scribed is in full spring plumage, without any clouding of the black 

 mask. It is very different from O. speciosa,^ Sol.

(No. 24,042.) Bill slender, conical, much as in G. mncgillivrayi, the culmen 

 nearly straight. First quill about equal to the 8th ; the 4th longest. Color

" Bright oil yellow ; head, especially on the sides, with the auricular region, 

 black ; quills blackish-brown ; beneath bright yellow, the sides brownish, 

 under wing coverts yellow ; bill black ; feet dusky flesh color. Length, 5.30 ; 

 wing, 2.40; tail, 2.30."— 5c/a/er. 



I have not seen this strongly marked species, which differs from G. trichas 

 apparently in the wider black mask, absence of hoary margin to the mask, 

 and in uniform yellow of under parts, including lining of wings. The tarsi, 

 toes, and claws are longer. In these respects, as well as in the coloration of 

 the under parts, it agrees with G. melanops ; but lacks the white head of the 

 latter, in which, too, the black extends rather less on the forehead than even 

 in G, trichas, 



Geoihiypis semijiavus, Sclater ( G. semijlavus, Sclater, Pr. Z. 1860, 273, 291. 

 —lb. Catal. 1861, 27, no. 168, Ecuador), is said to agree with the last men- 

 tioned, in most points, but to differ in paler olive above, and purer yellow 

 beneath. The black of the cheeks extends far down on the sides of the neck, 

 and on the forehead reaches to above the eyes. The three black-faced 

 (kothlypi, therefore, of the regions south of the United States, agree in the 

 purer and more continuous yellow beneath, and longer toes. An interesting 

 coincidence in this respect is seen with the chestnut-headed Dasileuteri — B, 

 rufifrons and G. trichas, the more northern species having the whitish belly ; 

 B dcllntrii and G. speciosa, from the middle region, having this more yellow ; 

 while the South American B. mesockrysus and G. semijlavus have the yellow 

 of greatest intensity.
