We can detect no differences between Malayan and Suma- 

 tran birds. Old birds have the cap deep black and it is to these 

 that the name Malacopteron ' melanocephalum was applied by 

 Davison. The Bornean form is slightly larger and has a 

 dull, or less marked, cap with the tail and upper tail coverts 

 much richer rufous and has been named Setaria (Alcippe) 

 drier eocapilla by Salvadori.* It is unlikely that this form and 

 8. affinis both occur in Sarawak.
