The legs and feet are yellowish red or orange ; the claws 

 blackish horny ; the irides dark brown ; the lower eyelid 

 slaty blue ; the bill pale horny or slaty, dark at point ; nostril 

 scale dark orange ; cere brighter and yellower orange ; behind 

 the eye is a long space of naked yellow skin. The males have 

 a large blunt spur on either leg. The females want this, but 

 so far as plumage is concerned are precisely like the males. 



The Plate is on the whole good, but the legs are not suffi- 

 ciently orange, and the bright orange yellow cere and nostril 

 scale are ignored in the male, though indicated in the female.
