This species resembles P. hosei very closely, the chief and really 

 only diflference is that the head is mostly black instead of white, and 

 the under parts cream color. Its proper rank will probably be that of 

 a subspecies, but as no intermediate examples of the forms have been 

 obtained, it must for the present be regarded as an independent species. 

 Mr. Hose says both species are found on Mt. Dulit and also on Mt. 

 Batu Song, but P. everetti has not been found in the low country.
