COELENTERATA, ETC. 
Echinoid spine. Cycloseris sp. 
Flabellum cf. australe Moseley. Three other coralline forms. 
Balanophyllia. Vermes sp. 
All the forms specifically identified are Recent species. The two forms 
Flabellum cf. australe Moseley and Balanophyllia also occur in Moody’s 
locality 314, Agusan Valley, Agusan Province, where they are associated 
with— 
GASTEROPODA 
Cassis sp. Nassa canaliculata Lamarck. 
Cyclonassa elegans Kiener. Cerithium jonkeri K. Martin. 
Nassa globosa Quoy. Turritella terebra Lamarck. 
Nassa crenulata Lamarck. Turris carinata. 
PELECYPODA 
Arca ferruginea Reeve. Balanophyllia. 
Paphia striata Chemnitz. Cycloseris sp. 
Flabellum cf. australe Moseley. 
The form Flabellum cf. australe Moseley is identical with the species 
listed by Warren D. Smith from near Aroroy, on the west side of Aroroy 
Bay, Masbate, Bureau of Science locality F907, where it has a similar 
association as indicated above. The Balanophyllia may be an extinct 
species and the writer regards the association of these forms with similar 
assemblages of Gastropoda and Pelecypoda as not merely adventitious 
but indicative of essential synchrony. In other words, the Banisilan 
formation is equivalent to the beds exposed at Aroroy and the nearly 
horizontal beds at Moody’s locality 314 in Agusan Valley. The latter 
are probably equivalent to beds referred to the Pliocene by Martin. Mar-
