Types of late Cenozoic fossil gastropods that are in the Illinois State Geological Survey collections are listed, illustrated by photographs, and accompanied by essential data, including catalog number, original description, type locality, and name of collector. Of the 34 types, all were described by Frank Collins Baker, except the one species from loess deposits in Illinois described by H. A. Pilsbry. A brief outline of Baker's scientific activities and a selected bibliography of his studies of fossil gastropods are included. THE FRANK COLLINS BAKER COLLECTIONS The molluscan materials that Frank Collins Baker studied during his professional life of more than fifty years are widely dispersed among several collections. Baker began his study of Mollusca as a Jesup Scholar at the Academy of Natural Sciences in Philadelphia ; in this capacity he took part in a scientific expedition to Mexico sponsored by the Academy in 1890. The next two years (1891-92) Baker spent at Ward's Natural Science Establishment, Rochester, New York, where he was in charge of the invertebrate collections. The following year he assisted in setting up Ward's scientific exhibits for the Chicago World's Fair. He remained in the Middle West to become Curator of Zoology in the Field Columbian Museum of Natural History, Chicago, but after one year accepted the position of curator in the museum of the Chicago Academy of Sciences, where he remained from 1894 to 1915. The museum of the Chicago Academy of Sciences houses the collections upon which Baker based his "Mollusca of the Chicago Area" (1902). "Lymnaeidae of North and Middle America" (1911), written while Baker was at the Chicago Academy, was based largely upon his private collections of gastropods of that family, collections that the Smithsonian Institution acquired after his death. After spending two years as a special zoological investigator at the University of Syracuse in New York, Baker became Curator of the Museum of Natural History at the University of Illinois in 1918, a position he held until his retirement as Curator Emeri-
