404. Enphema Bourkil  . ; , . ; . Vol. V. Pl. 48. 
Captain Sturt found this species in abundance at the Depdt in Central Australia. 
Genus Mexopsrrracus, Gould. 
Generic characters. 
Bill moderate ; culmen arched ; tomia descending at the base, then ascending and curving dewnwards to the tip; 
nostrils basal, lateral, open, and seated in a broad swollen cere ; wings rather long, pointed, first primary very long, 
the second the longest ; tai/ long and much graduated ; farsi moderate and covered with minute scales ; (oes slender, 
the outer toe much longer than the inner one, 
The only known species of this form is strictly gregarious, assembles in vast flocks, and is admirably adapted 
for plains and downs covered with grasses, wpon the seeds of which it entirely subsists. 
405. Melopsittacus undulatus . , ; ; ‘ , ; Vol. V. Pl. 44. 
In all probability this bird is universally dispersed over the whole of the interior of Australia, since indepen- 
dently of its previously known range from Swan River on the west to New South Wales on the east, Mr. Gilbert 
observed it in every part of the country between Moreton Bay and the Gulf of Carpentaria. 
Genus Nympuicus, Vag. 
As of Melapsittacus, there is only one species known of this genus. It is strictly Australian, and will doubtless 
hereafter be found to be universally distributed over that vast country ; it is equally adapted for the plains, and the 
two birds are frequently found associated. 
406. Nymplhicus Nove-Hollandie . 4 ' . , i , : : ; ' ; Vol. V. Pl. 45. 
There are two distinct varieties of this species, one having a much darker colouring than the other. 
Genus Przororus, LZ. 
Of this terrestrial form but one species is known, which is very generally distributed over the temperate 
portions of Australia, the islands in Bass’s Straits and Van Diemen’s Land. The eggs are laid on the bare ground. 
407, Pezoporus formosus . ‘ . : ‘ ; ; , ; Vol. V. PL. 46. 
Genus LarxnAmus, Less. 
Of this form only a single species is known to exist in Australia, and that species had been assigned to a 
different genus by almost every recent writer on ornithology, Messrs. Vigors and Horsfield placing it im their 
venus Nanodes, Wagler in his genus Euphema, &c.; subsequently M. Lesson made it the type of his genus Lathamus, 
wiving it at the same time the specific appellation of rubrifrons, which must of course give place to that of discolor, 
long before applied to it by Latham. 
Having had ample opportunities of observing this bird in a state of nature, I concur in the propriety of M. 
Lesson’s views in separating it into a distinct genus, at the same time I must remark that in its habits, nidification, 
food and whole economy, it is most closely allied to the Trichoglossi or honey-eating Parrakeets, and in no degree 
related to the Kupheme.
