The clafs of Fifhes contains about 400 fpecies, 

 but very great additions have been made to this 

 clafs by later difcoverics : among which thofe 

 made by Dr. Forjkaly in Arabia^ are not the leaftj 

 as appears by his fragments lately publiftied. 



Great pains were taken by Artediy and fince 

 by GronoviuSy and our author, to diftinguifli 

 the fpecies by the number of the rays in the fins ; 

 and although, from repeated obfervations, they 

 are found to agree in many fpecies very re- 

 markably ; yet, in others, they vary fo much 

 as not to eftablifh a fufficient charafter. At 

 prefent, in this fyflem, the fpecifical charafters 

 are taken from a great variety of particulars ; 

 amongft which, however, the number of the rays in 

 the fins is frequently the moil diftindive, and whe- 

 ther fo or not, it is fubjoined to moft fpecies, and 

 ufually, as they have been obferved by different 

 authors. The form of the taily the cirriy or beard
