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 : 83

“ Melania wahlamatensis Lea ”

This was correctly listed as a nomen nudum ( Frest & Johannes 2010), but only on the authority of Graf (2001), who attributed it to Binney (1860) while noting that Hannibal (1912: 178) gave the authority as “‘Lea,’ Carpenter, 1857 (nude name)”. Indeed, the first mention we can find is Carpenter (1857: 211, 325), who listed it from the Sacramento River and credited it to a draft manuscript of Gould on the U.S. Exploring Expedition shells. Given the locality, it would be referable to J. occata , not a “form of plicifera ” as speculated by Frest & Johannes (2010). The name was listed by Taylor (1975a) as Juga wahlamatensis with no indication that it was not an available name.
