Frontal feathers encroaching on the nasalmembrane and partially concealing the nostrils ; those on theupper part of the head rather long; bristle-feathers at the baseof the upper mandible. Wings long, broad, when extendedsemicordate. Primaries ten, the first minute, the next threelongest; the first five rounded, the rest emarginate; second-aries eight, the outeremarginate, the innertapering, the sixthmuch elongated.
