of blackish-brown ; the band through the wing ricli buff, instead of pale greyish- 
buff ; the ear-coverts in the male dark greyish-black streaked with white, instead 
of uniform greyish-brown, and the orbital region and superciliary stripe pure 
white, instead of rusty-red. The female also has the white superciliai’y stripe, 
but bordered above by a narrower one of rusty-red, and in both sexes the under 
surface is more broadly and distinctly streaked with pure white, instead of dull 
white. 
Upon examining the reference collection in the Australian Museum, I find 
there is a male and female of this species obtained in July, 1883, by the late Mr. 
Kenric Harold Bennett on Moolah Statiim, in the central province of New South 
Wales. The specimens procured by IMr. Keartland at Illara Creek and Bagot’s 
Creek are alike in plumage, and are marked respectively male and female; but 
the examples obtained by Mr. Bennett at Moolah, and shot together while nesting, 
vary as described above. There is also another specimen in the refei’ence collection 
from Queensland marked a female, which is precisely similar to the one from 
Moolah. The latter specimens are marked male and female, “ iris brown, legs 
and feet black.” 
An egg of C. supe7'ciliosa, received by Mr. Keartland from Central Australia 
and taken by IVIr. Cowle from the hollow spout of a tree, is a rounded oval in form 
and closely resembles a small egg of C. scandois; it is of a pale I’eddish-white 
ground colour, thickly spotted and dotted all over with rich reddisli-brown 
markings, which are larger and become confluent on the thicker end ; length 
0-73 inch x 0'G7 inch. 
[Like all members of this genus, we found this Tree-creeper busily at work on 
the trunks of all kinds of trees. They always flew to the base of the trunk, and 
working upwards in a spiral manner, soon reached the top, when they would 
immediately fly to the base of the next tree. The Sittella seems to prefer working 
head downwai’ds, but the Tree-creeper is seldom if ever seen in that position.]
