The species on which this genus was founded is a small bird 

 and has a crest and patch of yellow in the middle of the crown. 

 The bill is proportionately small, the width being about two-thirds 

 the length of the exposed culmen. The wing is rounded, the 

 second, third, fourth, and fifth primaries longest and equal, the 

 first about equal in length to that of the sixth. The tail, which is 

 square at the tip, is about three-fourths the length of the wing. 

 The tarsus is about twice the length of the exposed culmen. The 

 hind toe and claw are about equal in length to the middle toe and 

 claw. Coloration : male and female similar.
