This genus is distinguished by having an elongated crest and 

 the three outer primary- quills much reduced in length, but 

 about normal in width. The bill is depressed, the width at the 

 base being about half the length of the exposed culmen. The rictal 

 bristles are well developed. In the wing the fourth, fifth, aud 

 sixth primaries are longest and subequal. The tail is proportion- 

 ately long, being nearly seven-eighths the length of the wing. 

 The hind toe and claw are about equal to the middle toe and claw, 

 which are about two-thirds the length of the tarsus. Ooloration : 

 mule and female similar.
