowish olive; the bill mottled with large patches of blackish. The 
tint of the red of the head and under parts varies quite as much in these young 
males as with spring adults, showing that it has no connection with age or 
season. 
Young females in first winter plumage have the back, wing coverts, inner 
secondaries, and exposed outer surfaces of most of the remaining wing quills, as 
well as all the tail feathers, much ashier than in breeding birds; the top and 
sides of the head strongly ochraceous ; the throat, lores, etc., darker grayish ; 
the rest of the under parts deep brownish ochraceous; the bill with the base 
and tip of the maxilla brownish, but with no pronounced blackish as in the 
young male. The color of the under parts fades very gradually as the sea- 
son advances, some of my February specimens being only slightly paler than 
the October and November ones. 
The St. Lucas Cardinal is quite as abundant and almost as widely dispersed, 
near the southern extremity of Lower California, as the preceding species, but 
being of more sedentary disposition its numbers in any given locality vary only 
slightly, if at all, with the different seasons. It occurs practically everywhere 
from the shores of the Gulf to among the foot-hills of the mountains, but ap- 
parently not on the summits or upper slopes of the latter. Mr. Frazar found 
it most numerously at La Paz and Triunfo, least so at San José del Cabo, while 
he did not meet with a single specimen on the Sierra dela Laguna. Mr. Bryant 
saw the bird occasionally “among thick high shrubs and trees,” on Santa 
Margarita Island, and it was common at Comondu, while further northward he 
traced it nearly to latitude 29°. Like the St. Lucas Towhee it is probably 
confined to the Peninsula. It is represented in southern Arizona and northern ~ 
Sonora respectively by the closely allied C. c. swperbus, and in southern Sonora 
and Sinaloa by C. c. affinis and C. c. sinaloensis. No form of this genus is in-
