Dear Sir, 



P E A R C H. 



PERCA; of the genus of thoradd. Th6 

 diftinguifhing characters are, the bran- 

 chioflege membrane contains feven bones, 

 and the ventral fins placed under the 

 pe&oral: 



The pearch is a delicate eating fifh, 

 moftly bred in pools, but often found 

 in the deep parts of large rivers ; hog- 

 backed, on which are placed two fins, 

 the rays of the dorfal are very ftrong 

 and fharp. Notwithstanding the defence 

 this formidable weapon may enable them 

 to make, the pike will as eagerly take 

 thsm as any other fmall fifh. The poflo 

 rior fin is extremely foft and* flexible, 

 the peftoral and ventral fins red ; they 

 h^ve five dark {hades that crofs their 

 B backs
