FAMILY 108. CAKIAMID^E. (1 Genus, 2 Species.) 

 GENERAL DISTRIBUTION. 



1 .2 



The genus Cariama (2 sp.), consists of remarkable crested birds 

 inhabiting the mountains and open plains of Brazil and La Plata. 

 In the British Museum Catalogue of the Birds of Prey, they are 

 classed as aberrant Falconidae, but their anomalous characters 

 seem to require them to be placed in a distinct family, which 

 seems better placed among the Waders. 



FAMILY 109. AEAMID^E. (1 Genus, 2 Species.) 



GENERAL DISTRIBUTION. 



The Guaraunas are birds which have somewhat the appear- 

 ance of Herons, but which are usually classed with the Rails. 

 They are now, however, considered to form a distinct family. 

 The only genus, Aramus (2 sp.), inhabits the Neotropical region, 

 from Mexico and Cuba to Central Brazil.
