RUMINANTIA CERVINAE CERVUS AIEXITANUS. 



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. mexicanus 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 O. 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.
