 from the Atlantic to the Pacific. 



But one specimen of this species was observed on our route. 



Ficoides dorsalis, Baird, (striped three-toed woodpecker :) 



ITah. — Eocky Mountain region. 



One morning, while at breakfast, in the Lower Geyser Basin, I saw 

 this and the preceding species busily engaged searching for grubs in a

 birds. This also is the only specimen of its species seen during the 

 summer.

Hah. — Rockj' Mountains to the Cascade Mountains. 



As we were crossing the main divide of the Eockj^ Mountains, on the

 in shooting the only specimen seeu of this rare and betxutiful wood- 

 pecker. 



iSphjrojnciis tJiyroideiis, Baird, (brown-headed woodpecker :)
