428 Birds of Celebes: Campopliagidae. 



of course nothing to do with mimicry. Either, one form has given rise to the 

 other without change of coloration, or, the two forms have independently deve- 

 loped in coloration in the same direction, owing to the action of light upon the 

 feather-pigments, as mentioned supra under Graucalus bicolor. 



The traces of bars in the dress of the female are especially interesting as 

 compared with the longitudinal shaft-streaks on the breast of the young, the 

 former appear to point to more recent, the latter to more ancient ancestry, 

 though we are not yet able to define this more exactly. 



Another species which corresponds in coloration sex for sex somewhat 

 closely with L. leiicopi/gialis is Muscicapula westermamii.
