Adult. Differs from G. melanolophus in its deep vinous-chestnut 

 head, which has a little shade of blackish on the forehead only ; the 

 mantle is browner, and the upper surface generally never seems to 

 be free from dusky vermiculations ; the axillaries are black and 

 rufous instead of black and white, and there are no white tips to 

 the outer primaries. Total length IS inches, culmen 1-55, wing 

 10'2, tail 3' 7, tarsus 2"o. 



Young. Differs from the adult in being browner and more uniform 

 o\\ the upper mantle and back, but with the wings much freckled 

 with rufous buff; crown of head dusky blackish, inclining to dark 

 vinous on the neck. The young bird differs from the young of 

 G. nidanoloplius by the rufous tips to the primaries. 



The description of the young bird is taken from a bird pro- 

 cured by ilr. Uinger at Nagasaki, which still retains some of the 

 nestling down on the head. Full-grown birds, exactly similar in 

 plumage, are in the collection from Luzon and Ayala in Mindanao: 

 •" bill green, culmen black ; legs and feet green ; iris yellow " 

 (£". L. Mosdey). 



Hah. Japan. Occurring as a winter visitor in Formosa and the 

 Philippines.
