Genus argvrosomis Agassiz 



This genus is very close to Coregonus, from which it 

 differs in the larger mouth and more produced jaws, the i)re- 

 maxillaries being placed nearh' 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 



t 



activity of the species of A r g 3' r o s o m u s . The species are 

 numerous in the northern parts of Europe, Asia and North 

 America, and all are valued as food.
