The members of this genus are conspicuous by their black and 

 white colour. The bill is sharply hooked at the tip of the upper 

 mandible and furnished with black bristles at the base : the width 

 of the base is about two-thirds the length of the exposed culmen. 

 The wing is rounded, the second, third, fourth, and fifth primaries 

 longest and subequal, the first about equal in length to that of the 

 ninth. The tail is slightly rounded at the lip and about two- 

 thirds the length of the wing. The tarsus is about twice the 

 length of the exposed culmen and the hind toe and claw about 

 equal in length to that of the inner toe and claw. Coloration; 

 male and female similar.
