talis. In the more arid Lassen Co. it is 
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 certainl}' 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 
frontalis and an?iectens 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 Ca.scades, 
frontalis being altogether out of the 
proposition. With these limitations the 
map represents in a general way our 
present knowledge of the distribution 
of the four essentially coast races.
