An extremely distinct species, nearest H. philippinensis, 

 Walden, from Luzon and Dinagat, and more distantly allied to 

 H. griseiceps (Gray) from the Papuan Islands. In both these 

 species, however, the head is differently coloured from the 

 rest of the upper parts, that of the former being dark brown 

 slightly washed with olive, while in the latter it is gi'eyish 

 brown. In the new species the head is dull olive-green like 

 the mantle. There are also many other marked differences. 



Male and female adult. Top of the head and mantle dull 

 olive-green, shading into bright olive-yellow on the rump 

 and upper tail-coverts ; sides of the head and ear-coverts 

 olive-grey ; chin, throat, and chest greyish white, darker 

 and slightly washed with olive on the sides ; belly white ; 

 vent and under tail-coverts washed with yellow. Quills 

 brownish black, margined with olive-yellow on the outer web. 

 Tail-feathers olive-yellow, brightest on the outer web, and 

 duller towards the extremities.
