There are two kinds of Sloths, which are principally 

 diftinguifhed by the number of their claws. — The one, 

 called the Ai, is about the fize of a Fox, and has three 

 Jong claws on each foot : Its legs are clumfy, and auk- 

 wardly placed •, and the fore legs being longer than the 

 hind, add greatly to the difficulty of its progreffive mo- 

 tion : Its whole body is covered with a rough coat of 

 long hair, of a lightilh-brown colour, mixed with white, 

 not unlike that of a Badger; and has a black line down 

 the middle of the back ; its face is naked, and of a dirty 

 white colour; tail fhort ; eyes fmall, black, and heavy. 

 It is found only in South-America. 



The Unau has only two claws on each foot: Its head 

 is fhort and round, fomewhat like that of a Monkey ; its 

 ears are fhort ; and it has no tail. It is found in South- 

 America, and alfo in the Ifland of Ceylon. 



The flefh of both kinds is eaten. They have feveral 



ftomachs, and are faid to belong to the tribe of rumi- 

 nating animals.
