ICHTHYOLOGY. 



FIRST GREAT SERIES OF THE CLASS OF FISHES. 



ORDINARY OR OSSEOUS FISHES. 

 ORDER I.— ACANTHOPTERYGII. 



These, as already mentioned, form much the most nu- 

 merous division of the class. They are distinguished by 

 the spines, which occupy tlie place of the first rays of the 

 dorsal fin, or which alone sustain the anterior dorsal when 

 there are two. Sometimes, instead of an anterior dorsal, 

 there are only a few free spines. The first rays of their 

 anal fin are also spinous, and there is generally one of a 

 similar nature to each of the ventrals. The Acanthoptery- 



Percijit. 



gians bear so many relations to each other, — their several Acanlhop- 

 natural families exhibit so many variations in the apparent J'^O'Su. 

 characters which one might suppose capable of indicatina 

 orders or other subdivisions, — that it has been found im- 

 possible to divide them, otherwise than by those natural 

 families themselves, which are thus left without any higher 

 combinations. 



FAMILY I.— PERCID.^. 



So named because well typified by the common perch. 

 Their bodies are of an oblong form, covered with scales, 

 which are generally hard and rough ; the opercle andpre- 

 opercle, and frequently both, have the margins toothed or
