with a feldspar that acids decompose completely, may be a tuff coming 
from a similar porphyry. In the bed of Sogoton River north of Basey 
are bowlders of talc- and chlorite-rocks. . 
The Sogoton cave is formed of calcareous cliffs in which one recognizes 
traces of bivalves and spines of echinoderms. In front of the grotto are 
situated, at a height of 20 feet [about 6 meters] above the river on the 
right bank, banks with marine shells. There are species still living; 
according to Dr. von Martens, Venus (Hemitapes) hiatina Lam., Arca 
(Scapharca) cecillei Phil., Arca uropygmelana Bory, and Placuna placenta 
L. The shells scarcely adhere to the tongue; therefore, the deposit must 
be very recent. On one of the small islands near Nipa-Nipa (Basey) are 
found, on the raised shell banks situated at a height of 60 feet [about 
20 meters] above sea level, the following living species (according to 
Dr. von Martens); Chama sulfurea Rv., Pinna, cf. nigrina Lam., Ostrea 
denticulata Born, O. cornucopiae Chemn., and O. rosacea Desch. On the 
coast west of Basey is an incoherent aggregate of shell fragments with 
isolated, rounded, small bowlders.

FOSSIL LOCALITIES, SAMAR ISLAND 
Locality F865—Catbalogan, 8.4 kilometers north of the town, on main 
road, south 40° west across bay from quarry and about 0.5 kilometer north 
of barrio of Maolong. Prominent exposure of gray sandstone overlaid 
by buff sandstone, with small normal fault in approximate center. Strike 
north 10° west, dip 6° northeast, with doubtful plunge of 4° northwest. 
Alternate layers of sandy material in sandy shale. Lower series contains 
small, poorly preserved fossils and some carbonaceous material, includ- 
ing pockets of amber. Small, thin laminew and strata average approxi- 
mately 15 centimeters. Deeply weathered. Upper series, compact, fine- 
grained, buff, caleareous sandstone, which is fossiliferous (contains Globt 
gerina) and carbonaceous. This locality is readily identifiable by fault. 
The height of exposure is about 6 meters, though in the immediate neigh- 
borhood this figure will vary from 0.5 to perhaps 10 meters. The road cuts 
nearly along the strike of beds. Collector, H. G. Schenck, November 1, 1920. 
Locality F866.—Catbalogan, on right bank of Antiao (Catbalogan) Ri- 
ver, between suspension bridge at north end of Calle del Rosario and mouth 
of river and continuing around Light House Point. Exposures of sand- 
stone varying in texture from sandy shale to buff, compact, hard sand- 
stone, each stratum averaging about 3 decimeters in thickness. Fossils 
small and poorly preserved, falling to pieces upon exposure. Strike east 
and west, dip 15° northeast. Small fault in exposure, dying out in upper 
beds. Beds exposed by tide; strike north 87° west, dip 21° northeast. 
Outcrops sandstone and shale upstream to point 200 meters from mouth 
have varying strike. Small, well-defined folds, making series of plunging 
anticlines and synclines, occur at locality. Collector, H. G. Schenck, Novem- 
ber 2, 1920. 
Locality F867.—Lepidocyclinal limestone on south-southwest side of 
quarry hill on beach approximately north 55° west from kilometer 2 post, 
Catbalogan North Road. Fine- to medium-grained sandstone, and sandy
