Anabates, Temm. 



Leucopthalmus, Max. 

 There is no distinctive mark between the skeletons of Dendrocolaptes and Anabates 

 that I have been able to discover, except in the lateral processes of the palatine bones 

 being longer, the shape of the bill, in the nostrils of the former being oval, while in the 

 other they are rounded, and in the ulna being very slightly longer in proportion to the 

 humerus.
