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

 The moderate wings have ten primaries in Calyptomena, eleven else-

 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
