Pard
In the early days of heraldry the leopard was a little known animal and was characterised by a catlike walk in contrast to the lions more aggressive stance. The lion passant guardant was considered a lion behaving like a leopard and was indistinguishable from the leopard by early heralds, who never drew it spotted and who sometimes termed it as Leopardé. In fact, the Royal Arms of England were originally emblazoned Gu, three leopards in pale or. Also called Ounce

If no part of the neck appears, and the position of the head is guardant, that is, when caboshed, it should then be blazoned a leopard’s face, omitting the word guardant, which is implied.

A leopard’s face jessant-de-lis
Leopards’ heads thus
borne, were often, though improperly reversed by ancient heralds, which should
not be done unless particularly so described in the blazon.
