This species was discovered by Delattre at Panama, and described by Bourcier in 
18461. 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 Arcé has sent us specimens from several
