The most extraordinary feature is unquestionably the former existence of the gigantic Dinornithes or moas and, another family of Ratitae, the weird-looking kiwis or Apteryges, which are totally unlike any other existing birds.
Order Apteryges.-Four toes.
Fiirbringer, however, separated Apteryx with Dinornis from the rest, combining his "Apteryges" with Crypturi and Ga Ili as Alectorornithes, the latter being practically A.
Orders: Struthiones, Rheae, Casuariae, Apteryges, Dinornithes, Aepyornithes.
The most obvious feature the Apteryges afford is the presence of a back toe, while the extremely aborted condition of the wings, the position of the nostrils - almost at the tip of the maxilla - and the absence of an after-shaft in the feathers, are characters nearly as manifest, and others not less determinative, though more recondite, will be found on examination.
