hopping awkwardly over the ground picking up the fallen seeds. At hlell’s Gate 
a flock of over fifty wei’e on the ground at one time, whilst a few sentinels uttered 
their note of warning from the trees close by. They breed in the spouts of the 
eucalypts along the Finke, Todd, Hale and Palmer Rivers, and the young birds 
are often eaten by the blackfellows.]

as they clustered on a dry branch.] 
The genus Polytelis, in which the next species has hitherto been included, was 
estaldished by Wagler (who separated it from the genus Falceornis of Vigors) in 
1832 in his “ Monographia Psittacorum,” p. 489, for the reception of F. barrabandi,
