. Annals of the Carnegie Museum. Carnegie Museum; Carnegie Museum of Natural History; Natural history. Shukkldt: {)sik(Ma)gy oi'- ihk 59 expanded, which expansion includes the graceful canopy that arches over the unpierced pneumatic fossa. A deep notch divides this from the articular facet or heatl for the glenoid cavity. The radial crest is well developed and bent outwards almost at a right angle with the \cili(al plane of the bone, when viewed in a position of rest. Should a section of l)e made, the figure would be very nearly circular; it becomes triedral proximally and roughly ellii)tical towards the distal end. In this latter region, above the external condyle, an " epicondylar" jjrocess is develoijed ; and this process is developed in a greater or less degree in all shore-. ¥\r,. 21. Riglil humerus of Xiimcuitis loiigirosfris, anconal aspect ; natural size. birds. Its apex is intended for muscular attachment. There is a well- marked fossa just proximad to the distal articular tubercles of the humerus. \'iewed from above, the .shaft of the 11//la is seen to have a long, gentle curve, extending from one end of the bone to the other, being the greatest near its proximal extremity. The papillee for the quill-butts along the shaft are quite distinct in this bird, and still more so in the Oyster-catcher, where they present the unusual condition of being narrow and oblong in shape, and placed, as it were, oblicjuely on the shaft. To the inside of these a secondary row is seen, running down the shaft longitudinally. These little pro- tuberances are scarcely perceptible in the Phalaropes or in Triuga. The radius of N. longirostris does not exhibit so much of a curve in its shaft as its com{)anion in the antibrachium, though it is gently bent throughout its length. A concavity is scooped out of its shaft near the head, over which tendons pass in life. The carpus contains the two free bones ordinarily found there in adult birds, articul
