and to a less extent Hurylaemus and Sarcophanops, have a decided

front and smooth behind (laminiplantar); the hallux is weak ; the 
third and fourth toes are distinctly united, the claws are very short. 
The moderate wings have ten primaries in Calyptomena, eleven else- 
where, Zurylaemus having the eleventh very small; the secondaries 
are nine or ten; the tail of twelve rectrices is usually long and 
rounded, but is graduated in Psarisomus, short and square in 
Calyptomena. The adults have no aftershaft or down, the tongue 
is sagittate, and Sarcophanops has naked orbits. The plumage
