laceous shales and thin brownisli-red sandstones. Fossils are not abund- 

 ant, being found only in the thicker layers. This exposure is in the 

 upper part of the Chemung stage. The dip is N. W., and it is on. the 

 western side of the anticlinal fold. At the side of the road are loose 

 stones from Mr. T. L. Layman's farm, mainly sandstones a few of which 

 are somewhat calcareous and these contain in certain layers numerous 

 fossils. On weathering the blocks are quite yellowish-brown from the 

 small amount of iron they contain. Among the fossils are Douvillina 

 arcuata Hall, Chonetes scitulus Hall, Dictijophyton, a large number of 

 pelecypods and Loxonema tcrebrum Hall. 



On top of a hill just east of Mr. Layman's and about 7I/2 miles east of 

 Grantsville buff shales occur and thin sandstones in which are a few 

 fossils ; but the fossils are rare and do not form layers in the rock. Near 

 the top of the hill are shales varying from brownish-red, argillaceous to 

 those that are thin and arenaceous. The dip is 2° to tlie east. Both 

 these zones are between the sixth and seventh mile posts west of 

 Frostburg. 



From the collections made on the National Eoad 6 miles west of 

 Frostburg, Dr. J. M. Clarke has reported the following species: Chonetes 

 scitulus Hall, SchucUertella chemungensis (Conrad), Spirifer disjunctus 

 Sowerby. Reported from 5 to 7 miles west of Frostburg : Atrypa hystrix 

 Hall, Actinopteria cf. epsilon Hall, Lepiodesma liclias Hall, Lcptodesma 

 lonffispiniim Hall, Lyriopccteri tricostatus (Vanuxem), Orthonychia pros- 

 seri Clarke, Turbo coronula Clarke. From a few miles west of Frostburg 

 were listed : Cypricardella sp., Cypricardella nitidula Clarke. In addition 

 the following species were reported but without statement as to the distance 

 west of Frostburg at which they were found : Atrypa reticularis (Linne), 

 Douvillina cayuta Hall, Douvillina cayuta, var. graciliora Clarke. 



Near the top of the first hill east of the sixth mile post west of 

 Frostburg the rocks are mainly olive, very argillaceous shales. There is 

 an occasional sandy layer in which are pelecypods. One of these 

 blocks shows ripple marks very nicely ; while the shales where they 

 were dug out for the road are nearly horizontal. Directly over the 

 summit of the hill, on the eastern side, the rocks in place are mostly
