770 FElNGILLIDiE. 



somewhat smaller size and uniform under tail-coverts: "upper 

 mandible brown, the edge of the upper and lower mandible clear 

 yellow ; iris greyish brown " (Burmeister). Total length 7 inches, 

 culmen 0-55, wing 2-9, tail 3*7, tarsus 0-9. 



The uniform under tail-coverts do not seem to be absolutely con- 

 stant in this race, and a female from Pelotas has them distinctly 

 streaked with blackish. It appears to me very doubtful whether 

 E. sphenurus is separable even as a race from E. macrurus. 



Hab. From Lower Amazonia throughout Brazil to Bolivia.
