45. Limestone ridge 2 kilometers west of the city hall and north of the 



observatory, Baguio, Benguet. This bluish to white limestone is 

 very rich in poorly preserved fossils; the characteristic species 

 is Turbo borneensis. It is probably upper Miocene or early 

 Pliocene. This is the uppermost limestone in the Benguet district. 



46. Benguet Road, Mountain Province, Luzon; 2 kilometers above Twin 



Peaks. This is a very hard, light- to brown-colored formation; 

 probably Miocene at this point. 



272. On south slope of Mount Mangilao near Danao. This locality is 



at the base of the upper limestone and at the summit of a lower 

 limestone horizon. There is a marl below this which is ap- 

 parently unfossiliferous. The fossils were picked up where they 

 had already weathered out of the formation; elevation about 200 

 meters above sea level. 



273. This is a yellow marl found in Sibod Gulch, Naga, Cebu; probably 



Miocene. 



274. Talamban near Panopoy; upper limestone, white and irregular. 



275. Opan on Mactan Island, Cebu; Recent raised coral limestone. 



276. An upper coral bed on Mactan near Cebu. 



277. Soft white chalky limestone cliffs on the Minanga River, Cebu, 



Toledo Road near Camp One. This is probably Pliocene limestone. 



278. Hard buff-colored limestone above the coal seams at Guilaguila, 



Cebu; contains numerous Foraminifera. 



279. Cotabato Valley near Mount Uling, Cebu; limestone. 



280. Malbog, Alegria, Cebu; Pliocene limestone. 



281. Limestone near oil horizon, 500 meters above sea level, Alegria, 



Cebu. 



282. Mangilao; white limestone just above coal at Carmen, Cebu. 



283. On the road between San Fernando and Naga, Cebu; float specimen. 



284. Limestone; specimen given me by a native woman in Toledo, Cebu; 



locality unknown. 



285. Cumajumayan Hill; Cebu. No limestone on top of this hill, but 



the fossils are from a limestone formation which has since been 

 removed. 



286. Upper limestone, Lantauan Ridge, Cebu. This contains the char- 



acteristic alga Lithothamnium. 



287. Travertine; in the stream in Cumajumayan Valley, Cebu. 



288. Cabecelino Creek, Cebu. 



289. Shale beds above the coal at Compostela, Cebu. 



293. Cream-colored rather open limestone; Cotabato Hill, Mindanao. 

 This limestone is rich in fossils which are upper Miocene or 

 Pliocene. 



356. Cut in the road between Laoag and Bacarra, Ilocos Norte, Luzon. 

 Unconsolidated gray to white sandy marl; fossils in some cases 

 retain original color; very rich in perfectly preserved shells; 

 deposit is undoubtedly Recent. 



609. On the beach, northeast coast of Semirara Island. Fossils evidently 

 weathered out of limestone. Collected by H. D. McCaskey. 



778. Cave near the beach at Puerto Princesa; recent limestone. Collec- 

 tions by C. M. Weber.
