 Adult Male — General colour of plumage blacky glossed with 

 purplish and steel-blue, and finely mottled with white ; lower 

 back fiery bronzy-gold, shading into bronzy-red on the rump ; 

 sides finely mottled with white ; tail pale rufous-buff. Total 

 length, 20 inches; wing, 9*5 ; tail, 6*4; tarsus, 3. 



Adult Female. — Plumage entirely black, glossed with purplish 

 or steel-blue. Total length, 18-5 inches ; wing, 8-4 ; tail, 5-4 ; 

 tarsus, 2-8. 



' Rauge — Southern part of the Malay Peninsula and Sumatra. 

 Has been recorded from Java, but probably in error. 



HalDits — Practically nothing has been recorded about the 

 habits of this bird, and the only examples obtained are those 

 snared by natives. It is only known that the Malayan Crest- 

 less Fire-Back frequents the dense damp forests, and we may 

 fairly assume that its habits are much like those of its ally the 

 Crested Fire-Back, described below. 



* The female of A. inomalus is still unknown.
