42 Mr. W. R. Ogilvie-Grant on Birds 



This handsome bird is new to the British Museum, where 

 only P. montium De Vis from the Owen Stanley range was 

 represented. It is easily recognised from the latter by 

 having the feathers of the occiput white tipped with black 

 instead of white shading into grey, and the back and 

 secondaries olive-green instead of sap-green, and the outer 

 feathers of the sides of the body blue, like the breast, 

 instead of dull golden yellow; there are other minor differ- 

 ences. The diflference in the marking of the black and 

 white occipital plumes is not mentioned in Dr. van Oort's 

 description of his bird from the Hell wig Mountains; this 

 important character, coupled with the differently coloured 

 side-plumes, induces me to regard it as specifically distinct.
