The inferior orifice of the supormaxillo-dentul canal or infraorbital foramen is pierced above the first molar tooth. There is no fissure for the formation of the palatine canal. The cavity of the sinus is more spacious than in the Horse, and is prolonged (in the Ox only) between the two laminae of the palatine roof. There is no alveolus for the tusk. 8.
