5i6 The Ohio Naturalist. [Vol. IX, No. 7, 



Knob, seven miles south of Louisville, Kentucky, were closely 

 related to the upper Kinderhook, as exposed in the Mississippi 

 Valley. Since these layers at the Button Mold Knob belong to 

 the strata known in Indiana as the New Providence shales, and 

 since the equivalent of these strata lies at the base of the Cuya- 

 hoga section in east-central Kentucky, it is probable that those 

 parts of the Waverly which underlie the Cuyahoga also are 

 approximately equivalent to various parts of the Kinderhook 

 section in the Mississippi Valley. From this standpoint, the 

 Bedford may be regarded for the present as a lower Kinderhook 

 horizon. 



During the summer of 1908, Mr. W. C. Morse and the present 

 writer were engaged, under the auspices of the Kentucky geolog- 

 ical survey, in tracing the lower Waverly formations southward 

 from the Ohio River. In the course of these investigations it 

 became evident that even in the first county south of the river, 

 Lewis County, the Berea lost its distinguishing feature as a series 

 of distinct sandstones, strongly ripple marked, and no longer 

 could be readily distinguished from the underlying Bedford. 



For the attenuated part of the Bedford and Berea section, the 

 term Bedford-Berea is employed temporarily. 



In the east-central part of Kentucky, at Indian Fields and 

 Irvine, where the Bedford-Berea section does not exceed one 

 foot in thickness, a number of fossils have been found, and since 

 very little is known, so far, of the paleontology of the Bedford- 

 Berea section either in Ohio or Kentucky, the following notes are 

 here appended. 



In the fourth volume of the Bulletin of Denison University, 

 in 1888, Prof. C. L. Herrick identified from the Bedford clay 

 shales at Central College, Ohio, the following species: 



Lingula melie. 



Orb icu lo idea n en 'berry i . 



Palaeoneilo bedfordensis. 



Leda { = Nuculana) diversa-bedjordensis, var. nov. 



Orthis ( = Rhipidomella) vanuxemi. 



Chonetes scitulus. 



Ambocoelia umbonata. 



Macrodon hamiltoniae. 



Microdon { = Cypricardella) bellistriatus . 



Bellerophon neivberryi or helena. 



Loxone-yna cf. delphicola. 



Orthoceras cf. linteum. 



Pleurotoniaria sulcomarginata. 



Goniatites cf. Portage species. 



Heniipronites { = Schuchertella) sp. 



Pterinopecten sp. 



Bellerophon lincata.
