6 Mam. Classifica Hon . 



under the order Pacliydermata the following three genera, 

 viz. Proboscidea, Ordinaria {e.g. Sus and Tapirus), and Solid- 

 ungula. 



Modern classification has raised Cuvier's genus P. Probos- 

 cedia to rank as an Order, and has subdivided his genus P. 

 Ordinaria into three ; first, taking out those animals with an 

 "Even" number of digits fully developed ; and, secondly, 

 taking out of the remainder, which of course have an " Odd" 

 number of fully developed digits, the Hyracidae. With the 

 " Even" toed P. Ordinaria has been associated Cuvier's Rumi- 

 nantia, to form the Order called Artiodactyla (apnog even, 

 ^aKTvXog digit). With his " Odd" toed P. Ordinaria has been 

 grouped Cuvier's Solidungula, to form the Order called 

 Perissodactyla (Trepiaraog odd, uneven, daKrvXog, digit). Lastly, 

 the family of the Hyracidae has been elevated to form the 

 Order called Hyracoidea.

YII. The PROBOSCIDIA. The members composing this 

 Order are characterised by the possession of two incisors, in 

 the form of long tusks ; and of a nose prolonged into a cylin- 

 drical trunk, flexible in all directions, highly sensitive, and 

 terminated by a prehensile appendage like a finger. Herein 

 are included 



only the Family 

 of the Elephantid(2. 



YIIL In the Order PERISSODACTYLA are included aU 

 those animals that have an unsymmetrical or odd number 

 of toes in the hind feet always, and generally in the fore 

 feet also. In the Tapiridae, however, the fore feet are "even"
