X. The Second and Third Dorsal Fjns : — 



a. united luscus (sometimes). 



b. meet without uniting luscus, minutua. 



'•. The space hetween the second 



and third dorsal fins is 



equal to, or greater than, 



the length of the base of 



the second dorsal fin poutassou. 



„ The space (2 D-3 D) is equal 



to four-fifths the base of 



the second dorsal fin poutassou. 



„ 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 



base of the second dorsal... navaga. 

 „ The space (2 D-3 D) is equal 



to one-third or one-fourth 



of the base of the second 



dorsal °g ac j merlangus, pollachius, esmarki, 



argenteus, saida. 

 „ The space (2 D-3 D) is equal 



to one-fifth of the base of 



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, a?glefinus, merlangus, virens, 



pollachius, luscus, minutus, esmarki. 



XL Anal Fins : — 



a. united luscus, merlangus (sometimes). 



b. First anal has a long base — 



reaches to second anal with- 

 out uniting merlangus, minutus, esmarki, poutas- 

 sou (pollachius, in some the first 

 anal just fails to reach the second 

 anal). 



c. There is a gap between the 



first and second anal fins...callarias, ogac, seglefinus, virens, 



pollachius (adult), argenteus, saida, 

 navaga. 

 <h The first anal fin ends in a rounded extremity in callarias, ogac, 

 merlangus, pollachius, poutassou. It tapers away to nothing 

 in virens. They vary a little in different fishes. 



XII. Girth:— 



a. Girth at pectoral region greater 



than the girth at anus callarias, seglefinus, merlangus, pout- 

 assou, argenteus, saida. 



b. Girth at pectoral region equal 



to the girth at anus ceglefinus, merlangus, poutassou, 



argenteus.
