 hood of the east coast, in woods and moist places on the banks of rivers ; 

 it attains a length of from five to six feet. Another American species that 

 lives on mountains was found some years ago by Rodlin, Ann. des Sc. nat.

Fossil species of Tapir occur in tertiary formations. Tapirus giganteus 

 of CoviER belongs to the genus Dinotherium Kaup, which with the molars 

 of the tapu- has also two very large tusks in the lower jaw directed down- 

 wards. It belongs to the tertiary period. By Owen it is classed with the 

 Proboscidea.

 strata, related to ta2nr, with all the feet tridactylous.)

AU the species of the genus horse belong to the old world, and are at 

 home on the wide mountain-plains of Asia and Africa. They live together 

 in troops, are very swift, and feed chiefly on species of grass. The intes- 

 tinal canal is wide and long ; they have a simple stomach, a large ccecum, 

 and no gall-bladder. 



1 In young horses there is in both jaws a small anterior molar {wolf -tooth of Dutch 

 writers); see L. Bojani Adversaria ad dentitionem Equini generis et ovis domesticce 

 spectantia; Nov. Act. Acad. Cces. Leap. Car. Xll. 1825, pp. 697 sqq.
