Strong, Ellen E., Garner, Jeffrey T., Johnson, Paul D. & Whelan, Nathan V., 2022, A systematic revision of the genus Juga from fresh waters of the Pacific Northwest, USA (Cerithioidea, Semisulcospiridae), European Journal of Taxonomy 848, pp. 1-97 : 81

“ Goniobasis plicifera var. leai Hemphill, 1890 ”

This was correctly listed by Frest & Johannes (2010) as a nomen nudum, but only on the authority of Coan & Roth (1987). This name was listed in Hemphill’s (1890: 18) catalogue of North American shells for sale as originating from “ Oregon ”. Taylor (1975a) included it as Juga leai with no indication that it was not an available name. Wu & Brandauer (1982) listed “cotypes” UCM 17779 and UCM 17780 collected by H. Hemphill from the Willamette River in Oregon, which have no type status ( Coan & Roth 1987). Given the locality, the specimens would be referable to J. plicifera as circumscribed here, not J. (J.) plicifera oregonensis as suggested by Frest & Johannes (2010).
