HORN EXPEDITION—AVES. 
Judging from the above specimens, it may be presumed that very old birds 
have all but the two centre tail-feathers pure white. 
This species, although cpiite distinct, differs only from R. albiscapa in having 
one or two of the outermost tail-feathers on either side pure white, and the 
remainder, with the exception of the two centre tail-feathers, white, narrowly 
edged with blackish-brown on the basal half of their outer webs. 
[In the mulga scrub on Levi Range one of these pretty birds attracted 
attention. In note and habit of ffuttering from branch to branch it closely 
resendjled Rhipidura albiscapa, but its beautiful, fan-like tail, with four snow- 
white feathers on each side of a dark centre, rendered a closer examination 
necessary. Others were also shot at Peterniann and Adminga Creeks.]

[These birds were met with wherever scrub of any description afforded them 
shelter from the numerous Hawks which, no doubt, find the gay plumage of the 
male bird a conspicuous mailt for their keen eyes. They were either single birds 
or in pairs, and are very silent in habit.]
