﻿10 GANOID FISHES OF THE CARBONIFEROUS FORMATION. 



too close a link between the other Ganoids and the living Acipenseroids to admit of the 

 separation of the latter. 



The Ganoid Fishes of the Carboniferous formation are comprised in the groups of 

 Crossopterygii, Acipenseroidei, and Acanthodei. A few fragmentary remains have also 

 been referred to Placodermi J but, so far as I am aware, there is no authentic record of 

 any member of the Lepidosteoid series occurring in strata of this age, though these 

 begin already to appear in the Permian rocks above. 



Although not coming first in order of arrangement, the Palaoniscidce will be first 

 considered in this Monograph, owing to their great interest, the comparatively small 

 modicum of attention which has hitherto been bestowed on them, and the amount of 

 ready material at present at my disposal for their description.
