- 8. Description of a New Genus and Species of Oscines 
from Costa Rica. By Osperr Savin, 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.
