 D. javanica, of the latter area only, has them chestnut above and 

 fulvous white below ; D. arcuata, ranging from the Malay Archi- 

 pelago to Fiji, has the breast chestnut barred with black ; D. 

 eytoni, of Australia, which has strayed to New Zealand, has it

 of other birds, contains from six to twelve white eggs.
