BIRDS—SYLVICOLIDAE—CONCLUDING REMARKS. 
305 
The specimens before me differ a little from Mr. Sclater’s description of Euphonia elegantissima. 
Thus, the throat is of the same dull steel blue color with the back ; the under parts have a 
strong tinge of chestnut. 
According to Mr. Sclater, the female is olive green, paler beneath ; the crown blue ; the 
forehead chestnut, margined behind with black, or much like the male.

CONCLUDING REMARKS. 
Having thus passed in review the well established species of North American Sylvicolidae, it 
may be well to mention those which claim such a place with greater or less propriety. Chief 
among these are the species described by Mr. Giraud as having been received from Texas, but 
which were probably taken in a more southern latitude, possibly about that of Tampico. Most 
of these doubtless at times wander as far as the Rio Grande, and several are described in the 
present report as having been taken on or near that river.
