Mr. Hellmayr in his paper on the Birds of Trinidad^ considered 
the birds from the Orinoco (Caicara), as intermediate between the 
typical mystaceus and mystaceus insularis, but the series in this ^luseum 
and that of the American Museum does not confirm that opinion. I am 
unable to find any differences bet\veen birds from Caicara (on the 
upper river), or birds from Las Barrancas (in the delta region), and 
birds from Trinidad. 
Adult birds have the eye seal brown; bill, maxilla black, and 
mandible pinkish flesh color ; feet delicate greyish flesh white, claws 
greyish white. In an immature male taken at Las Barrancas August 3. 
1907, both mandible and maxilla are blackish. 
This little flycatcher frequents the undergrowth in heavily wonded 
districts.

On the writer's first expedition to the Orinoco, a single specimen 
was collected at Nericagua above the falls of Maipures : this and
