LOPHORTYX GAMBELII, Nuttall. 
Gambel’s Partridge. 
Lophortyx gambelii, “Nurraut,” Gamber, Pr. A. N. Sc. Phil. I, 1843, 260.—McCatt, Pr. A. N. Sc. V, June, 
1851, 221. 
Callipepla gambelii, Goutv, Mon. Odont. pl. xvii.—Cassry, Illust. I, 1, 1853, 45; pl. ix. 
Callipepla venusta, Gouin, Pr. Zool. Soc. XIV, 1846, 70. 
Sp. Cu.—Head with a crest of five or six purplish black feathers, about as long as the bill and head together, or a little longer. 
Upper parts, with the neck all round, and the breast, plumbeous gray ; the shafts of the feathers brown ; those on the neck 
above and on the sides edged with same. Anterior half of head all round, with the chin and upper part of throat, and a large 
spot on the belly, black ; the forehead streaked with hoary gray. Top of the head chestnut, bordered anteriorly and laterally 
by black, immediately succeeded by an abruptly defined white stripe. A second s-ripe starts from the posterior corner of the 
eye and borders the black on the side of head and on the throat all round. Belly pale brownish yellow ; the sides of the body 
dark orange brown, broadly streaked centrally with white. Inner edges of tertials light brownish yellow. Tail light plumbeous. 
Female without the black and white of the head and the black of the belly, and only aslight trace of the chestnut crown ; the 
erest shorter and of fewer feathers. . 
Length, 9.50 inches ; wing, 4.50; tail, 4.25. 
Hab.—Upper Rio Grande and Gila to the Colorado of California. 
In many specimens there is a fine mottling on the outer surface of the wings, and an appear- 
g gs, PI 
ance of the same on the gray of the breast and back, but this latter is merely an optical illusion. 
The feathers on the forehead are stiff and bristly, their central portions or shafts are black ; 
the lateral filaments hoary gray, although the general effect is nearly black. 
This fine species belongs chiefly to the Rocky mountain region, from the Upper Rio Grande 
to the Colorado river. It is found as far north on this river as the parallel of 36°, and is very 
abundant in Sonora. In the limits assigned it appears to replace the L. californicus, which is 
peculiar to the western slope.
