The members of this genus, as now restricted, are found in all the islands of the Indian Archipelago, Australia, and New Zealand. The Australian species, which are four in number, have many habits in common with the Dacelos, and like them dwell among other places on the open plains, far away from water, and consequently must live for considerable periods without a supply of that element.

Captain Sturt found this species at the Depôt, and I have received specimens from the Swan River Settlement; consequently it has a very wide range, but is more an inhabitant of the interior than of the districts near the coast.

Independently of the Cobourg Peninsula, I have received specimens of this bird from Moreton Bay and other parts of the east coast.

Genus Alcyone, Swains.

The Australian members of this genus are so intimately allied that I have only deemed it necessary to figure two species, viz. Alcyone azurea and A. pusilla; the two species not figured are both nearly allied to A. azurea, and may be considered its northern and southern prototypes, since the one to which I have given the name of pulchra inhabits the north coast, and the other, which I have called Diemenensis, inhabits Van Diemen’s Land. The A. azurea inhabits the intermediate or rather the south-eastern portions of the country, but no species of the genus has yet been found in Western Australia. They all frequent the margins of rivers, and live on small fish and insects, and have many habits in common with the members of the genus Alcedo, of which the Kingfisher of Europe, A. Ispida, is the type. Although some species are found in New Guinea and the Indian Islands, Australia is the country in which birds of this form are most abundant.
