Dinornis didiformis Owen, Trans. Zool. Soc. III, pl. 24 (1846), part.

Euryapteryx exilis Hutton, Trans. N.Z. Inst. XXIX, p. 552, pl. XLVIII, Fig. C (1897).

Differs from E. crassus in the tibia being more convex on the anterior surface. The skull, among other differences, has a very slight frontal rising to the cranial roof, as opposed to the very conspicuous one in the remaining species. The type is a nearly complete skeleton in the Wanganui Museum. For full description see Hutton, l.c.

Habitat: North Island, New Zealand.
