NOTES ON THE BIRDS OF TENNESSEE — WETMORE 201 



5,700 feet on Inadu Knob on June 23, and one was recorded at 6,100 

 feet on Roan Mountain, September 12. 



In the fourth edition of the A. O. U. Check-list (1931, p. 211) 

 the olive-sided flycatcher is listed as NuttdlJ'Ornis mesoleueus 

 (Lichtenstein) following Hellmayr,^^ who based this on Muscicapa 

 mesoleiwa Lichtenstein.^^ More recently, however. Van Rossem ^* has 

 located Lichtenstein's type in the Berlin Museum to find that it is 

 a species of South American flycatcher. This circumstance allows 

 return again to the familiar name horealis as the specific term for this 

 attractive flycatcher. 



The bird from Cosby Knob, an adult male in good plumage, is 

 very small, measuring as follows : Wing 100.8, tail 65.9, culmen from 

 base 17.5, tarsus 15.5 mm. 



After examination of a large series of specimens, the contention 

 of some that there are eastern and western forms of this flycatcher 

 in my opinion is not upheld. It is true that the specimens with the 

 longest wings come from the west, and those with the shortest wing 

 measurement from the east, so that by averages a slight difference 

 between series from the two areas is evident. The overlap in size in 

 skins from the two areas is such, however, that the majority of indi- 

 viduals might be classed in either group, only a few specunens among 

 the extremes of large and small being susceptible of separation. In 

 these circumstances I do not consider recognition of two races war- 

 ranted. The statement is made only after examination of a large 

 number of skins.
