,, The space (2 D-3 D) is equal 



to half the base of the 



second dorsal pollachius, argenteus. 



„ The space (2 D-3 D) is equal 



to about three-eights of the

 „ The space (2 D-3 D) is equal 



to one-third or one-fourth 



of the base of the second 



dorsal ogac, merlangus, pollachius, esmarki, 



argenteus, saida. 

 ,, The space (2 D-3 D) is equal

the second dorsal fin seglefinus, merlangus, virens, pol- 

 lachius, esmarki, saida, ogac. 

 „ The space (2 D-3 D) is less 



than one-fifth of the base of 



the second dorsal fin callarias, seglefinus, merlangus, virens, 



pollachius, luscus, minutus, esmarki. 



XI. Anal Fins : —

pollachius (adult), argenteus, saida, 

 navaga. 



d. The first anal fin ends in a rounded extremity in callarias, ogac,
