DINORNIS GIGANTEUS OWEN.

 D. validus Hutton, Trans. N.Z. Inst. p. 111 (1892). 



THIS is, as regards size, one of the more variable forms in the tarso- 

 metatarsus, while the tibio-tarsus is remarkably constant. The 

 tibio-tarsus is almost invariably 35 inches in length, while the tarso- 

 metatarsus varies from 17*5 to 19 inches in length. 



The type of D. giganteus Owen is from Poverty Bay ; the type of 

 D. validus is from Glenmark. 



Habitat : North and Middle Islands, New Zealand.

DINORNIS INGENS OWEN.

 D. potens Hutton, I.e. p. 115. 



INGENS shows considerable variation in size, but the inter-gradation 

 is so complete that it seems impossible to retain the four species 

 ingens, firmus, potens and robustus, which Captain Hutton admits. 

 This form was widely distributed over the North and Middle Islands. 

 The type skull of P. robustus came from Timaru, the type of firmus 

 from Wanganui, that of ingens from Poverty Bay, while that of potens is 

 quoted from the East side of Middle Island, without specific type locality. 

 Habitat : North and Middle Islands. 



The plate of this species was reconstructed by Mr. Frohawk from the 

 skeleton and feathers in my museum, and the feathers found with the 

 skeleton now in the York Museum. The only criticism that might be made in 

 connection with this picture is that the feathers are drawn a little too much 

 like those of Apteryx australis, but this is not of any consequence, as the Moa 

 feathers in the Tring Museum and elsewhere vary considerably in appearance, 

 though being more or less coloured like Apteryx feathers. 



There is an almost perfect skeleton in the Tring Museum.
