 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 Phcenicophaes 

 I am also inclined to include Melias diardi, Less., and also Cuculus sumatranus, "Rafflp*

The synonymy of the species usually comprised in Cacomantis, S. Miiller, is still so 

 entangled, that a few general remarks on the Plaintive Cuckoos of the Indian and 

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

 member of the genus.
