New records of mollusca

Recent work on the molluscan collection of the University of Utah, involving the transferring of sets from the accession lots to the systematic series and the cataloging of the new accessions to the museum, has brought out several unpublished records and many gifts of recent date. Among the former are records of Dr. R. V. Chamberlin from the western deserts of Utah, and also from Idaho and Yellowstone National Park; the records of Willis Gertsch from the east shore of Bear Lake; and of Elmer Berry from the Raft River Mountains. Among the recent gifts are the important accessions of Dr. Walter Cottam from the Aquarius Plateau of southern Utah, of Kenneth Brizzee from the Humboldt River Valley of Nevada, and of several sets from the Uinta Mountains, some of which were Collected by Mary Lou Thorne, others by the author.
