142 NOTES ON BEl'TILBS, AMPHIBIA, AND FISIT. 



18 rotromyzon marinus, the Sea Lamprey. Ascends the 

 Severn in large numbers in April and May. I have never 

 heard of its being found in the Avon. _ 



19 Fetromyzon fluviafAUs, the River Lamprey. ii'is 

 species is common in the Severn, and is indigenous. 



20. Flaiessaflesus, tlve Flounder. Is abundant in the Avon 

 and Chew. Colonel Montagu recorded its occurrence ux the 

 Avon as high as within three miles of Bath. 



In conclusion, I very much regret that I have been unable 

 to make these notes more complete. I think it is a pity 

 that whilst the insects, the shells, the plants, down to the 

 humblest fungi, have found such able exponents amongst us, 

 the reptiles and fish have so far been completely neglected. 

 There exists a common prejudice against the former class, 

 which however would disappear on investigation of their 

 strocture and habits, and there are many most mterestmg 

 points in their life history on which our books are either 

 silent or vouchsafe but doubtful information. May these 

 incomplete notes induce some member who has more 

 leisure to take up these branches of our vertebrate fauna, 

 and to thoroughly work them out.
