14. It will be necessary now to point out wherein the 

 terms Anguillida, Murcenidce, and Synbranchida as here 

 used, imply a different meaning from the sense in which 

 they are employed by Mr. Swainson in his work on the classifi- 

 cation of Fishes. The arrangement proposed by this author, 

 differs from that of Linnaeus in omitting the jugular and 

 thoracic orders, and introducing cartilaginous and semi- 

 cartilaginous fishes as two distinct orders in their place, 

 thus making the spinous fishes the first, and the soft-finned 

 the second order, placing Apodal fishes last. The Apodal 

 fishes he disposes as follows : —
