This species was discovered by Delattre at Panama, and described by Bourcier in 

 1846 1. Its range must be very restricted, as we have no record of its occurrence 

 anywhere in the State of Panama except along the line of Railway which crosses from 

 the Atlantic to the Pacific side of the Isthmus. Here, however, it is not uncommon, 

 and has been observed at several points between Paraiso and Lion Hill Stations. 

 During a short stay at Obispo Station in April 1873, Salvin saw several birds of this 

 species frequenting the orange-trees near the station house,

This is a more northern form of A. edwardi, ranging from the line of the Panama 

 Railway to the confines of Costa Rica, and into the province of Talamanca in that 

 country. It is nowhere abundant, though Arce has sent us specimens from several
