 MAR., I902. [ THE CONDOR 43 talis. In the more arid Lassen Co. it ig probable that typical frontalis pushes farthest north, perhaps even entering Modoc Co. I have not seen birds from the Siskiyou Mts. proper, but they are almost certainly carbonacea, which with equal certainty can be said of the form inhabiting the western slope of the Cas- cades of Oregon. Ranging down the east slope this form intergrades through the Maury and Blue Mountain region with annectens. Tho the Fort Klamath bird shows some tendencies in the direc- tion of annectens, I do not believe the form is the result of the intergradation of /rontalis and annectens as has been sug- gested to me. The position of the Fort would indicate stock from the Cascade Range which adjoins the Willamette Valley Any annectens blood is likely to be simply an infusion from the Blue Mts. via the east slope of the Cascades, frontalis being altogether out of the proposition. With these limitations the map represents in a general way our present knowledge of the distribution of(he four essentially coast races.
