and whole dorsal region strongly suffused with raw sienna; the 
broad edgings of scapulars, wings and tail strongly hazel; there 
is no pure white anywhere. 
Pirst winter plumage (based on male; no. 10453, Univ. Calif.

fornia, near Nevada line; August 15, 1909; Louise Kellogg 
lower surface clear white, except for faint tinge of cream-buff 
on flanks and pectoral region, these being in addition sharply 
streaked with blackish; general effect of dorsal surface ineluding 
wings and tail black-streaked, with edgings of clay color and 
whitish; superciliary and malar stripes pale clay color; outer 
web of outermost rectrix chiefly white, and its tip and imner 
margin the same. Wing, 65.3 mm.; tail, 49.5; tarsus, 20.7; hind 
toe with claw, 15.0; culmen, 10.4; gonys, 6.7; depth of bill at 
base, 5.6. 
A selected specimen of P. s. alaudinus (male no. 1504, Univ. 
Calif. Mus. Vert. Zool.; head of Port Nell Juan, Prince William 
Sound region, Alaska; Atigust 19, 1908; Annie M. Alexander) 
in parallel plumage is decidedly brown-and-black in its general 
tone as compared with the white-and-black of nevadensis. This 
is due to the buffy suffusion of the ground color everywhere 
beneath except on the belly, to the absence of whitish markings 
above, these being replaced by clay color, and to the relatively 
great amount of deep hazel. The latter color is disposed on 
each feather (in the dorsum, lateral crown stripes, upper tail 
coverts, wing coverts and inner wing quills) as lengthwise bands 
alone each side of the black shaft area, separating the latter 
from the outermost edgings of clay color. This hazel also char- 
acterizes the streakings beneath, so that the amount of actual 
black is much reduced, or to express it in another way, replaced 
by hazel. The contrast and sharp definition to the markings 
found in nevadensis are thus lacking in alaudinus. Wing, 72.5; 
tail, 50.9; tarsus, 21.0; culmen, 9.9; gonys, 6.9; depth of bill 
at base, 5.1.
