the present misuse of the term " subspecies.'^ Here we have 

 two perfectly different and easily recognised species repre- 

 senting two distinct types of the same genus, and I consider 

 it most misleading to place the present species as a subspecies 

 of M. fiaviventer. 



Besides M. xantJiogenys, which inhabits the Aru Islands, 

 and ranges from Southern Dutch New Gruinea to South-east 

 New Guinea, there are also found the following closely 

 allied forms : — 



1. M. alhifrons Gray (type in the British Museum), 

 occurring in Waigiu, Misol, and North-west New Guinea. 



2. M. alhifrons novus Roths. & Hartert, inhabiting Northern 

 British New Guinea, from the Kumusi River and Collin g- 

 wood Bay.

As pointed out by Dr. van Oort, the eastern race of this 

 species from the Owen Stanley Range is distinguishable from 

 the typical Arfak form by its somewhat larger size and by 

 the darker colour of the upperparts in the female. 



Subsequently Messrs. Rothschild and Hartert distin- 

 guished the birds from Mount Goliath under the name 

 M. n. saturatus, the females being said to have still darker 

 upperparts ; but I do not think they are really separable 

 from M. n. harterti, as a female specimen from Dorawaida 

 typical of the latter is indistinguishable from the female (c)
