The BRIDLED BEE-EATER (_Coccolarynx frenatus_), a species inhabiting the forests near the Blue River, possesses a delicate, thin beak, a moderate-sized, straight tail, and most glowing and variegated plumage. The upper portions of the body are green, the under side is reddish brown; the brow green and blue intermixed; the throat scarlet; the belly, rump, and under tail-covers are bright blue; the black cheek-stripe, which passes across the eye, is bordered with blue; the eye is bright red, and the beak and foot black. The length of the body is eight inches; the wing measures three inches and one-third, and the tail three inches and a half. This elegant little bird is very numerous in Central Africa, where it is usually met with in large parties, which rarely fly to any distance above the tree-tops in pursuit of their insect fare, and seize their prey more after the manner of the Flycatchers than of the Swallows. According to our own observations, these birds appear to remain for months together in the vicinity of their settlements of nests. During the Christmas of 1850, whilst anchored in the Blue River, we found at least sixty of the holes employed as nests by this species excavated in a clay bank on the shore; the whole number occupying a space not exceeding thirty-six square feet, and so close together that the entrances were not more than five or six inches apart. The passages to the nest-holes were about an inch and a half in diameter, and from three to four feet deep, terminating in a chamber from six to eight inches long, by four or six broad, and two and a half to three inches high. We found neither building materials nor eggs in these holes, although the birds were constantly creeping in and out of them. THE SWALLOW BEE-EATER. The SWALLOW BEE-EATER (_Melittophagus hirundinaceus_), another species inhabiting Africa, differs from the birds above described in the formation of its very deeply forked tail. The mantle is glossy yellowish green, the lower part of the back and tail being of a somewhat deeper shade; the under side is light green; the throat saffron yellow, and divided from the breast by a line of rich ultramarine blue; the vent and a line that passes from the nostrils over the eyes are deep blue; the cheek-stripes are black. The body of this species is eight inches and a quarter long; the wing measures three inches and a half, and the tail four inches and one-sixth. Le Vaillant, who discovered this beautiful bird in Southern Africa, tells us that it lives in pairs till after the period of incubation, when old and young associate in small parties, previous to the season of migration; they then assemble in very large flocks. The nest resembles those of other Bee-eaters. The eggs, six or seven in number, have a blueish-white shell. We also learn from Vaillant that this brilliant creature exhales a very agreeable odour, resembling the perfume of a fragrant flower. THE AUSTRALIAN BEE-EATER.
