varies considerably, while in many of our specimeus the up-per

 secondaries are broad and conspicuous, but these disappear 

 after a time through abrasion. 



45. Hyphanturuus ocularius (Smith). 



Not common. Observed either singly or in pairs. It 

 commences to build about the middle of November, and the 

 vicinity of water is always chosen. Attempts at concealing 

 the nest are sometimes made by interweaving fragments of 

 the surrounding leaf into the network of fibre. 



Adult ^. Total length (measured in flesh) 6*14 inches. 

 Iris lemon-yellow ; legs and feet slate. 



Adult ? . Total length (measured iu flesh) 6'3 inches. 

 Iris lemon-yellow ; legs and feet slate. 



46. Xanthophilus xanthoptkrus (Finsch & Hartl.). 

 We obtained two immature males on August 8 near the 



Shire river, where Sir John Kirk obtained the type of the 

 species. 



Young. General colour above huffish brown, becoming 

 nearly uniform on the rump and upper tail-coverts ; feathers 

 of mantle and back with dark centres ; piimary- and wing- 

 coverts brown, edged with pale yellow ; quills brown, Avith 

 broad yellow bases on the inner webs, outer edges greenish 

 yellow; tail-feathers greenish brown, edged with olive-yellow; 

 crown of head and nape olive-green, with narrow dusky 

 centres ; cheeks, sides of head, and throat pale yellow, re- 

 mainder of underparts white, washed with pale huffish brown, 

 more distinct on the breast and flanks ; under wing-coverts 

 yellow ; upper mandible black, the lower horn-colour ; iris

In the immature bird the quills aud tail-feathers appear to
