Locality 5x, Philippine Islands, Luzon, Tayabas Province, Bon- 
doc Peninsula, west side of Ragay Gulf, Bahay River ; 300 meters 
east of the mouth of Apad Creek in lignitic gray sandstone 
which was deposited in brackish water. Coll., Roy E. Dickerson. © 
This yielded the species listed below. 
Species from locality 5a. 
GASTROPODA 
Cassidaria. Strombus (?) sp. 
Cerithium jenkinsi K. Martin. _ Telescopium telescopium Linnssus; 
Cerithium sp. nov. living. 
Conus loroisii Kiener; living. 
PELECYPODA 
Arca tenebrica Reeve; living. Ostrea sp. 
Chione (7?) sp. Amber and petrified wood. 
This fauna was made up largely of Cerithium jenkinsi K. 
Martin, Cerithiwm sp. nov., and Ostrea sp. The other forms 
are represented by only one or two species which were 
probably carried across the sand bar by small crabs that sidled 
over the sands of the Vigo Sea. The abundance of carbonaceous 
material and the occurrence of amber and petrified wood also 
indicate that conditions of deposition here differed from those 
in the previously described localities.
