The bill in Attila is very strong, rather wide at the gape, and gradually converging 

 to the end, the culmen is nearly straight for most of its length, when it curves rather 

 abruptly into a strong hook ; there is a distinct subterminal notch on the tomia of the 

 maxilla, which is slightly convex ; the tomia of the mandible is slightly upturned, and 

 there is a notch near the end ; the nostrils are oval and open at the end of the nasal 

 fossa and partly covered by the setose supra-nasal feathers ; the rictal bristles are long 

 and strong. The third and fourth primaries are the longest in the wing, the second 

 <the fifth, first = the tenth ; the tail is slightly rounded. The tarsi are long, the toes 

 and claws rather slender ; the outer toe is united to the middle toe near the base, the 

 inner toe cleft to the base.

This name has usually been applied to the bird found in Eastern Mexico and 

 Guatemala and southward to Nicaragua ; but we believe that its range extends to 

 Chiriqui, and that it occurs in that country and in Costa Rica with the allied form 

 A. sclateri, but whether the two are found in the same woods remains to be proved. 

 The throat and chin in A. citreopygius are more or less greyish white, whereas in the 

 allied species this portion of the under surface as well as the breast is greenish 

 yellow, and the streaks not quite so well marked. Southern birds have a rather more 

 slender bill than northern ones; but the breast, in all specimens, is more or less washed 

 with greenish yellow.
