Viscount d'ARCHiAC and M. de Verneuil's 



Note. — We are indebted to the kindness of Sir Philip Grey Egerton for this list of the Devonian fishes, which, including some species named 

 by Agassiz, in the splendid collection of that distinguished geologist, and not yet published, is necessarily more complete than the one 

 we had prepared. It is the best for the present time, though it does not perhaps contain all the species named by Agassiz in his last 

 visit to Scotland, Sir Philip Grey Egerton not having had the opportunity of examining the Scotch collections since that time.
