Inhabits the north coast. I have not figured this species because it only differs from R. rufifrons in being of a smaller size, and in the red colouring at the base of the tail-feathers being more extensive.

Not figured, being similar in colour but much smaller than R. Motacilloïdes; it inhabits Port Essington.
Genus Seïsura, Vig. & Horsf.
The present genus and Rhipidura are mere modifications of each other; a difference of structure, however, exists of sufficient importance to justify their separation, and, as is always the case, a corresponding difference is found in the habits of the species.
The present form is restricted to Australia.
