occasion. For the present it is sufficient to state that the 

 Sumatran bird appears to be readily separable from all Malay 

 Feninsnla birds by its much darker colour throughout especial- 

 ly on the sides of the head and foreneek and by the muel 

 duller crown. In the Bornean bird the head is dark ^rey 

 throughout. Such evidence as is on record goes to show that 

 the species does not occur at all in Java, and that the type 

 which is not apparently in existence is just as likely to have 

 come from AEalacea as from Singapore.
