SYNONYME. 
Geomys IIispidum. — Dr. Le Conte, Proo. Acad. Nat. Sci., Phila., 1852, p. 158. 
DESCRIPTION. 
One specimen, Mexico, Mr. Pease’s collection. This species differs 
from all the others in having the fur very coarse and harsh, and entirely 
of a reddish brown colour. Beneath it is slightly greyish, but the differ- 
ence in colour is by no means obvious. The ears are not at all prominent, 
being merely openings in the skin. The whiskers are as long as the head. 
The upper incisors are broken off, but enough remains to show that they 
were deeply grooved near the middle of the anterior surface ; it is impos- 
sible to determine if there is a second submarginal groove. The tail is 
completely naked except at the root. The feet are precisely as in the 
other species of this division of the genus. (Dr. Le Conte.)
