Medium-sized Kakatoeine birds of white coloration, with medium bills, long 
wings, long tail and small legs and feet. 
The distinctive features of the genus are the long recurved crest, white 
coloration and naked cere. 
The bill is comparatively narrow with a projecting long tip, succeeded by 
a notch and then straight edge ; the cere is small but naked, the nostrils 
placed high up on sides of bill in the cere. The under mandible is deep and 
narrow, the sides straight, the tips with sinus between, but the tips do not 
project like teeth. The lores are feathered but there is a small bare space 
round the eye.
