This part of the fyftem, taking in a few fpecies 

 defcribed in the appendiic of the third Tome, and 

 in the Mantiffa of 1771, contains about 230 fpecies. 

 Mr. Pennant^ in his Synopfts of ^adrupeds^ and our 

 learned friend Profejfor Martin, in his Elements of 

 Natural Hijiory^ by including fome animals that 

 were unknown to LiNNi^:us, and giving the rank 

 of fpecies to feveral that were confidered by our 

 author as varieties, have extended the number of 

 Mammalia to 289 fpecies.
