Hemignathus affinis, Rothsch. Ibis, 1893, p. 112 (Maui). 



Adult male. Top of the head bright gamboge-yellow, almost golden yellow, passing into 

 yellowish green on the nape and hind neck, which colour is not gradually, but somewhat 

 abruptly, terminated by that of the back, which is greyish olive-green without yelloAv, 

 becoming brighter and greener on the upper tail-coverts. Quills and rectrices deep 

 brown, bordered with bright olive-green. Lores black, connected by a black band 

 across the forehead, which is distinctly broader than in II. hanapepe 3 Wils. A very 

 tiny black chin-spot. Throat bright yellow, gradually passing into a sulphur-yellow on 

 the abdomen and pale yellow on the vent and under tail-coverts. Sides of the body 

 tinged with greenish olive. Iris dark brown. Bill blackish brown, slate-colour at base. 

 Tarsi and feet dark grey with a yellowish tinge. 



Adult female. Quite different from the corresponding sex of II hanapepe, Wils. Above 

 olive-green with a greyish shade, brighter and more green on the upper tail-coverts ; on 

 the forehead from the base of the upper mandible runs a bright yellow line to just above 

 the eyes. Lores dusky. Sides of the head yellowish. Chin and throat bright yellow ; 

 middle of breast and abdomen pale yellow, much like " Naple's yellow " (Ridgw. Nomencl. 

 Colors, pi. vi. fig. IS) ; sides of breast and flanks washed with olive, under tail-coverts 

 slightly so. Under wing-coverts yellowish white.
