Lost Species: Great Expeditions in the Collections of Natural History Museums

With Kemp as our guide, we go spelunking into museum basements, dig through specimen trays, and inspect the drawers and jars of collections, scientific detectives on the hunt for new species. We discover king crabs from 1906, unidentified tarantulas, mislabeled Himalayan landsnails, an unknown rove beetle originally collected by Darwin, and an overlooked squeaker frog, among other curiosities. In each case, these specimens sat quietly for decades—sometimes longer than a century—within the collections of museums, before sharp-eyed scientists understood they were new. Each year, scientists continue to encounter new species in museum collections—a stark reminder that we have named only a fraction of the world’s biodiversity. Sadly, some specimens have waited so long to be named that they are gone from the wild before they were identified, victims of climate change and habitat loss. As Kemp shows, these stories showcase the enduring importance of these very collections.
