553. Tlira§aetiis liarssyia (Linn.). 



" Teliuantepec (Almoloya); October, 1868. 



"Iris dark brown ; cere and bill black ; feet yellowish- white. 



" The Harpy Eagle is exceedingly rare in Mexico, of which there is 

 probably not a native bird ; and its capture is truly a work of chance. 

 The isolated birds which have been found there up to this time have 

 probably been brought --by some atmospheric disturbance, which has 

 driven them beyond the natural limits of the zone in which they live." 



554. Mypotriorclais alfoigMlaFis (Daud.). 



" Tehuantepec (Tapana) ; Oaxaca ; June and August. 



" Iris dark brown ; bill blackish-blue ; cere, lores, and orbits yellow j 

 feet orange-yellow. 



" Quite universally dispersed in the warm and temperate districts of 

 Mexico; this falcon mounts at times up to the cold regions. It is quite 

 rare in the dry plains which border upon the Gulf of Tehuantepec, and 

 becomes more common as you approach the mountains. It is a resident. 

 It mainly attacks other birds, and vigorously hunts pigeons."
