Remarks. — Abundant on the New Jersey coast, and elsewhere 

 very widely distributed, ranging along the Atlantic coast of 

 North America from the Gulf of St. Lawrence to North Caro- 

 lina, Bermuda, Barbadoes and South America. It also occurs in 

 many regions of the Old World, if all the described forms are 

 synonyms. Its known bathymetric range is from the surface to 

 a depth of one hundred and nineteen fathoms. It lives on the 

 surface of the sea among floating objects, as grass, seaweed, 

 etc., and among eel-grass and algae. Along the seashore it occurs 

 in gravel and sand. It forms the food of some fishes, having 

 been taken from the stomach of the smelt (Osmerus epcrlanus).
