640 ON THE OENITHOLOGT OF THE PHILIPPINES. [1878. 



This species has the black central abdominal patch much more largely developed than in 

 M. muelleri ex Borneo. In no other respect does it appear to differ. The extent of pure white 

 on the quills is dependent on sex. Of fourteen individuals with the sex noted by Mr. Everett, 

 nine are males and five are females. The primaries of the male have a much greater white 

 surface than is found in the primaries of the female. The sixth, seventh, and eighth primaries 

 are scarcely tipped with black ; and the first five primaries have double the amount of white 

 that exists on the primaries of the female. On examining Luzon and Negros examples 

 with the sexes noted by Dr. B. Meyer, the same character differentiates the sexes. In Bomean 

 individuals of M. muelleri (sex determined by Mr. Everett) the sexes can be discriminated by 

 the amount of white on the remiges. In M. cucuUafa some of ray examples exhibit a maximum 

 of white on the quills and the others a minimum ; but as none have had their sexes determined 

 by dissection, I am unable to affirm that in that species the same law holds good. In two 

 Zamboanga skins the green of the breast and flanks is assuming the blue tint so prominent in 

 the large representative form M. steerii.
