BLACKTOOTED FERRET. 
The pelage is of two kinds of hair, it is short soft and very fine, the 
outer and interspersed hairs are not so fine, but are not long and very 
coarse. The fur is finer than that of the mink or pine martin, and even 
shorter than that of the ermine. The hairs below the ears, under the 
forearms and belly are the coarsest ; the tail is cylindrical, and less 
voluminous than that of the mink, containing more coarse hair, and less 
fine fur, than in that animal. 
COLOUR. 
The long hairs on the back are at the roots whitish, with a yellowish 
tinge, broadly tipped with reddish-brown ; the soft under fur is white, 
with a yellowish tinge, giving the animal on the back a yellowish- 
brown appearance, in some parts approaching to rufous ; on the sides 
and rump the colour is a little lighter, gradually fading into yellowish- 
white. Whiskers, white and black ; nose, ears, sides of face, throat, 
under surface of neck, belly, and under surface of tail, white, a shade 
of brownish on the chest between the forelegs. There is a broad black 
patch commencing on the forehead, enclosing the eyes, and running down 
within a few lines of the point of the nose ; outer and inner surfaces of 
the legs, to near the shoulders and hips, black, with a tinge of brownish ; 
the tip of the tail is black, for two inches from the extremity.

HABITS. 
It is with great pleasure that we introduce this handsome new 
species ; it was procured by Mr. Culbertson on the lower waters of 
the Platte River, and inhabits the wooded parts of the country to the 
Rocky Mountains, and perhaps is found beyond that range, although not 
observed by any travellers, from Lewis and Clark to the present day_ 
When we consider the very rapid manner in which every expedition 
that has crossed the Rocky Mountains, has been pushed forward, we can- 
not wonder that many species have been entirely overlooked, and should 
rather be surprised at the number noticed by Lewis and Clark, and by
