AI, OR THREE-TOED SLOTH. These animals are very appropriately named, for their movements are painfully slow. They have 



.scythe-shaped claws on each foot, and move with considerable labor from branch to branch. The positions they assume are well shown in 

 the picture, and the female with the young one seems to have a specially difficult task in moving about. {Bradyfus tridactylus.)
