HYPHANTORNIS 



S99 



Genus XYIII. HYPHANTORNIS. 



Very similar to the last seven genera I have recognised, with a few 

 hair-like plumes on the nape and back of neck ; bill fairly stout ; culmen 

 broad, rounded, moderately curved, the base ending in a shallow angle on the 

 forehead ; nostrils opening in front of the frontal feathers ; cutting edges of 

 mandibles slightly waved ; wings rounded ; primaries 1 more than a third of 

 the length of 2 and reaching beyond the end of the coverts, 3, 4, and 5 

 longest and about equal. Tarsi, feet and claws fairly strong, pale brown or 

 fiesh-colour ; hind toe with claw equal in length to middle toe with claw ; 

 claws sharp and much curved. Plumage of the sexes alike in colouring of 

 the wings and tail, which have pale edges to all the feathers ; but the other 

 parts, especially the head and neck, are very dissimilar during the breeding 

 season, when only the males have the sides of the head and a portion of 

 the throat black.
