This handsome species has a wide range in Costa Rica, covering prac- 

 tically the whole of the country between the altitudes of 1,000 and 4,000 

 feet, on both the Caribbean and Pacific slopes. It seems to descend lower 

 on the Pacific side, having been taken at Pozo Azul, which is only about 

 200 or 300 feet above sea-level, but on the eastern side the lowest record 

 is from Carrillo, at about 1,200 feet. Its habits are the same as those of 

 the other species of the family found in Costa Rica, the birds assembling 

 in small flocks in open woodlands and among scattering trees, rather than 

 in the heavy forest.

This race of Dacnis cayana is perfectly good in every respect, being 

 easily distinguished from ultramarina by the decidedly different shade of 

 blue in the males. It is confined to the Pacific coast and lower foot-hills 

 of southwestern Costa Rica, from the Rio Grande de Tarcoles southward,
