. The bird, its form and function . the head, dotted with tubercles of the most bril-liant orange, while a long tube-like wattle, also tippedwith orange, dangles down over the beak. The wattles,or caruncles, of the Bell Bird are interesting as being con-nected with the windpipe in such a way that they becomeinflated with air when the bird utters its wonderful note. In the White Ibis the face only is bare, in the spoon-bill the head and face, and the whole head and neck inthe Marabou Stork; the effect of this condition in thelatter bird being heightened by the enormous pouchwhich hangs suspended from the neck. The same is trueof the Adjutant. A close inspection of the neck of one of these storkswill show that, while ordinary feathers are absent, thereis a scanty covering, here and there, of what looks like soft,curling ringlets of chestnut hair. The resemblance isabsolutely perfect, and no naturalist in the world, if shownone of these locks, would say that it came from a birdand not from one of the hair-covered mammals!.
