When I characterized this species in the ‘Proceedings of the Zoological Society of London,’ I had only seen a single example; I have since received a second, proving the correctness of my view of its being quite distinct from the H. pyrrhopygia, a fact disputed by Mr. Strickland, who had stated it to be his opinion that my figures were referable to one and the same species, but who upon an examination of the specimens themselves acknowledged he was in error.

Genus Cysticola, Less.

However numerous birds of this form may be in Europe, Africa, Asia and the Indian Islands, Australia outvies them all in the number of species that frequent its grassy plains. With the exception of Van Diemen’s Land, every colony is inhabited by one or more species performing there precisely similar offices to those executed by the remaining species in the other parts of the world.
