The I'losely related .t^eiicra J'/in/itihrninti, Milrni/o, Ilii/rfn; and Daptrim 

 are iieeidiar to South America and the soutliern jMirtion of Middle America, 

 most of them liein,n' represented by two or mon; s]iecie,s. They all i'orm 

 a well-marked and jKHuliarly American grou[), for which I shall retain 

 Schlegel's term rolijlnifi. 



Their hahits are ijuite difl'eront in many respects from those of other 

 Fiih-oii.'uhi , for they eondiine in many r(!S])ects the habits of the gallinaceous 

 liirds and those of the N'ultures. They are terrestrial, running and walking 

 gracefully, with the exception of the s])ecies of Ihjicter and JJaptrius, which 

 are more arboreal than the others, and are said also to feed chiefly upon 

 insects, instead of carrion.
