"Dromaeognathous skull of a tinamou (Tinamus robustus); copies by Shufeldt from Huxley. Letters as before; Mxp, maxillo-palatine. The tinamous, Dromaeognathae "have a completely struthious palate"; vomer very broad, uniting in front with broad maxillo-palatine plates as in Dromaeus; behind articulating with posterior ends of palatines and anterior ends of pterygoids, both of which are thus prevented, as in all Ratitae, from any extensive connection with the rostrum; basipterygoid processes springing from body of sphenoid, not from its rostrum, articulating with pterygoids very near the posterior or outer ends of the latter; head of quadrate with a single articular facet, as in Ratitae." Elliot Coues, 1884
