53. Melanopitta sordida (95). 



[Zamboanga, 3 , March : iris chocolate ; bill black ; legs brownish 

 grey, 3 2 > March, April, and May.] 



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 6th, 7th, and 8th primaries are 

 scarcely tipped with black ; and the first five primaries have double 

 the amount of white that exists on the primaries of the i'emale. On 

 examining Luzon and Negros examples with the sexes noted by 

 Dr. B. Meyer, the same character differentiates the sexes. In 

 Borneau individuals of M. muelleri (sex determined by Mr. Everett) 

 the sexes can be discriminated by the amount of white on the 

 remiges. In M. cucullata some of my 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.
