L. — A Contribution to the History of the Carboniferous 

 Ganoid^ Benedenius deneensis, Traquair, with Notes on 

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

 F.R.S. 



[Plates IX. & X.] 



TuANKS to the kindness of ray friend the Rev. Dora 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 Palceoniscus by the 

 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. Fraipont. 



These specimens were obtained from the black marble 

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

 have lately yielded two further specimens of the fish, which 

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

 beautiful abbey of Maredsous, near Dei>^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, 

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