BIUDS — SYLVICOLIDAK — CONCLUDING REMARKS. 



305 



The specimens before me difler a little from Mr. Sclater's description of Enphonia elegantissima. 

 Thus, the throat is of the same dull stcil blue oolur 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. 



List of specimens. 



CONCLUDING REMAEKS. 



Having thus passed in review the well established species of North American S)/lvlcolidae, 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.
