brown, mottled and spotted on the back and sides with 

 darker green and dark brown ; the margins of the fins in- 

 clining to reddish brown ; the irides golden yellow. 



In slowly-running water, the Lamprey swims with a lateral 

 undulating motion of the body, assisted by its fins : where 

 the current is rapid, it makes successive plunges forward, 

 attaching itself quickly to any fixed substance that offers to 

 secure the advantage gained. 



The figure of the fish at the head of this subject was taken 

 from an excellent drawing made by Mrs. Ley. 



Pennant states that it has been an old custom for the city 

 of Gloucester annually to present his Majesty with a Lam- 

 prey pie, covered with a large raised crust.
