longer, as might be supposed by a person desirous of proving the one 
to be more scansorial and migratory than the other. Perhaps the Eu- 
ropean bird is somewhat larger, and it certainly differs a little in colour. 
After one has studied the differences, he can easily select from a pro- 
miscuous assemblage of skins the European or the American specimens. 
But, after all, the differences are very slight, and certainly not such as 
to form good essential characters. Were the two species to be com- 
paratively characterized, they might be described as follows. 
T. europea. In the male the upper parts reddish-brown, faintly 
barred with dusky, the lower parts pale greyish-brown, the sides and 
abdomen barred with dusky and greyish-white, the fore neck and breast 
without bars, the lower wing-coverts and axillars greyish-white. 
T. lyemalis. In the male the upper parts reddish-brown, faintly 
barred with dusky, the lower parts pale reddish-brown, the sides and 
abdomen barred with brownish-black and greyish-white, the fore neck 
and breast more faintly barred, the lower wing-coverts and axillars 
greyish-white, barred with dusky. 
The following is a comparative view of the measurements of several 
American and European birds.
