5- Sciurus Douglassii, Bennett. S. Townsendii, 
nob. Douglass’s Squirrel. 
This species, in the form, of its body, is not very 
unlike the Sciurus hudsonicus ; its ears and tail, 
however, are proportionably much shorter ; it is 
about a fourth larger, and, in its markings, differs

Head considerably broader than that of the Sci-

body long and slender; ears rather small, nearly 
rounded, slightly tufted posteriorly. As usual in 
this genus, the third inner toe is the longest, and 
not the second, as in the Spermophilus.

a few lighter colored hairs interspersed, giving it a 
dark brown appearance ; when closely examined, it 
has the appearance of being thickly sprinkled with 
minute points of rust color on a black ground. The 
tail, which is distichous, but not broad, is for three-

middle, the fur is plumbeous at the roots, then ir-

extremity of the tail the hairs are black from the 
roots, tipped with light brown. The inner sides of 
the extremities, and the outer surface of the feet, 
together with the throat and mouth, and a line
