_Pachyornis inhabilis_ Hutton, Trans. N.Z. Inst. XXV, p. 11 (1893).
Differs from _ponderosus_ by having the great inward expansion at the
distal end of the tibio-tarsus. This expansion has induced some
ornithologists to separate the species of _Pachyornis_ into two
genera--_Euryapteryx_ and _Pachyornis_--but I do not think this expansion
of sufficient importance to warrant generic separation.
Habitat: Middle Island, New Zealand.
