L. — A Contribution to the History of tJie Carboniferous 

 Ganoid.^ Henedenias deneensis, Traquair, with Xotes on 

 Two newly-discovered Specimens. By G. A. BOULENQEE, 

 F.R.S. 



[Plates IX. & X.] 



Thanks to the kindness of my tViend the Rev. Dom Gr^goire 

 Fournier, O.S.B., I am able to make some additions to our 

 knowledge of an imperfectly characterized Lower Carbon- 

 iferous Fish allied to Eurynotus, previously known from two 

 specimens only — the original, preserved in the University 

 Museum of Louvain, first described as a Falceoniscus by tiie 

 late Prof. Van Beneden and later as the type of a distinct 

 genus, Benedenius deneensis, by Prof. Traquair ; the second, 

 preserved in the University Museum of Lidge, described as 

 Benedenius Soreili by Prof. Fraipout. 



These specimens were obtained from the black marble 

 quarries of Denee, Prov. Namur, Belgium. The same quarries 

 have lately yielded two turther specimens of the fish, which 

 are deposited, under the care of Father Fournier, in the 

 beautitul abbey of Maredsous, near Den^e, where I had an 

 opportunity of seeing them on a recent visit. Having been 

 so fortunate as to obtain the loan of these valuable fossils, 

 1 propose to give an account of them, and thus to supplement
