A NEW BLUE GROSBEAK FROM CALIFORNIA. BY J. GRINNELL.

[Proc. Biol. Sot. Wash., vol. xxiv, June 16, 1911, p. 163.]

The California Blue Grosbeak, here named Guiraca caerulea salicarius, (type locality Colton, San Bernardino County), is separated from G. c. lazula mainly on the smaller size and different proportions of the bill. The two forms are indistinguishable in color, both differing from G. c. caerulea of the South Atlantic States in the paler blue coloration of the male bird.
