This beautiful trogon is confined to the southwestern portion of 

 Costa Rica, thence southward into Chiriqui. It has never been taken 

 farther north than Pigres and San Mateo, where it is very rare, but 

 becomes commoner southward, especially in the lower parts of the 

 Terraba Valley. It does not usually go much above 1,000 feet above 

 sea-level. It is a woodland species, with habits similar to the pre- 

 ceding, although it is usually found higher up in the trees than any 

 of the lowland species.

Mr. Bangs has recently separated the Costa Rican T. melanocephalus 

 from the northern form on the color of the head and neck, which in 

 the Mexican birds is pure black, while a large series of Costa Rican 

 specimens shows it to be uniformly grayish to blackish slate-color. 



This species is confined entirely to the Nicoya peninsula and 

 southern Guanacaste, no specimens as yet having been taken on the 

 mainland side of the Gulf of Nicoya. Costa Rica is the southernmost
