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.

(Delattre +), Sucuya (Nutting “); Costa Rica (Carmiol) ; Panama, Chiriqui (Arcé). 
This name has usually been applied to the bird found in Eastern Mexicc 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.
