_Measurements._--Five females from northeastern Washington average: total length 346; length of tail 77; hind foot 48.6; ear 20. _Distribution._--Northeastern Washington, from 15 mi. E. Tonasket (W. W. D.) east to Pass Creek Pass (U. S. N. M.) and south to Pullman (W. S. C.) along the eastern edge of the state. =Citellus columbianus ruficaudus= Howell _Citellus columbianus ruficaudus_ Howell, Proc. Biol. Soc. Washington, 41:212, December 18, 1928. _Type._--Obtained at Wallowa Lake, Wallowa County, Oregon, by G. G. Cantwell on April 13, 1919; type in United States National Museum. _Racial characters._--Similar to _Citellus columbianus columbianus_ but tail redder, especially above, and red color everywhere deeper. _Distribution._--Restricted to the Blue Mountains of extreme southeastern Washington. _Remarks._--This is at best a slightly differentiated race and upon further study, animals assigned to it may prove unworthy of recognition as a distinct subspecies. =Citellus beecheyi douglasii= (Richardson) Beechey ground squirrel _Arctomys?

Fauna, 56:150, May 18, 1938. _Type._--None. Description based on a hunter's skin from "Banks of the Columbia," probably near The Dalles, Wasco County, Oregon. _Measurements._--A male and 6 females from Klickitat County, average, respectively: total length 469, 480; length of tail 181, 198; hind foot 58, 62; ear 26, 26. _Distribution._--The Columbia River Valley from Goldendale (W. W. D.) west to the White Salmon River (W. W. D.). _Remarks._--Ground squirrels have been common on the Oregon side of the Columbia River for a long time. The specimen upon which the description was based was presumably obtained there in the early 1800's. Yet the species did not become established in Washington until 100 years later, in about 1915.
