Distribution.— The mixed forest of oaks, pines and firs on the high 
Cordillera of Guerrero above 8000 feet. j 
Description.— Rather smaller than the other forms, with a longer, 
slenderer beak. The most conspicuous character is the heavy rufous shaft- 
lines of the feathers along the entire flanks, which do not become obsolete 
posteriorly as in the others. The back is very dark and the rump and 
upper tail-coverts lack the mottling of whitish conspicuous in the others. 
The tail also is darker.

bordered with dull, dark gray; middle of back, rump and upper tail-coverts

to main color; lower tail-coverts mottled, or coarsely variegated with 
rufous, blackish and white. 
Dimensitons.— Wing 100, tail 54, culmen 15, tarsus 29. 
Colinus coyolcos is the nearest relative of this bird, but in com- 
paring eleven specimens of each species, including both sexes, 
it appears to be perfectly distinct. 
It is named in honor of Mr. Osbert Salvin, one of the authors 
of the ‘ Biologia Centrali-Americana,’ which has added so much 
to our knowledge of Mexican and Central American bird life.
