Collected by A. Gray; W. S. Sullivant, A. R. Gaufin, A. R. Gaufin, H. H. Ross 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.
