The Turnicidæ are small Quail-like birds, supposed to have remote affinities with the American Tinamous, and with sufficient distinctive peculiarities to constitute a separate family. They range over the Old World, from Spain all through Africa and Madagascar, and over the whole Oriental region to Formosa, and then north again to Pekin, as well as south-eastward to Australia and Tasmania. The genus Turnix (23 sp.), has the range of the family; Ortyxelos (1 sp.), inhabits Senegal; but the latter genus may not belong to this family.

The Megapodiidæ, or Mound-makers and Brush-turkeys, are generally dull-coloured birds of remarkable habits and economy, which have no near allies, but are supposed to have a remote affinity with the South American Curassows. They are highly characteristic of the Australian region, extending into almost every part of it except New Zealand and the remotest Pacific islands, and only sending two species beyond its limits,—a Megapodius in the Philippine Islands and North-west Borneo, and another in the Nicobar Islands, separated by about 1,800 miles from its nearest ally in Lombok. The Philippine species offers little difficulty, for these birds are found on the smallest islands and sand-banks, and can evidently pass over a few miles of sea with ease; but the Nicobar bird is a very different case, because none of the numerous intervening islands offer a single example of the family. Instead of being a well-marked and clearly differentiated form, as we should expect to find it if its remote and isolated habitat were due to natural causes, it so nearly resembles some of the closely-allied species of the Moluccas and New Guinea, that, had it been found with them, it would hardly have been thought specifically extinct. I therefore believe that it is probably an introduction by the Malays, and that, owing to the absence of enemies and general suitability of conditions, it has thriven in the islands and has become slightly differentiated in colour from the parent stock. The following is the distribution of the genera at present known:—

Talegallus (2 sp.), New Guinea and East Australia; Megacephalon (1 sp.), East Celebes; Lipoa (1 sp.), South Australia; Megapodius (16 sp.), Philippine Islands and Celebes, to Timor, North Australia, New Caledonia, the Marian and Samoa Islands, and probably every intervening island,—also a species (doubtfully indigenous) in the Nicobar Islands.
