Taking the fish iu 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 

 ditfers 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, iu general, greater 

 activity of the species of A r g y r o s o m u s . The species are 

 numerous iu the northern parts of Europe, Asia and North 

 Amcricii. and all are valued as food.
