THE SERGEANT-FISHES 



Family XL. Rachycentridce 



THE characters of this family are sufficiently shown in the ac- 

 companying illustration of the sergeant-fish, Rachycentron canadus. 



This fish is an inhabitant of warm seas, ranging in summer 

 as far north on our Atlantic Coast as Cape Cod. It is not un- 

 common from the Chesapeake Bay southward. It is known as 

 sergeant-fish, crab-eater, coal-fish and cobia, and it reaches a 

 length of 4 or 5 feet, and it is edible.
