The GIANT STORKS (Mycteria) are comparatively tall birds, with a slender body, long neck, and rather large head; the very long beak is almost straight or very slightly curved, and furnished with a saddle-shaped cere at its base, and skinny knobs or appendages beneath. The tarsi are high, and the toes short; the long and rounded wing has its third quill longer than the rest; the tail is straight, and of medium length. The sexes are almost alike in size. The young are less brightly coloured than the adult birds. Of the three species of Giant Storks with which we are acquainted, one occupies Africa, another Australia, and the third South America; these birds nearly resemble each other in their general appearance and habits.

THE SENEGAL JABIRU.

The (Mycteria Senegalensis) is a large powerful bird, with the head, throat, upper wing, shoulders, and tail of a glossy metallic black; the rest of the plumage is of dazzling whiteness. In the beak the upper mandible is of very pale tint for about three inches from its base, and the under one for about one inch and a half; then comes a bar of black for about three inches, and from that to the end the bill is reddish, increasing in depth of colour to the bright vermilion tip. On each side of the upper mandible is a large semi-oval and transparent space, which at the back part is continued upwards in a curved direction across the fore part of the eyes and over the nostrils. Beneath the base of the bill, just at the beginning of the feathery part, are two very small, pear-shaped, pendent, yellowish wattles adhering by very small necks. The bare portions of the face are reddish, the eyes and eye-rings yellow; the broad movable cere is also yellow, surrounded by a narrow border of black feathers. The tarsi are brownish grey, the knee and toe-joints dull red. This species is fifty-six inches long, and ninety-two broad; the wing measures twenty-five, and the tail ten inches. In the young, all the dark parts of the plumage are brownish grey, and the under side dirty greyish yellow. Their eye is brown, and beak blackish red; the appendages beneath the beak are not developed.

This fine bird is a native of Africa, where it principally frequents the regions watered by the White and Blue Nile, but is also seen in other parts of the continent. It lives in pairs, and occupies the shores of rivers, or the vicinity of lakes, tanks, and morasses, only quitting these for a short period during the rainy season; occasionally, but very rarely, it is met with near shallow salt water. Upon the ground it moves with a certain stately grace, and, owing to its length of leg, appears taller than it really is. Whilst in the air its fine black and white pinions render it a most striking and beautiful object. Unfortunately for science, the Senegal Jabiru is so extremely shy as to render any close observation of its habits almost impossible. In the stomachs of such specimens as we examined, we found reptiles and beetles; it also eats fish, and, according to Rüppell, has been seen upon carrion, but whether the bird was eating the putrid flesh, or merely gleaning off the insects that were feasting thereon, is at present uncertain. Gurney states that the pairs remain united for life, and entertain each other by a most strange dancing kind of performance. Should one of them die, the survivor does not soon mate again. It is probable that this species breeds on trees, and builds a nest resembling that of the Stork.

THE JABIRU.

The (Mycteria Australis) has the head and neck of a deep glossy green, shading into purple and violet at the back of the head; the large wing-covers, scapularies, lower part of the back, and tail are glossy green, tinged with a golden lustre; the rest of the plumage is pure white. The beak is black, the eye deep hazel, and the leg bright red.

This species has a wide range over Australia, and at the time of its first colonisation was seen as near to Sydney as Botany Bay; in the neighbourhood of the Hunter River, it is occasionally met
