Leopard (heraldry)

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.

[2] 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.

[3] Arthur Charles Fox-Davies wrote in 1909 that the distinction between lions (which were constantly rampant) and leopards (which were necessarily walking) originated in French heraldry and was brought into English heraldry along with so much else of English language and custom deriving from French traditions.

But "the use of the term leopard in heraldry to signify a certain position for the lion never received any extensive sanction, and has long since become obsolete in British armory," though the distinction is still observed in French blazon.
