(From 



Order 4. Rhei- 

 formes. RHEAS. 



These are the New- 

 world ostriches (Fig. 

 481). There are three 

 species inhabiting the 

 pampas of South 

 America. They are 

 smaller than the true 

 ostriches, but their 

 habits are quite similar. 

 Order 5. Casuari- 

 iformes. CASSO- 

 WARIES and EMEUS. 

 The two families in 

 this order contain 



ostrich-like birds; the DROM^ID^: or emeus (Fig. 482), which 

 are, next to the ostriches, the largest of living birds, are confined 

 to Australia ; the CASUARIID.E or 

 cassowaries inhabit New Guinea 

 and neighboring islands. The cas- 

 sowaries usually possess a bony, 

 helmet-like knot on the head, and 

 have brightly colored lobes on the 

 head and neck; these are absent in 

 emeus. 



Order 6. Crypturiformes. TIN- 

 AMOUS. About forty species of 

 tinamous are known. They re- 

 semble game-birds in appearance 

 and are called partridges by the 

 natives of southern Mexico and 

 Central and South America, where 



they live. The powers of flight of FlG 4S2 ._ Emeu>Droma;usnova; . 

 the tinamous are not well devel- hoiiandia. (From Evans.)
