Adult male. Intermediate between S. sulphuratus and S. marshalli, 

 resembling the former in the plumage of the sexes being similar, and the 

 yellow sides of the forehead not meeting. It differs from S. sulphuratus and 

 agrees well with S. marshalli in the greater amount of yellow on the upper 

 and underparts. 



Above, olive yellow with faintly marked dusky shaft-stripes to the 

 feathers of the crown and mantle ; lower back and upper tail-coverts 

 uniform, the former inchning to bright yellow. Tail blackish brown, with 

 narrow, rather dull yellow edges. Wing blackish brown, the lesser coverts 

 like the mantle, and the other feathers edged with the same shade of yellow 

 as the lower back. Sides of head and neck mostly uniform olive yellow, 

 with the sides of the forehead, eyebrow, and patches on the front and back 

 of the cheeks bright canary yellow like the chin, throat, breast, thighs and 

 under tail-coverts ; crop very faintly tinged with olive. Iris brown, bill 

 yellowish, slightly browner above, tarsi and feet brown. Total length 5-2 

 inches, culmen 0'45, wing 3, tail 2-2, tarsus 0-65. <? , 26. 4. 97 ; 2 , 19. 4. 97.

Adult female. Slightly duller ; mantle more streaked, less yellow on the 

 head, crop rather more olive ; flanks with a few obscure dusky streaks.
