Shales of the Lower Ovislay appear. In these beds I saw Leptocidii Helellites, L. finihista, Orthothelis (on specimen) and the new species described by me. The second one is probably also A. Grill. The erosion of the Heldburyian beneath the Lower Ovislay is decidedly different between here and Cast Valley. At D.B.B. only 10 feet of the New Red Sandstone is left. At Conijansville about 1/2 the same amount is present. At Cast Valley all of the Heldburyian is gone as the Lower Ovislay only then rests on the Marluries. Out of the sun cracked layer 3C Beds due out Atrypa reticularis, Aspidula galeata a new species (sick). These were in a rolled mass as I drilled into the limestone, i.e. rolled mud ball. It is difficult to understand the various sun- cracked deposits of a limestone nature in the Affek- bachians of a marine nature. We see them almost in all the formations and especially in the magnesian deposits. Certain it is that all the limestones seen are of very shallow origin for one sees these sun cracked limestones (usually in some) emerging into normal marine deposits reflect onto frosts.
