As in _Euphema_, but the _cere_, in which the nostrils are placed, more swollen or developed; _wings_ rather short and the _tail_ much lengthened; the lateral feathers short and not so regularly graduated; _feet_ more adapted for terrestrial progression. All the members of this genus are confined to Australia, and hold an intermediate station between the _Platycerci_ on the one hand and the _Euphemæ_ on the other. They pass much of their time on the ground, where the principal part of their food is procured; inhabit the interior rather than the country near the coast, and are adapted for the open plains, where they often assemble in vast flocks. I have figured four species, and I have seen a drawing in the possession of Mr. Brown, made by Ferdinand Bauer from a bird said to have been found near the Gulf of Carpentaria, which will probably form a fifth. 394. Psephotus hæmatogaster, _Gould_ Vol. V. Pl. 33. This species differs from all the other members of the genus, as well as from those of the allied genera, in the pointed form of the tips of its primaries. If they be not local varieties of each other, there are two birds confounded under this name, one having yellow and the other scarlet under tail-coverts; it will be necessary, however, to see other examples before we can decide whether they are or are not distinct. Captain Sturt brought specimens with yellow under tail-coverts from the Depôt in the interior of South Australia. 395. Psephotus pulcherrimus, _Gould_ Vol. V. Pl. 34. 396.
