This monotypic genus is easily distinguished by the peculiar 

 shape of the tail-feathers and by its long and slender claws. The 

 bill is stout and pointed ; its depth and width at the base are about 

 two-thirds the length of the exposed culmen. The wing is slightly- 

 pointed, the two outer primaries being longest and equal. The tail 

 is rounded at the tip, each feather being acuminated and about 

 two-thirds the length of the wing. The tarsus, which is pro- 

 portionately long, is about equal in length to the middle toe and 

 claw. Coloration : male and female different.
