In 1892 fossil evidence forced him to change his opinion as to ft and y, or III and IV, and he referred the lower of these to the Oligocene and the latter of them to the Upper Miocene2 thus reaching much the same opinion as Mr. Martin had expressed. While this report was in preparation, Mr. Martin published a paper on the division of the f ossilif erous strata of Java, which he classifies as follows:3 Quaternary; consisting of fluviatile and marine deposits, the latter rich in Mollusca and at some localities in remains of whales. Upper Pliocene; represented by the Kenden beds, rich in remains of Stegodonand Cervm, containing also Pithecanthropus erectus Dub. Pliocene-Miocene, or the Java series, possibly including some pre-Miocene rocks. This constitutes the greater part of the Island of Java and most of the fossils from the island which have been described come from it. Among them are Lepidocyclma and Cycloclypeus. This series extends northward through the Philippines to central Japan. Eocene; marine beds of small extent with nummulites, Alveolina and Orthophragmina. They contain coal. Cretaceous limestone with Orbitolina from Banjumas. This rock is not known to exist at any other point in Java. For the purposes of Philippine geology it is important to remark that the series which carries the black lignites accompanied by quartzose sandstones, has been regarded by all the geologists cited, and by most others, as Eocene; while there appears to be a gap in the Miocene of the Sunda Islands which may correspond to an unconformability there, and which answers to a very pronounced discordance in the Philippines. The Tertiary of the Philippines is fairly well developed, but very insufficiently investigated. In presenting his determinations of the BECKER Ma...
