OBSERVATIONS UPON THE WAYEREY GROUP. 507 



Geological Reports is so complete that a reference is all that is here requi- 

 site. Dr. Newberry has long since decided that the Bedford is Carboni- 

 ferous, basing his conclusions upon the occurrence of such fossils as 

 Syringothyris typa, Hemipronites crenistria, Chonetes logani, Orthis miche- 

 lina, and Spiriferina solidirostris. As Professor Orton states, "none of 

 these fossils have been reported south of the lake shore," and a study of 

 these localities and collections on which Dr. Newberry's opinion was- 

 founded has convinced the writer that these species do not occur in the 

 typical shaly Bedford, but in thin flags associated or iuterbedded, while the 

 t}-pical Bedford, especialty in central Ohio where it reposes directly upon 

 the "Black Shale," carries a considerable series of fossils forming a decid- 

 edly Devonian assemblage. More remarkable still, the specific resem- 

 blances are unquestionably with Hamilton (in the broad sense) rather 

 than the Chemung fauna. 



List of Fossils from the Bedford Shaee.

16. Goniatites, sp. (resembling Portage sp.) 



17. Plezirotomaria (cf. sulcomarginal a*) 



These fossils are figured on plate XX. The absence of uncon- 

 formity between the black shale and the Bed f ord, and the occasional 

 lapses into the same lithological peculiarities in the latter, permit us to> 

 assume a substantial continuity of faunae from one to the other. The 

 peculiar interblending of faunae along the border region of northern 

 Ohio is to be explained, as already indicated, by the shuffling of the sed- 

 iments of adjacent basins — a process which was continued in the Cuya- 

 hoga shale. Very careful study of the Bedford has not been rewarded 

 by any fossils south of Columbus. The most complete series of fossils 



*The species thus marked are identical with, or closely related to Hamilton-' 

 forms.
