culmen rounded except basally, where contracted into a narrow 
ridge; tomia smooth; mandible with a lateral median groove. Nasal 
operculum rather narrow, its outer edge straight or but slightly 
convex basally, mostly hidden by frontal feathering, which extends 
about as far as anterior end of nostrils, forming a short point or antia 
on each side of mesorhinium. Tarsus clothed with short feathers, 
except posterior edge; inner toe very slightly shorter than middle 
toe, the outer toe still shorter, the hallux about as long as outer toe. 
Wing more than three times as long as culmen in adult males, about

males, slightly double-rounded or truncate in females, the rectrices 
moderately broad, rounded or subcuneate at tip.
