Then the supraoccipital never has a very strongly developed median prominence, and the temporal fossae are comparatively short. The mandible may be readily distinguished from that of the other genera by the low position of the inner aperture of the dental canal, which pierces the bone obliquely to join the small lateral vacuity.

Type of the genus: Pachyornis elephantopus (Owen).

Number of species: 8.
