With regard to the construction of the feet it may be further remarked, that the length of the inner and outer toes is nearly equal, as in the Cassowary; but the middle toe, which in the Cassowary is one-third longer than the other digits, in the Moa scarcely exceeds in length by one-fifth, the inner and outer toes. The ungueal segments are very large, being equal to one-third the length of the toes. The phalangeals are relatively much shorter than in the Cassowary and Ostrich, and wider than in the former, and more arched than in either of these living struthious birds. In the metatarsal the presence of the three elements whose fusion constitutes the bone, is strongly marked; there does not appear to be any certain indications of a posterior or hind toe, though Professor Owen imagines he has detected feeble traces of a fourth digit: in that case the bird to which my specimens belonged, would be termed _Palapteryx_. The crania found by Mr. Walter Mantell at Waingongoro, and figured and described by Professor Owen in the Zoological Transactions (Vol. III., Plates 52, 53, 54, 55), as Dinornis and Palapteryx, must have belonged to birds of comparatively small stature. The skull with the adze-like upper mandible, and the enormously-developed _basi-occipitals_ and _basi-sphenoids_ (_Dinornis_, of Professor Owen, Plate 53), was found associated with many vertebræ of the neck and back, and bones of the leg, of the same bird; and these my son states indicated a height of from six to seven feet. The skull and the rest of the skeleton were found imbedded in sand, and lying in their natural relative position; unfortunately, all these precious remains, except the cranium, were destroyed by a sudden rush of the natives to seize upon the exhumed relics! It therefore yet remains to discover the cranial type that characterized the colossal forms at present known only by other parts of the skeleton.]
