PETROM YZONID^. 



TEETH OF Petromyzon Jura. 



The Petromyzon Jura, figured in Mac Culloch's Wes- 

 tern Isles (vol. ii. pp. 186-7, t. 29, f. 1) is probably of this 

 genus. If the teeth are correctly represented, the fish 

 has no relation to Lampetra fluvialis (vide GRAY, Cat. 

 Fish, B. Mus. p. 139). It was found adhering to a 

 Gurnard on the coast of the island of Jura, one of the 

 Hebrides.
