240 MYTILUS. MUSSEL. Class VI. 



Inhabits fresh waters. 



Crows feed on these mussels; and also on 

 different shell-fish. It is diverting to observe, 

 that when the shell is too hard for their bills, 

 they will fly with it to a great height, drop the 

 shell on a rock, and pick out the meat, when the 

 shell is fractured by the fall. Tab. lxxi.
