Sp. Cu.—Body seven to eight inches long—longer than the tail. Ears moderate, broad, coated with long hairs springing 
from the back and projecting beyond in a tuft. Tail narrow, flat. Hind feet densely hairy to the tubercles at the base of 
the toes, the under surfaces of which are themselves somewhat coated ; in summer somewhat naked. Above and on the 
sides mixed black and grayish rusty. A broad wash of bright ferruginous down the back and upper surface of the tail. 
Lower surface of the body dull white ; hairs not annulated, except in very northern specimens. ‘Tail rusty on the margin, 
within which is a narrow band of black, both colors greater in extent at its end. Hairs above uniform ferruginous, not 
annulated ; beneath annulated like the sides. 
Although not collected by any of the expeditions, I have thought proper to give a description 
of this species, to serve as a standard of comparison with several others closely allied to it in sub- 
generic as well as specific characters. How far west its range extends cannot at present be 
determined, none having as yetebeen received by the Smithsonian Institution beyond Wisconsin. 
It is found throughout the Atlantic States, as far north at least as Labrador, and to the Missis- 
sippi river. As expressing probably the average of the species, I have selected for description 
a specimen from Cleveland, Ohio, presented by Prof. J. P. Kirtland. 
Body about eight inches in length, stout. Head rather short and broad. Whiskers black, 
much longer than the head, extending back to the axille. Numerous long whisker-like hairs 
projecting beyond the shorter fur on the fore limbs. Extreme end of nose hairy, the septum 
only being naked. Ears broad, rounded ; their convexity quite thickly coated with long hairs, 
completely concealing it from view on that side. Some of these hairs project beyond the margin 
more than half an inch, the longest being towards the tip. The concavity of the ear is coated 
with short hairs. The two middle fingers are equal in length. The inner or second reaches 
to the base of the claw of the one next to it, and is a little longer than the outer. The palms 
are naked. On the hind foot, the third and fourth toes are equal ; the second a little shorter ; 
the first or inner shorter than the fifth or exterior, which scarcely reaches to the base of the
