Diagnosis

Reference	Diagnosis
L. Furlong Eustace 1946 (Breameryx)	Premolars more hypsodont than in Capromeryx; P 3 with singleenamel indentation on lingual side of crown. Alveolar measurement of cheek teeth(P 2 -M 3 inclusive) shorter than in the Nebraskan antelope. Third or posterior lobein M 3 relatively longer; ramus of mandible not so elongated as in Capromery:x fur-cifer. Skull relatively broad in comparison with length; orbits large and tubular;bullae strongly expanded. Horn cores consisting of a short, spurlike front prongand a distinctly taller hind prong, which is rounded in cross section. The two prongsare closely situated, end in points, and arise from a common base or pedestal. Thelatter outgrowth of the frontal is above the laterally expanded supraorbital rim. Limb elements slender and elongated.
