12-Month Finding on a Petition To List 14 Aquatic Mollusks as Endangered or Threatened

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the basalt juga (Juga new species (n. sp.) 2), canary duskysnail (Colligyrus convexus), cinnamon juga (Juga n. sp. 3), Columbia duskysnail (Colligyrus n. sp. 1), Fredenburg pebblesnail (Fluminicola n. sp. 11), Goose Valley pebblesnail (Fluminicola anserinus), Hat Creek pebblesnail (Fluminicola umbilicatus), Klamath Rim pebblesnail (Fluminicola n. sp. 3), knobby rams-horn (Vorticifex n. sp. 1), masked duskysnail (Colligyrus n. sp. 2), nugget pebblesnail (Fluminicola seminalis), Potem Creek pebblesnail (Fluminicola potemicus), Shasta pebblesnail (Fluminicola multifarius), and tall pebblesnail (Fluminicola n. sp. 2) as endangered or threatened, and to designate critical habitat, under the Endangered Species Act of 1973, as amended (Act). The Fredenburg pebblesnail and the Klamath Rim pebblesnail were referred to in the petition and in our 90-day finding (76 FR 61826) as the nerite pebblesnail and the diminutive pebblesnail, respectively (see Clarification Regarding Common Names for Two Petitioned Aquatic Mollusks, below). After review of the best available scientific and commercial information, we find that listing the basalt juga, cinnamon juga, Columbia duskysnail, Fredenburg pebblesnail, Klamath Rim pebblesnail, knobby rams-horn, masked duskysnail, and tall pebblesnail is not warranted at this time because these snails do not constitute listable entities under the Act (see Listable Entity Evaluation, below). We ask the public to submit to us new information that becomes available concerning the taxonomic status of these mollusks. We find that listing the canary duskysnail, Goose Valley pebblesnail, Hat Creek pebblesnail, nugget pebblesnail, Potem Creek pebblesnail, and Shasta pebblesnail is not warranted at this time. We ask the public to submit to us new information that becomes available concerning threats to these mollusks.
