A HISTORY OF NOTTINGHAMSHIRE 

 CYCLOSTOMES 



29. Lamprey. Petromyzon mannus, Linn. 



Occurs in the Trent, but not commonly ; 

 a fine specimen caught in the river at Fisker- 

 ton about 1897 is now in the Nottingham 

 Museum. 



30. Lampern. Petromyzon fluviatllh, Linn. 



Abundant in the Trent, especially about 

 Colwick, Beeston, Newark and Averham 

 Weirs where great quantities used to be taken 

 and sent to Grimsby for bait for sea-fishing. 

 I have seen it in considerable numbers in the 

 Rainworth Water near Mansfield.
