relationship with any of the others, being chiefly distinguished 

 by negative characters. This is the order Edentata, com- 

 prising the Sloths, the Armadillos and Ant-eaters of America, 

 and the Pangolins and Orycteropus or Cape Ant-eater, of the 

 Old World. These are animals of generally low organiza- 



|»n for the division to which they belong. 

 The remaining Monodelphian Mammals are : — 1. 

 umates, the highest order, culminating in the genus 

 01110 of Linnaeus, and comprising also all the animals 

 commonly known as Monkeys. With these are generally 

 united a group of very inferior structure (Lemurina), con- 

 taining the various species of Lemurs and allied animals, 

 which, without question, connect the Primates on the one 

 hand with the Insectivora, Carnivora, and Chiroptera on 

 the other ; though it is doubtful, at present, whether they 

 should be associated with the Monkeys, or -should con- 

 stitute a distinct order by themselves. 2. Chiroptera, or 

 Bats. 3. Insectivora, or Hedgehogs, Shrews, Moles, &c. 



4. Carnivora, divided into the Terrestrial Carnivora, or 

 Fissipedia, Cats, Dogs, and Bears, and the various modifi- 

 cations of these types ; and the Aquatic Carnivora, or 

 Pimiipedia, Seals, Walrus, and Eared Seals, or Sea Lions. 



5. Cetacea, containing two sub-orders, the Mystacoceti, 

 or Whalebone Whales, and the Odontcceti, Cachalots, 

 Narwhals, Dolphins, and Porpoises. 6. Sikenia, a small 

 order of aquatic vegetable-feeding animals, of which the 

 Manati (Manatus) and Dugong (Halicore) are the sole 

 living representatives. 7. Ungulata, the very large order 

 of hoofed quadrupeds, divided into the Perissodactyla, or 

 " odd-toed " Ungulates, containing the Horse, Tapir, and 

 Rhinoceros; and the Artiodactyla, or " even- toed," again 

 subdivided into four sections, a. The non-ruminating, or 

 Suiiia, consisting of the Pigs, Peccaris, and Hippopotamus.
