622. Attagen Ariel, _Gould_ Vol. VII. Pl. 72. 623. Attagen Aquila? Genus PHAËTON, _Linn._ The beautiful species of this form which graces the fauna of Australia, ranges over the greater part of the Pacific Ocean, and among other places retires to Norfolk Island and Raine’s Islet for the purpose of breeding. 624. Phaëton phœnicurus Vol. VII. Pl. 73. Genus PELECANUS, _Linn._ The members of this genus are very widely dispersed, since every great country has one or more species assigned to it. That inhabiting Australia is as fine and as beautifully marked as any other member of the group. 625. Pelecanus conspicillatus, _Temm._ Vol. VII. Pl. 74. Genus PLOTUS, _Linn._ Asia, Africa, America and Australia are each tenanted by a species of this genus, the members of which, although few in number, are not well understood nor are their specific differences easily decyphered. 626. Plotus Novæ-Hollandiæ, _Gould_ Vol. VII. Pl. 75. Genus SULA, _Briss._ Four fine species of this genus appertain to the Australian fauna, since they not only frequent the seas adjacent to the shores of that country, but all of them resort to its rocks and islands for the purpose of breeding. The genus comprises several other species which inhabit the sea coasts of nearly every part of the globe. 627. Sula Australis, _Gould_ Vol. VII. Pl. 76. Inhabits the southern coast of Australia and Van Diemen’s Land, and is a beautiful representative of the _Sula Bassana_ and _S. melanura_ of Europe. 628. Sula personata, _Gould_ Vol. VII. Pl. 77. Common on the east coast. 629. Sula fusca, _Briss._ Vol. VII. Pl. 78.
