The beak is large, strongly but bluntly toothed, and having the ridge of the upper mandible powerfully hooked and projecting. The cere is short, and its margin curved like the letter S. The eyes are surrounded by a broad bare circle; the bluntly-pointed wings reach to the middle of the tail, the latter being of tolerable length and formed of rounded feathers, of which the three exterior on both sides are shortly graduated; the legs are weak, and the toes long. The plumage is on the whole extremely rich, of a pale yellowish-grey upon the head; the exterior margin of the forehead is of a brown colour; the crest is composed of dull blood-red feathers, edged with sky blue. The plumage on the back is light green, somewhat darker in the middle than on the sides, and the feathers on the lower part of the body are, as far as they are visible, blood-red. The sides of the cheeks and the throat are of a brownish tint; the primaries quite black, and the secondaries similarly coloured on both sides. The tail is bluish on its upper surface, and black underneath. Burmeister gives the length of this rare and beautiful species as being fourteen inches, five and a half of which belong to the tail; the wing measures seven inches from the shoulder to the tip. As far as we know at present, this bird prefers dwelling in the wooded district near Guiana and the River Amazon. Spix found it at Villa Nova, on the river above-mentioned. Schomburghk mentions it but twice. He says that he met with it on the Rupununi, and also in the huts of the Warrau Indians; but though he saw numerous flocks of these magnificent birds enlivening the palm-trees of Sawari, and greeting passers-by with piercing cries, and thus had abundant opportunities for making observations, he tells us extremely little about them. "When angry," he informs us, "this bird is without doubt one of the most beautiful of the parrot race, as it then raises the brilliantly tinted feathers on the back of the neck, until they stand up perpendicularly, thus forming a flowing circle round the head." The settlers call it "Hia," which word is supposed to resemble its cry. From the same writer we learn that this species inhabits the lower woods, approaching the settlements with confidence, and although easily tamed, is weakly and unteachable. It makes its nest in the holes of trees, and lays from two to four eggs. THE DWARF PARROTS.
