as in the ¢; the breast is olive-gray. The changes of plumage are parallel with those of L. 
gambeli. Lower portions of California and Oregon; E. nearly to the Colorado River; abun- 
dant. A fine species, entirely distinct from the next, but habits and manners in all respects 
the same; replaces L. gambeli westward. Eggs speckled, as in the next.

cervical feathers with dark shaft lines, but few dark edgings or none, and no white speckling.

the back ; other under parts whitish, the middle of the belly with a large jet-black patch; sides 
rich purplish-chestnut, with sharp white stripes; vent, flanks and ecrissum white with dusky 
streaks. Bil black; iris brown. Besides lacking the definite head-markings, the 9 wants the 
black abdominal area, where the feathers are whitish with dark lengthwise touches; crest dark 
brown, not recurved, and fewer-feathered than that of the cock. Top of head grayish-brown, 
nearly uniform froin bill to nape; throat grayish-white with slight dark pencilling. Chicks, 
in the down: Bill above reddish, nearly white below; feet dull flesh-color. Head dingy 
yellowish, with a large brown spot on the occiput, a few black, white-streaked feathers on 
‘ erown, and the crest sprouting in a week or two. Upper parts grayish-brown mottled with 
black spots, and conspicuously striped with white lines. Outer webs of the sprouting quills 
marked with blackish and whitish. Throat white; other under parts narrowly barred with 
black and tawny-white, striped lengthwise with pure white. Sprouting tail-feathers like the

Sides under the wings slightly fulvous or rufescent, but without definite stripes. Quills plain 
dusky; tail-feathers more plumbeous, marked with blackish and whitish. A broad white 
superciliary line. With the progress of the fall moult this dress changes for one like that of

pointed at one end, very obtuse the other; color buff or rich creamy, dotted and spotted all 
over with bright brown, splashed here and there with large blotches of the same; number in

which replaced by the Massena partridge; W. to Colorado R. and slightly beyond; N. to 
Utah; S. into Mexico. The characteristic game bird of Arizona.

sharply edged with black, producing a peculiar shell-like appearance; on the breast the 
feathers also with concealed reddish shaft-lines. Long feathers of the sides like the back in 
color, with white brown-edged stripes or long-oval spots. On the flanks and crissum the 
feathers lose the scaly appearance, becoming blended rusty-brown, with linear, sagittate, or 
cordate dark spots. Inner secondaries edged with buff or whitish, affording to the folded wing 
the lengthwise stripe so characteristic of N. A. partridges. Quills plain fuscous ; tail-feathers 
plumbeous. No definite stripes about the head; crest dark brown ending in pure white.
