 Type, Cape York, No. 13,154. 

 Range, Queensland (Cape York). 



In the Emu, Vol. X., p. 339, 1911, Campbell recorded 

 the New Guinea C. mentalis Salvadori and d'Albertis as 

 a Cape York breeding bird". I have now received a 

 series of birds from that locality, and upon comparison 

 with a series from the type-locality I find that the Cape 

 York bird is smaller in every dimension. An immature 

 specimen from Nicura (the type-locality) which is just 

 commencing to take on the adult-plumage, has a wing 

 equalling that of the largest Australian specimen, while 

 its bill is much heavier. The back of the neck in the 

 Australian bird has less white, and the white on, the 

 tail-feathers is less extensive. The bill in the New 

 Guinea bird is longer and heavier, and the tarsi are also 

 longer and stouter. Measurements of largest Australian
