The name of the genus Campephaga being unfortunately pro-occupied, it is impossible for the family to be called after it. The next oldest genus is Pericrocotus, and the family will therefore have to be known by the above name. The characteristics are those of the Laniidae but the feathers of the rump have stiffened spiny shafts. As a whole, also, the wings are proportionately longer and more pointed and the legs and feet are comparatively weaker.
