816 E. O. ULRICH CORRELATIONS OF CHESTER FORMATIONS 



renamed Bethel by Butts. A visit to this locality in the summer of 1918 by 

 the writer in company with Mr. Charles Butts established the fact that the 

 Rosiclare sandstone had been mistakenly identified and mapped as Cypress 

 by Ulrich, and that consequently these Sainte Genevieve limestone species 

 were actually collected from the Fredonia limestone instead of from the 

 'Upper Ohara.' " 



Xow there are two features about this quoted statement by Weller that 

 need attention. In the first place, I have always mentioned, in speaking 

 of this fauna found by me near Levias and also published on page 15 7 

 of the Kentucky Report, that the Platycrinus occurred at this place in 

 the same layer of shaly rock with several species, among them the coral 

 Amplexus geniculates, that are known to occur only in the Upper Ohara 

 or in higher positions. Regarding this coral, Weller thinks so well of it 

 as a guide fossil that he uses its name in giving a faunal designation to 

 the Ohara zone in w r hich it is commonly found. But why, I may justly 

 ask, does he omit all mention of Amplexus geniculatus in this and other 

 attempts to discredit my statements as to the local presence in the Upper 

 Ohara of western Kentucky of Platycrinus penicillus or hutitsvillce, as it 

 was called by Wachsmuth and Springer and myself? And why, again, 

 does he ignore the statement made by me at the same time that I col- 

 lected this Platycrinus "above the conglomeratic bed at Cedar Hill, near 

 Princeton" — the type locality of the Ohara — wliere he knows very well 

 there is no possible chance of confusing the Rosiclare and Bethel sand- 

 stones ? Let us consider all of the evidence and not only that part which 

 is regarded as favoring particular views. 



The second feature concerns the asserted establishment of the fact that 

 I had mistaken the Rosiclare sandstone for the Bethel. That I should 

 have done so seemed to me not only highly improbable, but almost im- 

 possible. The two beds, as a rule, are so very unlike. To make sure of 

 this, Mr. Butts and I visited the locality near Levias in June, 1921. A 

 mineralized fracture with small displacement of beds runs lengthwise 

 through the valley. The downthrow is on the east side of the vein. On 

 the west side, which I had not previously visited, the area having been 

 mapped by an assistant, we found and immediately recognized the Rosi- 

 clare sandstone and under it the Fredonia, with its usual characteristics. 

 But this was not the place where I had found the fossils. After a brief 

 search I recognized the spot on the east side of the vein, in the slope of 

 the hill that is capped by the Bethel sandstone to a near-by larger fault. 

 Approximately 50 feet beneath the Bethel and fully 30 feet above the 

 Rosiclare we found the shaly bed from which the fossils in question were 

 collected in 1903, on the occasion of a very hurried visit to a prospect a
