3. Form from British New Guinea. (P. soror bartoni, 

 subsp. n.) 



Pacliycepliala soror Roths. & Hartert (nee Sclater), N. Z. 

 X. p. 103 (1903) [part.], xiv. p. 470 (1907). 



Male. Tail green, the black along the shaft widening out 

 near the extremity. 



Female. Ijike the female of No. 2 from the Utakwa 

 Valley. 



Though these races are closely allied they cannot be 

 united, and I have therefore named them as above. 



Messrs. Rothschild and Hartert [N. Z. xiv. p. 471 (1907)] 

 noticed the brownish-olive colour of the back in the female 

 of typical P. soror from Arfak, but did not separate the 

 British New Guinea form owing to lack of material.
