Museums hold 615 specimens collected within 10 miles of Waterloo between 1895 and 1975: 604 Animalia, 6 Fungi, 3 Unrecorded, 1 Plantae, 1 Chromista. 12 distinct Species records are shown. Collected by C. A. Petrovic, C. H. R., Caldwell 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.
