ings of dark brown, the lower breast barred with rufous brown, the 

 bars becoming wider apart on the abdomen and under tail-coverts, 

 and more distinctly rufous on the thighs ; quills brown, numerously- 

 barred with darker brown on the inner webs, becoming obsolete on 

 the bases of the latter, which are pale rufous underneath ; tail brown, 

 crossed with about eighteen bars of darker brown, the under surface 

 lighter and ashy white in colour. Total length 18-5 inches, cul- 

 men 1-15, wing 10-4, tail 8-5, tarsus 2-7. 



The young bird described has been considered to belong to A. 

 torquatus by Mr. Wallace ; but its fades certainly refers it to a 

 species allied to A. approxlmans, as does also the sequence of change 

 in its progress towards maturity, of which evidences are beginning 

 to appear in the Bouru specimen. I think that there can be little 

 doubt of its being the young of A. wallacii.
