FLYCATCHERS. 301 



interior does its range appear to extend much if any higher. 

 . . . The nest is disposed in a horizontal fork. Dr. Whea- 

 ton ... is of the opinion, that the eggs of acadicus average 

 a little longer and slenderer than those of traillii, and have 

 perhaps a yellower buff tinge. ... Of the Acadian he 

 says : ' It is never found in company with, or in such local- 

 ities as are frequented by, the Traill's. In all cases it is 

 found in upland woodland, preferably, and I might almost 

 say as far as my observation extends, in beech woodland. 

 I have never seen it even during the migration in other 

 places.' "

a. About five inches long or less. Crown-feathers, erec- 

 tile. Tail, even. Coloration, so far as known, like that of 

 other small Flycatchers (Frnpidonaces^, but apparently with 

 little olive tinting above, and no yellow beneath. [Moreover, 

 vrith no huffish suffusion, etc. ?] Outer web of the outermost 

 tail-feather (and possibly, but not probably, more of the tail), 

 white. 



c. Soon after noon, on the twelfth day of May, 1875, whilst 

 walking about my father's place near Boston, I caught sight 

 of a small Flycatcher in some shrubbery which stood near an 

 open field, and which consisted of barberry-bushes, a white 

 birch, etc., while near this place were several apple trees, 

 pines, isolated oaks, and other trees. By his habits, his erected 

 crown-feathers, and his style of coloration, I knew him to be 

 a Flycatcher ; on observing his size and even tail, I ascribed 

 him to the genus Empidonax (or a closely allied genus) ; and, 

 on noticing that his tail was edged with white to the depth of 

 an eighth of an inch or more, when closed, I believed him to 

 be a new species. In Dr. Coues's " Key to North American 

 Birds," but two Flycatchers, ever found in the United States, 

 are mentioned, who have the outermost web of the tail white. 

 Of these, Empidonax obscurus* Wright's Flycatcher (a bird 

 of the southwestern United States), is much larger than pyg- 

 mceus — for I noticed a Pewee, who chanced to alight beside
