(original description.) 
Sr. Cu.—Resembling C. virginianus in horns and general characters, but smaller. Color varying but little with season ; ashy 
or grayish brown, pointed with light gray annulation to the hairs. Tail but little longer than the ears, white beneath and on 
the sides ; whitish with yellowish rufous tinge above, except near base, where it is like the back. Gland on hind leg as long a 
the bone is thick. 
The single specimen collected of this deer is of very small size, though fully adult, as shown 
by its suckling a fawn when killed. No experiment was made as to its weight, but this could 
not have exceeded 70 pounds, as Dr, Kennerly, after killing it, threw it across a mule with perfect 
ease. 
The general impression conveyed of this deer is that of Cervus virginianus in winter dress, 
though the specimen was killed in May, and in summer fur. The head is slender and delicate. 
The ears are moderately long and rather unusually broad ; they measure 54 inches above the 
notch and 44 in width. They are rather thinly coated with hairs on both sides, though the hairs 
are much longest on their concavity or interior. 
The larmiers are not very large, and the space between them and the eye is covered with short 
velvety hairs. There are no appreciable peculiarities in the form of the muzzle. 
The tail is short, but little longer than the ears ; it measures only about 7 inches to the tips 
of the hairs, and about four to five to the end of the bone. It is depressed and hairy beneath. 
The hoofs are rather short and broad. In the hind foot the width of the side, measured along
