ABSTRACT. Despite Chief of the Illinois Natural History Survey, Stephen Forbes' early attempts at preventing the Field Museum of Natural History (FMNH) ichthyologists from collecting fishes in Illinois, the fourth largest fish collection in North America, the FMNH, has one percent of its fishes, in number of lots and number of specimens, from Hickory Creek Basin, Des Plaines River Drainage, Illinois. Ecologist Victor Shelford conducted his early experiments on stream succession of fishes at Hickory Creek. Edward Nelson, Seth Meek, Carl Hubbs, Alfred C. Weed, Hurst Shoemaker, Loren Woods, Pearl Sonoda, Margaret Bradbury, Larry Page, Francis M. Veraldi, and Philip W. Willink, have all collected fishes from Hickory Creek. In 1977 to 1982, the authors collected Hickory Creek fishes from 33 stations bringing the total fishes examined to 858 lots, and 13,072 specimens housed in the FMNH. An additional 253 lots and 3207 specimens from Hickory Creek were tabulated from other fish collections (ANSP, INHS, JLBS, UMMZ). A total of 60 species from 11 families and 9 orders have existed within Hickory Creek Basin.  Broken down into 10 historical periods, the number of species, 39, found in 1907 to 1909 corresponds with the 38 species found between 1977 to 1982. Two Illinois endangered species, Notropis anogenus, and N. heterolepis, and one Illinois threatened species, N. heterodon, are apparently extirpated from Hickory Creek.  The known range of the shortnose gar, Lepisosteus platostomus (ANSP 37651), once reported from Joliet, Illinois, extends the known range from Peoria Lake northeast by several hundred miles.  An incursion of southeastern Illinois fishes into Hickory Creek basin may have occurred in the late 1930's and early 1940's and the possible causes are discussed.
