44 NeEtson, Mew Birds from Mexico and Guatemala. Te 
Description of type.-— Top of head and nape, including crest, black. The 
white cheek stripe extending from below eye backward along side of gular 
black patch, and the white superciliary line, so prominent in the forms of 
D. macrourus, are very indistinct in this bird. The white borders to the 
feathers also so conspicuous on the back of the neck in that species are 
absent in D. oaxace. The feathers of neck, below the black throat patch, 
and on sides of breast are mostly dark chestnut with very narrow ashy 
borders along their sides, thus producing an almost uniformly chestnut 
area. The entire bird is darker than macrourus and is characterized by a 
suppression of the lighter markings seen in that species. 
Dendrortyx macrourus griseipectus, new subspecies. 
GRAY-BREASTED WOODGROUSE. 
Type, No. 155560, U. S. Nat. Museum, Dept. Agric. coll., f, Huitzilac, 
Morelos, Mexico, Dec. 30, 1892. Collected by E. W. Nelson (Orig. No. 
628). 
Distribution — Heavy oak forest on the Pacific slope of the Cordillera, 
in the States of Morelos and Mexico. 
Description.— Basal half or two thirds of breast feathers with narrow 
rufous shaft-streaks almost entirely concealed by broad, dingy gray borders 
of overlapping feathers; general color of breast nearly uniform dingy 
gray; back, rump, wings and flanks darker and more olive than in mac- 
rourus ; flanks with very indistinct, narrow shaft-lines of rufous; size of 
macrourus. 
The type of Dendrortyx macrourus was described and figured in 
Jardine and Selby’s ‘ Illustrated Ornithology’ (text to plates 38 and 
49) and its range given as ‘Mexico’. The description given in 
the work quoted applies most closely to birds from the mountains 
about the Valley of Mexico. 
The Zéetrao marmorata of La Llave, from the mountains about 
the same Valley, is undoubtedly a pure synonym of macrourus. 
Taking birds from these high, pine and fir clad mountains as 
typical representatives of the species, specimens from other parts 
of southern Mexico show variations worthy of recognition as 
geographical races. .
