PALAEOCORAX FORBES.

This genus is founded on cranial characters: Basipterygoid processes of parasphenoid present but rudimentary. The vomer broad, flat, and three-pointed in front. Maxillaries anchylosed to the premaxillaries, the latter anchylosed to the expanded ossified base of the nasal septum. The ossified mesethmoid stretches backward and is lodged in the concavity of the upper surface of the vomer, so that it presents a form intermediate between the complete aegithognathous forms, such as Corvus, and the compound aegithognathous forms, such as Gymnorhina, in which desmognathism was superadded by "anchylosis of the inner edge of the maxillaries with a highly ossified alinasal wall and nasal septum" (Parker).
