. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. PELVIS. 1G9 coccyx has five pieces in the Pheasant and Turkey, and, in the latter, is said not to be perforated for the spinal chord. In the Pea- cock there are eight pieces, and the terminal bone is a horizontal oval plate to support the radiating feathers. In the tailless Manx va- riety of the common Fowl, the coccyx is borted into a single tubercular projection. The Uia and ilia-sacral ossifications are broad, and the isckia long, divergent, and widely expanded posteriorly into a very broad sacro- sciatic element, much hollowed out in the pelvic cavity, and enclosing a large foramen (seefig. 105. /). This is especially marked in the Crown Pigeon, Bustard, Crested Curassow, and (Juan. The pubes are long, and generally unite with the ischia to complete an elongated obturator hole (/?). In the Dove, the pubes and ischia are united in their whole length, and the foramen is obliterated, while in the Crested Guan and Trumpeter it is subdivided into an anterior and posterior portion, as in the Ostrich and Rhea. In the Grallalores the sacrum is broad, and composed of from ten to twelve pieces, but in the Oyster Catcher there are fifteen. In the Snipe the transverse processes are more or less separated. The coccyx is in seven or eight pieces. The ilia and ischia are shorter and broader than in the Natatorcs, the former being placed more parallel to the spine, crossing it at about 165° ; and the latter forming an i/io- ischial angle of 160°. The inter-do tyloid dis- tance is very great, especially in the gigantic Crane, but in the Stork and Bittern the whole pelvis is smaller and more contracted. The pubes are long, diverging, and parallel to the ischia, especially strong in the Aptenodytes ; and enclosing often a large obturator foramen by coalescing with the ischia. In the Stork, Ibis, and Flamingo, however, there is no such union. In the Scansores, the sacrum of the Parrot is short and very bro
