68 ODONTOCCELUS. 
In the countries south of the Mexican and United States boundary 
only diminutive members of the CeRvip# are found, and but few 
species even of these. Most of them represent in miniature the 
White-tailed Deer of the United States, similar in color and style of 
antlers, though in certain species there is a tendency to a darkening 
of the coat and to the disappearance of the metatarsal gland and 
tuft, which, indeed, in some are entirely wanting. The darker color 
is merely characteristic of animals living in humid climates, but the 
absence of glands is not so easily explained. 
Fam. Il. Cervidz. Deer. 
Antlers solid, always present on the male, sometimes also on the 
female; first molar in upper and lower jaw brachyodont; lachrymal 
bone prevented from articulating with the nasals by an extensive 
antorbital vacuity; lachrymal duct with two orifices at or inside rim 
of orbit; upper canines often present, sometimes greatly elongated 
in the male; lateral hoofs nearly always present on all the feet; no 
gall bladder.
