(3) BOREAL CASCADE SPECIES NOT KNOWN FROM SHASTA OR THE 
SIERRA. 
Eleven mammals, 2 birds, 3 fir trees, and a number of shrubs and 
other plants which inhabit the Cascade Range in Oregon are not known 
to occur on Shasta or in the Sierra Nevada. One of the mammals 
(Eutamias townsendi) does not reach as far south as the southern end 
of the Cascades, and two others (Aplodontia major rainiert and Sciurus 
cascadensis) are only subspecifically separable from corresponding forms 
in the Sierra. The remaining eight are independent specific types not 
represented on Shasta or in the Sierra, and all of them push south to 
the extreme southern end of the Cascades immediately across Klamath 
Gap from Shasta.

(6) BIRDs. 
Hylocichla ustulata. Leucosticte tephrocotis littoralis.? 
These mammals are restricted to the soutbern part of the Sierra and none of them 
come as far north as the mountains about Lake Tahoe. 
2 Leucosticte tephrocotis littoralis brecds in the Cascades of Washington but is not 
actually known from the Cascades of Oregon. It is likely to be found among the 
glaciers of Mount Hood and The Sisters when the birds of these mountains are 
studied.
