Birds of Fernando Po. 397 



The fact that tlicsc two female specimens wore obtained 

 in the same locality within a day of each other, and most 

 probably from the same flock, makes it difficult to suppose 

 that they are of different species. 



This Ground-Pigeon is very shy and keeps much to the 

 thick undergrowth in small flocks.
