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.
