 shown in plate 10, figure 21 and plate 16, figure 32; its carpo- 

 metacarpus in plate 10, figure 22, and its sternum in plate 11, figure

8 Superior aspect of the skull of Neophron percnop- 

 terus. Adult ; mandible removed ; reduced about one fourth. 

 Other views of this skull are given in figure 10 of plate 6; figure 23 

 of plate 10; while the trunk skeleton which came from the same bird 

 is shown in figure 27 of plate 12, and figure 30 of plate 14. In its 

 skull at least, Neophron comes nearer Catharista than it does 

 Cathartes. The circular opening in the parietal region of this skull, 

 seen in the figure, is a shot hole.
