Vol. IX] TAYLOR— COOPER'S MAMMALS HI 



''T[amias] Townsendii," Cooper, Amer. Nat., 2, 1868, p 

 531 (nearly intermediate between forms found east and west 

 of Cascade Mountains). 



Specimens examined. — Two : Nos. 4754, Mus. Comp. Zool. 

 Harvard Univ.; 212/1183 U. S. Nat. Mus. No. 212/1183: 

 original label missing; specimen collected at Klickitat Pass, 

 4500 ft, Skamania County, Wash, (see Amer. Nat., 2, p. 

 531), July, 1853, by Dr. J. G. Cooper. No. 4754: original 

 label missing also; one label attached to the specimen reads 

 "N. Pacific R. R. Survey, Gov. J. J. [so] Stevens, 211 Tamias 

 cooperif [the cooperi has been crossed out and toimisendii 

 written in] W. T. Cascade Mts. Lat 46 1182 Dr. J. G. 

 Cooper." 



These specimens are cotypes of Eutamias townsendii 

 cooperi, which appears to be worthy of recognition. They 

 have been remade into modern study skins. ^® 



Specimens of Eutamias tozvnsendii from the Cascade Moun- 

 tains of Washington and Oregon are paler in comparable 

 pelage than those from Astoria, Tillamook, Aberdeen, Quini- 

 ault Lake and other localities on the coast. They appear to 

 show a mass difference in cranial characters, also, the moun- 

 tain form, E. t. cooperi, tending to have larger incisors and 

 heavier zygomata than typical tozvnsendii. 



Eutamias speciosus f rater (Allen)
