CABNIVOBOUS QUADBUPEDS. 



64. We now come to Quadrupeds [quatuor, four ; pes, 

 foot), four-footed Mammals. This sub-class includes most 

 of the animals of any size that walk on the ground. It 

 has two great divisions — the Unguiculata, or clawed 

 Quadrupeds ; and the Ungulata, or hoofed Quadrupeds. 

 In the Unguiculata there are five orders: 1. Cq,];nivora 

 {caro, flesh, voro, to devour). 2. InpecJ,iyora — Insect- 

 eaters. 3. Ro.dei\tia {rodo, to gnaw). 4. Eflentata (e, 

 •without, dens, tooth). 5.* Marsi^pialia, so called on ac- 

 count of a marsupium, or pouch in the skin, in which 

 the mother carries her young for some time after birth. 

 The division Ungulata has two orders : 1. Pachyder- 

 mata (xaxwc, pachus, thick ; Ztpfia, derma, skin), thick- 

 skinned Quadrupeds, including elephants, horses, swine 

 etc. 2. Ruminantia {rumen, a stomach or paunch), cud- 

 chewing Quadrupeds, as oxen, deer, camels, sheep, etc. 



65. The order Carnivora is divided into five families: 

 1. P^i^dse {felis, cat), the cat tribe, including cats, tigers, 

 lions, etc. 2. Capi^se (canis, a dog), including dogs, 

 wolves, foxes, etc. 3. Mus,te\i48e (rnustela, a weasel), 

 weasels, otters, etc. 4. Ursid88 {ursus, a bear), the bear 

 family, bears, raccoons, etc. 5. Phoci|Jae {<j)b>Kri, phoke, a 

 seal), seals, walruses, etc. 



66. Many of the animals which we have already no- 

 ticed have the power of living iin whole or in part upon 

 animal food, as, for example, man aftd some of the mon- 

 key tribe. But they can digest vegetable food also, and 

 can even subsist wholly upon it. Even those which live 

 on animal food alone, as some of the bats, eat insects and 

 worms, and not the flesh of the larger animals, on which
