This is one of the rarities among the flycatchers, not only in Costa Rica, 

 but throughout its range, but five specimens of it ever having been taken 

 in Costa Rica, three by Underwood, which are in Mr. Bangs' collection, 

 and two by myself at El Hogar. 



It seems that in Costa Rica it is confined to the Caribbean lowlands, 

 with very likely a continuous range up from Panama, although it has never 

 been taken in intermediate localities. I did not take, or to my knowledge 

 see it in Talamanca.

This peculiar bird has a remarkably large and variable range in Costa 

 Rica, being found over both the Caribbean and Pacific lowlands and up on 

 the eastern slope of the mountains of northeastern Costa Rica, as high 

 at least as 5,000 feet. However, it seems to be absent from the north- 

 western portion of the country, no specimens having been taken in Guana-
