HABITS. 
This animal was first noticed, by Lewis and Clark, as the large Red 
Fox of the plains, (vol. 2, p. 168,) and was referred to by us in the firs) 
volume of the Quadrupeds of North America, p. 54, where we described it 
from a hunter’s skin. 
Having obtained a beautiful specimen from Captain Rhett, of the 
United States Army, we gave it the name of Vulpes Utah , as it is, so far as 
our information extends, chiefly found in the Utah territory, although it 
probably ranges considerably north of the Great Salt Lake. 
The habits of this beautiful Fox are similar to those of the Red Fox, and 
it runs into many varieties of color. 
Captain Rhett informed us that he killed the specimen, kindly presented 
to us by him, near Fort Laramie. 
Several specimens of Vulpes Utah have been received at the Smithsonian 
Institution, and it will probably soon be well known.
