Museums hold 248 specimens collected within 10 miles of Mount Saint John between 1839 and 1975: 221 Animalia, 11 Fungi, 10 Plantae, 5 Protozoa, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. H. Bauer, A.R. Gaufin, H.H. Ross, Arden R. Gaufin 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.
