the centre of Vera Paz, frequenting'the higher ranges (Leyland). Guatemala: 

 Coban, Vera Paz ; found only in the coast districts, does not extend its range 

 into the central districts (Salvin). Costa Rica; only in the warmer and 

 more retired parts of the country, especially in the neighbourhood of the 

 coast ; seen in San Juan del Norte, and some specimens on the western side 

 (Pacaca) ( Von Frantzius). Panama (M* Chlland); New Granada (Salmon); 

 Bogota {Sclaier); Santa Martha (Verreaux); Trinidad, met with on a 

 journey from Port of Spain to the east coast (E. C. Taylor); British 

 Guiana (Schomburgk) ; by no means common in Demerara (Bonyan).

N. America. " Quite common along the Atlantic and Gulf coasts from 

 North CaroUna to Mexico. It does not occur on the Pacific coasts of the 

 United States, though given by Douglas as being abundant on the Columbia 

 river; indeed it has not, that I am aware of, been detected west of the 

 Rocky Mountains. It is, however, as Dr. Gambel states, very common 

 about the Gulf of California ; and at Mazatlan, particularly, he saw it round 

 the town in large companies. On the Atlantic coast it is not often met 

 with further north than Wilmington, N.C. I could not detect it near 

 Norfolk, Va., nor could I understand that it was known ever to occur 

 there. Accidental specimens have been taken, two on the coast of Mas- 

 sachusetts and one in the Bay of Fundy ; but such occurrences are very 

 rare. Along the coast of all the Southern States, from North Carolina 

 to Texas it is much more abundant than R. aura, even where, in the 

 interior of the same state, it is far less frequent. Along the banks of 

 the Mississippi and its tributaries, as far as Ohio to the east and Illinois 

 to the north, it is found more or less abundantly at certain seasons. 

 It is met with in several of the West-India Islands, though rare in 

 Jamaica " {Brewer, in the 3rd vol. o^ N.- American Birds, p. 362); Florida 

 ( G. C. Taylor) ; on the Rio Grande, Texas, about equally common with 

 C. aura, but towards San Antonio, much less so {Dresser). 



C. America. Orizaba, Mexico {Botteri) ; Mazatlan, " may be met with 

 in all Mexico, but is more common in the tierras calientes {Grayson,
