(3,706.) Type of S. macroptena, 
Famity SYLVIID. 
Bill slender, broad and depressed at the base, distinctly notched and de- 
curved at the tip. Culmen sharp-ridged at base. Frontal feathers reaching

spurious primary about half the 2d, which is shorter than the 7th. Lateral 
toes equal.

gape, sharp-ridged culmen, exposed oval nostrils, less adherent toes,
