Iris, in the adult, light reddish brown ; bill and tarsus black. 

 Length about 9*5 centims., wing 5'4-56 centims. The adult birds 

 of both sexes are deep black on the upper surface, with a faint tinge 

 of bluish green, most marked on the wing. The middle line of the 

 breast and abdomen is washed with pale buff. In the young birds 

 the black of the upper surface is replaced by a dull olive-brown, and 

 the outer webs of the secondaries are bordered with olive-green. 

 This edging becomes narrower on the primaries, and is absent 

 altogether from the first two or three. 



B. hypoleucum appears to be abundant in the Sulu Archipelago, 

 and is almost always to be found in the cocoanut groves, hunting at 

 the crown of the palms for insects, in company with Cinnyris 

 juyularis.

 5"2 centims. 



In three or four of the above males there is a patch of metallic 

 blue feathers at the upper and outer angle of the eye, forming a 

 partial eyebrow, and in most skins some faint trace of this is to be 

 seen. In several individuals also there are scattered metallic blue 

 feathers in the frontal region. There is no tendency whatever to 

 this metallic colouring on the head in any of a large series of C. 

 frmata that I obtained from Celebes and the islands eastward to 

 New Guinea. 



The present species is extremely abundant in Sulu Island. As 

 far as I am aware, it has not been recorded from Palawan, where 

 C. aurora probably replaces it.
