The type o£ this species, which is in the British Museum, 

 was obtained by A. Goldie in the Astrolabe Mountains ; it 

 agrees in every respect with the specimens procured by the 

 Wollaston Expedition on the Utakwa R-iver. The amount 

 o£ black on the forehead varies individually: in some examples 

 it does not extend much beyond the anterior border of the 

 eye, as in the type-specimen from the Astrolabe Mountains 

 and the male (a) from the Utakwa River ; in other specimens 

 from South-east New Guinea the black is much more exten- 

 sive, reaching considerably beyond the posterior margin of 

 the eye. Again, in some examples, both male and female, the 

 black on the crown terminates posteriorly in numerous black 

 spots which, in one specimen, extend almost to the occiput. 

 This variation is probably due to age, the spots denoting the 

 younger birds. 



The male (a) has the rufous-chestnut of the breast and 

 underparts darker than in the three females (b-d). 



1 male, wing 85*5 mm. ; 3 females, wing 80, 83, 83 mm.

Birds from the Mimika and Setakwa Rivers are referred 

 with some doubt to the Aru Island form. The males 

 of our series and M. c. aruensis appear to be indis- 

 tinguishable from one another, but the female from the
