Bulimulus eos is endemic to Santa Cruz Island in the Galápagos Islands. It was not found alive over the past three years of collecting on Santa Cruz Island. It may already be extinct. The range of the suitable habitat for this species is likely to be less than 100 km². The flora and fauna of Santa Cruz Island has changed considerably since human settlement. The range of suitable habitat for land snails on this island has certainly declined accordingly.
