THE CCELACANTHINI. 7 



of Coelacanthines belonging to the genera Ccelacanthus and Macro- 

 poma, without finding any reason to modify the definitions just 

 given ; but the materials which have passed through my hands 

 enable me to illustrate the structure of these genera more fully 

 than has hitherto been possible. 



I commence these illustrations with the genus Ccelacanthus, 

 for the opportunity of examining numerous specimens of which 

 I am indebted to the Earl of Enniskillen, Sir Philip Grey 

 Egerton, Bart., Dr. Rankine, of Carluke, Edward Binney, Esq., 

 F.R.S, of Manchester, Dr. Garner, and Messrs.Molyneux, Ward, 

 and "\Yeston.
