摘要

We, the U.S. Fish and Wildlife Service, designate critical habitat for the Pecos assiminea (Assiminea pecos), Roswell springsnail (Pyrgulopsis roswellensis), Koster's springsnail (Juturnia kosteri), and Noel's amphipod (Gammarus desperatus), under the Endangered Species Act of 1973, as amended. In total, we are designating as critical habitat approximately 521.3 acres (211.0 hectares) for the four species of aquatic invertebrates. The critical habitat is located in Chaves County, New Mexico, and Pecos and Reeves Counties, Texas.
