C. fuajJiaga. Most of these forms are so alike, and their o-eo- 

 graphical distribution is so wide and curious, that very few races 

 can be kept separate. I cannot allow specific or even subspecific 

 rank to either the birds from AustraHa or those from Mauritius but 

 may recognize as a subspecies the dark-rumped bird from' the 

 Andamans, i e. C. inexpectata of Hume, and the paler bird from 

 Mergui, so that we have two forms which are somewhat differen- 

 tiated in their respective habitats. It may seem feasible to allow 

 subspecific rank to the Pacific specimens on account of their generallv 

 darker upper surface; but larger series show that this character is
