This species differs from the preceding one in its body 

 having more depth, its back a greater elevation, and its 

 proportions much stronger in body, fins and scales. The 

 adipose fin, which is broad, appears to consist of delicate 

 rays, much pressed, and in pairs.

Second Family, or that of the HERRINGS.

 with scales. All possess a natatory bladder, and for the 

 most part numerous cascas. Some ascend the rivers.
