8. Description of a New Genus and Species of Oscines 

 from Costa Rica. By Osbert Salvin, M.A., F.R.S. 



[Received April 17, 1877.] 



The ornithology of Costa Rica has lately attracted much attention ; 

 and it might have been supposed that our knowledge of this subject 

 was tolerably complete. During the past seventeen years many large 

 collections of birds have been made in that Republic ; and the 

 results derived from their examination have been published by Dr. 

 Cabanis' in Germany, and by Mr. Lawrence" in America; while 

 several new species have been brought to notice by Mr. Sclater and 

 myself^ in this country. 



It appears, however, that the mountainous districts of Costa Rica 

 have still attractions left for the naturalist, as will be manifest from 

 the remarkable new form which I now proceed to describe.

Rostrum debile, angustum, glabrum, valde aduncatum, maxillcB apice 

 dentato : nares apet-tcB : setce rictales breves. Alee rotundatce :
