The Cloez Collection, a taxonomic collection of invertebrates from the
Paris Basin Eocene.
A comparative collection of over 500,000 Recent mollusks including modern
extinct and endangered land mollusks from California. Much of the
collection was acquired prior to 1925 and therefore is of historical value.
The emphasis of the collection is on marine and non-marine mollusks of
the eastern Pacific from Chile to northern Alaska and east to the continental
Recent Scleractininan corals from the Pacific Basin and the Caribbean,
especially the Pacific coast of the Americas.
