The Chicago Academy of Sciences herpetology collection includes over 22,000 specimens, primarily preserved in alcohol. Approximately 60% of the specimens are reptiles and 40% are amphibians. The Midwest is strongly represented, as are Arizona and southeastern United States, thanks to multiple Academy expeditions during the mid-1900s. The collection contains many para- and holotypes, as well as one subspecies type specimen, of the Northern Crawfish Frog (Lithobates areolata circulosa). Notable collectors include: Knox Conant, Hudson Conant, Richard A. Edgren, Howard K. Gloyd, R. L. Hutchison, Betty Komarek, Edwin V. Komarek, Roy V. Komarek, Walter L. Necker, and Orlando Park.

Additional Metadata Rooted in Chicago, Illinois, the Chicago Academy of Sciences was founded in 1857 and was the first science museum in Chicago. Through its Peggy Notebaert Nature Museum, the Academy connects its community to local environments and inspires life-long relationships with urban nature. The museum collections and archives contain natural history collections in the disciplines of botany, entomology, geology, herpetology, malacology, mammalogy, oology, ornithology, and paleontology, as well as cultural collections, audio visual collections, and archives. These materials range from the 1830s to the present and are predominantly from North America with a focus in the Midwest/Western Great Lakes region.
