*"P. fluvialis, Richardson, mentioned only as a small lamprey attached to an Inconnu in Great Slave Lake." 

 Jordan and Evermann. "The proper identification of the specimen is uncertain; it is probably the same as L. 

 aurea." Evermann and Goldsborough. 



+"I am not positive as to the occurrence of this species in our waters, though I have often taken a small 

 Lamprey in the northern and western streams of Ontario and in the rivers of Manitoba which I believe to be the 

 Brook Lamprey." Nash. 



{At the time of the publication of Jordan and Evermann's 'Fishes of North and Middle America' (1896) only 

 one specimen of this species was. known, "a female with mature eggs."
