patch on the wing larger and more conspicuous. The female has the crown 
dove-colour tinged with leaden-grey and the rump bluish-grey ; no real blue 
in either. The display of these birds is peculiar and utterly unlike that of 
other Parakeets, including Polytelis swainsonii. The male begins by uttering 
various cries, some harsh, some shrill, and also whistles in different keys, at 
times slowly, at times rapidly. If a female shows interest in this performance 
he approaches her with a quick run, his head held high, his neck stretched 
upwards and his plumage kept close and tight, the bird’s elegant form and 
beautiful colouring being thereby exhibited to the best advantage. The 
male then, as a rule, bobs his head up and down a few times and utters a 
low chacking noise very hke that sometimes made by an angry cock Broadtail 
on the approach of a rival. On getting quite close to the female he finishes the 
exhibition by gazing very intently into her face, and every now and then 
rapidly rubbing his beak on the side of the branch nearest to her. The female 
displays to the male in an exactly similar way, though she does not begin by 
whistling and usually waits for him to furnish this vocal prelude. From 
observation of captive birds I am inclined to think the species is not mono- 
gamous, but very ‘ Cuckoo ’ in its conjugal affairs. The female alone 
appears to care for the young, though the male does not molest them when 
they leave the nest.” 
Ohs. In the Austral Av. Rec., Vol. III., pt. 5, p. 128, Dec. 28th, 1917, I 
described ErytJirotriorchis radiatus queenslandicus. This bird is identical with 
the one figured by me in my Birds of Australia, Vol. V., pi. 240, except 
that the white abdomen is lacking, the under-surface being a uniform rufous 
colour.

Through the confusion of publication of Reichenbach’s, Bonaparte’s 
and Cabani’s work the correct generic name for the Spotted-sided Finch 
was left in abeyance. I have now determined that Bonaparte preceded 
Cabanis, so that we arrive at the following conclusions : — 
Stagonopleura Reichenbach, Av. Syst. Nat., pi. lxxv., is based on figures 
of beak, wing, tail and feet, and is accurately indeterminable. This may 
have been published in June 1850, but that is not certain. 
In the Conspectus Gen. Av., Vol. I., p. 456, which was published 
before Feb. 1851, Bonaparte introduced Steganopleura as of “Reichenb.,” 
but marked with a * to indicate this was the first publication. He 
included thereunder hichenowii Vig., annulosa Gould, ruficauda Gould and 
modesta Gould. These are now referred to three different genera, and 
aU of the same time of proposal, but as one was preoccupied it has been
