THIS species, when adult, is easily distinguished from the 

 Lampern last described, by its being much shorter in length, 

 and yet equally thick in substance : it may also be recog- 

 nised at all ages, on comparison with it, by its having the 

 whole broad edge of the circular lip furnished with numerous 

 papilla forming a thickly-set fringe, and by the depth and 

 close connexion of the two dorsal fins. 



Dr. Parnell says, this species is found in the Forth, the 

 Teeth, the Allan, and several other rivers in Scotland. I 

 am indebted to the kindness of Sir William Jardine for two 

 specimens of the young of this species, which were sent 

 from the Tweed. Dr. Johnston has been told that it is 

 not uncommon at Melrose. I have received some from 

 Surrey, and Mr. Linwood mentions having found some in 

 Sussex. Mr. Couch has obtained specimens from a branch 

 of the Looc, in Cornwall. I have received some specimens
