44. RHODACANTHIS FLAVICEPS, Rottech. 



Rhodacanthis flaviceps, Rothsch. Ann. & Mag. Nat. Hist. (6) x. 1892, p. Ill; Wilson & Evans, Aves 

 Hawaiienses, pt. vii. (1899) (description copied). 



Adult male. Head and neck dull golden yellow ; back and upper wing-coverts greenish 

 olive, shading into bright olive-green on the rump and upper tail-coverts ; wings and 

 tail dark-brown, the feathers externally margined with green. Chin, throat, and upper 

 breast dark wax-yellow ; abdomen and under tail-coverts yellowish green. Total length 

 about 7"5 inches according to Palmer's measuring in the flesh, but only 6 inches in skin ; 

 wing 3*8 to 3-85, tail 2*5, culmen 07 to 72, tarsus 0'95 to 1. 



Adult female. Underparts of a yellowish green, much paler than in the male ; above similar 

 to the male, but the head greenish olive like the back, only a yellow wash on the 

 forehead. The female is also a little smaller than the male, the wing measures only 36 

 to 3*7 inches. 



Young males closely resemble the adult females, but they are paler beneath and indistinctly 

 spotted or clouded on the breast. 



Palmer obtained a small series in the district of Kona, at the same places where R. palmeri 

 was first collected. The smaller size and yellow head of the adult male serve to distinguish 

 this species very easily from the much larger JR. palmeri with its orange-red head in the 

 adult male. 



Neither Wilson nor Perkins met with this bird.
