RISE AND PROGRESS OF ZOOLOGY. IxXVli 



Cervus, Moschus. Ninth, Belluce, six genera : 

 Sus, Tapir, Elephas, Rhinoceros, Hippopo- 

 tamus, Trichecus. The tenth and last, Ce- 

 tacea, four genera : Monodon, Balaena, Phy- 

 seter, Delphinus. Such is M. Blumenbach's 

 arrangement of the Mammalia. 



It may not be out of place to notice here 

 that our author, in his original distribution of 

 animals in his Tableau Elementaire, varied a 

 little from the arrangement of the Regne Ani- 

 mal — He distributed the class Mammalia into 

 three grand divisions : — 



I. — Those which have claws or nails, in- 

 cluding the following orders : — Bimana, Qua- 

 drumana, Cheiroptera, Plantigrada, Carnivora, 

 Pedimana, Rodentia, Edentata, Tardigrada. 



II. — Those which have hoofs. Pachyder- 

 mia ata, Ruminantia, and Solipeda. 



III. — Those which have extremities adapted 

 for swimming. Amphibia and Getacea. 



M. Illiger commences his synopsis of the 

 Mammalia, by definitions of the zoographical 

 terms, which will be found extremely useful to 

 the student. He divides the Mammalia into 

 orders, families, genera, species. The orders 

 are fourteen.
