Alleˊrions [in Heraldry]

are small Birds painted without Beak or Feet, like the Martlet or Martinet. Others say, they are like Eagles without Beak or Feet, so called, because they have nothing perfect but the Wings; that they differ from Martlets, in that their Wings are expanded and the Martlets are close; and also that they are not represented facing as the Allerions are, as in the Figure.
