526 VERTEBRATE FAUNA OF LAKELAND 



LAMPERN. 



Petromyzon Jluviatilis, L. 



The river Lamprey is common in the Petteril and some 



other tributaries of the Eden, the Caldew for example. The 



Keswick Museum possesses a local specimen, procured by the 

 late Captain Kinsey Dover. 



PRIDE. 



Petromyzon branchialis, L. 



Richardson records this species as ' frequent in the Eamont, 

 and is about five inches long. There called Lamper eel.' Dr. 

 Heysham writes of this species and the last, ' Neither of these 

 species are very plentiful in our rivers. They appear and dis- 

 appear about the same time as the Lamprey.' It is quite true 

 that these species are seldom caught, but I fancy that it is more 

 because no one searches for them than because they are actually 

 rare. This species, like the last, is to be found in the Petteril 

 near Carlisle.
