The length of this species is fourteen inches and a half. The beak, the naked membrane, and feet are blackish; the circle of the eye is rather white, and the iris inclining to red. The general colour of this species is also white, with a primrose-yellow tint on the wings and tail, as well as a spot of the same colour under the eyes. The tuft, which is pointed, and composed of soft thread-like feathers, is of lemon-colour. It comes from the same country as the preceding, to which it yields neither in elegance, intelligence, docility, nor mildness. It is fond of caresses, and returns them with pleasure: all its motions are equally full of grace, delicacy, and beauty. There are two varieties of this species, which only differ in size. THE GREAT RED-CRESTED COCKATOO. Psittacus Moluccensis, LINNÆUS; Kakatoes à huppe rouge, BUFFON; Der rothäubige Kakatu, BECHSTEIN. This species is a little larger than the common cockatoo, its size being almost equal to that of the red and blue maccaw. Its beak is bluish black, the membrane black, the circle of the eyes pearl grey, and the iris deep red. The feet are lead colour, the nails black. White, tinged with pale rose-red, is the prevailing colour; the tuft, which falls back on the head, is very large, most of the feathers being six inches in length; of which the under side is of a beautiful orange. In the side tail feathers, from the base to the centre of the interior beard, the colour is primrose-yellow; the under part of the pen-feathers has a tint of the same. OBSERVATIONS.--This beautiful bird has a noble air; and, though often tamed, it is rarely so caressing as the common cockatoo; its cry, like that of the other species, is its own name; it also cries "_tertingue_" very loud, and like a trumpet, and imitates the voice of several animals, particularly the cackling of fowls and the crowing of cocks. When it cries it flaps its wings. Though a native of the Moluccas, it is neither delicate nor difficult to rear. THE RED-VENTED COCKATOO. Psittacus Philippinarum, LINNÆUS; Le petit Kakatoes des Philippines, BUFFON; Der rothbäuchige Kakatu, BECHSTEIN. This species, the size of the grey parrot, is but thirteen inches in length. The beak is white, or of a pale flesh colour, and grey at the base; the circle of the eyes is yellowish-red; the feet are of a silver-grey; the general colour of the body is white; the head is ornamented with a tuft, in which there is nothing remarkable but its raising it in the form of a shell. OBSERVATIONS.--It is a native of the Philippines. Its beauty and great docility are its chief merits; for it cannot speak, and it also appears of a jealous nature, being angry when it sees the other parrots caressed, and making the unpleasant cry of "_aiai, miai!_" but never "_cockatoo_." THE BANKSIAN COCKATOO. Psittacus Banksii, LINNÆUS; Le Kakatoes Noir, BUFFON; Der Banksche Kakatu, BECHSTEIN.
