Genus NYCTICORAX, _Steph._ Europe, Africa and America are all inhabited by Night Herons; consequently it is one of the most widely-distributed sections of the family. The single Australian species of this well-defined genus is rendered conspicuously different from all other known species by the cinnamon colour of its back. 519. Nycticorax Caledonicus Vol. VI. Pl. 63. “Shot at Cape York and Port Essington, in which latter place it is rather abundant. _Yangko_ of the Cape York aborigines, _Alăwool_ of the Port Essington natives.”—_J. M’Gillivray._ Genus BOTAURUS, _Steph._ 520. Botaurus Australis, _Gould_ Vol. VI. Pl. 64. The Australian Bittern is very similar to the European, _B. stellaris_. Genus ARDETTA, _G. R. Gray_. The members of this genus of Mangrove Bitterns usually frequent the extensive belts of mangroves and low dells covered with reed-beds and dense herbage. Africa and America are each inhabited by birds of this form, one species of which is also found in Europe, several in India and the adjacent islands, and three in Australia, viz.— 521. Ardetta flavicollis Vol. VI. Pl. 65. This species is said to inhabit Java and India, and although I have figured it under the name assigned to the Indian and Javanese bird, I am still inclined to believe that it is distinct. 522. Ardetta macrorhyncha, _Gould_ Vol. VI. Pl. 66. 523. Ardetta stagnatilis, _Gould_ Vol. VI. Pl. 67. 524. Ardetta pusilla Vol. VI. Pl. 68. This species, with the little Bittern of the British Islands and several others inhabiting Africa and America, would admit of being separated into a distinct genus. Family RALLIDÆ, _Leach_. Of this family no less than sixteen species inhabit Australia, and are comprised in the following genera, viz. _Porphyrio_, _Fulica_, _Gallinula_, _Rallus_ and _Porzana_, all of which are European forms; and _Parra_, _Eulabeornis_ and _Tribonyx_: of the latter, the first is common to India and the Indian Islands, and the other two are confined, so far as we know, to Australia. Genus PORPHYRIO, _Briss._ 525. Porphyrio melanotus, _Temm._ Vol. VI. Pl. 69. 526. Porphyrio bellus, _Gould_ Vol. VI. Pl. 70.
