This remarkable little bird was first discovered on tlie 

 Moonda River by Du Chaillu, and the type is preserved in 

 the Philadelphia Museum. It is evidently a very rare 

 species, and the example obtained by Alexander is the only 

 specimen from West Africa in the British Museum. 



Three allied species have been described from various 

 districts in East Africa which, when more material is 

 available, will probably turn out to be subspecies of P. in- 

 signis, which is the oldest name. 



P. insignis Cassin, is the only form described from West 

 Africa up to the present time. Mr. W. R. Ogilvie-Grant 

 has kindly permitted me to look through a fine collection of 

 birds (not yet the property of the British Museum) recently 

 obtained by Mr. G. L. Bates from southern Cameroon. In 

 this collection I have found another example of P. insignis^ 

 which Mr. Bates procured on the River Ja. 



Thanks to Mr. Alexander and Mr. Bates, there is now in 

 the British Museum a very fine working collection from 

 Cameroon.
