Tue genus Mierwca was instituted by me in 1840 for the reception of the present bird and the J Sascinans of Latham, also an Australian species. Since that time only two or three species have been discovered in the Papuan Islands and North-eastern Australia; so that in Micreca we have a thoroughly Australian genus of Flycatchers, representing the true Flycatchers of Europe and Asia. It may be noticed that the two best-known Australian species, Micraca fascinans and M. assimilis, in their sober brown coloration are not unlike the Common Flycatcher (Butalis grisola) of England. The present species very closely resembles JZ. fascinans of New South Wales, of which it is the represen- tative in Western Australia ; but it is smaller, and, instead of having the outer tail-feathers pure white, has only the tip of the inner web and the outer edge of the external tail-feather white. The species is described in full by Mr. Sharpe, whose words I here transcribe :-— “
