Revision of Scissurellidae , Anatomidae and Fissurellidae (G astropoda: V etigastropoda) from the Plio-Pleistocene of the Philippines.

The taxonomy, paleo-ecology and biogeography of the highly diverse "Cabarruyan" fauna are explored further. Eight species of three vetigastropod families are discussed here, one of which is described as new: Zeidora geigeri nov. spec. The other seven species were previously described from Recent material and three of these are also known from other fossil deposits. Most of the species still occur around the Philippines today.
