XIII and \ t HISTORICAL NOTES. 453 ing note, entitled Corrections of the geological maps of Oregon,was published:1 In the existing geological maps of Oregon the Coast Range is represented as com-posed of Archean rocks. This is a serious error. Professor Newberry has alreadystated (U. S. Pacific R. R. Surveys, Vol. VI, Pt. II, p. 29) that the fossils of therange are of an age not older than the Miocene. The unpublished notes of Profes-sor Condon, formerly State geologist, state that the backbone of the Coast Rangeconsists of argillaceous shales, which contain invertebrate and vertebrate fossils,frequently in concretions. Some of the latter are Physoclystous fishes, with stronglyctenoid scales. To this formation Dr. Condon gives the name of Astoria this is an extensive Tertiary deposit, rich in Mollusea, which is usually inter-rupted by the central elevations of the mountain axis.
