Belongs to the type of R, wilsoni and is one of the forms often re- ferred to that species. In some of its variations it resembles E. pyramidata ; and sometimes still more R, nuoleolata^ but with stronger plications. Apparently restricted in the Mohawk valley to one single bed in the upper part of the Lower Eel- derlerg formation,—In Pennsylvania, has been found on the Delaware river (G6, p. 134); on the JS. Branch Susquehanna in the Bastard limestone (G7, 101); in Bedford Co., near New Paris, Napier, on the weathered surface of cherty limestone in the upper part of the formation. (T2, pp. 88, 121.) VL.
