THE following Catalogues were prepared at the suggestion of Professor Agassiz, 

 to whose wonted liberality I am indebted for documents explanatory of his system 

 of Ichthyology, hitherto uncommunicated to the public. 



The first Catalogue contains all the Species of Fossil Fish in Lord Cole's 

 Collection and my own, arranged according to their orders and families. Their 

 stratigraphical position is shown in the eight succeeding columns, and the locality 

 whence each specimen was derived in the last. 



The second Catalogue shows the same Species arranged alphabetically. The 

 strata and localities are also annexed, together with references to the systematic 

 Catalogue, the cabinet where each species is to be found, and the figures and 

 descriptions in the Poissons Fossiles of Professor Agassiz and other publications.
