Museums hold 155 specimens collected within 10 miles of Caldwells Addition between 1894 and 1975: 152 Animalia, 3 Fungi. 12 distinct Species records are shown. Collected by Daiber, F. C. (Frank C.), Daiber, F. C. (Frank C.), Langlois & Kinney, E. C. (Edward Coyle), E. E. Bogue and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
