One new genus and thirteen new species of Mollusca are described from the Upper Cretaceous fauna of the Santa Ana Mountains, southern California. New generic assignments based upon discovery and study of previously unobserved structural features are offered for a number of common and well-known Cretaceous molluscan species. Some genera hitherto unknown in the Upper Cretaceous of the Pacific Coast are recognized, and their affinities are discussed.
