An Amphiptere (also called Amphithere, Amphitere, or Phipthere; meaning bi-winged, two-winged) is a type of winged serpent found in European heraldry. Amphipteres generally were said to have light-colored feathers like a sunrise, a serpentine body similar to a lindworm, bat-like wings with feathers covering most of the forearm and often greenish in coloration, and a long tail much like a wyvern's. Others are described as entirely covered in feathers with a spiked tail, bird-like wings, and a beak-like snout. Even more uncommon is the description of one with legs.
