contained in any other collection (about ten skins from Costa Rica and 

 Chiriqui). Most of the birds taken have been collected at high altitudes, 

 in the heavy forests found in those regions. Mr. Bangs has one specimen 

 from Cariblanco de Sarapiqui (2,000 feet), and one was taken at Coliblanco 

 by Mr. Ridgway (5,000 feet). All other skins known from Costa Rica 

 are from much higher altitudes (7,000 to 8,000 feet). The single specimen 

 which I secured at Ujurras de Terraba was taken in the humid moss-cov- 

 ered forest at about 7,000 feet, right on the top of a cold wind-swept ridge 

 at the summit of the range. Another was shot in the same place but fell 

 down the side of a ravine and could not be found among the mass of 

 vegetation.
