from the base to the tip ; slightly notched at the apex; rictus beset with a few fine hairs; nostrils basal, oblong,

rather large and defended by an operculum; wings short, round and concave ; first, second and third primaries

A genus comprising two species peculiar to the southern parts of the country, one of which enjoys an

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 Cysticoxia, 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 mhabited by one or more species performing there precisely similar offices to those executed by the

remaining species in the other parts of the world.
