CAMEL (Camelus bactrianus). 



Tartars, and the single-humped camel, or dromedary, 



originally of Western Asia, 

 FIG. 188. but now domesticated in Asia 



and Africa ; this latter is the 

 species employed as a beast 

 of burden. 



The llamas are the American 

 representatives of the Camel- 

 ida3, true camels being found 

 only in the Old World. Sev- 

 eral species of llama occur in 

 the mountainous regions of 

 Western South America, and 

 some of them have been do- 

 mesticated by the natives, both for service as beasts of 

 burden and for the long, woolly hair obtained from them. 

 They are much smaller than camels, and have no humps 

 on the back.
