This fish, so remarkable for its bizarre figure and lustrous tints, is more common on our 

 coast than any of the four preceding species. A native of the tropical seas, its geographical 

 range is so great as almost to entitle it to be considered a cosmopolite. It is found on both 

 sides of the Atlantic, and even in the Pacific on the coast of Peru. New- York is probably 

 the limit of its northern range on this side of the Atlantic. It is esteemed for food, and 

 appears in our waters in July and August. It is found occasionally one foot long.
