The configuration of the various processes of thesebones is manifold, and of great taxonomic importance, as has beenexhaustively shewn by Prof. Fiirbringer, in whose Untersuchungenzur Morplwlogic und Systcmatik der Vogel about one hundred figuresof this articulation in different Birds are given. The Coracoid is one of the most characteristic bones of theornithic Skeleton. At its upper end is the Acrocoracoidal pro-cess, on the inner surface of which the proximal portion of theclavicle nearly always rests ; but more important is the Prsecora-coidal process, of variable size and shape, arising from the innersurface of the neck of the bone, and the remnant of an originallyindependent element, the PrjEcoracoid—a bone which is almosttypically complete, although soon fused at either end with the SKELETON 857 Cki. Coracoid, in the Ostrich alone of Birds. This prsecoracoidal pro-cess is of some taxonomic vahie,^ and near its base is either a notchor a small foramen for the passage of the nervus supracoracoideuswhich supplies the muscle of the same name, and indicates theboundary between Coracoid and Prsecoracoid. A strong ligament,sometimes partly ^j^,„ ossified, frequentlyextends along theinner margin of bothcoracoid and pra3-coracoid to the ros-trum of the most Birds theright and left Cora-coids do not toucheach other, but insome groups theymeet, as in certainTuhinarcs, Gathar-ticlx, some Falcon-idx, Laridse., Opistlio-comus, some Gallinx, Bucerotida, Upupa and Trogonidx, while in someother groups one overlaps the other, the right lying A^entrally uponthe left, as Dromxus, Ichthyornis, Apatornis, certain Tuhinares, someSteganopodes, Ardeidx and Ciconiie, Phcenicopterus, some Falconidx,some Gallinx, Musophaga, Striges and Meropidai.
