The two species of this genus, all that are at present known, are confined to the south-eastern portions of Australia and Van Diemen’s Land.

Genus Petroïca, Swains.

The birds I have retained in this genus might with propriety be divided by separating the pied Robins from the red-breasted species. The dusky Robin of Van Diemen’s Land and the white eyebrowed Robin of the north-east coast of Australia would also constitute another group of equal value with Erythrodryas, Drymodes and Eöpsaltria.

The red-breasted Petroïcæ are confined to the south-eastern portions of Australia, Van Diemen’s Land and Norfolk Island; but I believe that the range of the pied birds extends to New Guinea.

Each of the sections I have indicated present some difference in their nidification and in the colouring of their eggs, which tends to confirm the propriety of the view I have taken of the subject.
