One of our specimens of this species was brought by Mr. Brown 
from the banks of the Derwent, where he obtained it in 1804. 
It appears to be the bird from which the late M. Kuhl took the 
description of his Psittacus australis (p. 48. no. 74). He refers to 
a specimen in the Linnean Society's collection, and there is no 
other bird in that collection which accords with his description. 
We do not observe any material difference between our speci- 
men and the Psitt. discolor of Dr. Latham. The front is some- 
what more yellow than is usual in the species ; and when the bird 
is compared with M. Le Vaillant's figure, in which the front is 
pure scarlet, a slight difference appears, which may have given 
rise to M. Kuhl's separating the two birds. In most of the 
birds, however, which are considered to belong to M. Le Vail- 
lant’s species Perruche Banks, and Dr. Latham's P. discolor, a 
greater or less proportion of this yellow marking is discernible. 
M. Le Vaillants figure appears to us too highly coloured. 
Mr. Swainson's is an excellent representation of the bird. There 
join Paleornis by the osculant species Pal. Papuensis; and fifthly, the species of 
various countries, known by the general title of Perruches proprement dits, including 
Brotogeris, V., united to Lorius of the last subdivision by Psitt. fringillaceus, Lath., 
and leading round again to the first subdivision of Parrakeet Maccaws by some Ame- 
rican species, whose bills gradually shortening, and becoming stronger, indicate an 
approaching affinity to that group.
