The TRUE PARADISE ALCYON (_Tanysiptera sylvia_), one of the most refulgent members of this group, is bright blue on the crown of the head, wings, and two outer tail-feathers; the cheek, back of the throat, and mantle are black; and a triangular patch between the shoulders, the rump, and the two centre flowing tail-feathers pure white. The entire under side is brownish red; the beak and foot are bright red. The body measures ten inches; the wing two inches and two-thirds, and the tail two inches and three-quarters. Gould tells us that this beautiful bird, which has at present only been met with at Cape York, on the northern coast of Australia, never alights upon the ground, but is usually seen perched upon a bare twig or parasitical plant, from whence it darts upon its insect prey, always returning at once to its perch. Its flight is remarkably rapid. The cry of this species, which resembles the syllables "wee-wee-wee," is usually uttered when the bird is stationary. Owing to its extreme timidity, the _Tanysiptera sylvia_ is extremely difficult to obtain; indeed, the sportsman may follow it for an hour at a time without the chance of a fair shot. According to the natives, the three white eggs laid by the female are deposited in ant-hills. Two other nearly allied species, the _Tanysiptera dea_ and the _Tanysiptera nympha_, inhabit New Guinea, the Moluccas, and Philippine Islands. * * * * * The SAW-BEAKED ALCYONS (_Syma_) have a long, thin beak, broad at its base, and compressed at its sides, furnished down two-thirds of its length with numerous strong teeth-like appendages; the upper mandible projects beyond the lower portion of the bill, and terminates in a sharp, slender tip; in the short wing the third and fourth quills are of equal length, and longer than the rest; the tail is of medium size, and very decidedly rounded. THE PODITTI. The PODITTI (_Syma flavirostris_), one of the two species of Saw-beaked Alcyons with which we are acquainted, as inhabiting Australia and New Guinea, is of a brownish red on the top of the head, nape, ear-covers, and sides of throat; the back and wings are dull green, the rump and tail greenish blue, the front of the throat and lower belly yellowish white, and the remainder of the under side yellowish brown; the head is almost encircled by a narrow black line; the pale red bill is blackish brown at its culmen. This species is seven inches and one-sixth long; the wing measures two inches and two-thirds, and the tail two inches and one-sixth. * * * * * The SLUGGARDS (_Agornithes_) are remarkable for the bristle-like feathers that form a kind of beard; an unusually delicate skin, in which the broad, soft, downy feathers grow but loosely; and still more for their indolent and dreamy disposition. * * * * *
