RUMINANTIA—CERVINAE—CERVUS MEXICANUS. 655 
Much still remains to be done in defining with precision the characteristics of the smaller 
deer of America, and in the discrepancy of descriptions of authors there is some doubt as to 
whether the present specimen is really the C. meaicanus or not. It agrees sufficiently, however, 
with this animal, as described by Lichtenstein, Wagner, and other writers, and in its geo- 
graphical position is not very remote from the region assigned by these authors to the Mexican 
deer. The new Gadsden boundary line between the United States and Mexico probably marks 
its extreme northern range. Southward it extends through the wooded mountain region of 
Mexico, beyond the city of Mexico. ; 
The horns of this deer are described as resembling the C. virginianus, but, perhaps, with 
fewer points. The following measurements of a buck are taken from Lichtenstein :

The female is smaller than the male. 
The characteristics which distinguish this species from the (. virginianus will also serve to 
separate it from the C. leucurus, such as its different color, very small size, short tail, &c. 
They agree in the slightly marked character of dusky band across the end of the lower jaw.
