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 mid-.shaft 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-

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, articulating after the usual manner. 



All of the Limicokc, so far as I have examined them, are endowed 

 with a remarkably long hand. If we allow the bones of the carpus to 

 be added to it, its length in the Sickle-bill is fully equal to that of the
