the lores and upper portion of the ear-coverts are dusky-black, the latter minutely 
spotted with white, and the white eye-ljrow may be distinctly seen. 
[These birds were shot in mallee scrub near Stevenson’s Creek.]

One adult male and female, one immature male and female, Petermann 
Creek. The latter have du.sky centres and fringes to the feathers of the inter- 
sca 2 iular I'egion, and cons 2 :)icuous dark shaft-lines on the lower back. 
[In the eucaly 2 Dts along Petermann Creek these handsome little birds were 
numerous. Their soft notes are easily recogni.sed and distinguish them from other 
species. Whilst P. ornatus and P. ajjinis give forth a treble note which has 
secured for them the name of “ Pick-it-u2) ” from our Qountry boys, P. rubricatus 
simply gives a double note, the second exactly resembling the hrst. They are 
occasionally found in mallee and mulga scrub, but the eucalypts are their 
favourite haunts. They coniine themselves to the to 2 )S of the trees, and were never 
seen on the ground. As several birds were exploring holes in the hollow branches, 
it is highly 2 ^>'ohable they 2R'efeP nesting in such places to tunnelling in the 
ground like P. punctatus. The sexes arc alike in plumage, but the immature birds 
are not so bright as the old ones.]

One adult male and female, Heavitree Ga 2 i. The former is similar in 25lumage 
to examples from the western district of New South AVales, and which are 
slightly smaller than specimens obtained in heavily-timbered mountain ranges or 
near the coast ; but the black dorsal band in the female, and also in an adult male 
from Owen Springs, is very much narrower than in any other birds I have 
examined of this S23ecies. Both are fully adult, but many of the black feathers on 
the back of the male are ti2J23ed with white, and those of the female with greyish-
