HIGHER CRUSTACEA OF NEW YORK CITY 145 



crab fishermen say that a single green crab will kill all the edible 

 crabs in a shedding car. It has been accused in England of killing 

 and eating the young oysters while their shells were thin. In 

 France, from its excitable nature, it is known as the crabbe enrage. 

 It is a favorite article of food all along the European coast.
