Head and occiput crested. Nude skin around eyes. Bill long, curved, stout, broad at base.

 stout; claws strong. 



Genus XI. BYCANISTES.

 Gonys straight for two thirds the length from base ; it then turns abruptly upwards, and follows 

 the curve of the gape to the point. Casque enormous, longer than bill, swollen and rounded 

 on top, compressed anteriorly, having several irregular transverse grooves ; it rises a short 

 distance from tip of maxilla at an acute angle, then curves backwards to the centre of the head, 

 and returns to base of maxilla by a steep angle. Wings ample, long, second and third primaries 

 equal and longest. Tail broad, long, much rounded. Nude skin around eyes. Tarsi short, 

 stout, as are the toes, and both covered with strong scales.

 longest. Tail rather long, much rounded. Tarsi and toes short, covered with strong scales. 



Genus XIII. BHYTIDOCEBOS. 

 Bill long, nearly straight, graduated to a point. Base of maxilla and mandible grooved

 Wings ample. Tail long and rounded. Tarsi short, stout. Toes rather long. Claws strong, 

 curved. 



Genus XIV. ANOKRHINUS. 

 Head covered by a long loose bushy crest. Bill moderately long, stout, curved on culmen. 

 Casque extending over half the maxilla, highest at its anterior end, whence it inclines gradually 

 backward to the base of bill. Skin around eyes, cheeks, and throat naked. Wings long ; fourth 

 primary longest ; secondaries nearly as long as the primaries. Tail long, broad, and rounded.
