PACHYDERMATA. 99 



FAMILY II. 

 PACHYDERMATA ORDINARIA, 



Or the Ordinary Pachydermata, have four, three, or two toes. 



Those in which the toes make even numbers have feet somewhat cleft, and 

 approximate to the Ruminantia in various parts of the skeleton, and even 

 in the complication of the stomach. They are usually divided into two 

 genera. 



HIPPOPOTAMUS, Linnceus. 



These animals have a very massive and naked body ; very short legs ; the 

 belly reaching to the ground ; an enormous head terminated by a large in- 

 flated muzzle, which encloses the apparatus of their large front teeth ; the tail 

 short ; the ears and eyes small. They live in rivers, upon roots and other 

 vegetable substances, and exhibit much ferocity and stupidity. One species 

 only is known. 



H. amphibius. (The Hippopotamus.) Now confined to the rivers of the 

 middle and south of Africa. 



Sus, Linncens. 



Hogs, properly so called, have twenty-four or twenty-eight grinders, of 

 which the posterior are oblong with tuberculous crowns, and the anterior more 

 or less compressed, and six incisors in each jaw. 



S. scrofa, Lin. The Wild Hog, which is the parent stock of our Domestic 

 Hog and its varieties, has prismatic tusks that curve outwards and slightly 

 upwards ; the body short and thick ; straight ears 5 the hair bristled and black ; 

 the young ones striped black and white. It does great injury to fields in the 

 vicinity of forests, by tearing up the ground in search of roots. Naturalists 

 now separate from the Hogs the subgenera Phacochcerus, and Dicotyle or the 

 Peccaries. 



Here may come a genus now unknown in the living creation, which we 

 have discovered, and named 



ANOPLOTH E RIUM. 



It presents the most singular affinities with the various tribes of the Pachy- 

 dermata, and approximates in some respects to the order of the Ruminantia. 



The bones of this genus have hitherto only been found in the gypsum 

 quarries near Paris. We have already ascertained five species. 



RIIINOCEOS, Linnaeus. 

 The ordinary Pachydermata which have not cloven feet comprehend, in the
