 Museo Nacional de Costa Rica, from the Matina River and from Bebe- 

 dero, reported by Mr. Cherrie to be this species. There are no specimens 

 in this country from Costa Rica, nor is it reported south of Guatemala 

 in the "Biotogia" and the "Catalogue of the Birds of the British 

 Museum."

This swallow is found at various points along both coasts wherever there 

 are cliffs or rocky bluffs affording nesting sites. Such conditions are much 

 more common on the Pacific coast than along the Caribbean. The birds 

 do not confine themselves to the coast, but go up the large rivers for long
