Of the determinable fossils in these and the following lists, those which 
represent living species are indicated by a plus sign. 
Fossils were obtained from the Cudiapi sandstone at three different 
places, as follows: (1) Fossil locality 65, calcareous sandstone immediately 
beneath the Upper limestone in the hills north of Malumbang Plain, ad- 
jacent to fossil locality 61; (2) fossil locality 4, calcareous sandstone 
beneath the Upper limestone about 450 meters south of Balinsog Hill, at 
an elevation of 360 meters; (3) fossil locality 18, sandstone, at an ele- 
vation of 270 meters on the high ground between Apad and Milipilijuan 
Creeks, affluents of the Bahay River. The Upper limestone does not occur 
over the sandstone at this place, but the sandstone itself is very calcareous. 
The fossils from the Cudiapi sandstone were determined as follows: 
From fossil locality 65. 
Dosinia sp. Schizaster subrhomboidalis Herk- 
Pecten sp. lots. 
From fossil locality 4. 
Turbo sp. Pleurotoma sp. 
Nassa sp. Melania sp. 
Fusus sp. 
From fossil locality 138. 
Clementia sp. Cerithium herklotsi K. Martin. 
Xenophora dunkeri K. Martin. _ Pleurotoma tjemoroénsis K. Mar- 
Ostrea orientalis Chemnitz. (?) + tin. 
Pecten senatorius Gmelin. + Pleurotoma carinata Gray. + 
Fossils from limestone at a horizon corresponding stratigraphically with 
that of the Lower limestone were collected at three localities, namely: 
Fossil locality 44, at the mouth of Ayoni [Yuni] River; fossil locality 59, 
on a prominent hill (elevation, 250 meters) 2 kilometers west of Tala; 
and fossil locality 25, near Tambo, a barrio of San Narciso. However, 
as will appear in the discussion of the field relations at these localities, 
only the last group in the foregoing list represents certainly the Lower 
limestone; the fossils from the other localities may belong to either the 
Upper or Lower limestone.
