Chamaesipho columna is the type species for the barnacle genus Chamaesipho. Originally, species concept, as refined by Darwin472 consisted of C. columna. Spengler's 1790 description included specimens from "Otaheite" (Tahiti), which were far larger than any of the three described species. As Chamaesipho is restricted to Australia and New Zealand, and Spengler's Tahiti material lacked opercular plates, it is no longer included as Chamaesipho. Spengler's written description agrees with Chamaesipho.472 Spengler's Tahiti material is thought to be New Zealand Epopella, mislabeled.
