NEW SPECIES OF AMERICAN QUADRUPEDS. 59 
lights appearing black. The hair, when blown 
asi e > exhibits a grayish-black color from the roots 
to near the tips. The tail is slightly clothed with 
short, strong bristles. 
The specimen brought by Mr. Townsend is 
thicker, and about an inch longer. It has a white 
stripe, about two lines wide, commencing under

inch and a half of the insertion of the tail ; there is 
also a white streak commencing on the forehead, 
and extending along the snout. 
The specimen of Mr. Townsend is labelled “Banks 
of the Columbia river, May 9th, 1835.”

of the former also has thirty-six" teeth, as I have 
ascertained from an examination of many specimens, 
and in this respect their characters are correctly 
given by F. Cuvier. From a skull of the adult S. 
canadensis, Dr. Harlan evidently formed his S. 
Pennsjlvamca, which, I think, cannot be continued 
as a true species. The specimen which he de-
