IBIS. Under the generic name TANTALUS (Encycl.), we have described, after Mr Bruce, a bird which he found in Abyssinia, and concluded to be the sacred ibis of ancient Egypt. M. Vaillant, during his last travels in Africa, found, in some lakes near the elephants river, a bird very different from Mr Bruce's, which he considered as belonging to the same species; and which he describes thus: It is three feet in height. Its head and throat, which are extremely bare, are covered with a skin of the brightest red, terminated by a band of a beautiful orange, which separates the naked part from that covered with feathers. The upper part of the wings, having broad stripes of a fine violet colour, agreeably shaded, is bordered by a white band of feathers, the thick and silky beards of which, separated from each other, have a perfect resemblance to a rich fringe. The quills of the wings and tail are of a greenish black, which, as it receives the light in a more or less oblique direction, assumes the appearance of violet or purple. The rest of the plumage is of a beautiful white. The bill, which is long and somewhat crooked, is yellow; as are the feet. This bird belongs to the genus of the ibis, of which we are already acquainted with several species.
