Also spelt Plateihia Bonaparte, Consp. Gen. Av., Vol. 11. , p. 149, 1855. 
Plataleine birds with the top of the head feathered, but no crest ; other 
characters as in Spatherodia. 
The bill differs somewhat in construction : the nostrils are more linear 
and the groove is less marked, the linear channel much less pronounced 
and nearer to the edge of the upper mandible. 
The top of the head is fully feathered but the loreal region and round 
the eye is bare as is also the chin and throat. 
The wing-formula is the same as in Spatherodia^ but the wing is about 
twice the culmen-length, while the tail is comparatively longer than in 
Spatherodia. 
The metatarsus is less than one-third the length of the wing, whereas 
in Spatherodia it is more.
