Distribution.— ^\\^ mixed forest of oaks, pines <Tnd firs on the high 

 Cordillera of Guerrero above 8000 feet. 



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.

Colinus coyokos 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 Ceiitrali-Americana,' which has added so much 

 to our knowledge of Mexican and Central American bird life.
