 species form a natural group which cannot be consistently subdivided, unless P. calo- 

 rhynchus be also made the type of a separate genus. Within the limits of PhcenicopJiaes 

 I am also inclined to include Melius diardi, Less., and also Cuculus sumatranus, "Rfifflp«

 Australian regions are necessary to enable us to establish the identity of the Celebean 

 member of the genus.
