This action is based on a review of the best available scientific and commercial information, which indicates that these species are no longer extant and, as such, no longer meet the definition of an endangered species or a threatened species under the Endangered Species Act of 1973, as amended (Act).","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF THE INTERIOR","name":"Interior
