Dromaeognathae have a struthious palate, with a broad vomer meeting in front the broad maxillo-palatal plates, while behind it reaches the pterygoids.
The Carinatae are divided, according to the formation of the palate, into four " Suborders," and named (i.) Dromaeognathae, (ii.) Schizognathae, (iii.) Desmognathae, and (iv.) Aegithognathae.'
The Dromaeognathae resemble the Ratitae, and especially the genus Dromaeus, in their palatal structure, and are composed of the Tinamous (q.v.).
Huxley; hence his term Dromaeognathae for the Crypturi.
The group from the resemblance of its palatal characters to those of the Emeu, Dromaeus, he called Dromaeognathae, but it is now more usual to place them in a separate order, the Tinamiformes.
