American Deer, Genus _Mazama_.--Lateral metacarpals as in _Rangifer_; antlers very variable in size, forming a marked angle with the plane of the face, without a brow-tine; when consisting of more than a simple prong, dichotomously forked, frequently with a sub-basal snag, and always with the lower prong of the fork projected from the front edge of the beam, in some cases the lower, in others the upper, and in others both prongs again dividing; tail long; tarsal gland generally present; metatarsal gland very variable, both as regards presence and position; vomer dividing the inner aperture of the nostrils in the skull into two distinct chambers.
