The leopard in heraldry is traditionally depicted the same as a lion, but in a walking position with its head turned to full face, thus it is also known as a lion passant guardant in some texts, though leopards more naturally depicted make some appearances in modern heraldry. The Oxford Guide to Heraldry makes little mention of leopards but glosses leopard as a "term used in medieval heraldry for lion passant guardant. Now used for the natural beast." Another name for this beast is the ounce.
