We, the U.S. Fish and Wildlife Service (Service), propose to list the Jamaican kite swallowtail (Eurytides marcellinus), a butterfly species from Jamaica, as an endangered species under the Endangered Species Act of 1973, as amended (Act). After a review of the best scientific and commercial data available, we find that listing the species is warranted. If we finalize this rule as proposed, it would add this species to the List of Endangered and Threatened Wildlife and extend the Act's protections to the species.
