DESCRIPTION. 
In size and form this species bears a considerable resemblance to the 
Cat-Squirrel (S. cinereus). It is a little longer in body, not quite as stout, and 
has shorter ears. In length and breadth of tail, they are about equal. 
The first molar tooth in the upper jaw, which in some of the species is de- 
ciduous and in others permanent, was wanting in the six specimens we ex- 
amined ; we presume, however, it exists in very young animals ; mammae, 
8, placed equi-distant on the sides of the belly ; palms, as is usual in this 
genus, naked, the rudimental thumb protected by a short blunt nail ; 
the feet are covered with hair, which extends between the toes, half con- 
cealing the nails; hair on the body, of moderate length, not as coarse as that 
of the Fox-Squirrel, (N. capistratus), but neither as fine or woolly as that of 
<Sf. cinereus. Our specimens were obtained in summer. — S ay has remarked : 
“ The fur of the back in the summer dress, is from three-fifths to seven- 
tenths of an inch long ; but in the winter dress, the longest hairs of the 
middle of the back are from one inch to one and three-fourths in length.
