The Guaraünas are birds which have somewhat the appearance of Herons, but which are usually classed with the Rails. They are now, however, considered to form a distinct family. The only genus, Aramus (2 sp.), inhabits the Neotropical region, from Mexico and Cuba to Central Brazil.

The remarkable and beautiful birds called Trumpeters, are confined to the various parts of the Amazon valley; and it is an interesting fact, that the range of each species appears to be bounded by some of the great rivers. Thus, Psophia crepitans inhabits the interior of Guiana as far as the south bank of the Rio Negro; on the opposite or north bank of the Rio Negro Psophia ochroptera is found; beyond the next great rivers, Japura and Iça, Psophia napensis occurs; on the south bank of the Amazon, west of the Madeira, we have the beautiful Psophia leucoptera; east of the Madeira this is replaced by Psophia viridis, while near Pará, beyond the Tapajoz, Xingu and Tocantins, there is another species, Psophia obscura. Other species may exist in the intervening river districts; but we have here, apparently, a case of a number of well-marked species of birds capable of flight, yet with their range in certain directions accurately defined by great rivers.

The Eurypygidæ, or Sun-Bitterns, are small heron-like birds with beautifully-coloured wings, which frequent the muddy and wooded river-banks of tropical America. The only genus, Eurypyga (2 sp.), ranges from Central America to Brazil.
