BIRDS — SYLVICOLIDAE — CONCLUDING EEMARKS. 



305 



The specimens before me differ a little from Mr. Sclater's description of Euphonia elegcmtissima. 

 Tkus, the throat is of the same dull steel blue color with the hack ; 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. 



List of specimens. 



CONCLUDING EEMARKS. 



Having thus passed in review the well established species of North American Sylvioolidae, 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. Griraud 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 Eio Grrande,, and several are described in the 

 present report as having been taken on or near that river.
