externo. (Deser. femine ex Atrato, Colombia, U.S. Nat. Mus.) 
Hab. Panama, R. Truando (W. S. Wood).—Co.tomBia. 
We have to thank. Mr. Ridgway for sending us two specimens, both females or 
young males, obtained by Mr. A. Schott, one at Carthagena, the other on the R. Atrato. 
They doubtless belong to the same species as that referred to by Cassin as occurring 
on the Rio Truando and allied to 7. atricapillus. T. pulchellus, which was described 
from a Carthagena specimen, has a very limited range in Northern Colombia. 
¢. Minores: rostrum mediocre; ale rotundate ; ptilosis plerumque albo et 
nigro transfasciata ; sexus dissimiles.
