Containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland and lower California, with which are incorporated General ornithology: an outline of the structure and classification of birds; and Field ornithology, a manual of collecting, preparing, and preserving birds. Birds; Birds; 1887. 170 GENERAL , PmJ!^ the gist of dromaognathism; it is exhibited in several ways, (n) In Struthio alone, fig. 75, the very short vomer, home upon the rostrum, articulates neither with palatines uor with ptery- goids, but with the maxillo-palatines ; and the palatines, which are remote from the rostrum, advance beyond the maxillo-palatines, as in must birds, (h) In Rhea, the vomer is as long as usual in birds, and articulates behind with the palatines and pterygoids, but does nut join the maxillo-palatines in front ; the short palatines uuite with tlie inner and posterior edges of the thiu fenestrated maxillo-palatiucs. (c) In CasuariKs aud Drointriis (cassowary and emeu), the long vomer articulates behind with the palatines and ]iterygoids, aud unites in fnmt with the maxillo-palatines; these are flat, imperforate, and solidly joined to the premaxillte; the palatines are short, (rf) The extinct Diiiornis had flat imperforate maxillo-palatine plates uuiting solidly with the jiremaxilUe, and jirobably witli the vomer, as in Lromcriis. (e) In Apteryx, the long vomer unites with palatines and pterygoids behiud : short broad palatines suture oliliquely with ilat imper- forate maxillo-palatine plates, which uuite both with jiremax- illary aud vomer.
