Bangs A New Race of Pine Squirrel 



ing from pale ochraceous-buff to (in a few specimens) ochraceous ; a broad 

 black band separating colors of upper and under parts, usually present 

 (in one or two specimens nearly obsolete) ; orbital ring pale ochraceous- 

 buff; tail: hairs of upper surface tawny at base, then black and white 

 tipped ; of lower surface dull tawny olive at base, then black and white 

 tipped ; whiskers, black.

Remarks. Compared with S. h. douglasi, S. h. orarius has the same 

 small ear, but differs very much in color, the dark olive shades of the 

 upper parts of orarius, with but little rusty anywhere, being in marked 

 contrast to the ferruginous dorsal region of douglasi. The white fringed 

 tail of orarius, with a broad black subapical band, can always be told 

 from the rusty yellow fringed tail of douglasi. The under parts are, as a 

 rule, much paler, more ochraceous-buff, less ochraceous- rufous than in 

 douglasi. 



With S. hudsonicus calif ornicus, S. Jiudsonicus orarius scarcely needs com 

 parison, the large ear, white or creamy white under parts, and bright 

 ochraceous-rufous dorsal stripe of cali/ornicus at once distinguishing it. 



Most of my specimens were taken on December 9, one only being taken 

 in midsummer. The specimens taken December 9 show all the stages 

 from probably the summer to full winter coat, it appearing to be the time 

 at which that change takes place. There seems to be but a slight differ 

 ence in color between the winter and summer pelages, though the black 

 side stripes probably nearly disappear when the full winter coat has been 

 acquired, and the ears are more tufted and the under parts more vermic- 

 ulated with blackish.
