This report supplements those of W.A. Oliver, Jr. (dated 8/18/59) and Serge Mamay (dated 6/1/59). Additional brachiopods and molluscs in collections 58(?)AMr387 permit a refinement of the age designation of that collection. It is either of latest Middle Devonian or earliest Late Devonian age. Collection 58AL88 contains linguloid brachiopods, perhaps assignable to the genus Barroisella, that suggest a Middle or Late Devonian age. E&R report prepared by J.T. Dutro, Jr., in consultation with E.L. Yochelson
