The specific term of pyrrhonota having been given to a bird of this group by Vieillot, prior to the publication of the List of Australian Birds by Messrs. Vigors and Horsfield in the Linnean Transactions, as quoted above, I have been necessitated to furnish this species with a new appellation, and have selected that of arborea as indicative of its habits; for in every part of Australia that I have visited, it invariably selects the holes of trees for the purpose of nidification.

It is strictly a summer visitant to Van Diemen’s Land and all the southern portions of Australia, arriving in August and retiring northwards as autumn approaches.
