Mansfield (1930) described the Jackson Bluff (Chocatawahatchee) Formation species as Ecphora qudricostata umbilicata. Campbell (1993) and Lauck Ward (personal communication) agree that all named species and subspecies of Ecphora from the Upper Pliocene are variations of a single species E. quadricostata. Both consider Ecphora bradleyae Petuch, 1986 as the only other valid Upper Pliocene Ecphora. Reference Campbell, Lyle. 1993.
