In heraldry, a lion in a walking position with its head turned to full face is called what?

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.

The typical heraldic leopard differs from the natural leopard (Panthera pardus) in that it has no spots and often has a mane, but is generally similar in appearance to a heraldic lion, other than its attitude. In the Middle Ages, leopards were thought to be a crossbreed between a lion and a pard.
