McClelland, 1839, and Deignan, 1955b), as had Stresemann (1926) 

 because of the "intermediate [systematic] position" of C. inopina 

 (type-locality: Ma-fu-ling, Hupeh, China; Thayer and Bangs, 1909) 

 and the similarities in nest structure. 



All authors who have discussed C. w. papuensis, however, have 

 overlooked one very important character. The type and paratypes 

 (examined in the American Museum of Natural History and the 

 Bogor Museum) from Hollandia and the Idenburg River area have 

 three toes instead of four. 



I believe the three-toed birds represent a full species, which is 

 characterized thus below.
