Foraminiferal tests can be found ai nearly any point where a piece of 

 this limestone is chipped. The genus Lepidocyclina (Orbitoides) pre- 

 dominates. Generally, these fossils are found most thickly near the base 

 of the upper white limestone, they are much larger in this situation than 

 in the upper horizons and T believe them to be of quite a different species. 

 The two best localities in which to find these Orbitoides are at Mount 

 Lantauan, near the large sink hole at the eastern end of the ridge, and at 

 320 meters (1,050 feet) elevation on the southwest slope of Mount Licos, 

 where the trail passes around to the coal workings. 



Another characteristic form found in this limestone is the marine 

 alga Lithotliamnium ramossisium Eeuss. This is shown'' in two sections 

 on Plates III and IY. 



There seems to be little question but that this is the same horizon as 

 the Baguio, Theila Pass, Binangonan and Masbate upper limestones. 

 Following Martin 5 in his work on Java, and Newton and Holland 6 on 

 Formosan fossils, I have been inclined to assign this formation, at least 

 this horizon of it, to the Miocene, although fossils from a very similar 

 limestone which I have also examined in the field in Batan Island have 

 been classified by a European paleontologist " as Oligocene. The fossils 

 so classified were collected by Mr. 0. Halvorsen Beinholt and he simply 

 states that they came from above the coal. However, I suspect, judging 

 from similar forms which I collected myself on Batan Island, that his 

 forms did not come from the uppermost horizon, therefore, future search 

 and study of the fossils already collected may reveal this Oligocene horizon 

 in Cebu. 



It will be of interest to attempt to correlate our Cebu section with 

 Verbeek's 8 classification of the Eocene in Java as amended in 1892, which 

 is as follows : 

 Stage IV. Orbitoides — Miocene. 



III. Marl sandstone — Oligocene. 

 II. Quartz-sandstone — Eocene. 

 I. Breccia stage — basal conglomerate. 



This scheme is more in accord with Martin's idea as expressed in 1900, 

 as follows : 



Quaternary; consisting of ftuviatile and marine deposits, the latter rich in 

 Mollusca, and at some localities remains of whales. 



Upper Pliocene; represented by the Rendon Beds, rich in remains of Stegodon 

 and Gervus, 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
