The nasal cavity communicates with the mouth by the choanae or posterior flares, situated between the palatine process of the maxillary, the palatine and the vomer.

The palatines are long, always fused anteriorly with the premaxilla, and fre quently with the maxillo-palatine processes; posteriorly they slide upon the presphenoidal rostrum, and articulate in most birds with the pterygoids; they form the greater part of the palatal roof and border the choanae or inner nares.

The posterior nares or choanae open far behind in the roof of the mouth, in recent forms within the pterygoids.
