Rhadinichthys devonicus? (Clarke) 



(PI. 65, figs. I, 3) 



Several isolated plates in the collection, from the Cleveland shales 

 of Ohio, bear an ornamentation very similar to that of plates of 

 Rhadinichthys devonicus from the Portage of Western New York, an4 

 it appears probable that they belong to the same species. They are 

 of about the same size as the latter, and so far as can be made out from 

 their imperfect preservation, they have the same outlines as the cor- 

 responding plates of the Western New York form. In Plate 65, figure 

 I, a maxilla from the Cleveland shale is shown, for comparison, near 

 a maxilla of Rhadinichthys devonicus ( E 2066) from the Portage near 

 Buffalo. 



E 2565 A right maxilla, on a piece of shale, displaying ornamenta- 

 tion and greater part of outline of the element. (PL 65, 

 fig. i). 



Cleveland shale (Upper Devonic); Linndale, near 

 Cleveland, Ohio. Collected by W. L. Bryant. 



E 2566 Both mandibles, separated from each other, and displaying 

 the outer, ornamented surface. Teeth are to be seen 

 in both mandibles, but cannot be clearly made out. 

 (PL 65, fig. 3.)
