Terrestrial or arboreal granivorous, frugivorous, or phytophagous 

 birds with palate scbizognathous, nasals schizorhinal or (in Gouridse) 

 pseudo-holorhinal; dorsal vertebrae heteroccelous (their ankylosis 

 Galline); subclavicular processes present; caeca nonfunctional, and 

 young gymnopsedic and nidicolous. 



Basipterygoid processes present (except in Suborder Raphi) and 

 placed medially; angle of mandible neither produced nor recurved, 

 but abruptly truncated; subclavicular processes present; cervical ver- 

 tebrae 14-16; spina interna sterni usually present but small, some- 

 times absent; spina externa present; metasternum usually 4-notched 

 (the inner pair of notches sometimes converted into foramina), 

 sometimes (in genus Geophaps) with only two notches, the sternum 

 very narrow; 6 furcula well-developed (except in Suborder Raphi), 

 U-shaped, without hypocleideum; basal end of coracoids in contact 



°In the "Key to the Orders of the Subclass Ornithurse" on pages 8-12 of Part I 

 of this work, following Puerbringer and Gadow, the Oolumbiformes are merged with 

 the Charadriiformea (page 11); but the Pigeons, together with their nearest allies, 

 the extinct Dodo and Solitaire, are so sharply circumscribed a group that, like the 

 Parrots, they seem to be entitled to rank as a distinct Order. 



& When there are four notches the lateral processes are much shorter than the inner 

 ones, as in the Order Galliformes.
