| 概要 |
In this report are treated with the faunal analysis, age correlation, and systematic description of the gastropods from the younger Caenozoic formations in the Iloilo basin, Panay Island, the Philippi...nes. It is one of the results of the activities of the Association for Palaeontological Research in Southeast Asia. The molluscan samples were obtained along the eastern section of the basin at five localities representing respectively different stratigraphic horizons. The molluscan assemblages belong to the shallow to deep shelf faunas of the Indo-West Pacific zoogeographical province. The age of the five assemblages ranges from Mio-Pliocene to Plio-Pleistocene. The discrepancy of the results of the intra- and inter-regional correlations by means of the molluscs and the planktonic foraminifers is discussed in some details. Systematical descriptions of total 136 gastropods include 10 new genera and subgenera,31 new species and subspecies, and one new name. The taxonomical discrimination is based chiefly on the detailed features of the morphological development from the veliger to adult illustrated on the protoconch and teleoconch.続きを見る
