136 Mr. R. Hall on Birds 
The tendency of the subterminal black band in this 
species is to be as strongly marked on the outer web as 
on the inner; while in A. pusilla, which bears a strong like- 
ness to it, the tendency is for the inner web alone to be 
banded with black. The inner web of each rectrix is 
more or less tipped with white in the males and females of 
this form. 
Along the partially cleared river-tracts, due to the work of 
saw-millers, this little bird is always obtainable during the 
aforesaid months of the year. From one nest I extracted 
a young Cuckoo [Cuculus flabelliformis), almost fledged, and 
a {pathetic lamentation was set up by the foster-parents. 
Taking the nest from among the Melaleuca branches, I placed 
it at the base of the tree, when the little Tits approached very 
closely and became quite excited. A and B indicate these 
birds, while the " parasite " is elsewhere referred to.

Two adult skins obtained on September 27th and 28thj 
twenty miles apart (Denmark and Tor Bay), have a deeper 
coloured plumage than my eastern skins, and also a portion of 
the barb of each feather of the occiput striped with black. 
A comparison with more specimens is necessary to decide the 
value of the observations. At Katanning (5.10.99) I observed 
a rather peculiar nest. It had two entrances to the lower 
chamber near each other. The unroofed apartment above was 
higher than usual. In a proteaceous tree close by were the 
remains of last yearns nest built upon the same principle. I 
secured fresh eggs near Albany on Sept. 29th, at Katanning 
on Oct. 5th, and at Geraldton on Oct. 28th.
