PALAEOCORAXFORBES.
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).
PALAEOCORAX MORIORUM(FORBES).
- Corvus moriorum Forbes, Nature XLVI p. 252 (1892).
- Palaeocorax moriorum Forbes, Bull. B.O.C. I p. XXI (1892).
Dr. Forbes says this bird is of about half the size again of a Corvus cornix. The principal characters are cranial, and the same as those of the genus.
Habitat: Chatham Islands, and possibly the Middle Island, New Zealand.
Many skulls and bones in the Tring Museum.
PALAEOCORAX ANTIPODUMFORBES.
- Palaeocorax antipodum Forbes, Ibis 1893, p. 544.
This is said to be distinguished from P. moriorum by its considerably smaller size. Habitat: North Island, New Zealand.
