 sides of head and neck and lateral under parts sepia or sooty brown, the 

 upper tail-coverts and tail slightly more castaneous; spots on under

Type, No. 157611, U. S. Nat. Mus. (Biol. Surv. Coll.), $ ad., Neah Bay, 

 Washington, June 10, 1S97; E. A. Preble. 



Range. —Breeding in coast district of southwestern British Columbia, 

 including Vancouver Island, and northwestern Washington; south in 

 ■winter to coast of northern California (to San Francisco, etc.). {P. i. 

 toivnsendi breeds in the Sitka district ; P. i. unalaschcnsis breeds on 

 Kadiak Island and adjacent mainland of Alaska, but migrates much 

 farther south than the other two forms, being the only one occurring 

 commonly over the greater part of California.) 



Zonotrichia leucophrys nuttalli. Nuttall's Sparrow. 



Zonotrichia gambeli and Z. leucophrys gambeli, Auct. nee Fringilla 

 gambelii Nuttall. 



When, in 1873, I separated the lighter colored form of this 

 species of the more northern and interior districts from the darker 

 coast form, under the name of Zonotrichia leucophrys var. inter- 

 media, I erred in restricting the name gambelii to the coast form.
