Carriker : List of the Birds of Costa Rica. 357 



this name in Costa Rica, but the only one at which birds have been 

 collected is the present one. It is really the name of a small valley 

 or three small valleys at the head of the Rio Ceibo, on which is situ- 

 ated Buenos Aires de Terraba. The locality called Ujaras on my 

 labels (no other collectors have used it) is the crest of the mountain 

 above these valleys at an altitude of from 7,000 to 8,000 feet. It is 

 a region of broken, precipitous mountains, ending in sharp ridges, the 

 whole densely covered with a moss-covered, rain-soaked jungle, almost 

 impossible to penetrate, but containing many rare species of birds.

History of the Ornithology of Costa Rica. 



Up to the year i860 nothing was definitely known of the ornithology 

 of the region known as Costa Rica, and in truth but little was 

 known of Central America as a whole. Something of southern Mexico 

 had been learned through the researches of Messrs. Salle, Botteri, and 

 Boucard, while Prince Charles Lucien Bonaparte had published a 

 small list of birds (39 species) from Guatemala, some of which were 

 new. Delattre had done some work in Nicaragua in 1853, the results
