fossze ; and in the reduction of the articular pits on the costal borders to three on each 
side, closely conforms to the type of that instructive bone, in the Palaptery« (Dinornis), 
described in pp. 124 and 196, 
I have refrained from entering into closer descriptive details of the skeleton of the 
Dinornis elephantopus, because only the plates can convey an adequate idea of its extra- 
ordinary proportions to those who have not seen the original itself. 
The specimen, as now articulated, stands in the first compartment of the Palzontological 
Gallery of the British Museum. The articulated hind-limbs of the Dinornis robustus 
—a possible variety of D, giganteus—are placed on each side, as in Pl. LXI., to illus- 
trate the characteristic proportions of the two extinct species. 
The drawings from which the plates have been engraved were taken from two 
successful photographie views, corrected, as to the relative size of the parts, from the 
skeleton itself: I am much indebted for the care and skill which Mr. Erxleben has 
bestowed on this complex subject. 
The first evidence of the Dinornis crassus reached me from a turbary deposit at 
Waikawaite, in the Middle Island; it formed part of the collection there made by 
Mr, Earl, I have never received any evidence of this species of Dinornis from the 
North Island. 
In like manner the bones of the much larger bird, which I have called Palapteryx 
robustus and Dinornis robustus, and which I was formerly inclined to regard as not only 
specifically but generically distinct from Dinornis giganteus, appear to be peculiar to 
the Middle Island; or at least have not, hitherto, been found in any locality of the 
North Island. 
The richer series of illustrations of both Dinornis robustus and Din. crassus in the 
collection of Mr. Walter Mantell are from localities in the Middle Island; and the 
abundant illustrations of Dinornis elephantopus are exclusively from one locality in that 
island: they were obtained at Ruamoa, three miles south of Oamaru Point, or that 
called the “First Rocky Head” in the New Admiralty Map, This fact might give 
rise to the idea that the original range or locality of Dinornis elephantopus had been 
a restricted one; unless, at the period when the species flourished, the geographical 
extent of the Middle Island of New Zealand was widely different from what it now is. 
Yet Mr. W. Mantell has obtained strong, if not unequivocal, evidence that Dinornis 
elephantopus and Din. crassus existed contemporaneously with Maori natives in that 
island. The bones described in the foregoing pages are in a recent and most perfect 
condition, ‘They retain the usual proportion of animal matter, and have undergone no 
mineral change. 
They were discovered under circumstances closely resembling those described in a 
previous Memoir, p. 220, under which the femur of Dinornis gracilis was found in 
the North Island, by Mr. Cormack. Remains of native ovens, with the baking stones, 
were not far from the chief collection of bones of Dinornis elephantopus, discovered
