Family Mugilidae. — Mullets. There are numerous species of com- 

 mon forms in the estuaries and river mouths along our southern 

 shores. (Fig. 245.) This is an esteemed food fish along Atlantic 

 coast, but it is ignored in the Gulf States. 



Family Atherinidae. — Silversides. Most of these fish are small, 

 compressed and covered with even cycloid scales. They live in 

 schools, particularly along the coast in the warmer regions.
