typical P. marmorata from British New Guinea ? Tlie former, 

 when arranged in series, are distinctly, if slightly, darker 

 grey below, but the diflFerence is so slight that I have not 

 thought it desirable to separate them, especially as this 

 character is not supported by any difference in size, Messrs. 

 Rothschild and Hartert have also identified a pair of birds 

 collected by A. S. Meek on the Utakvva River as P. marmo- 

 rata. The type of this species from the Astrolabe Mountains 

 (A. Goldie) is in the British Museum.

These specimens are perfectly similar to one of the typical 

 examples (specimen ^), a female, from Moroka, collected by 

 Doria ; they also agree with three males from the Owen 

 Stanley Range, 5000-8000 ft., collected by Mr. W. Good- 

 fellow. 



In two males from the Utakwa the wing measures 83 and 

 86 mm. respectively; in two females, 74 and 75 mm.; while in 

 specimens from the Owen Stanley Range three males measure 

 respectively 75, 76, and 78 mm., and one female (the typical 

 bird from Moroka) 69 mm. 



It will thus be seen that the Utakwa birds appear to be 

 slightly larger.
