This rapid-winged night bird is widely distributed over South-eastern Australia, if not over every part of the Continent. I have often watched the motions of this light and airy bird round a pond of water close to which I have been lying, with the full bright moon above me, and been amazed at its rapid evolutions; and admired the wisdom of that Providence which had so adapted this little animal for the part it was to act on the great stage of the universe. So light, that it had no difficulty in maintaining a prolonged flight, with its noiseless wing, making its sweeps to greater or lesser distances, and seeming never to require rest. The habit of this Goat-sucker is to lie under any tree or brush during the day, from which it issues in great alarm on being roused.

18. CHELIDON ARIEL, GOULD.

The brown-headed Swallow, a common bird in the interior during the summer. Gregarious, and building clay nests, like bottles stuck against a tree, in rows one above the other. Instinct guides these little birds to select a tree that slopes and is concave, in which the nests will be protected from rain or storms. A white-headed swallow was also frequently seen, but it was always under circumstances that prevented our procuring a specimen.

19. MEROPS ORNATUS, LATH.--Australian Bee-eater.

This beautiful little bird, with its varied plumage, is migratory, and visits the southern parts of the continent during summer, when its locality is near any river, or chain of ponds, although it is also found in other places. I first shot this pretty bird on the banks of the Macquarie in 1828, where it was in considerable numbers. It visits Adelaide, and we saw it in the interior almost to our extreme north.

20. HALCYON SANCTUS, VIG. AND HORSF.--Sacred Halcyon.

This ill-proportioned bird in shape and general appearance is like the Kingfisher. Instead however of living on fish, he contents himself with lizards, beetles, grasshoppers, etc., and amongst these he makes a great havoc. The range of this bird did not extend beyond the lat. of the Depot.

21. HALCYON PYRRHOPYGIA, GOULD.--Red-backed Halcyon.

Similar in shape and figure to the last, but differing in plumage and in size, having dull red feathers over the rump, the blue being also of a duller shade. It ranges far north.

22. ARTAMUS SORDIDUS.--Wood Swallow.
