toral fin saida. 



b. ventral fin equal to pectoral 



fin seglefinus, luscus, minutus. 



c. ventral fin less than pectoral 



fin 



„ ventral fin greater than half 

 (•7-9) the length of the 



pectoral fin callarias, ogac, seglefinus, merlangus, 



luscus, minutus, navaga, esmarki. 



„ ventral fin about half ('4--6) 



of the pectoral fin ... , merlangus, virens, pollachius, 



esmarki, poutassou. 



ventral fin less than half the 



pectoral fin pollachius, poutassou. 



VIII. Lengths of the Pectoral and First Dorsal Fins : — 



a. first dorsal distinctly greater 



than the pectoral '..callarias, ogac, seglefinus, argenteus, 



pollachius 



b. first dorsal equal or about 



equal to the pectoral merlangus, virens, luscus, minutus, 



pollachius, navaga (?). 



c. distinctly less than the pec- 



toral poutassou, saida, esmarki. 



IX. The Position of the First Dorsal Fin : — 



a. The beginning of the first 



dorsal fin is just in front of 



the base of the pectoral fin. ..seglefinus. 



b. The beginning of first dorsal 



coincides with the base of 



the pectoral fin seglefinus, esmarki. 



c. The first dorsal begins close 



behind the base of the 



pectoral callarias, seglefinus, merlangus, luscus, 



minutus, esmarki, argenteus. 



d. The distance between the pec- 



toral and first dorsal fins is 

 greater than the length of 



the snout virens, pollachius, poutassou.

 pectoral and first dorsal fins 

 is equal to the length of the 



snout virens, pollachius, poutassou, minutus, 



esmarki, saida, navaga.
