They are put first in the Vertebrate Group, though we have spoken of the birds and fishes before them, because they were made on the Fifth Day.
They are generally—for we must not forget the whale—covered with hair or fur, and they feed their young with milk. First of the classes into which the Mammalia are divided, we place the Four-handed creatures—apes and monkeys.
Second, the Hand-winged; the bats.
Third, the Flesh-eaters; many of them beasts of prey of the Cat-kind and of the Dog-kind.
Fourth, the Herbivora; animals which feed upon grasses.
Fifth, the Horse-tribe.
Sixth, the Ruminants; animals which chew the cud.
Seventh, Elephants.
Eighth, the Pig-kind, including the Hippopotamus which is believed to be the creature called Behemoth.
Ninth, the Pouched animals.
