87. Empidonax pusillus trailli. 
First plumage: male. Above olive-brown, the feathers of the crown 
with darker centres. Wing-bands light reddish-brown. Throat, breast, 
and sides ashy, tinged with olive upon the breast and sides. Abdomen, 
anal region, and crissum pale sulphur-yellow. Distinguishable from E. 
acadicus in first plumage by the darker color of the upper parts, especially 
of the crown, and by the entire absence of the narrow transverse bands 
upon the back. From a specimen in my collection shot at Upton, Me., 
July 21, 1874.
