however, in the British Museum a male from the Aroa Kiver 

 (E. Weiske), which agrees entirely with the birds from 

 Arfak, having the upperparts black with scarcely a trace of 

 greyish bloom, and the underparts darker. A close examin- 

 ation of the Arfak male also reveals the fact that it is 

 moultino- and that the new feathers on the back are 

 distinctly greyish. The darker colour o£ the underparts 

 is no doubt individual, and is not of subspecific value. 



Salvadori's type-specimen, now in the Genoa Museum, is 

 not a fully adult bird. This is evident from the description 

 of it given by Sharpe in Gould's ' Birds of New Guinea,' 

 for he mentions that the quills have the inner webs rather 

 browner harred with black, and that the underparts show 

 traces of white bars.

The two female specimens, both in immature plumage, 

 are a valuable addition to the Museum Collection, in which 

 the younger stages, which differ so remarkably from the 

 adult plumage, are poorly represented.
