MEASUREMENTS 



Taking the fish in the order above given, the gill rakers are: 

 9 + 17, 10 + 16, and 9 + 17. The scales are: 10-76-8, 10-87-9, and 

 11-81-10. The branchiostegals in various specimens examined 

 are 9 to 10; divided dorsal rays, 10 to 11; anal rays, 10 to 11. 



Genus ARGYROSOMUS Agassiz 



This genus is very close to Core g onus, from which it 

 differs in the larger mouth and more produced jaws, the pre- 

 maxillaries being placed nearly horizontally, and the lower jaw 

 decidedly projecting beyond them. Gill rakers very long and 

 slender, about 30 on lower limb; vertebrae 55. These characters 

 are associated with the greater voracity and, in general, greater 

 activity of the species of Argyrosomus. The species are 

 numerous in the northern parts of Europe, Asia and North 

 America, and all are valued as food.
