96 REVIEW OF THE 
67. Rhipidura isura Gould. 
Rhipidura isura Gould, P. Z. S. 1840, p. 174. 
Rhipidura setosa (nec Quoy & Gaim.) Sharpe, Cat. Birds Br. Mus. 
IV, p. 329; (?) Salvad. Orn. Pap. II, p. 61. 
An immature specimen from Australia, received from 
Gould, and an adult specimen from Port Essington, col- 
lected by Cockerell, 
This species is undoubtedly fully entitled to specific 
rank, as it is easily distinguished from fF. setosa by its 
dull earthy brown upper surface, by the white shaft-streaks 
on the much paler and narrower chest-band, and more 
especially by the greater extent of the white color on the 
tail-feathers. Amongst /. setosa the specimens with the 
greatest extent of white on the outermost tail-feathers 
(2 em.) are those from the island of Guebeh, which birds 
have the white tips to the second pair much more strongly 
developed than those from any other locality. In the Au- 
stralian specimens the white tip to the outermost pair is 
still longer, measuring 2,4 cm., and the white on the 
outer web is reaching nearer up to the base than in Z. 
setosa. The white tip to the second pair is not longer 
than in our birds from Guebeh (1,5 cm.), but the third 
pair is, though very narrowly and in much worn tails 
not at all, tipped with white, a peculiarity already stated 
by Gould, whereas in none of our 30 specimens of R. 
setosa the slightest indication of such a tip can be found, 
Our immature specimen represents a very interesting stage 
of plumage, having the upper surface earthy brown, the 
feathers of the back narrowly, the upper tail-coverts very 
broadly tipped with fulvous, wing-coverts and quills earthy 
brown, the median and greater coverts broadly tipped 
with buffy white, thus forming a double bar; tips to 
primary coverts as well as broad edges and tips to the 
secondaries dull white.
