Pardalotus nropygialis, Gould, Birds of Australia, fol., vol. ii. pi. 41. 



Per this very beautiful Diamond-bird, and several other in- 

 teresting species from the north-west coast of Australia, I am 

 indebted to the kindness of the late Benjamin Bynoe, Esq., 

 Surgeon of Her Majesty's Surveying Ship the Beagle; to 

 Captain Wickham and the other officers of which vessel my 

 thanks are also due for their polite attention to my wishes, 

 and the promise of communicating to me any novelties they 

 might procure during their survey of the north-west coast. 



The Yellow-rumped Diamond-bird is easily distinguished 

 from every other species of the group with which I am ac- 

 quainted by the bright yellow colouring of the lower part of 

 the back, by the rich spot of orange before the eye, by having 

 a shorter wing, and by being more diminutive in size than 

 any of the others, with the exception of Pardalotus ^unctatus. 



I am unable to give any account of its habits and manners ; 

 but in these respects it doubtless closely assimilates to the 

 other members of its group. 



Crown of the head, stripe before and behind the eye black ; 

 lores rich orange ; a mark from above the eye to the occiput, 

 chest, and centre of the abdomen white ; throat and cheeks 

 delicate crocus-yellow ; rump and upper tail-coverts sulphur- 

 yellow ; back of the neck and back olive-grey ; wings black, 

 the external webs of the second and five following primaries 

 white at the base ; tips of the spurious wing scarlet ; tail 

 black ; the three outer feathers tipped with white, the white 

 spreading largely over the inner web of the outer feathers -, 

 bill black ; feet lead-colour. 



The sexes do not seem to differ in size or in the colour of 

 their plumage.
