CARTILAGINEI. PETROMYZONID^. 



It is said to be an ancient custom for the city 

 of Gloucester to present for the royal table, once 

 every year, a pie of Lampreys, covered with a 

 raised crust. King Henry I. met his death 

 through his fondness for this v^^orm-like fish ; 

 his mortal sickness having been produced by eat- 

 ing to excess of 'Lampreys, after a day spent in 

 hunting. 



There are one or two other species of the genus 

 found in our waters, but they are small, and of 

 no importance.
