CNEMIORNIS OWEN.

Skull short and massive, with beak rounded and stout. Carina of sternum aborted. Limb-bones short and very stout, the ulna being shorter than the humerus, and having very prominent tubercles for the secondaries; cnemial crest of tibia greatly developed. No foramen between third and fourth trochleae of tarso-metatarsus. Spines of dorsal vertebrae tall. The power of flight was absent. The chief differences from Cereopsis were the presence of extra pre-sacral vertebrae, so that two only instead of three ribs articulate with the sacrum; and an elevated pent-roof arrangement of the ossa innominata, which indicate more decided cursorial habits.
