Check list of recent Utah Mollusca

The "Descriptive Catalog of the Mollusca of Utah" appeared in print in 1929, the product of the senior author and Dr. David T. Jones. In recent years molluscan work has been carried on at the University by Dr. Jones and his co-workers, notably Elmer G. Berry, Edward Lovvrance, Jack P. Woolstenhulme and the present junior author. Since 1945 the latter has been collecting data w ith a view toward a thorough-going revision of the 1929 work. Such a revision has been necessitated by the number of new forms described from the state, the revision of several im portant groups of mollusca by several authors, the work of other western alacologists, especially in the inter mountain area, and the recent concepts in taxonomic work.
