This is an extensive genus embracing upwards of twenty species, 

 of small size, which extend nearly all over the Neotropical Region. 

 The bill is rather sbort and much broadened ; the gape is well 

 armed with rictal bristles ; the wings are rather long, and the tarsi 

 sbort. Nearly all the males show a brightly coloured, half-con- 

 cealed, vertical crest, which is in some cases absent, or differently 

 coloured in the female.
