the West Humboldt ilouiitaiiis, Avliere it was not uncommon in Septembor. 

 Those found had probably migrated from the region to the northwestward, 

 or from the Cascade ^Mountains or the country adjacent, since examples of 

 Zonotrkhia coronata, Pipilo orcgonus, and Melosplza guttata were obtained at 

 the same place.

This species was met with only during its autumnal migi-ations, when it 

 seemed to be not uncommon in the month of September among the canon 

 thickets of the western slope of the Clover Mountains. A single specimen 

 was also shot in a bufliilo-berry thicket in ISuenu Vista Cailon, on the east- 

 ern slope of the West Humboldt Mountains, in September of the preceding 

 yeai'. It is still a question whether sucli individuals of this species were 

 migrants from the higher portions of the mountains or from a more northern 

 region; but that their migration was not vertical is most pix»bable.
