_Dinornis crassus_ Owen, Trans. Zool. Soc. III, p. 307 (1846--partim).
_Emeus crassus_ Reichenbach, Nat. Syst. der Vög., p. XXX (1850).
_Syornis crassus_ Hutton, Trans. N.Z. Inst. XXIV, p. 132 (1892).
This species has led to much confusion, owing to Professor Owen having
associated with the real portions of _crassus_ in his possession bones of
_elephantopus_, _ponderosus_ and _struthioides_. The type came from
Waikouaiti.
Habitat: Middle Island, New Zealand.
