inner web^ which the corresponding bars in U. albigularis do 

 not reach. 



In U. jardinei the flank-feathers, axillaries, and under 

 wing-coverts, instead of being a pure whiter as in U. albi- 

 gularis, are tinted, though but very faintly, with grey, and 

 many of these feathers also exhibit darker shaft-marks of a 

 hair-like fineness. 



The most striking peculiarity of plumage in U. jardinei is, 

 however, to be found in the tail, which, in addition to a 

 slight whitish tip, is crossed on the upper surface by four, 

 and on the under by five, transverse whitish bands, which are 

 entirely wanting in U. albigularis ; these bands, on the upper 

 surface of the tail, are about 0'4 of an inch in depth, the 

 uppermost band being a decided, though not a pure, white, 

 the lowest whitish brown, and the two that are intermediate 

 jn position being also intermediate in hue ; all the bands are, 

 however, more conspicuously white on the outer than on the 

 central rectrices, and more so on the under than on the 

 upper surface of the tail. I may add that the fifth white 

 bar on the underside of the tail is placed higher up than the 

 four bands which are common to both surfaces. 



It is much to be regretted that the habitat of Urospizias 

 jardinei must, for the present, remain unknown ; but, if I 

 am correct in referring this species to the subgenus Uro- 

 spizias, its home will probably be found somewhere in the 

 great Australasian Oceanic Region, which is the home of its 

 congeners ; and it is hoped that the figure which accompanies 

 this article may assist in the identification of future spe- 

 cimens, should any such come to light.
