90 REVIEW OF AMERICAN BIRDS. [PART I. 
more distinct; the colors above possibly a little darker, with more 
reddish. 
The series at my command of the European C. familiaris is 
not sufficiently large nor perfect enough to permit any very satis- 
factory comparisons. ‘The bill, however, appears longer and higher 
than in eastern C. americana. The claws are longer, and the tai] 
shorter, not equalling the wings, instead of exceeding them. The 
first quill is longer, its exposed portion being half that of the second, 
instead of considerably less. The coloration is exceedingly similar ; 
the central light streaks of the feathers above are, however, less 
distinct, being not so white, and more pervaded by the ferruginous. 
The under parts are more ashy, and the rusty of the crissum perhaps 
less prominent. 
Certhia costz is, in reality, more nearly related than C. familiaris 
to our species in color and length of tail. This differs again in still 
larger bill and claws, and in a purer white of the under parts. The 
three, however, are so very closely related as almost to be entitled 
to consideration as races of one species.

This species will be readily recognized on comparison with the 
United States species by its much darker color above, and especially 
the deeper shade of brown on the rump, and apparently its greater
