This Iianclsome hawk was fouiid iu the state of New Leon, one of the 

 most northern provinces of Mexico, by Lieutenant D. N. Couch, L^nited 

 States Army, and very probably extends its range northward into the terri- 

 tory of the L^'nited States. In fact, a sjjecimen is said to lia\'e been taken 

 in Arizona by Lieutenant "Wliipple's party. Not much is knoflai of its 

 habits, except that the nest is made in the tojj of a lofty tree, and that the 

 eggs are greenish-white, like those of Astiir. 



If Schlegel be correct in distinguishing two allied species, the bird here 

 refeiTed to will be known as A. ]}lagiata. (Baird.)
