May, 1919] Silurian Fossils From Ohio 371 



In case of the fauna listed from the Bisher member, all of 

 the fossils listed from Hillsboro, Danville, Sinking Springs, 

 Crooked Creek, Peebles, West Union and Martins came from 

 the richly fossiliferous layer occurring about 8 to 10 feet above 

 the base of this member. The fossils listed from Port Williarri 

 apparently come from about the same horizon, as far as may 

 be judged from the fossils present. Those listed from Carr's, 

 Harin Hill and Glen Springs at least belong to the Bisher 

 member. The exact location of the various exposures here 

 cited is as follows: 



Half a mile west of Port William, several hundred yards 

 south of the bridge, an exposure of the Bisher member occurs 

 in the creek. A mile southeast of Hillsboro, several hundred 

 yards northeast of Bisher dam bridge, typical exposures of 

 the Bisher member occur along the hill front, and continue at 

 various intervals as far as the deep valley southeast of the 

 built-up part of Hillsboro. About a mile north of Danville, 

 on the east side of the Hillsboro pike, is the James Sanderson 

 farm exposure mentioned by Prof. Orton. Half a mile west of 

 the southern end of Sinking Springs, the Bisher member is 

 .exposed on the western side of Baker Fork. North of Crooked 

 Creek, a mile and a half north of Locust Grove, the Bisher 

 member is exposed in a quarry west of the pike. Half a mile 

 west of Peebles, along the railroad, a large quarry exposes the 

 full thickness of this member. In the southeastern corner of 

 West Union, on the Beasley Fork road, a small roadside quarry 

 exposes the basal half of the Bisher member. The remainder 

 of the section is exposed in the open fields eastward. The 

 outcrop at Carrs is about half a mile south of the railroad 

 station, which is about 8 miles west of Vanceburg, in Kentucky. 

 The outcrop is formed by the cut of the road across the hill 

 ridge. Martins is located about 2 miles southwest of the road 

 cut. The Bisher member forms the upper part of the knob 

 northwest of the Martin store. Harin Hill is about 4 or 5 

 miles southwest of Martins; the exposure is made by the road 

 from Valley to Ribot, which cuts across the hill. Glen Springs 

 is 4 or 5 miles south of Harin Hill, on the road from Valley to 

 Esculapia Springs. Carrs, Martins, Harin Hill and Glen 

 Springs are all in Lewis county, Kentucky.

 cited from the quarry within the eastern limits of Hillsboro
