## Abstract

We, the U.S. Fish and Wildlife Service (Service), determine endangered species status under the Endangered Species Act of 1973 (Act), as amended, for the fluted kidneyshell (Ptychobranchus subtentum) and slabside pearlymussel (Pleuronaia dolabelloides). These two species are endemic to portions of the Cumberland and Tennessee River systems of Alabama, Kentucky, Mississippi, Tennessee, and Virginia. The effect of this regulation is to add these species to the List of Endangered and Threatened Wildlife and to implement the Federal protections provided by the Act for these species.
