Eutamias amoenus propinquus Anthony. 



Eutamias amcenus propinquus Anthony, Bull. Am. Mus. Nat. Hist., 

 XXXII, 1913, p. 6. 



Type locality. Ironside, Malheur County, Oregon. 



Genl. Char. Similar to E. amcenus, but the orange hue in the pelage 

 generally darker and richer. 



Color. Facial stripes dark orange inclining to black ; stripe behind 

 eye almost wholly black; top of head mixed buff and black; sides of 

 neck, shoulders, flanks and hips ochraceous-orange ; five black dorsal 

 stripes; inner pair of light stripes ochraceous, outer pair buffy white; 

 rump grayish; underparts and inner side of limbs buffy white; tail 

 above with two black lateral stripes, central part mixed orange and 

 black, beneath, ochraceous-orange, tip black, hairs tipped with ochra- 

 ceous-orange; hands and feet warm buff. Ex type in American 

 Museum of Natural History. 



Measurements. Total length, 207; tail, 90; hind foot, 32. Skull: 

 Occipito-nasal length, 32.4; Hensel, 25.3; zygomatic width, 18; inter- 

 temporal width, 6.9; length of nasals, 10; length of upper molar series, 

 5.4; length of mandible, 13.4; length of lower molar series, 5.8. Ex

The examples of this form were obtained in August and September, 

 mostly during the latter month, and all are in fresh pelage. Speci- 

 mens of E. amoenus in the same pelage are practically indistinguishable, 

 but as a rule the Ironside examples are darker, a deeper orange. It 

 would be interesting to know if they assume the gray pelage of amcenus 

 at any season of the year.
