1 Very unfortunate is the destruction of the "king-crab," Limuhis, 

 which is only distantly related to the Decapoda. In Delaware Bay they 

 are caught in great numbers and ground up as fertilizer. As they are 

 taken only during the breeding season, they are being rapidly extermi- 

 nated. The American Limulus belongs to an order entirely unrepresented 

 on the European coast (Fig. 110).
