One-half mile west of Graveyard Hill (between Oak Hill and 

 Palmer's mill) the following species were collected from beds 

 evidently of the same horizon as those seen i mile north of 

 Allenton: Encliniaioceras ulrichi, Ostrea pulaskensis, Nucula me- 

 diavia, Cucidlcsa viacrodo7ita, Venerica7'dia alticostata , Yoldia eborea, 

 Crassatella sepulcollis, Pedunailus, Tornatellcea quejxollis, Pleuro- 

 toma adeona^ Olivella mediavia, Tuj'ritella alabamiensis , Mesalia 

 alabaniiensis, Pyrula Juvenis, Pseudoliva scalina, Volutilithes ru- 

 gatus, Natica perspeda, Calyptrophojnts velaius var. 



The ' ' hard ledge' ' around the upper portion of Graveyard hill 

 contains numerous fragmentary specimens of a Meretrix, Veneri- 

 cardia alticostata, and a Cephalopod probably E. ulridii. 



Troy and vidnity. — Our stay in this region was unfortunately 

 very brief and we were unable to obtain any satisfactory sections, 

 exposures or collections. In the road, however, about 3 miles 

 east-southeast of Troy imperfect specimens were obtained of what 

 appeared to be Ostrea crenulhnarginata and Venericardia alticoS' 

 tata in a red iron clay-stone. 



Clayton and vid?iity. — There are several important exposures 

 in the vicinity of Clayton, Barbour Co., that furnish a well 

 characterized fauna. On the railroad northeast of here about 

 I mile a deep cut is seen exposing blue clays above and ledges of 

 light sandy limestone below with many specimens of Ostrea cremi- 

 limarginata. One- third mile farther on, another cut is found 

 exposing the following beds: — 



a. Dark clay, unfossiliferous as far as observed but 



containing perhaps some tripoli. Seen in the 



upper part of cut, - - - - 20 feet. 



b. lyignitic clay; dark, - - - - 3 feet. 



c. Light yellowish, impure, arenaceous limestone, 



with innumerable casts and impressions of Ttir- 

 ritellcB and other forms. According to Dr. Gill 

 a specimen of this contains over 45 per cent, of 

 quartz sand, with a little mica and limonite, 4-8 feet. 



d. Yellow sand. This bed extends from the level of 



the R. R. track up to the hard limestone ledge 



(c). Barren, - - - - 8 feet. 



e. L/ignitic clay, more or less micaceous and pebbly, 



separated from the bed below (/) by a line of 

 nonconformability. This is seen only at the 

 east end of the cut, - - - 2 feet. 



/, Blue micaceous, clayey sand. Seen below the R. 

 R. track near the east end of the cut. Nonfos-
