Letham, Ohio. Wednesday Sep 20. Collecting in the stream just north of the turn. In the first high bank about ten feet above the stream occur the R. fraeta beds a [illegible] lot (1). Also saw Byssonychia radiata, Heterinea demissa, C. senara, O. media, R. alternata paeta, in the association there is a bed of Ardiolypus, Byssonychia and Orthoceros. All is telur away R. lynx; loose specimens are here rolled down from above. In going up the stream through these 10 feet and perhaps 7 feet more one comes upon beds made up of R. paeta and not get typical R. ponderosa. Almost nothing else occurs with them, and in places they are matted together in mains ons by the shallow sea... Then for higher R. lynx begin to appear along with R. ponderosa and then all other forms are almost about gone or very preserved and not so common as the unrecognizate. G. modesta also to Germania, Hardy an O. sinuata. Bysozon are also rare. The same Orthoceros is here. Have two large Byssonychia with very coarse flieations. All of these are from a zone not more 4 feet thick. Lot (2) has rails from these spots and the 7 foot telur.
