NORTH AMERICAN FAUN..
is a small spot of ochraceous-buff and a faint wash of the same color
on the throat. Similar chromatic abnormalities crop out in several
specimens from the type locality, and one specimen (No. 204998,
U. S. Nat. Mus.) has as a dental abnormality a supernumerary left
upper premolar.
Intergradation of this form with oradrius is clearly indicated in
specimens from the west slope of the Cascade Mountains in Oregon
and Washington. Specimens from Vida, McKenzie Bridge, and
Three Sisters, in Oregon, approach orariws in color and in cranial
characters, though distinctly referable to scheffem. Specimens from
Mount Vernon, Wash., are slightly darker in color than specimens
from Walla Walla, but the skulls are almost identical in essential
characters with the type series. Specimens from Skykomish, Wash.,
are nearly as dark as typical orarius, but are referred to schefferi
because of cranial characters which, although approaching orarius,
are much nearer schefem.
Specimens examined.-Total number, 59, as follows:
British Columbia: Chilliwack Valley, 2; Chiloweyuck Depot, 2; Fraser River
(near New Westminster), 1;1 Sumac, 6.
