shaped shaft streaks ; the entire back of the neck, back, and 

 shoulders, the same, "with larger spots; the rump, brownish-ash, 

 tinged strongly with rust-colour. All the under parts, from 

 the pure white chin and throat, are pearl white, tinged with 

 yellow about the sides and vent ; the under tail-coverts are 

 reddish-yellow, with white tips to the feathers. The quill- 

 feathers are dusky black, with a white tip to each, largest 

 on the three last feathers, where they form a triangular 

 spot ; from the fourth to the fifteenth quill-feather runs a 

 yellowish-white band through the middle of each, thus 

 forming a bar on the closed wings, which bar has marked 

 angles, and seems closed in with black, as it is only when 

 the wings are extended that the white band across them is 

 perfect and straight. The larger wing-coverts are dusky, with 

 triangular white spots at the tips of the feathers and outer 

 webs, and these white tips are yellowish on their upper edges; 

 the secondary wing-coverts and tertials are dusky, with white 

 elongated or pointed spots ; the tail-feathers are brownish- 

 ash, yellowish towards the outer edges, and dusky along the 

 pale brownish-yellow shafts. There is no apparent difference 

 between the male and female in the feathering, or at least 

 none that can be detected unless they are closely compared 

 together. 



The egg figured 189 is that of the Tree Creeper.
