Carriker : List of the Birds of Costa Rica. 707 



type by Arce at Tucurriqui in 1863 or 1864. The first one taken after 

 that was a d 71 collected at La Concepcion de Jimenez by Geo. K. Cherrie, 

 Jan. 10, 1890 (Coll. U. S. Nat. Mus.), and in June, 1892, a female was 

 secured at Jimenez by C. F. Underwood (Bangs Coll.). Lastly, Mr. C. H. 

 Lankester secured a specimen at El Hogar, not far from Jimenez, in 1907. 

 The U. S. National Museum possesses another skin from eastern Nica- 

 ragua, collected by Nutting. Nothing is known of it in life, more than 

 that it is an inhabitant of the heavy forest, with habits perhaps similar 

 to Myiobius or Mitrephanes.

Eighteen skins. 



This is the common Myiobius of Costa Rica, being found on both coasts 

 up to an altitude of about 3,000 feet on the Caribbean slope and 2,000 feet 

 on the Pacific. It is found only in the forest, usually near a little brook, 

 flitting about among the low limbs of the trees and shrubbery. The birds 

 are very silent; in fact I do not think I have ever heard them utter more 

 than a faint chirp.
